Sentinel V Features
The Sentinel V is designed for several-month autonomous current profile deployment from temporary or
permanent mounting in the ocean, near-shore, harbors, and lakes.
The Sentinel V Series ADCP consists of an ADCP, battery pack or individual D-cell batteries, microSDHC
memory card, and software. Both battery capacity and memory can be increased with upgrades for longer
deployments. The Sentinel V Series ADCP requires the addition of a Windows® compatible computer to
configure the ADCP and replay collected data.
Figure 1 and Figure 2 only show two of the options and models available with the Sentinel V
Series ADCP (see Available Options).
After a deployment, systems need to be cleaned thoroughly before the touch sensor will work.

Available Options
The following section explains the different options available for Sentinel V Series ADCPs. See the Parts
Location Drawings for more information.
•
Transducer – The standard nominal ranges are 20m (1000 kHz), 50m (500 kHz) and 100m
(300 kHz). See the Outline Installation Drawings for dimensions and weights.
•
Vertical Beam – an optional 5th beam is available.
•
End-Cap – The End-Cap consists of an IEEE 802.11b/g/n WLAN wireless communications
Touch Sensor and an optional underwater electrical connector.
•
End-Cap Connector – The optional connector can be straight or right-angled. See the Outline
Installation Drawings for end-cap configurations.
•
Internal Batteries – The Sentinel V can use either pre-assembled battery packs or 12 D-cell
batteries. The battery pack housing uses a pack of 36 D-cell alkaline batteries in series, physically
configured as three stacks of 12 cells for a nominal voltage level of 18 VDC. The D-cell battery
configuration housing uses 12 D-cell alkaline batteries in series, for a nominal voltage level of
18 VDC.
•
External Battery Case – The optional external battery case holds two pre-assembled battery
packs for a nominal voltage level of 18 VDC.
•
AC Adapter – The optional AC adapter provides 18 VDC.
•
Housing – The standard Sentinel V Series ADCP housing allows deployment depths to 200 meters. See the Outline Installation Drawings for dimensions and weights. The housing type and
length will depend on if it uses battery packs or individual D-cell batteries.
•
Memory – The Sentinel V includes a microSDHC memory card. There is no maximum memory
limit; Contact TRDI support for a list of supported memory cards.
•
Pressure Sensor – The pressure sensor (standard 30 Bar) measures water pressure (depth).

Computer Considerations
TRDI designed the Sentinel V Series ADCP to use a Windows® compatible computer. The built-in
ReadyV user interface configures the ADCP and data is displayed through TRDI’s Velocity program.
Minimum Computer Hardware Requirements:
•
Desktop, Laptop, or Netbook computer (see Table 1 for operating system)
•
Screen resolution above 1024x768 (see note)
•
Internet Brower (see Table 1 for supported browsers)
•
Mouse or other pointing device
•
Wireless 802.11b/g/n WLAN Interface
Many laptops and netbooks today have built-in WLAN. If not, then a WLAN adapter is required.
Most wireless enabled laptops will be automatically enabled. Consult the instruction manual for
your specific device if you are not sure how to do so.
Laptops running on Windows XP® may have display issues when using a screen resolution of
1024x768. A workaround is to change the zoom level in the browser so that the entire ReadyV
screen is visible.
ReadyV does not support Windows 8 Internet Explorer® 10 Metro browser. Users may need to
turn off their browser pop-up blockers (either built-in or third party) in order to access ReadyV.

Sentinel V Operation Manual
June 2013
Power Considerations
Use the following section to determine the power requirements for the Sentinel V Series ADCP.
•
The Sentinel V uses +18 VDC to operate.
•
Depending on the type of housing Sentinel V is configured with, the ADCP may use a battery
pack or individual D-cell batteries.
•
If the Sentinel V is configured with the optional end-cap connector, then external power can be
used. The voltage must be +12 to 20 VDC. The optional AC power adapter provides +18 VDC.
Transmitted Power
For the Sentinel V, a fresh battery provides +18 VDC. Batteries spend most of their life at a nominal voltage of +14 VDC. Using 18 VDC will increase the range by 5 to 10% depending on conditions.
Power on Cycle
The power supply or battery pack must be able to handle the inrush current as well. Inrush current is the
current required to fully charge up the capacitors when power is applied to the Sentinel V Series ADCP.
The capacitors provide a store of energy for use during transmit. The inrush current is as high as 0.8
Amps RMS at 9.2 VDC. The ADCP will draw this amperage until its capacitors are fully charged. If the
power supply or battery pack limits the current or the power drop on the cable is significant, then the
power on cycle will take longer. It can take up to three minutes. When power is applied, there is one long
beep followed by a short beep 10 to 15 seconds later. The power must not shut down during the inrush
current draw, as this may not allow the Sentinel V Series ADCP electronics to start.

The Sentinel V ADCP includes an 802.11b/g/n WLAN interface and a built-in user interface called
ReadyV. The Sentinel V Series ADCP acts as the server, along with the connected computer (laptop, tablet, or desktop computer) known as the client.
The ADCP’s DHCP server IP address is 192.168.0.2 or use the WLAN address http://SVnnnnn.adcp
(where nnnnn is the five or six character Sentinel V serial number shown on the product label).
If the computer does not include a built-in 802.11b/g/n WLAN interface, use a USB adapter.
Only one ADCP at a time may be connected. To switch to another ADCP, first disconnect, and
then reconnect to the next ADCP.
Using the Wireless Connection
To connect to the ADCP:
1.
Prepare the ADCP by connecting the battery. After power is applied (long beep), there is a 10 to 15
second delay before the network is available (short beep). The WLAN is available after power up
for two minutes.
Sentinel V battery packs are shipped inside the system but not connected. Connect the
battery and seal the Sentinel V before deployment.
Sentinel V with D-cells are shipped without batteries inside the system. Install the batteries
and seal the Sentinel V before deployment.
2. Start the wireless network device on the laptop if it is not automatically enabled. This may be a
built-in wireless connection on a laptop or a USB wireless adapter.
The screen shots in this manual were made with Windows® 7. Depending on the operating
system and wireless adapter type, your wireless screen may look different. These differences
do not affect the performance of ReadyV.

that the ADCP’s WLAN turns off before the connection is complete,
simply start from step 3 again.
a. Click on the wireless access-point icon ( ) in the
Windows® system tray or if using a wireless USB
adapter, start the adapter’s interface.
b. Click the Refresh icon ( ) or use the wireless
adapter’s interface to search for connections. A list
of available wireless networks will appear in the
window. Sentinel V ADCPs will show as SVnnnnn
(where nnnnn is the five or six character serial
number shown on the product label). Repeat step 3
if needed.
c.
Select the ADCP on the list by clicking it and then
click the Connect button.
d. The Connecting to a Network message appears.
e. If prompted to select a Home, Work, or Public network, click Cancel to close the page. The Set Network Location page is not needed.

Using the ReadyV Wireless Connection
The Touch Sensor is NOT a button! Just place a finger into the cavity to activate the sensor.
After power is applied (long beep), there is a 10 to 15 second delay before the network is
available (short beep). Wait for the short beep before trying to connect.
The ADCP’s WLAN is available after power up for two minutes. Placing a finger over the Touch
Sensor starts the WLAN for another two minutes. Once connected, the WLAN will remain on.
Each time the Touch Sensor is touched, a short beep should be heard.
Only one ADCP at a time may be connected. To switch to another ADCP, first disconnect, and
then reconnect to the next ADCP.
Once ReadyV starts, if no keys are pressed for five minutes, the ADCP will disconnect. After
waiting two more minutes, the ADCP will power down. Use the Touch Sensor to restart.
After a deployment, systems need to be cleaned thoroughly before the touch sensor will work.
Wireless Connection Common Issues
The ADCP does not appear on the list of devices:
The ADCP may have timed out. Place a finger over the Touch Sensor
again. There is a short beep indicating that the WLAN is enabled on
the ADCP. The ADCP’s WLAN will remain on for two minutes after
the short beep. It may take several attempts to connect.
Another computer may already be connected to the ADCP. Only one
computer may be connected to an ADCP at a time.
The ADCP does not have power – connect the battery. After power is
applied (long beep), there is a 10 to 15 second delay before the
network is available (short beep). Wait for the short beep before
clicking the Refresh icon ( ).
If the touch sensor is blocked with biofouling, thoroughly clean the
sensor cavity first (see Removing Biofouling).

There are no ADCPs on the list of devices:
Start the wireless network device on the laptop if it is not automatically enabled. This may be a built-in wireless connection on a laptop
or a USB wireless adapter.
Look for a hardware switch or special function key on the laptop that
can turn the wireless radio on or off. Consult the instruction manual
for your specific laptop if you are not sure how to do so.
If the computer uses an external wireless adapter, make sure the
adapter is working correctly and is attached and installed properly.
Try using a different USB wireless adapter.
The ADCP is connected, but ReadyV does not start:
Windows 7 may indicate it is connected and the signal strength is
excellent even if the wireless connection is lost due to the ADCP
going to sleep.
Click on the wireless access-point icon ( ) in the Windows®
system tray and click on the ADCP connected to. Click the
Disconnect button and then click the Connect button to reconnect
to the network.
The ADCP is on the list, but connection fails:
If the ADCP appears on the list but the laptop fails to connect to it,
Windows® 7 may have kept the name on the list because it connected to that network in the past. In other words, this does not mean
that the network is actually available.
Touch the Wireless Touch Sensor to start the network. Listen for the
two beeps: the first one confirms the sensor detected your finger and
the second beep confirms the wireless network is ON. Placing a finger over the Touch Sensor starts the network for two minutes. Try to
connect again.
If the touch sensor is blocked with biofouling, thoroughly clean the
sensor cavity first (see Removing Biofouling).
If there are no beeps, make sure that the ADCP is properly powered.

System Setup
Click on the System setup panel to change how the system will be set up during the deployment. Click
Save to save the settings or Cancel to return to the previous settings.
ADCP depth – Enter the depth of the ADCP. The ADCP uses depth in its speed of sound calculations. If
the pressure sensor is not available, then the ADCP will use this manual depth setting.
Salinity – Enter the salinity of the water. Fresh water is 0 and salt water is typically 35. Salinity is used to
calculate the speed of sound. The speed of sound is used by the ADCP to scale the velocity data properly. If
0 is entered when deployed in 35 salinity water, the data will have a 3% velocity estimate error.
Magnetic variation – Enter the angle between true north and magnetic north, where a positive value
means true north is east of magnetic north. As such, declination depends on geographic location. It also
changes very slowly over time. The compass default is to output magnetic heading.
For the greatest accuracy, TRDI recommends checking the National Geophysical Data Center
website (below) to find the declination angle based on the latitude and longitude:
http://www.ngdc.noaa.gov/geomagmodels/Declination.jsp
Heading adjustment – Corrects for a physical misalignment between the ADCP’s Beam 3 and the heading reference. Enter the heading alignment angle (referenced to Beam 3) used as a new zero reference for
heading output.
Water Profile Parameters
Click on the Water profile panels to change how the water profile will be set up during the deployment.
The Sentinel V ADCP can have two different water profiles. Each water profile can be set independently. If
there is one water profile, the Add second profile button appears. If there are two water profiles, click
the red X ( ) to delete a water profile. Click Save to save the settings or Cancel to return to the previous
settings.
Select profile – Use the Up/Down triangles to select a water profile from the list. Each water profile can
use a default setup or select Custom to enter parameters.
Page 22
Sentinel V Operation Manual
June 2013
The Standard deviation shows the expected standard deviation of the velocity data stored in
each ensemble being collected by the Sentinel V ADCP. Most users will want to minimize this
value so that they obtain the best data possible (i.e. data containing the least amount of noise).
Standard deviation is dependent on cell size, the Number of pings, Ambiguity velocity, and the
Bandwidth.
Range – Select the range to measure. The default value shown in Table 2 is based on typical range possible based on the system frequency. The actual maximum range is dependent on the absorption in the water based on the Sentinel V ADCP frequency, the water salinity, water temperature and the actual deployment depth of the ADCP.
Cell size – Sets the cell size. Adjust the cell size as necessary as recommended in Table 2. A larger cell
size decreases the standard deviation, but shallow water situations may need to use smaller cells to gather
more data points.
It is not recommended to set the cell size below the minimum or above the maximum range
shown in Table 2.
First Cell – The range from the transducer face to the middle of the first cell. The Cell size and the
Blank primarily affect where it is located.
Number of cells – Sets the number of depth cells. The value will be calculated based on the Range and
Cell size. The number of cells must be less than 255.
Blank – Moves the location of the first cell away from the Sentinel V ADCP transducer head to allow the
transmit circuits time to recover before the receive cycle begins. The default value is based on system frequency and it is highly recommended to use this value. Setting a value below the default blank distance
may show ringing/recovery problems in the first depth cells.
It is not recommended to set the blank below the default value shown in Table 2.
Table 2.

Ambiguity velocity – Ambiguity velocity represents the maximum relative velocity (Sentinel V ADCP
motion plus the maximum actual water velocity) the ADCP can measure along a beam. Select one of the
settings from the drop-down list. This must be set correctly to avoid ambiguity errors. Ambiguity velocity
is used to improve the standard deviation: The lower the value of the ambiguity velocity, the lower the
single-ping standard deviation.
Bandwidth – Sets the profiling bandwidth and sampling rate. Smaller bandwidths allow the ADCP to
profile farther, but the standard deviation is increased by as much as 2.5 times.

ADCPs need to have the urethane inspected after two to three years of field use. Many users are
not familiar with the early signs of urethane failure. The primary damage to the urethane is from
bio-fouling and long exposure to the water and sun. Damage occurs on the surface of the urethane and at the edge where the urethane bonds to the cups. By returning the system every two
to three years, TRDI can inspect it for early signs of urethane failure and repair it through our
Factory Maintenance Service. At the same time, TRDI will make any necessary upgrades to
boards, assemblies, and firmware. This routine service period, proper care, and general maintenance ensures optimal Sentinel V ADCP performance.

Using Download Managers
Based on the deployment setup parameters such as ping interval, number of bins, etc., and the duration of
the deployment, the size of the data file to be downloaded from the Sentinel V ADCP can be in the order of
gigabytes. While downloading a large data file from the Sentinel V, the user may close the browser by mistake or the ADCP may disconnect. In order to recover the data file download from such situations, TRDI
recommends using a FireFox® download manager add-on called FlashGot®. This add-on will help resume downloads from the last point where the partial download left off. Using FlashGot, users may also
configure the maximum download speed using any internal and most external download managers.
Although ReadyV file downloads will work on most external download managers and most
browsers (see Computer Considerations for supported platforms), TRDI recommends using the
latest version of Firefox® (http://www.mozilla.org/en-US/firefox/new/) and the FlashGot®
plugin (https://addons.mozilla.org/en-US/firefox/addon/flashgot/developers).
Once FlashGot® is installed; when a data file is downloaded the following popup is observed:
Select the FlashGot option and click OK to download the file.
It may be noted that even though there are FlashGot extensions and plugins for other browsers
such as Google Chrome® etc., TRDI has not tested the efficacy of the FlashGot plugin in other
browser environments.

Mounting the Instrument
The preferred method of mounting the Sentinel V is using clamps that grip the circumference of the housing. The fallback method of mounting the instrument is to use the holes on the end-cap. See the Outline
Installation Drawings for dimensions.
When clamping the Sentinel V to a mount, the clamp must not have a large gap between the front and rear
clamp. Using this type of design can cause the housing to deform or even break if the clamps are over
tightened. This will cause the ADCP to flood.
Design clamps that fully surround the housing. Design the gap as small as possible so that when the clamp
is fully tightened it will not deform the housing or cause excessive pressure on the housing.
Poor Design
Good Design
Figure 15.
Figure 16.
Mounting the Instrument
Example Sentinel V End-Cap Mount
Use M6x1.0 bolts.
Only use stainless steel hardware.
The maximum thru-hole diameter in the mounting plate is 6.85 mm (0.270 inch). Using a larger
thru-hole could result in the threaded metal inserts on the end-cap being pulled out of the
plastic end-cap.

WorkHorse to Sentinel V Mount Adapters
TRDI has designed two adapters to use an existing WorkHorse mount with the Sentinel V. The
81D-5000-xx adapter (where xx is available for different length housings) includes sleeves to make the
Sentinel V fit into a clamp designed for Workhorse ADCPs. The rubber sleeves are textured on one side to
provide a better grip on the ADCP and include adhesive on the other side so that the customer can either
glue it to the instrument or their clamp. The 81D-5001 kit is a delrin plate with WorkHorse end-cap hole
pattern.

Connecting Cables and Dummy Plugs
Sentinel V ADCPs can be purchased with the optional end-cap connector using either the right-angle or
straight connectors.
The dummy plugs should be installed any time the cable is removed. Use the dummy plug when
the Sentinel V ADCP is in storage or is being handled.
To Disconnect the Cable or Dummy Plug:
1.
Turn the locking sleeve counterclockwise until it is fully loose and slides back.
2. Grasp the cable or dummy plug close to the housing and pull the cable or dummy plug straight out
away from the connector.
Figure 19.
Removing the End-Cap Connector Dummy Plug
To Connect the Cable or Dummy Plug:
1.
Spray lubricant on the rubber portion of the connector pins. This will help seat the connector.
Use light amounts of aerosol silicone (dry type) lubricant (such as from 3M) to help seat the
cable connectors and to protect the neoprene rubber from deterioration. Regular lubrication
is required.
2. Insert the dummy plug / cable onto the connector, rotating it until the keyed portions are properly
aligned. While keeping a slight inward pressure on the cable connector and ensuring that the connector is straight, thread the locking sleeve onto the receptacle to complete the connection.
Do NOT use any tools to tighten the locking sleeve ring. It should only be “finger tight”.

Connecting the External Battery Case
Sentinel V ADCPs can be purchased with the optional end-cap connector and an external battery case.
The dummy plugs should be installed any time the external battery case cable is removed. Use
the dummy plugs when the Sentinel V ADCP is in storage or is being handled.
To connect the external battery case:
1.
Remove the dummy plugs on the Sentinel V and external battery case (see Connecting Cables and
Dummy Plugs).
2. Connect the external battery case cable.

Using an Over-the-Side Mount
The over-the-side mount is common when the ability to move the Sentinel V ADCP from one platform to
another is needed. The mount must be as rigid as possible to limit the amount of pitch and roll applied to
the ADCP. Although the tilt sensor can measure a ±90° influence, anything beyond 15° will cause bias to
the data that cannot be removed. No matter what mounting type used, the ADCP must be below the bubble layer. Bubbles will cling to the urethane faces of the ADCP and reduce the range to almost nothing.
Usually a mount somewhere aft of amidship is used. A stern mount will cause all sorts of problems due to
propeller wake, bubbles and turbulent water conditions.
Our transducer assembly is sturdy, but TRDI did not design it to withstand collisions with all
floating objects. TRDI strongly suggests protecting the Sentinel V ADCP if this is a possibility.
Avoid using ferro-magnetic materials in the mounting fixtures or near the Sentinel V ADCP.
They affect the compass. Use titanium or 316 stainless steel hardware.

•
•
Test the Sentinel V ADCP

Example of an Over the Side Mount
Hand winch with cable or rope.
2. Boat cleat to tie off the lower end of the rotating arm.
3. Rotating arm. The rotating arm has to be strong to prevent vibration of the instrument which can
cause false data readings and it must be non-magnetic to avoid interference with the compass.
4. Pivot housing.
5. Instrument clamps (see Mounting the Instrument).
Over-the-Side Mounting Special Considerations
Use the following suggestions when mounting the Sentinel V ADCP to a platform.
•
It is desirable to rigidly mount the Sentinel V ADCP to the platform. Avoid the free spinning of
the ADCP in this application. The ADCP must stay in the water at all times.
•
The ADCP must be mounted deep enough so that turbulence caused by its movement through
the water does not allow air bubbles to be attached to the transducer faces.
•
Avoid mounting the ADCP near motors and thrusters. They cause air bubbles and will cause bias
to the internal compass.
•
Avoid mountings that will cause the ADCP to see severe accelerations.

Routing Cables
The optional External Battery cable connects to the Sentinel V. Teledyne RD Instruments delivers the cable with both connectors attached. Use care when routing this cable through bulkheads, deck plates, cable
runs and watertight spaces. Make allowances in cable length and engineering design plans for cable routing. When necessary, use strain reliefs on the cables. Route the cable so:
•
Install cables with the connectors attached.
•
It does not have kinks or sharp bends. Do not exceed a bend radius of 75 mm (3 in.).
•
The cable can easily be replaced it if it fails.
•
Protect the cable with abrasion resistant sleeving if zip-ties are used to secure it to structures (see
Figure 32 and Figure 33). Secure the cables to the mounting structure in such a way that the cables do not move or vibrate.
•
Secure all cables to the mounting structure in such a manor so that no forces are exerted on any
connector. Secure the cable as close to the connector as possible without causing any stress to the
connector.
Figure 32.
Do not use Zip-Ties Directly on Cables
When attaching the Sentinel V ADCP cables to the mount, do not zip-tie the cables directly to
the structure. Zip-ties slowly cut through the cable’s outer jacket and cause leaks.
Page 61
June 2013
Sentinel V Operation Manual
Notice the design of the clamps used
to secure the battery housings. See
Mounting the Instrument for clamp
designs.
Always protect the cable when attaching
it to structures. Use an abrasion resistant
sleeving where a zip-tie is used to protect
the cable.

Inspecting the ADCP
Inspect the Sentinel V ADCP to spot problems before and after each deployment:
•
Thoroughly clean the exterior of the ADCP after retrieval. See Removing Biofouling for details.
After a deployment, systems need to be cleaned thoroughly before the touch sensor will work.
•
Check the urethane coating on the transducer faces for dents, chipping, peeling, urethane
shrinkage, hairline cracks and damage that may affect watertight integrity or transducer operation (see Figure 37).
The urethane coating is important to Sentinel V ADCP watertight integrity. Mishandling,
chemicals, abrasive cleaners and excessive depth pressures can damage the transducer
ceramics or urethane coating. Repair of the transducer faces should only be done by TRDI.
•
Check the I/O connector(s) for cracks or bent pins (see Figure 38).
Repair of the connectors should only be done by TRDI.
The connector is made of rubber and as a general maintenance item TRDI recommends that
the connector be replaced every five years or whenever visible signs of wear or corrosion
appear.
•
Check the cable connectors for cracks or bent pins. Inspect the full length of the cable for cuts,
nicks in the insulation and exposed conductors.
•
Check all bolts, washers and split washers for signs of corrosion. Replace if needed.

Disassembly and Assembly Procedures
This section explains how to remove and replace the end-cap or transducer head to gain access to the Sentinel V electronics, batteries and digital recorder.
Disassembling the Sentinel V
If the ADCP was just recovered from a deployment, use caution when removing the end-cap or transducer
head. If the system leaked, water may be inside the housing and under pressure. To avoid any possible
injury always loosen the four bolts to allow any internal pressure to be vented from the system.
CAUTION
Contents May be
Under Pressure.
Refer to Operator’s
Manual Prior to
Servicing.
90Z-6038-00
Caution label on End-Cap
Wear safety glasses and keep head and body clear of the end-cap while opening. Any system
that was deployed may have pressure inside the housing.
Removing the End-Cap
To remove the end-cap:
1.
Dry the outside of the Sentinel V ADCP.
2. Disconnect the I/O cable and install the dummy plug (for systems with an end-cap connector).
3. Lay the Sentinel V ADCP on its side on a soft pad.
4. Inspect the end cap bolts for any signs of damage such as bending, stretched bolts, crushed or deformed housing captive nuts, etc. These signs may indicate that there is internal pressure inside
the system.
5. Using a 4mm Hex Key, loosen each of the M5 captured bolts (counterclockwise) until the O-ring
seal is released.
6. Allow the system the opportunity to vent while the bolts are loose.
To avoid any possible injury ALWAYS loosen the four end-cap bolts to allow any internal
pressure to be vented from the system.
7. Once any possible over-pressure has been released, completely loosen the four M5 retaining bolts.
The end-cap hardware will stay attached to the end-cap.
A lanyard connects the end-cap to the housing. This protects the internal I/O cable from
being pulled too far away from the Sentinel V ADCP.
8. Carefully lift the end-cap away from the housing. Observe how the internal I/O cable is coiled inside the housing. It must be coiled it the same way when replacing the end-cap.
9. Let the end-cap hang from the lanyard to the side of the ADCP. The lanyard protects the internal
I/O cable from being pulled too far away from the Sentinel V ADCP.
Page 68
Sentinel V Operation Manual
June 2013
Removing the Transducer Head Assembly
Normal maintenance does not require removing the transducer head. Use the following
procedures only if directed to do so by TRDI Field Service personnel.
Sentinel V ADCPs contain Electro Static Sensitive Devices. Take accepted ESD prevention
measures before opening the transducer head.
If the transducer assembly is removed, replace both the desiccant and O-ring.
For access to the Sentinel V internal battery, remove the end-cap assembly (see End-Cap
Removal Procedures).
To remove the transducer assembly from the housing:
1.
Dry the outside of the Sentinel V ADCP.
2. Disconnect the I/O cable and install the dummy plug (for systems with an end-cap connector).
3. Lay the Sentinel V ADCP on its side on a soft pad.
4. Inspect the transducer bolts for any signs of damage such as bending, stretched bolts, crushed or
deformed housing captive nuts, etc. These signs may indicate that there is internal pressure inside
the system.
5. Using a 4mm hex key, loosen each of the M5 captured bolts (counterclockwise) until the O-ring
seal is released.
6. Allow the system the opportunity to vent while the bolts are loose.
To avoid any possible injury ALWAYS loosen the four end-cap bolts to allow any internal
pressure to be vented from the system.
7. Once any possible over-pressure has been released, completely loosen the four M5 retaining bolts.
The transducer hardware will stay attached to the transducer assembly.
8. With an ESD ground-strap on, carefully lift the transducer assembly straight up and away from
the housing until the internal I/O cable connector jack is accessible.
Only lift the transducer assembly enough so it can be disconnected the internal I/O cable.
There is no lanyard on the transducer side to protect the internal cable from being
damaged.
9. Gently pull the internal I/O cable connector to release it from the jack. Set the transducer head assembly (transducer face down) on a soft pad.

Reassembling the Sentinel V
To replace the end-cap or transducer head, proceed as follows. Use the Parts Location Drawings for parts
identification.
Replacing the End-Cap
To replace the end-cap:
1.
Stand the Sentinel V ADCP on its transducer face on a soft pad.
2. Clean the mating surfaces of the end-cap and housing with a lint-free cloth.
3. Inspect, clean and lubricate the O-ring on the housing (see Replacing the O-ring). Ensure that the
O-ring is firmly pressed into the groove.
TRDI recommends using a new end-cap O-ring each time the ADCP is opened.
4. Replace the desiccant (see Replacing the Desiccant).
5. Check the internal I/O connectors are connected.
6. Place the end-cap on the housing, aligning the mating holes and the alignment mark embossed on
the end-cap with the alignment mark embossed on the housing. When mating the end-cap with
the housing flange, try to apply equal pressure to all parts of the O-rings. Make sure the O-ring
remains in its retaining groove. As the end-cap is placed on the housing, check the cables are
coiled around the inside of the housing and do not become pinched.
Check that no wires or any other object is pinched between the end-cap and the housing. If
the O-ring is not properly installed or if a wire or other object is pinched, the Sentinel V
ADCP will flood.
Figure 39.
Replacing the End-Cap
If the Sentinel V ADCP uses an internal battery pack, the rubber bumpers on the end-cap hold
the battery in place. Apply a bit of pressure to the end-cap to fully seat it as the end-cap
hardware is tightened.
7. Check the housing captive nuts are not stripped or worn. Replace as necessary (see Replacing the
Captive nuts). Captive nuts snap into place with the small bump facing the housing.
Page 70
Sentinel V Operation Manual
June 2013
8. Examine the end-cap assembly bolts and washers for corrosion; replace if necessary.
Figure 40.
End-Cap Mounting Hardware
9. Install all four sets of hardware until “finger-tight.”
10. Tighten the bolts in small increments in a “cross” pattern until the split washer begins to flatten
out and then use a torque wrench to tighten the bolts to the recommended torque value of 1.7 Nm
(15 Pound-Force Inch).
Apply equal pressure to the O-ring as the bolts are tightened. If one bolt is tightened more
than the others, the O-ring can become pinched or torn. A damaged O-ring will cause the
system to flood.
Do not over tighten the bolts that hold the transducer, housing and end cap together. If the
bolts are over-tightened, the plastic housing can crack or break. On the other hand, leaving
the bolts too loose can cause the system to flood. Tighten the hardware to 1.7 Nm (15 PoundForce Inch).
Replacing the Transducer Head Assembly
To replace the transducer head assembly:
1.
Stand the Sentinel V ADCP on its end-cap on a soft pad.
2. Inspect, clean and lubricate the O-ring on the housing (see Replacing the O-ring). Ensure that the
O-ring is firmly pressed into the groove.
TRDI recommends using a new transducer head O-ring whenever the ADCP is opened.
3. Replace the desiccant (see Replacing the Desiccant). Ensure that the desiccant will not press on
the electronics.
4. Reconnect the internal I/O connector.
5. Gently lower the transducer head/electronics assembly into the housing, aligning the mating
holes and the alignment mark embossed on the transducer with the alignment mark embossed on
the housing. When mating the housing with the transducer head flange try to apply equal pressure
to all parts of the O-ring. Make sure the face O-ring remains in the retaining groove.
Check that no wires or any other object is pinched between the transducer head and the
housing. If the O-ring is not in the groove or if a wire or other object is pinched, the Sentinel V
ADCP will flood.

Apply equal pressure to the O-ring as the bolts are tightened. If one bolt is tightened more
than the others, the O-ring can become pinched or torn. A damaged O-ring will cause the
system to flood.
Do not over tighten the bolts that hold the transducer, housing and end cap together. If the
bolts are over-tightened, the plastic housing can crack or break. On the other hand, leaving
the bolts too loose can cause the system to flood. Tighten the hardware to 1.7 Nm (15 PoundForce Inch).
Replacing the Sentinel V Battery
One of the most often preformed maintenance tasks is battery replacement. The Sentinel V Series ADCP
uses battery packs or individual D-cell batteries to provide power. The housing will be different lengths
depending on the type of batteries used (see Outline Installation Drawings for dimensions and weights).
When the capacity of a battery pack is 50% used, the voltage falls to approximately 14 volts. However,
keep in mind that this voltage is not an accurate predictor of remaining capacity. Batteries should be replaced when the voltage falls below 11 VDC.
Do not leave the battery pack inside the Sentinel V for extended periods. The battery may leak,
causing damage to the electronics.
Sentinel V battery packs are shipped inside the system but not connected. Connect the battery
and seal the Sentinel V before deployment.
Sentinel V with D-cells are shipped without batteries inside the system. Install the batteries and
seal the Sentinel V before deployment.
Battery replacement induces both single and double cycle compass errors. The compass
should be aligned after replacing the battery pack.
Replacing the Battery Pack
To replace the battery pack:
1.
Remove the end-cap (see Removing the End-Cap).
2. Disconnect the black/red battery cable.
3. Place the ADCP on its end on a table/floor and lift the battery pack out of the housing by the battery handle. Do not pull out the battery using the battery cable.
Never pull on the black/red battery pack power cable to remove the battery pack. The cable
will break and may cause the battery pack to short.
Do not drop the battery pack.
Page 72
Sentinel V Operation Manual
June 2013
Use the battery handle to lift out the battery. Optionally, tip the ADCP on its side to slide the
battery pack out.
4. Slide in the new battery pack. Make sure the I/O cable is not pinched by the battery pack.
5. Connect the battery cable.
6. Replace the desiccant (see Replacing the Desiccant).
7. Install the end-cap (see End-cap Replacement).
8. Use the Maintenance panel to set the date the battery was replaced.
9. Align the compass (see Compass Calibration).
Figure 41.

Ensure that proper polarity is observed when installing batteries.
Do not mix old and new batteries.
Do not mix alkaline with non-alkaline batteries.
Do not use damaged batteries.
Do not mix batteries of different brands.
Do not use expired batteries.
Do not leave the batteries inside the Sentinel V for extended periods. The batteries may leak,
causing damage to the electronics.
Store the batteries in a cool, dry location (0 to 21 degrees C).
To replace the D-cell batteries:
1.
Remove the end-cap (see Removing the End-Cap).
2. Remove the battery cover plate by loosening the knob (rotate counterclockwise).
3. Slide out the used batteries.
4. Slide in the new batteries starting with the three batteries in the center with the negative side up.
Next place the other three batteries with the negative side up. Place the last six batteries on the
outer edges with the positive side up. See Figure 42 for battery orientation.

5. Ensure all batteries are fully seated by pushing them all the way down into the battery cavity.
6. Position the cover plate over the batteries.
7. Tighten the knob firmly to hold the batteries in place.
8. Replace the desiccant (see Replacing the Desiccant).
9. Install the end-cap (see Replacing the End-cap). As the end-cap is placed on the housing, check
the cables lay flat and do not become pinched.
Check that no wires or any other object is pinched between the End-Cap and the housing. If
the O-ring is not in the groove or if a wire or other object is pinched, the Sentinel V ADCP will
flood.
10. Use the Maintenance panel to set the date the batteries were replaced.
11. Align the compass (see Calibrating the Compass).

Replacing the External Battery Case Packs
To replace the external battery case battery packs:
1.
Remove the end-cap (see Removing the End-Cap).
2. Disconnect the black/red battery cable on the top battery pack.
3. Tip the external battery case on its side to slide out both used battery packs and the rubber pad.
Do not pull out the batteries using the battery cables.
Never pull on the black/red battery pack power cable to remove the battery packs. The cable
will break and may cause the battery pack to short.
Tip the external battery on its side to slide out the used battery packs.
4. Disconnect the black/red battery cable on the bottom battery pack.
5. Connect the battery cable to the bottom battery pack and slide it into the case. The battery pack
cable of the bottom battery pack faces the bottom of the housing.
6. Slide in the rubber cushion on top of the bottom battery pack.
7. Slide in a second battery pack and connect the battery cable. Make sure the cable is not pinched
by the battery pack.
8. Connect the battery cable to the end-cap connector.
9. Replace the desiccant (see Replacing the Desiccant).
10. Install the end-cap (see End-cap Replacement).
11. Use the Maintenance panel to set the date the battery was replaced.

Calibrating the Compass
The compass calibration for the Sentinel V can be conceptualized as the Sentinel V inside a sphere with
twelve equally spaced points located on the sphere. The twelve points are the data collected during the
compass calibration to orient the compass in different positions relative to the earth’s magnetic field. Each
of the twelve calibration points has a large impact on defining the sphere correctly. The calibration score
(Table 3) is a measure of how well the measured calibration points combine to represent a uniform and
complete sphere.
Figure 44.
Calibrating the Compass
Be aware of the following items:
•
The optimal angle of tilt during calibration is around 50 degrees. Less tilt during calibration is
acceptable if the Sentinel V is not expected to be exposed to much tilt while deployed. This will
be reflected in the z-coverage score.
•
The Sentinel V cannot be adequately calibrated without tilting the system during the compass
calibration. A single plane calibration is not advised.
•
The precision of the tilt angle or heading during calibration are not critical. Tilts and headings
can be off by 10 degrees or more for any step. “By hand” and “by eye” calibrations are possible (a
calibration fixture is not required).
•
The Sentinel V should be calibrated in the same orientation (beams-up/beams-down) as it will
be deployed. Failure to do so will cause a 2 to 4 degrees RMS error on the compass reading
which is outside of the specified heading accuracy for the Sentinel V.
•
Calibration data points can be taken out-of-order if desired.
•
The Sentinel V compass should be calibrated while mounted to the system or mounting structure
whenever possible. The compass can negate hard and soft iron errors, but only if they are accounted for in the calibration.
Page 76
Sentinel V Operation Manual
June 2013
•
Results from the compass calibration are not stored inside the system or in any file.
•
The Maintenance log will indicate that the compass calibration has been completed even if the
compass calibration resulted in a failed condition.
•
If the compass calibration results in a “fail” condition, ReadyV will automatically reject it and restore the factory calibration.
•
The Sentinel V compass should be calibrated after all battery changes.
•
Compass calibration should be performed free from ambient magnetic fields. Nearby steel, iron,
magnets, and other magnetic fields will degrade the calibration and accuracy, and will provide a
bad calibration score. The exception to this rule is if the system is purposely being calibrated
while mounted to a structure or system, and that structure or system is being rotated / manipulated along with the Sentinel V during calibration.
•
The Sentinel V checks for stability before it takes a calibration point. It should be held still in
each position until the point is taken.
•
Protect the Sentinel V surfaces from contact or abrasion during calibration.
To calibrate the compass:
1.
Place the Sentinel V ADCP as far away from metal objects as possible. Use a soft pad to protect the
ADCP during calibration.
Place the ADCP in the same orientation as it will be deployed.
2. Connect to the Sentinel V ADCP.
3. Use the Maintenance panel to start the compass calibration.
4. Orientate the ADCP so that beam 1 points at 0 degrees and tilt the ADCP approximately 30 degrees (beam 1 should be higher than beam 2) (see Figure 45). Click the Take sample button.
5. Rotate the ADCP to the positions as prompted, noting that these are not absolute heading directions, but rather relative headings referenced to the initial heading sample.
6. Once the calibration is complete the Sentinel V ADCP provides a calibration score that indicates
the quality of the calibration (see Table 3). If the Calibration Score is 7 or lower, see Troubleshooting a Bad Calibration Score and start the compass calibration over.
7. Click the Close button to exit the compass calibration screen.

Troubleshooting a Low Calibration Score
If the calibration score is low:
•
If the Standard Deviation score is 7 or lower, make sure the area is clear of magnetic materials (steel, iron, magnets, changing magnetic fields). When in doubt, calibrate outside and away
from metal, machines, and electronics.
•
If the X-Y coverage score is 7 or lower, make sure the rotation directions and tilts are followed.
A 30 to 50 degree tilt during calibration is desired. Over-tilting can also lower this score.
•
If the Z coverage score is 7 or lower, it usually means the system was not being tilted enough
during calibration (a score of 1 means the system was not tilted at all).
Restore to Factory Defaults
If the compass calibration fails after repeated attempts, use the Restore to factory defaults button.
This will use the factory calibration of the compass module itself as it was shipped from the vendor, not a
system level calibration at the time of manufacture at TRDI. This calibration will not take into consideration variables such as magnetic fields from batteries or mounting fixtures. The assumption is a factory
calibration may be better than a failed field calibration result.

Replacing the O-Ring
TRDI strongly recommends replacing the O-ring whenever the Sentinel V ADCP is opened. Inspecting
and replacing the O-ring should be done before sealing the ADCP.
There is no need to disconnect the end-cap cables or lanyard to replace the O-ring. The O-ring
is large enough to stretch over the end-cap.
The O-ring sits in a dove-tail groove. This makes it less likely to fall out when the system is
opened. Use the O-ring tool to pry it out of the groove. Never use metal tools as this may
damage the O-ring groove or the housing flange.
The O-ring is size 2-163 for both transducer and end-cap.
To replace the O-ring:
1.
Remove the end-cap or transducer head (see Disassembly and Assembly Procedures).
2. Insert the tip of the O-Ring tool on the inside edge of the groove and gently slide it around the
groove perimeter to lift the O-Ring.
Page 82
Sentinel V Operation Manual
June 2013
Figure 47.
Using the O-Ring Removal Tool
3. Inspect the O-ring. When viewed with an unaided eye, the O-ring must be free of cuts, indentations, abrasions, foreign matter and flow marks. The O-ring must be smooth and uniform in appearance. Defects must be less than 0.1 mm (0.004 in.).
If the O-ring appears compressed from prior use, replace it. Weak or damaged O-rings will
cause the Sentinel V ADCP to flood.
4. Clean and inspect the O-ring groove and the plastic housing flange. Also check the mating surface
on the transducer and end-cap. Be sure they are free of foreign matter, scratches, indentations,
and pitting.
Check the O-ring groove thoroughly. Any foreign matter in the O-ring groove will cause the
Sentinel V ADCP to flood.
5. Lubricate the O-ring with a thin coat of silicone lubricant. Apply the lubricant using latex gloves.
Do not let loose fibers or lint stick to the O-ring. Fibers can provide a leakage path. Slip the O-ring
over the end-cap and press the O-ring into the groove.
Apply a very thin coat of silicone lube on the O-ring. Using too much silicone lube on the Oring can be more harmful than using no O-ring lube at all.
6. Use the Maintenance panel to set the date the O-ring was replaced.

Sentinel V Operation Manual
Filling the Pressure Sensor Cavity with Oil
The pressure sensor cavity needs to be filled with oil before deployment to deal with both trapped air and
long-term reliability of the pressure sensor. Use Dow Corning Q7-9120 Silicone fluid, 12,500 CST oil. This
fluid is supplied with the Sentinel V ADCP in the spare parts kit. The sensor cavity can be filled any time
before system installation; however care should be taken to keep the ADCP from high temperature during
this time. High temperatures may cause the oil to leak.
The pressure sensor cavity is not filled with oil when shipped. This must be done before
deploying the Sentinel V ADCP.
To fill the pressure sensor with oil:
1.
Place the Sentinel V ADCP on its end-cap. Use a soft pad to protect the ADCP.
2. Use a straight-slot screwdriver to remove the three flat-head black nylon M3 screws on the pressure sensor and then lift off the pressure sensor cover.
3. Fill the pressure port cavity to the top with the oil. A plastic bottle with silicone oil (part number
75BK6004-00) is included in the spare parts kit.
Have an absorbent paper towel on hand to clean up any overflow that may occur.
4. Gently clean out the holes in the pressure sensor cover with a needle. If the holes become enlarged
or the cover is corroded, replace the cover. The cover part number is 81D-4000-00.
5. Install the cover slowly, allowing time for the oil to pass through the holes. Tighten the screws
“finger tight”0.2 Nm (1.8 Pound-Force Inch). Do not over tighten as the threads on the plastic
screws may strip. If this happens, replace the screw (spare flat-head black nylon M3 screws are included in the spare parts kit).
Use extreme caution to not touch or put any pressure on the face of the pressure sensor. The
sensor face contains a sensitive membrane that can be easily damaged. If the membrane is
damaged the pressure sensor will fail.
6. Use the Maintenance panel to set the date the oil was filled.
The Pressure sensor cavity should be checked and if needed refilled between deployments.

Zero the Pressure Sensor
Use the Maintenance panel to zero out the pressure sensor at the deployment site. This must be done prior to deploying the Sentinel V ADCP in the water.
1.
Connect and apply power to the system.
2. On the Maintenance panel, click Pressure sensor. This will zero it.
3. Click the Close button. The date and time the pressure sensor was zeroed will be updated.

Cleaning the Thermistor Cover
In order to respond quickly to changes in the water temperature, water must be able to flow over the sensor. Do not block the thermistor cover or paint over it with antifouling paint. Remove any biofouling as
soon as possible.
The thermistor is embedded in the transducer head. The sensor is under a stainless steel cover
that is highly resistant to corrosion.

Replacing the Desiccant
Desiccant is used to dehumidify the housing interior. Desiccant is essential in deployments with plastic
housings. The factory-supplied desiccant lasts a year at specified Sentinel V ADCP deployment depths and
temperatures. Remember that desiccant rapidly absorbs moisture from normal room air. As a minimum,
replace the desiccant whenever the ADCP housing is opened.
Do not open the desiccant bag. Contact with the silica gel can cause nose, throat and skin
irritation.
Do not puncture or tear the desiccant bag. Do not use desiccant bags that are torn or open.
Desiccant bags are shipped in an airtight aluminum bag to ensure maximum effectiveness.
There is a moisture indicator inside the bag. If the moisture indicator is pink, do not use the
desiccant bag until it has been dried. TRDI recommends replacing the desiccant bag just before
the deployment.
The Sentinel V ADCP housing has separate cavities for the battery and electronics. If the endcap is removed, only replace the end-cap desiccant.
To replace the end-cap side desiccant:
1.
Remove the end-cap (see End-Cap Removal Procedures).
2. Remove the new desiccant bag from the airtight aluminum bag.
3. Remove the old desiccant bag and install a new one. Place the desiccant bag between the battery
pack or D-Cell batteries cover plate and the end-cap as shown in Figure 35 and Figure 36. Ensure
that the desiccant will not interfere with other components when the instrument is closed.
4. Install the end-cap (see End-cap Replacement).
5. Use the Maintenance panel to set the date the desiccant was replaced.
Normal maintenance does not require removing the transducer head. If the transducer
assembly is removed, replace both the desiccant and O-ring.
To replace the transducer side desiccant:
1.

Sentinel V Operation Manual
Preventing Biofouling
This section explains how to prevent the buildup of organic sea life (biofouling) on the transducer faces.
Objects deployed within about 100 meters (≈328 feet) of the surface are subject to biofouling, especially in
warm, shallow water. Soft-bodied organisms usually cause no problems, but barnacles can cut through the
urethane transducer face causing failure to the transducer and leakage into the Sentinel V ADCP.
The best-known way to control biofouling is cleaning the Sentinel V ADCP transducer faces often. However, in many cases this is not possible. In that case, coat the entire Sentinel V ADCP with the recommended
antifouling paint. Make sure that the paint is applied in an even coat over the transducer faces.
As originally manufactured, the transducer faces have a smooth surface which makes it
inhospitable for most biofouling to develop. Preserving this smooth surface is an effective way
to prevent heavy bio-growth on the transducer faces. However, if an antifouling coating is
desired on the transducer faces, then the faces must be lightly abraded to allow for the
antifouling coating to adhere. As a rule, the surface must be kept smooth unless an antifouling
coating will be applied.
Most EPA approved anti-fouling paint can be used on the housing and the urethane transducer faces.
Contact the antifouling paint manufacturer for preparation and application procedures for this and other
antifoulant paints. Interlux is one source of antifouling paint. Contacting this company is done with the
knowledge that Teledyne RD Instruments is not recommending them, but only offering this as a source
for the anti-fouling paint.

The following tips are only general recommendations. Always follow the anti-fouling paint manufacturer’s
instructions on how to apply the anti-fouling paint.
1.
Transducer Face Surface Preparation - Lightly abrade the surface using Scotch Brite® to remove
gloss. Thoroughly clean the areas to be painted with soapy water and dry before applying the antifouling paint.
2. Mask as necessary. Do not paint over mounting hardware, thermistor, and pressure sensor.
3. If applying a second coat, allow the first coat to dry. One coat usually lasts one season (3-4
months); two coats might last one year.
4. Be extra careful to apply a smooth, thin coat of paint to the urethane faces.
5. Apply one or two coats of anti-fouling paint at 4-mil per coat.
Do not block the pressure sensor port. The sensor port has several small holes in the center
of the copper disk. During anti-fouling paint application, tape-off the copper disk. Once the
anti-fouling paint has cured, remove the tape.
This means that the sensor port is not fully protected and fouling may build up on the copper
disk and eventually clog the sensor port. However, the sensor port is surrounded by the
antifouling paint and most organisms do not seem to find the copper surface attractive. If it is
logistically possible to periodically inspect/clean the pressure sensor, it is highly
recommended. This tradeoff situation must be analyzed for individual deployments.
Unfortunately, the location of the deployment site usually dictates action in this regard.
Page 90
Sentinel V Operation Manual
June 2013
Removing Biofouling
To remove foreign matter and biofouling:
1.
Remove soft-bodied marine growth or foreign matter with soapy water. Waterless hand cleaners
remove most petroleum-based fouling.
Do not use power scrubbers, abrasive cleansers, scouring pads, high-pressure marine cleaning
systems or brushes stiffer than hand cleaning brushes on the transducer faces. The urethane
coating on the transducer faces could be damaged.
If there is heavy fouling or marine growth, the transducer faces may need a thorough cleaning to
restore acoustic performance. Barnacles do not usually affect Sentinel V ADCP operation, but
TRDI does recommend removal of the barnacles to prevent water leakage through the transducer
face. Lime dissolving liquids such as Lime-Away® break down the shell-like parts. Scrubbing with
a medium stiffness brush usually removes the soft-bodied parts. Do NOT use a brush stiffer than a
hand cleaning brush. Scrubbing, alternated with soaking in Lime-Away®, effectively removes
large barnacles.
If barnacles have entered more than 1.0 to 1.5 mm (0.06 in.) into the transducer face
urethane, the Sentinel V ADCP should be sent to TRDI for repair. If barnacles cannot be
removed without damaging the transducer faces, contact TRDI.
2. Thoroughly clean out any biofouling from the Touch sensor.
3. Rinse with fresh water to remove soap or Lime-Away® residue.
4. Dry the transducer faces with low-pressure compressed air or soft lint-free towels.
Always dry the Sentinel V ADCP before placing it in the storage case to avoid fungus or mold
growth. Do not store the ADCP in wet or damp locations.
Notice how most organisms did not
seem to find the copper surface of the
Pressure Sensor attractive.

Sentinel V Operation Manual
Troubleshooting Communication Issues
If there is a communications issue or no beeps are heard when power is applied:
•
Open the ADCP to check that the internal end-cap cable(s) and battery connector are connected
correctly.
•
While the end-cap is opened and cables connected, place a finger over the wireless sensor. The
LED on the touch sensor board should light.
•
Check the Sentinel V battery pack voltage is above 11 VDC.
•
Ensure that the Sentinel V battery housing is clean and dry.
•
Replace the Sentinel V D-cell battery springs if their integrity is suspect.
•
For systems using the optional External Battery Case, check the I/O cable female connector and
the ADCP male connector for bent pins, dirt, or foreign objects. Verify power is reaching the
ADCP on the cable connector (see Cable Wiring Diagrams).
Troubleshooting Wireless Issues
If there is a communications issue and the beeps are heard when power is applied:
•
Review the Wireless Connection Common Issues section.
•
Check if a red X or yellow triangle (
) appears over the wireless network icon in the status
bar, the computer reports there is no wireless connection, or a message appears saying there are
no wireless networks available. If any of these conditions apply, click the wireless icon and rightclick on the connection and select Connect.
•
Try to disconnect the ADCP by clicking the wireless icon in the status bar and right-clicking on
the connection. Select Disconnect, and then reconnect.
•
Make sure the ADCP is within the wireless range of the computer (typically within 100 feet). Try
moving the ADCP closer to the computer. If there is a wall between the ADCP and the computer,
try placing the ADCP and computer in the same room. Click the wireless icon in the status bar
and check the signal strength by right-clicking on the connection and selecting Status.
Page 94
Sentinel V Operation Manual
June 2013
•
Make sure there are no other devices interfering with the ADCP, such as microwave ovens, cordless phones, or other wireless devices.
•
If the computer uses an external wireless adapter, make sure the adapter is working correctly
and is attached and installed properly.
•
If wireless capability is integrated into the computer, make sure the wireless transmitter is
turned on. This might also turn the wireless network receiver on and off. Many laptops have an
external switch for turning the transmitter on and off. If you aren't sure how to turn it on, check
the information that came with the computer or go to the manufacturer’s website.
•
Try restarting or refreshing the browser if there is a message that the connection has been lost. If
no keys have been pressed for five minutes, the ADCP will disconnect.
•
If the firmware was just updated, the browser must be closed and set up the wireless network
again.
•
If the ADCP does not appear on the list of wireless networks available to connect to, make sure
the ADCP has not timed out. The network is available after power up for two minutes. Placing a
finger over the Touch sensor starts the network again for two minutes. Click on the Refresh
icon ( ) or use the wireless adapter’s interface to search for connections. Once connected, the
network will remain on.
•
Once connected, if no keys are pressed for five minutes, the ADCP will disconnect. After waiting
two more minutes, the ADCP will power down. Use the Touch sensor to restart.
•
Use the Maintenance panel and save the system log, fault log, and app log. Send the files to TRDI
field service. This may aid in TRDI engineers in troubleshooting the instrument.
Use a local drive or network drive that is always accessible when exporting and importing *.plan
files. ReadyV will “remember” the last drive used and if it is not available, may appear to hang.
Troubleshooting a Built-In Test Failure
The built-in tests check the major Sentinel V modules and signal paths. If a built-in test fails, use the following steps to provide the needed information to the Teledyne RDI Field Service group to help reduce
the investigation process (see How to Contact Teledyne RD Instruments).
Repeat the failing test several times rotating the ADCP by 90 degrees each time. By doing so, it may be
determined that the failure is directional. If other magnetic, acoustic, or high current systems are in the
vicinity of the ADCP, if possible, please power down the equipment and or remove the equipment (at least
three meters away) during diagnostic testing; re-run the tests. Use the Maintenance page and save a copy
of the log files.

Using an Ethernet Connection
This is meant to be a work-around for applications that require a board-level Ethernet connection with a
Sentinel V ADCP, or do not allow wireless or touch sensor operation.
Normal maintenance does not require removing the transducer head. Use the following
procedures only if directed to do so by TRDI Field Service personnel.
Sentinel V ADCPs contain Electro Static Sensitive Devices. Take accepted ESD prevention
measures before opening the transducer head.
If the transducer assembly is removed, replace both the desiccant and O-ring.
Never remove the digital recorder SD Card. The digital recorder is located on the top circuit
board. To recover data, the SD card should be left in the ADCP and accessed using ReadyV.
Open the Transducer
To open the transducer:
1.
Follow the directions in Removing the Transducer Head Assembly. Follow all guidelines and
warnings about ESD protection and safety.
2. Lay the transducer on a soft pad in a beams-down orientation.
3. Position the housing in a way so that the internal cable (power and I/O) can reach the cable jack
on the top board. Make sure to secure the housing so that it doesn’t roll.
Connecting to the ADCP
To connect to the ADCP via Ethernet:
1.
Use an Ethernet cable (CAT 5) to connect to the RJ45 jack on the top board (shown in Figure 55
below). Connect the other end of the cable either directly to a computer or to a router network.
Figure 55.
Ethernet Connection
Figure 56.
Power I/O Cable Connection
2. Connect the internal power I/O cable to the jack on the top board (see Figure 56). After power is
applied (long beep), there is a 10 to 15 second delay before the network is available (short beep).
The LAN is available after power up for two minutes.
Page 98
Sentinel V Operation Manual
June 2013
Step 3 must be completed in two minutes to connect to the ADCP. After two minutes, the
ADCP’s LAN will turn off. In the event that the ADCP’s LAN turns off before the connection is
complete, simply start from step 2 again.
3. Open a browser on the laptop (Internet Explorer®, FireFox®, Google Chrome®, or other browser).
•
If you have a direct Ethernet connection to the ADCP (laptop to ADCP) enter the ADCP’s IP
address 192.168.0.2 into the address bar or enter http://SVnnnnn.adcp (where nnnnn is
the five or six character Sentinel V serial number shown on the product label).
•
If you are connected to the ADCP through a network, enter SVnnnnn only (do not include
the “.adcp” portion). Note that the IP address 192.168.0.2 may not work as IP addresses may
be assigned by the network.
The address is not case sensitive - enter SVnnnnn or svnnnnn.
4. The ReadyV Home panel opens. It can take up to 30 seconds for the Home panel to display.
Ready V functions and features are the same using this method of connection. See Chapter 2 –
Using ReadyV.
Replacing the Transducer Head Assembly
To replace the transducer head:
1.
Remove the Ethernet cable.
2. Replace the transducer side O-ring and desiccant.
Ensure that the desiccant will not press on the electronics.
3. Follow the directions in Replacing the Transducer Head Assembly.

Shipping the ADCP
This section explains how to ship the Sentinel V ADCP.
Remove all customer-applied coatings or provide certification that the coating is nontoxic if a
Sentinel V ADCP is shipped to TRDI for repair or upgrade. This certification must include the
name of a contact person who is knowledgeable about the coating, the name, manufacturer
of the coating and the appropriate telephone numbers. If the equipment is returned without
meeting these conditions, TRDI has instructed our employees not to handle the equipment
and to leave it in the original shipping container pending certification. If certification cannot
be provided, TRDI will return the equipment or send it to a customer-specified cleaning
facility. All costs associated with customer-applied coatings will be at the customer's expense.
When shipping the Sentinel V ADCP through a Customs facility, be sure to place the unit so identifying
labels are not covered and can be seen easily by the Customs Inspector. Failure to do so could delay transit
time.
TRDI strongly recommends using the original shipping crate whenever transporting the
Sentinel V ADCP.
Use the original shipping crate whenever possible. If the original packaging material is unavailable or unserviceable, additional material is available through TRDI.
For repackaging with commercially available materials:
1.
Use a strong shipping container made out of wood or plastic.
2. Install a layer of shock-absorbing static-shielding material, 70-mm to 100-mm thick, around all
sides of the instrument to firmly cushion and prevent movement inside the container.
3. Seal the shipping container securely.
4. Mark the container FRAGILE to ensure careful handing.
5. In any correspondence, refer to the Sentinel V ADCP by model and serial number.

Do not deploy the system with batteries that are older than the Deploy By date. It should be
noted, that while a battery pack will not be dead after the Deploy By date, the actual
performance of the battery is in doubt, and may not have sufficient capacity for the
deployment.
Sentinel V battery packs have three dates on them:
Manufacture Date is the date the battery was built and final tested.
TRDI Ship by Date provides the maximum duration that the battery will remain on TRDI’s
shelves before shipping and is 12 months after the manufacture date.
Deploy By Date provides the last date when the battery should be used to start a deployment
and is 24 months from the manufacture date.

Date of Manufacture
China RoHS requires that all Electrical and Electronic Products are marked with a Date of Manufacture.
This is the starting point for the Environmental Friendly Use Period, described below.
Environmental Friendly Use Period (EFUP)
Per SJ/T 11364-2006 – Product Marking, the EFUP is defined as the time in years in which hazardous/toxic substances within Electrical and Electronic Products (EIP) will not, under normal operating
conditions, leak out of the Product, or the Product will not change in such a way as to cause severe environmental pollution, injury to health, or great damage to property. TRDI has determined the Environmental Friendly Use Period shall be Ten (10) years.
The purpose of the marking is to assist in determining the restricted substance content, recyclability, and
environmental protection use period of our covered products, as required in Chinese law, and does not
reflect in any way the safety, quality, or warranty associated with these TRDI products.
Some homogenous substance within the EIP contains toxic or hazardous substances or elements
above the requirements listed in SJ/T 11363-2006. These substances are identified in Table 17.
WEEE
The mark shown to the left is in compliance with the Waste Electrical and Electronic Equipment
Directive 2002/96/EC (WEEE).
This symbol indicates the requirement NOT to dispose the equipment as unsorted municipal waste,
but use the return and collection systems according to local law or return the unit to one of the TRDI
facilities below.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
Page 138
Sentinel V Operation Manual
June 2013
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that
whole or in part contains or is
part thereof, to be licensed as
parties under the terms of this
you distribute or publish, that in
derived from the Program or any
a whole at no charge to all third
License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
Page 139
June 2013
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
Page 140
Sentinel V Operation Manual
Sentinel V Operation Manual
June 2013
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
Page 141
June 2013
Sentinel V Operation Manual
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the
to attach them to the start of each source file
convey the exclusion of warranty; and each file
the "copyright" line and a pointer to where the
program. It is safest
to most effectively
should have at least
full notice is found.

Copyright (C)  
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:

The licenses for most software are designed to take away your

Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
Page 143

introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
Page 144
Sentinel V Operation Manual
Sentinel V Operation Manual
June 2013
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
Page 145
June 2013
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.

6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
Page 147
June 2013
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.

13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.

Copyright (C)  
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of

MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301
USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
