2.2 Use and Care
The Trimble R7 GPS receiver can withstand the rough treatment that typically occurs
in the field. However, the receiver is a high-precision electronic instrument and should
be treated with reasonable care.
CWARNING – Operating or storing the receiver outside the specified temperature range
can damage it. For more information, see Physical specifications, page 56.
High-power signals from a nearby radio or radar transmitter can overwhelm the
receiver circuits. This does not harm the instrument, but it can prevent the receiver
electronics from functioning correctly. Avoid using the receiver within 400 meters of
powerful radar, television, or other transmitters. Low-power transmitters such as those
used in cellphones and two-way radios normally do not interfere with receiver
operations.
For more information, contact your local Trimble distributor.

2.3 COCOM Limits
The U.S. Department of Commerce requires that all exportable GPS products contain
performance limitations so that they cannot be used in a manner that could threaten
the security of the United States. The following limitations are implemented on the
Trimble R7 GPS receiver.
Immediate access to satellite measurements and navigation results is disabled when
the receiver’s velocity is computed to be greater than 1000 knots, or its altitude is
computed to be above 18,000 meters. The receiver continuously resets until the
COCOM situation is cleared.

Figure 3.6 Postprocessed setup
Note – Instead of hanging the receiver on the tripod, you can place the receiver in its base
case. Run the antenna cable out of the portal in the side of the base case to the antenna so
that the case can stay closed while the receiver is running.
3.1 Pole-mounted setup
To mount the Trimble R7 GPS receiver on a pole, you need to do the following:
1. Mount the eRTK™ Range Pole antenna (RPA).
2. Mount the receiver.
3. Mount the Trimble controller.
This section provides detailed instructions on each of these three steps.
Mounting the range pole antenna (RPA)
To mount the RPA on the pole:
1. Install the RPA bracket 7.5 cm (3") from the pole top by placing the two pieces
together and securing with screws. If you are using a 1" diameter pole, place the
bracket inserts inside the bracket before securing.
Note – Instead of the RPA, you can use a quarter-wave whip (“rubber duck”) antenna
attached directly to the receiver.

3.1 Other system components
This section describes optional components that you can use with the Trimble R7 GPS
receiver.
31.1 Radios
Radios are the most common data link for Real-Time Kinematic (RTK) surveying. The
Trimble R7 GPS receiver is available with an optional internal radio in the 450 MHz
UHF band. You can also connect an external radio to Port 3, whether or not the
internal radio is installed.
The Trimble R7 GPS receiver supports the following Trimble base radios when using
the internal receiver radio:
•TRIMMARK™ 3
•TRIMMARK IIe
•TRIMTALK™ 450S
•SiteNet™ 450
•Trimble R6 GPS and Trimble R8 GNSS receiver internal transmitter (base)
•Trimble HPB450 radio-modem
Internal radio setup
You can configure the Trimble R7 GPS receiver optional internal radio using any of the
following:
•the GPS Configurator software
•the WinFlash utility
•the Trimble Survey Controller software
For more information, refer to the GPS Configurator Help, the WinFlash Help, or the
Trimble Survey Controller User Guide.
By default, the internal UHF radio has only a few frequencies installed. Use the
WinFlash utility to configure additional frequencies. For more information, see Adding
frequencies for the 450 MHz internal radio, page 52.
External radio setup
To use an external radio with the Trimble R7 GPS receiver, you need an external power
source for the radio.
Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 23
Setting up the Receiver 3
Trimble R7 GPS Receiver Operation
To set up a Trimble R7 GPS receiver using an external radio:
1. Connect one end of the yellow GPS antenna cable to the yellow TNC port on the
receiver.
2. Connect the other end of the GPS antenna cable to a Zephyr or Zephyr Geodetic
antenna.

Figure 3.12 shows a TRIMMARK 3 radio connected to a Trimble R7 GPS receiver.
Figure 3.12 Connecting an external radio
5. Connect an external power source to Port 2 on the receiver.
Note – External rover radios must have their own power source because the
internal Lithium-ion batteries do not supply enough voltage. Alternatively, supply
external power to Port 2 of the receiver, and enable power out on Port 3.
Base radios must have their own power source because of their high power
consumption.
Alternatively, you can apply external power directly to the radio, if it supports it.
You can use a 10 Ah battery, a 6 Ah battery, or camcorder batteries. The choice
of power supply depends on the application, and whether you are using the
radio as a reference or rover radio. For more information about the power
capabilities of the Trimble R7 GPS receiver, see Batteries and power, page 32.
6. Configure the external radio using Trimble Survey Controller software.
Alternatively, you can configure a TRIMMARK 3 radio using the WinFlash utility
or the configuration software supplied with the radio.

appropriate Help.
7. Set up any other equipment as required, depending on whether you are using
the radio as a reference or a rover radio.
30.1 Cellular modems
You can use a cellular modem instead of a radio as your data communications link.
Cellular modems and other radio links can be used to extend the limits of your surveys.
To connect a cellular modem to a Trimble R7 GPS receiver, you need the following:
•A Trimble R7 GPS receiver
•A custom-designed cellular modem, or a cellphone that can transmit and
receive data
•Serial (cellphone to DB9) cable (supplied with the cellular modem or phone)
•Trimble DB9 to 0-shell Lemo cable
Note – This cable is suitable only if flow control can be disabled on the cellular modem. If
the cellular modem does not support this functionality, a special cable is required. For
more information, refer to the document Using Cellular and CDPD Modems for RTK,
which is available from your local Trimble Distributor.
Figure 3.13 shows the components required to connect a cellphone to a Trimble R7
GPS receiver.

30.2 Antennas
The Trimble R7 GPS receiver should normally be used with a Zephyr or Zephyr
Geodetic antenna, which have been designed specifically for use with this receiver.
Use Figure 3.14 as a guide for measuring the height of the Zephyr and Zephyr Geodetic
antennas. The Zephyr antenna is designed to be measured to the top of the notch. The
Zephyr Geodetic (shown) has been designed to be measured to the bottom of the
notch.
Figure 3.14 Measuring antenna height
Older models of antennas, such as the Choke Ring or Micro-Centered™ L1/L2
antennas, need more power to operate than the Zephyr models. To configure the
receiver to output more power on the antenna port, select the correct antenna type in
GPS Configurator, or through the Trimble controller. For information on how to do
this, contact your local Trimble Service Provider.
30.3 CompactFlash cards
The Trimble R7 GPS receiver logs data internally on a CompactFlash card. However, it
only support the Type I CompactFlash card. Trimble recommends that you use an
industrial-rated CompactFlash card, as commercial cards have a limited operating
temperature range.
Before logging data to a CompactFlash card, format the card to ensure the integrity of
the file system. To format the card, insert it in the receiver and then hold down the
power button for 30 seconds.
Note – Make sure that you format your CompactFlash card in the receiver. This prevents
data on the card from being corrupted if the card is removed while data is being logged.

seconds, the receiver is reset to its factory defaults, and any ephemeris file is deleted.
After 30 seconds, any files stored on the card are deleted and the CompactFlash card is
reformatted.
Note – When you use [P] to format the CompactFlash card, a quick format is performed. A
quick format reformats the card for use with the Trimble R7 GPS receiver and deletes all
data on the card. A full format checks the card for errors or bad sectors, and is only
necessary if the card is corrupted. To perform a full format, use the GPS Configurator
software. For more information, see The GPS Configurator software, page 50.
4.8 Batteries and power
CWARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery
can cause an explosion or fire, and can result in personal injury and/or property damage.
To prevent injury or damage:
– Do not use or charge the battery if it appears to be damaged. Signs of damage include,
but are not limited to, discoloration, warping, and leaking battery fluid.
– Do not expose the battery to fire, high temperature, or direct sunlight.
– Do not immerse the battery in water.
– Do not use or store the battery inside a vehicle during hot weather.
– Do not drop or puncture the battery.
– Do not open the battery or short-circuit its contacts.
Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 33
General Operation 4
Trimble R7 GPS Receiver Operation
The Trimble R7 GPS receiver can be powered either by its two internal batteries or by
an external power source connected to Port 2 or Port 3. The charge provided by the
internal batteries depends on the type of survey and operating conditions. Typically,
one battery provides about 3.5 hours of power during an RTK survey using the internal
radio, and about 5 hours during a survey without the internal radio.
The external power source is always used in preference to the internal batteries. When
there is no external power source connected, or if the external power supply fails, the
internal batteries are used. The internal batteries are drained in turn, and the receiver
automatically switches to the full battery when the first battery is drained.
If no external power is supplied and both internal batteries are drained, none of the
data that you have logged is lost. When internal or external power is restored, the
receiver restarts in the same state as when power was lost. For example, if the receiver
was logging data, the data file is not corrupted, and when power is restored the
receiver resumes logging with the same settings as before.
The power supply that comes with the Trimble R7 GPS receiver charges the internal
batteries while they are still in the receiver. To do this, connect the power supply to the
power/serial data cable, connect the cable to Port 2 on the receiver and then connect
the power supply to an AC power source, as shown in Figure 4.2.
Figure 4.2 Charging the batteries
The two internal batteries take approximately eight hours to charge. They are charged
individually, so each battery takes approximately four hours to charge. The internal
batteries start charging whenever an external power supply of greater than 15 V is
detected.

CWARNING – Avoid contact with the rechargeable Lithium-ion battery if it appears to be
leaking. Battery fluid is corrosive, and contact with it can result in personal injury and/or
property damage.
To prevent injury or damage:
– If the battery leaks, avoid contact with the battery fluid.
– If battery fluid gets into your eyes, immediately rinse your eyes with clean water and
seek medical attention. Do not rub your eyes!
– If battery fluid gets onto your skin or clothing, immediately use clean water to wash off
the battery fluid.
Each receiver in your system is supplied with two internal Lithium-ion battery packs.
To charge both sets of batteries, connect both receivers to power supplies as shown in
Figure 3.2.
48.1 Battery charging and storage
All battery types discharge over time when they are not being used. Batteries also
discharge faster in colder temperatures. If a Lithium-ion battery is to be stored for long
periods of time, make sure it is fully charged before storing and re-charged at least
every three months.
CWARNING – Charge and use the rechargeable Lithium-ion battery only in strict
accordance with the instructions. Charging or using the battery in unauthorized
equipment can cause an explosion or fire, and can result in personal injury and/or
equipment damage.
To prevent injury or damage:
– Do not charge or use the battery if it appears to be damaged or leaking.
– Charge the Lithium-ion battery only in a Trimble product that is specified to charge it.
Be sure to follow all instructions that are provided with the battery charger.
– Discontinue charging a battery that gives off extreme heat or a burning odor.
– Use the battery only in Trimble equipment that is specified to use it.
– Use the battery only for its intended use and according to the instructions in the product
documentation.
Charging the Lithium-ion battery
The rechargeable Lithium-ion battery is supplied partially charged. Charge the battery
completely before using it for the first time. If the battery has been stored for longer
than six months, charge it before use.
To protect the battery from deep discharge (5 V or less), the Trimble R7 GPS receiver is
designed to switch batteries or cease drawing power when the battery pack discharges
to 5.9 V.
A battery that has reached the deep discharge level cannot be recharged and must be
replaced. The following recommendations provide optimal performance and extend
the life of your batteries:
•Fully charge all new batteries before use.
Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 35
General Operation 4
Trimble R7 GPS Receiver Operation
•Do not allow the batteries to discharge below 5 volts.
•Keep all batteries on continuous charge when not in use. Batteries may be kept
on charge indefinitely without damage to the receiver or batteries.
•Do not store batteries in the receiver or external charger unless power is applied.
•If you must store the batteries, fully charge them before storing and then
recharge them at least every three months.
Disposing of the rechargeable Lithium-ion battery
Discharge the Lithium-ion battery before disposing of it. When disposing of the
battery, be sure to do so in an environmentally sensitive manner. Adhere to any local
and national regulations concerning battery disposal or recycling.
48.2 Operating with the TSCe controller
If the receiver is being powered by its internal batteries, it does not supply power to the
TSCe controller when they are connected. However, the TSCe controller batteries and
the Trimble R7 GPS receiver batteries can be charged at the same time from the same
power supply. To charge both sets of batteries, use two standard power/serial data
cables to connect the TSCe controller and the receiver to a power supply, as shown in
Figure 4.3.

48.3 Power output
If the receiver is being supplied with power from an external source, power is
automatically output on Port 1. The output voltage is approximately 0.5 V less than the
input voltage. Port 1 outputs a maximum voltage of 20 V, even if the input voltage is
higher.
You can use GPS Configurator or Trimble Survey Controller software to enable power
output on Port 3. Port 3 can be enabled for power output regardless of whether power
is supplied internally or externally.
On Port 3, the output voltage is approximately 0.5 V less than the input voltage. For
example, if power is being supplied from the internal Lithium-ion batteries, the
maximum battery voltage is 8.4 V, so the maximum output voltage is 7.9 V.
Note – When you start a survey using the Trimble Survey Controller software, and you are
using an external radio, the software automatically enables power output on Port 3.
48.4 Firmware
A receiver’s firmware is the program inside the receiver that makes the receiver run and
controls the hardware. When you need to upgrade the firmware for your Trimble R7
GPS receiver, Trimble recommends that you use the WinFlash utility. For more
information, see The WinFlash utility, page 50.
CWARNING – Upgrading the firmware deletes all application files on the Trimble R7 GPS
receiver.
An alternative method of upgrading your firmware is to copy the .elf file directly to the
CompactFlash card from your computer:
1. Connect the CompactFlash card to your desktop computer.
2. Using Windows Explorer, copy the .elf file from your computer to the
CompactFlash card.
3. Disconnect the CompactFlash card from your computer and insert it into the
receiver.
4. Turn the receiver off.
5. Hold down [D] and press [P].
The receiver starts up in Monitor mode, automatically detects the newer version
of the firmware, and installs it. In Monitor mode, the red SV tracking LED is lit
solidly and the yellow Logging/memory LED flashes slowly.
The upgrade takes about two minutes. Once the upgrade procedure is complete,
the receiver restarts automatically.

application files
QApplication files
The Trimble R7 GPS receiver has no controls for
changing settings. To configure the receiver, use
external software, such as GPS Configurator or
Trimble Survey Controller.
To configure the Trimble R7 GPS receiver, do one
of the following:
•Configure the receiver in real time
•Apply the settings in an application file
This chapter provides a brief overview of each of
these methods, and describes the contents and
use of application files.
5 Configuration
38 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide
Trimble R7 GPS Receiver Operation
5.1 Configuring the receiver in real Time
The GPS Configurator and Trimble Survey Controller software support real-time
configuration of the Trimble R7 GPS receiver.
When you configure the receiver in real time, you use one of these software
applications to specify which settings you want to change. When you apply the
changes, the receiver settings change immediately.
Any changes that you apply to the receiver are reflected in the current application file,
which is always present in the receiver. The current application file always records the
most recent configuration, so if you apply further changes (either in real time or using
an application file) the current file is updated and there is no record of the changes that
you applied originally.
For more information on configuring the receiver in real time, see Chapter 7, Software
Utilities.
5.2 Configuring the receiver using application files
An application file contains information for configuring a receiver. To configure a
receiver using an application file, you need to create the application file, transfer it to
the receiver, and then apply the file settings. The GPS Configurator software does this
for you automatically when you work with configuration files.
For more information on applying application files, see Chapter 7, Software Utilities.
5.3 Application files
An application file is organized into records. Each record stores configuration
information for a particular area of receiver operation. Application files can include the
following records:
•File Storage
•General Controls
•Serial Port Baud/Format
•Reference Position
•Logging Rate
•SV Enable/Disable
•Output Message
•Antenna
•Device Control
•Static/Kinematic
•Input Message
Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 39
Configuration 5
Trimble R7 GPS Receiver Operation
•Timed Activation
An application file does not have to contain all of these records. When you apply an
application file, any option that is not included in the records in the file remains at its
current setting. For example, if you apply an application file that only specifies the
elevation mask to use, all other settings remain as they were before the application file
was applied.
You can store up to twenty different application files in battery-backed memory on the
receiver. You can apply an application file’s settings at the time it is transferred to the
receiver, or at any time afterwards.
53.1 Special application files
The Trimble R7 GPS receiver has three special application files, which control
important aspects of the receiver’s configuration.
Default application file
The default application file (Default.cfg) contains the original receiver configuration,
and cannot be changed. This file configures the receiver after it is reset. To reset the
receiver, hold down [P] for at least 15 seconds, or use the reset option in the GPS
Configurator software.
For more information, see Default settings, page 60.
Although you cannot change or delete the default application file, you can use a power
up application file to override any or all of the default settings.
Current application file
The current application file (Current.cfg) reflects the current receiver configuration.
Whenever you change the receiver’s configuration, either in real time or by applying an
application file, the current file changes to match the new configuration.
You cannot delete the current file or change it directly, but every change to the
receiver’s current configuration is applied to the current file as well.
When you turn off the receiver then turn it on again, all the settings from the current
application file are applied, so you do not lose any changes that you have made. The
only exceptions are the following logging parameters:
•Logging rate

These parameters are always reset to the factory default values whenever the receiver
is switched off.

Power up application file
the power up application file (Power_up.cfg) is optional. if a power up file is present, its
settings are applied whenever the receiver is turned on.
In this file, you can specify that the receiver is reset to defaults before the power up
settings are applied. This ensures that restarting the receiver always results in the same
configuration. This method is useful for defining “default” settings for the receiver that
differ from those in the default file, which cannot be changed.
Alternatively, you can specify that the power up settings are applied immediately after
the current application file’s settings have been applied. Restarting the receiver results
in a configuration that uses your default settings for the options you define in the
power up file, but the current settings for all other options.
By default, there is no power_up application file on the receiver. To use a power up
application file, you must create and save a power_up application file in the GPS
Configurator software. If you save this file to disk, the file is called power_up.cfg. The
extension .cfg is used by convention to identify application files on the office computer.
when you transfer this file to the receiver, the file is saved on the receiver as power_up,
and becomes the new power up file.
The power up file is the only special application file that you can overwrite or delete
from the receiver.
53.2 Timed application files
A timed application file contains a Timed Activation record which specifies when this
file is to be applied. The main use of a timed application file is to automatically start or
stop logging at a predefined time.
The Timed Activation record specifies:
•the UTC date and time when the application file is to be applied for the first
time
•the interval at which the file is to be reapplied
If you do not specify a repeat interval, the settings are applied only once, at the
specified time. If the file specifies a repeat interval, the file’s settings are reapplied at
the specified interval until the file is deactivated.
Note – If the receiver is logging continuously, the current logging takes precedence over any
timed application file stored in the receiver.
Defining timed application files
To send timed application files to a Trimble R7 GPS receiver, set up scheduled survey
sessions in the GPS Configurator software. You can define multiple sessions, each
specifying:
•basic logging parameters (data logging rate, position logging rate, and elevation
mask)
Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 41
Configuration 5
Trimble R7 GPS Receiver Operation
•a starting time
•a duration
When you apply the current settings in the GPS Configurator software, each defined
survey session is sent to the Trimble R7 GPS receiver as a pair of timed application files:
the first includes the logging settings and start time, and the second contains settings
that stop logging at the end time (which is calculated automatically from the duration
you specify).
For more information on scheduled survey sessions, refer to the GPS Configurator
Help.
The receiver can store up to 20 application files, so you can define a maximum of 10
scheduled survey sessions (10 pairs of start/stop timed application files).
Sleep mode
Whenever you press [P] to turn off the Trimble R7 GPS receiver, the receiver checks for
a timed application file that is due to be activated in the future. If one exists, the
receiver goes into Sleep mode instead of turning off.
In Sleep mode, the yellow Logging/Memory LED flashes every three seconds. The
receiver wakes up five minutes before the scheduled activation time, so that it is ready
to begin logging at the scheduled time.
53.3 Applying application files
An application file’s settings do not affect the receiver’s configuration until you apply
the application file. You can do this at the same time that you save the file.
Alternatively, save the file on the computer or in the receiver, then open it later and
apply its settings.
Note – If the application file is a timed file, its settings do not take effect as soon as you
apply the file, but at the time that the file specifies for its activation.
53.4 Storing application files
You can store application files that you create in the GPS Configurator software on the
receiver and on the computer. For example, each file can represent a different user
sharing the same receiver, or a particular mode of operation or survey style. Saving
application files on your computer as well as in your receiver is optional, but it is useful
because:
•it gives you a permanent copy of the settings you have sent to a receiver, for
audit or your own reference.
•you can use the same file to configure multiple receivers identically.
•you can use an existing application file as a template to create other application
files with similar settings.
5 Configuration
42 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide
Trimble R7 GPS Receiver Operation
53.5 Naming application files
The application filename in the office computer and in the receiver is always the same.
This makes it easier to recognize and keep track of your application files.
When you change the name of the application file in the receiver, this changes the
application filename on your computer. When you transfer an application file from the
receiver and save it to the computer, the system renames the file to match the internal
receiver file. However, if you use Windows Explorer, for example, to change the .cfg
filename on the computer, this does not change the internal receiver filename. This
means that the GPS receiver does not recognize the change to the filename on the
computer.

Figure 6.2 Connecting the Trimble R7 GPS receiver to a computer for USB data transfer
Note – When the receiver is connected to a USB port on a computer, it is treated as a
peripheral device of the computer. If the receiver is unplugged or turned off, a warning
message appears on the computer.
6.2 Transferring data
Transfer the data files to the computer using the Trimble Data Transfer utility. You can
run this utility as a standalone program or from within the Trimble Geomatics Office
software. For more information, refer to the Data Transfer Help.
Note – When you connect to a receiver in the Data Transfer utility, you must use a GPS
Receiver (R/5000 Series) device definition. If you use a GPS Receiver (4000 Series) device
definition, the Data Transfer utility cannot establish communication with the receiver.
When transfer is complete, the Data Transfer utility automatically converts the file to
the DAT format. If you are using Data Transfer from within the Trimble Geomatics
Office software, the Check-in dialog appears. For more information, refer to the Trimble
Geomatics Office User Guide.
Note – A file in DAT format is approximately six times the size of the corresponding file in
the Trimble R7 GPS receiver internal format. Before transferring files, make sure that there
is enough space on your computer.

6.3 Transferring files directly from a CompactFlash card
In a Trimble R7 GPS receiver, all data is stored on an internal CompactFlash card.
There are two ways to transfer files between the receiver and the office computer:
•Connect the receiver to the office computer and use the Data Transfer utility to
transfer files.
•Remove the CompactFlash card from the receiver and connect it directly to your
office computer, where it functions like a normal disk drive. Use Windows
Explorer to transfer files.
When you use the Data Transfer utility to transfer data files from the CompactFlash
card while it is still inserted in the receiver, the Data Transfer utility converts the raw
receiver data (.T01) files you select into the Trimble DAT file format.
However, if you connect the CompactFlash card to your computer and then copy or
move files to your computer, it treats the card like any other disk drive, and transfers
the files without converting them. You need to convert these raw receiver files to DAT
format files before you can use them on your office computer.
You can convert receiver data files using a Windows Explorer extension, which is
installed on your computer when you install the Data Transfer utility.
Note – Although this extension is only available if you have the Data Transfer utility
installed, you do not have to run the Data Transfer utility to use it.
To convert a .T01 file on your office computer into the DAT format:
1. On your office computer, open Windows Explorer and navigate to the location
of the .T01 file.
2. Right-click the file, and select Convert to DAT format from the shortcut menu:
Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 47
Transferring Data 6
Trimble R7 GPS Receiver Operation
The DAT File Conversion dialog appears while the file is converted. When the dialog
disappears, the file conversion is complete.
A new file with the same filename but a .dat extension appears in the same folder as
the .T01 file.
6.1 Deleting files in the receiver
You can delete files stored in the receiver at any time. Do one of the following:
•Use the Data Transfer utility in the Trimble Geomatics Office software.
•Use the TSCe controller.
•Turn on the receiver and then hold down [P] for 30 seconds. When you use this
method, all data is deleted, and the CompactFlash card is reformatted.
•Use the GPS Configurator software.
6.2 Supported file types
Table 6.1 shows the file types that you can transfer to or from a Trimble R7 GPS
receiver, and the software or utility that you must use to transfer each file type.
Note – The Trimble R7 GPS receiver supports a maximum of 512 files on the
CompactFlash card. Files stored on the compact flash must be 8.3 format. The Trimble R7
GPS receiver does not support extended file names.

9.2 Resetting to factory defaults
To reset the receiver to its factory defaults, do one of the following:
•On the receiver, press and hold down [P] for 15 seconds.
•In the GPS Configurator software, select Connect to Receiver and then click Reset
receiver in the General tab.
9.3 Examples
The following examples show how the Trimble R7 GPS receiver uses the default
settings and special application files in various situations.
93.1 Default behavior
The factory defaults are applied whenever you start the receiver. If a power up file is
present in the receiver, its settings are applied immediately after the default settings, so
you can use a power up file to define your own set of defaults.
93.2 Power up settings
When you turn the receiver off, any changes that you have made to logging settings are
lost and these settings are returned to the factory defaults. Other settings remain as
defined in the current file. The next time you turn on the receiver, the receiver checks
for a power up file and, if one is present, applies the settings in this file.

93.3 Logging after power loss
If the Trimble R7 GPS receiver loses power unexpectedly, when power is restored the
receiver tries to return to the state it was in immediately before the power loss. The
receiver does not reset itself to defaults or apply any power up settings. If the receiver
was logging when power was lost unexpectedly, it resumes logging when power is
restored.
However, when you turn off the receiver using [P], the receiver behaves as if you pressed
[D] to stop logging before you pressed [P]. In this case, when power is restored normally,
logging does not begin until you start it manually.
93.4 Disabling logging
To disable logging, you can set the receiver’s data logging and position logging rates to
Off. However, if you press [D] while logging is disabled, the receiver will still log data,

93.5 Application files
You can use application files to change the settings in the receiver. Sending an
application file to the receiver does not necessarily apply the file’s settings; you can
apply a file’s settings at any time after sending it to the receiver. You can also define
timed application files. A timed application file contains receiver settings, but also
includes a date and time when it is automatically activated.
If there is a timed application file on the Trimble R7 GPS receiver, the receiver
automatically applies the file’s settings and begins logging (if logging settings are
included in the file) at the specified time. If the receiver is in Sleep mode, it wakes up
five minutes before the start time of the timed application file, and then begins logging,
if required, at the specified start time.

10.4GPS antennas and cables
The antenna that a receiver uses to collect satellite signals is sometimes called a GPS
antenna to distinguish it from a radio antenna. Radio antennas are used for
communication between receivers and external networks or systems.
Note – Older models of antennas, such as Choke Ring or Micro-Centered L1/L2, have
different power requirements. The Trimble R7 GPS receiver can adjust the antenna power
output when you designate the appropriate antenna in the GPS Configurator software. For
more information, see Antennas, page 25.
Connect the receiver to its GPS antenna using the yellow TNC connector. Use a coaxial
cable with a right-angle TNC plug at the antenna end.

Trimble R7 GPS Receiver Operation
11.1Event marker input
Use event marker input to log a precise GPS time tag whenever an externally generated
pulse is received, such as one generated at the time of the shutter closing from a
photogrammetric camera.
The event is triggered when the source pulse voltage transitions between 1.0 V DC and
2.0 V DC in less than 100 nsec. Trimble recommends that you use TTL level inputs. You
can configure the receiver to recognize either a positive (rising) or negative ( falling)
voltage as the leading edge of a pulse. The accuracy of the associated time tag recorded
for an event is determined by the GPS accuracy (typically less than 1 μsec.).
The Trimble R7 GPS receiver records each event in the current data file. This record
includes the port on which the event was received.
111.1 Enabling and configuring event marker input
To enable or configure the event marker input function, you need the GPS
Configurator software.
In real time
You can use the GPS Configurator software to configure a Trimble GPS receiver
connected to your office computer. For more information, see The GPS Configurator
software, page 50, or refer to the GPS Configurator Help.
To enable event marker input:
1. Connect the computer to the Trimble R7 GPS receiver.
2. Press [P] to turn on the receiver.
3. To start the GPS Configurator software, click and then select
Programs /Trimble /GPS Configurator /GPS Configurator. The GPS Configurator
dialog appears and the software automatically connects to the Trimble R7 GPS
receiver.
4. In the General tab, select the Event marker check box.
5. Select the appropriate option, Positive slope or Negative slope, depending on the
type of pulse the external device uses.
6. Click Apply.
The GPS Configurator software sends the new configuration information to the
receiver, and the receiver starts to accept event marker input.
7. Click OK to exit the GPS Configurator software.
The software disconnects from the receiver.

Event Marker Input and 1PPS Output 11
Trimble R7 GPS Receiver Operation
11.11PPS output
The Trimble R7 GPS receiver can output a one pulse per second (1PPS) time strobe
with an associated ASCII time tag output. The pulse is output through port 2 of the
receiver using the event marker/1PPS cable.
111.1 1PPS pulse definition
The leading edge of the pulse coincides with the beginning of each UTC second, as
shown in Figure 11.1. The pulse is driven by an RS-422 driver between nominal levels of
0 V and 4 V. The leading edge is positive, rising from 0 V to 4 V.
Figure 11.1 Time tag relation to 1PPS wave form
The pulse is approximately 8 μsec wide, with rise and fall times of about 100 nsec.
Resolution is approximately 40 nsec, but several external factors limit accuracy to
approximately ±1 μsec:
•Position errors, especially with user-entered reference. Each meter of error can
result in 3 nsec of error in the 1PPS pulse.
•Antenna cable length. Each meter of cable adds a delay of about 2 nsec to
satellite signals, and a corresponding delay in the 1PPS pulse.
111.2 ASCII time tag definition
Each time tag is output about 0.5 second before the corresponding pulse, as shown in
Figure 11.1. Time tags are in ASCII format on a user-selected serial port. The format of
a time tag is:
UTC yy.mm.dd hh:mm:ss ab
Where:
•UTC is fixed text.
•yy.mm.dd is the year, month, and date.
•hh:mm:ss is the hour (on a 24-hour clock), minute, and second. The time is in
UTC, not GPS time.

•a is the position-fix type:
1 = 2D Position Fix for E,N only
2 = 3D Position Fix
3 = Single SV Clock-only fix
4 = Automatic Mode
5 = Reference Station Position
6 = Two-Dimensional with Fixed Clock
7 = Overdetermined solution for Clock-only
•b is the number of satellites being tracked: 1 to 9, “:” ( for 10), “;” ( for 11), or “<”
(for 12).
•Each time tag is terminated by a carriage return, line feed sequence.
A typical printout looks like this:
UTC 93.12.21 20:21:16 56
UTC 93.12.21 20:21:17 56
UTC 93.12.21 20:21:18 56
If the fields “a” and “b” appear as “??”, the time is based on the receiver clock because
the receiver is not tracking satellites. The receiver clock is less accurate than time
readings extracted from satellite signals.
111.3 Enabling and configuring 1PPS output in real time
To enable or configure the 1PPS output function, you need the GPS Configurator
software. You can use the GPS Configurator software to configure a Trimble GPS
receiver connected to your office computer. For more information, see The GPS
Configurator software, page 50, or refer to the GPS Configurator Help.
1. Connect the computer to the Trimble R7 GPS receiver.
2. Turn on the receiver.
3. To start the GPS Configurator software, click and then select
Programs /Trimble /GPS Configurator /GPS Configurator. The GPS Configurator
dialog appears and the software automatically connects to the receiver.
4. Select the Serial outputs tab.
5. Select the 1PPS (Port 2 only) check box.
6. If you want ASCII time tags enabled, select the check box and choose an output
port.
7. Click Apply.
The GPS Configurator software sends the new configuration information to the
receiver, and the receiver starts to generate 1PPS output on Port 2.
8. Click OK to exit the GPS Configurator software.
The software disconnects from the receiver.

12.2Use and care
The receiver can withstand the rough treatment that typically occurs in the field.
However, it is a high-precision electronic instrument and should be treated with
reasonable care.
CWARNING – Operating or storing the receiver outside the specified temperature range
can damage it. For more information, see Chapter 17, Specifications.
High-power signals from a nearby radio or radar transmitter can overwhelm the
receiver circuits. This does not harm the instrument, but it can prevent the receiver
electronics from functioning correctly. Avoid using the receiver within 400 meters of
powerful radar, television, or other transmitters. Low-power transmitters such as those
used in cellphones and two-way radios normally do not interfere with receiver
operations.

12.3COCOM limits
The U.S. Department of Commerce requires that all exportable GPS products contain
performance limitations so that they cannot be used in a manner that could threaten
the security of the United States. The following limitations are implemented on the
Trimble R6 GPS and R8 GNSS receivers.
Immediate access to satellite measurements and navigation results is disabled when
the receiver’s velocity is computed to be greater than 1000 knots, or its altitude is
computed to be above 18,000 meters. The receiver continuously resets until the

any collected GLONASS data. Consider this if you plan to use the Trimble Geomatics
Office software to process the *.dat files because that software does not process GLONASS
data.
If you have the Trimble Business Center software, the *.T01 file that is stored on the receiver
can be directly downloaded. The *.T01 files will contain any collected GLONASS data
because the Trimble Business Center software can process GLONASS data, if you have
purchased that option.
CWARNING – The receiver allows for a maximum of 200 files on the internal memory. The
filenames must be in 8.3 format, otherwise, files copied to the internal memory may cause
data corruption or loss of data when logging.
Data is logged using the current logging settings configured in the receiver. Data files
logged internally are named automatically.
To begin internal logging, you must use a Trimble controller, or the GPS Configurator
software. The receiver does not have an internal clock, so you can only conduct timed
survey sessions if the receiver has a continuous power supply.
When the internal memory is full, the receiver stops logging data, and the
Logging/Memory LED turns off. Existing data files are not overwritten. You can use the
Auto-delete option to override this action and automatically delete the oldest files
when the receiver memory is full. However, you should use this option with caution
because it can lead to data loss.
Approximate storage requirements for different logging rates are shown below. The
values shown are for a one-hour logging session with six satellites visible.
145.2 Logging to a Trimble controller
When the receiver is connected to a Trimble controller, you can log GPS data from the
receiver to the controller, or to a PC card inserted in the controller. When you use a
Trimble controller, you do not use the receiver’s controls. Instead, you use the
controller functions to set logging options, specify filenames, and control when logging
occurs.
Data is stored in job files, which can be transferred to your office computer using the
Trimble Data Transfer utility.
For more information on logging data from a receiver using a Trimble controller, refer
to the user guide for your particular controller.

14.7Batteries and power
CWARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery
can cause an explosion or fire, and can result in personal injury and/or property damage.
To prevent injury or damage:
– Do not use or charge the battery if it appears to be damaged. Signs of damage include,
but are not limited to, discoloration, warping, and leaking battery fluid.
– Do not expose the battery to fire, high temperature, or direct sunlight.
– Do not immerse the battery in water.
– Do not use or store the battery inside a vehicle during hot weather.
– Do not drop or puncture the battery.
– Do not open the battery or short-circuit its contacts.
The receiver can be powered by its internal battery or by an external power source
connected to Port 1. Typically, one internal 2.4 ampere-hour battery provides
approximately 5.3 hours of operation during an RTK survey using the internal radio in
rover mode and approximately 3.5 hours of operation as an RTK base (this varies
according to temperature and wireless data rate).
If an external power source is connected to Port 1, it is used in preference to the
internal battery. When there is no external power source connected, or if the external
power supply fails, the internal battery is used.
CWARNING – Avoid contact with the rechargeable Lithium-ion battery if it appears to be
leaking. Battery fluid is corrosive, and contact with it can result in personal injury and/or
property damage.
To prevent injury or damage:
– If the battery leaks, avoid contact with the battery fluid.
– If battery fluid gets into your eyes, immediately rinse your eyes with clean water and
seek medical attention. Do not rub your eyes!
– If battery fluid gets onto your skin or clothing, immediately use clean water to wash off
the battery fluid.
The receiver is supplied with two rechargeable Lithium-ion batteries, and a dual
battery charger. The two batteries charge sequentially and take approximately four
hours each to fully charge.
147.1 Battery charging and storage
All battery types discharge over time when they are not being used. Batteries also
discharge faster in colder temperatures. If a Lithium-ion battery is to be stored for long
periods of time, make sure it is fully charged before storing and re-charged at least
every three months.
14 General Operation
94 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide
Trimble R6 GPS and R8 GNSS Receiver Operation
CWARNING – Charge and use the rechargeable Lithium-ion battery only in strict
accordance with the instructions. Charging or using the battery in unauthorized
equipment can cause an explosion or fire, and can result in personal injury and/or
equipment damage.
To prevent injury or damage:
– Do not charge or use the battery if it appears to be damaged or leaking.
– Charge the Lithium-ion battery only in a Trimble product that is specified to charge it.
Be sure to follow all instructions that are provided with the battery charger.
– Discontinue charging a battery that gives off extreme heat or a burning odor.
– Use the battery only in Trimble equipment that is specified to use it.
– Use the battery only for its intended use and according to the instructions in the product
documentation.
Charging the Lithium-ion battery
The rechargeable Lithium-ion battery is supplied partially charged. Charge the battery
completely before using it for the first time. If the battery has been stored for longer
than six months, charge it before use.
To protect the battery from deep discharge (5 V or less), the receiver is designed to
switch batteries or cease drawing power when the battery pack discharges to 5.9 V.
A battery that has reached the deep discharge level cannot be recharged and must be
replaced. The following recommendations provide optimal performance and extend
the life of your batteries:
•Fully charge all new batteries prior to use.
•Do not allow the batteries to discharge below 5 V.
•Keep all batteries on continuous charge when not in use. Batteries may be kept
on charge indefinitely without damage to the receiver or batteries.
•Do not store batteries in the receiver or external charger unless power is applied.
•If you must store the batteries, fully charge them before storing and then
recharge them at least every three months.
Disposing of the rechargeable Lithium-ion battery
Discharge the Lithium-ion battery before disposing of it. When disposing of the
battery, be sure to do so in an environmentally sensitive manner. Adhere to any local
and national regulations concerning battery disposal or recycling.
147.2 Power output

Configuration 15
In this chapter:
QConfiguring the receiver in real
time
QConfiguring the receiver using
application files
QApplication files
The Trimble R6 GPS and R8 GNSS receivers have
no controls to change settings. To configure the
receiver, use external software such as GPS
Configurator, WinFlash, or Trimble Survey
Controller.
There are two ways to configure the receiver. You
can:
•configure the receiver in real time
•apply the settings in an application file
This chapter provides a brief overview of each of
these methods and describes the contents and
use of application files.
15 Configuration
98 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide
Trimble R6 GPS and R8 GNSS Receiver Operation
15.1Configuring the receiver in real time
GPS Configurator and Trimble Survey Controller software support real-time
configuration of the receiver.
When you configure the receiver in real time, you use one of these software
applications to specify which settings you want to change. When you apply the
changes, the receiver settings change immediately.
Any changes that you apply to the receiver are reflected in the current application file,
which is always present in the receiver. The current application file always records the
most recent configuration, so if you apply further changes (either in real time or using
an application file) the current file is updated and there is no record of the changes that
you applied originally.
For more information on configuring the receiver in real time, see Chapter 16, Software
Utilities.
15.2Configuring the receiver using application files
An application file contains information for configuring a receiver. To configure a
receiver using an application file, you need to create the application file, transfer it to
the receiver and then apply the file’s settings. The GPS Configurator software does this
automatically when you work with configuration files.
For more information on applying application files, see Chapter 16, Software Utilities.
15.3Application files
An application file is organized into records. Each record stores configuration
information for a particular area of receiver operation. Application files can include the
following records:
•File Storage
•General Controls
•Serial Port Baud/Format
•Reference Position
•Logging Rate
•SV Enable/Disable
•Output Message
•Antenna
•Device Control
•Static/Kinematic
•Input Message
Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 99
Configuration 15
Trimble R6 GPS and R8 GNSS Receiver Operation
An application file does not have to contain all of these records. When you apply an
application file, any option that is not included in the records in the file remains at its
current setting. For example, if you apply an application file that only specifies the
elevation mask to use, all other settings remain as they were before the application file
was applied.
You can store up to twenty different application files in the receiver. You can apply an
application file’s settings at the time it is transferred to the receiver, or at any time
afterwards.
153.1 Special application files
The receiver has three special application files, which control important aspects of the
receiver’s configuration.
Default application file
The default application file (Default.cfg) contains the original receiver configuration,
and cannot be changed. This file configures the receiver after it is reset. You can reset
the receiver by holding down [P] for at least 15 seconds, or by using the reset option in
the GPS Configurator software.
For more information, see Default settings, page 116.
Although you cannot change or delete the default application file, you can use a power
up application file to override any or all of the default settings.
Current application file
The current application file (Current.cfg) reflects the current receiver configuration.
Whenever you change the receiver’s configuration, either in real time or by applying an
application file, the current file changes to match the new configuration.
You cannot delete the current file or change it directly, but every change to the
receiver’s current configuration is applied to the current file as well.
When you switch off the receiver then turn it on again, all the settings from the current
application file are applied, so you do not lose any changes that you have made. The
only exceptions are the following logging parameters:
•Logging rate
•Position rate
•Elevation mask
These parameters are always reset to the factory default values whenever the receiver
is switched off.
15 Configuration
100 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide
Trimble R6 GPS and R8 GNSS Receiver Operation
Power up application file
The power up application file (Power_up.cfg) is used to set the receiver to a specific
configuration any time the unit is powered up.
In this file, you can specify that the receiver is reset to defaults before the power up
settings are applied. This ensures that restarting the receiver always resets it to factory
defaults prior to applying the power up application file.
Alternatively, you can specify that the power up settings are applied immediately after
the current application file’s settings have been applied. Restarting the receiver results
in a configuration that uses your default settings for the options you define in the
power up file, but the current settings for all other options.
By default, there is no power_up application file on the receiver. To use a power up
application file, you must create and save a power_up application file in the GPS
Configurator software. If you save this file to disk, the file is called power_up.cfg. The
extension .cfg is used, by convention, to identify application files on the office
computer. When you transfer this file to the receiver, the file is saved on the receiver as
power_up, and becomes the new power up file.
The power up file is the only special application file that you can overwrite or delete
from the receiver.
153.2 Applying application files
An application file’s settings do not affect the receiver’s configuration until you apply
the application file. You can do this at the same time that you save the file.
Alternatively, you can save the file on the computer or in the receiver, then open it later
and apply its settings.
153.3 Storing application files
You can store application files that you create in the GPS Configurator software on the
receiver and on the computer. For example, each file can represent a different user
sharing the same receiver, or a particular mode of operation or survey style. Saving
application files on your computer as well as in your receiver is optional, but it is useful
because:
•it gives you a permanent copy of the settings you have sent to a receiver, for
audit or your own reference.
•you can use the same file to configure multiple receivers identically.
•you can use an existing application file as a template to create other application
files with similar settings.
Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide 101
Configuration 15
Trimble R6 GPS and R8 GNSS Receiver Operation
153.4 Naming application files
The application filename in the office computer and in the receiver are always the
same. This makes it easier to recognize and keep track of your application files.
When you change the name of the application file in the receiver, this changes the
application filename on your computer. When you transfer an application file from the
receiver and save it to the computer, the system renames the file to match the internal
receiver file. However, if you use Windows Explorer, for example, to change the .cfg
filename on the computer, this does not change the internal receiver filename. This
means that the GPS receiver does not recognize the change to the filename on the
computer.

Trimble R6 GPS and R8 GNSS Receiver Operation
182.1 Default behavior
The factory defaults specified above are applied whenever you start the receiver. If a
power up file is present in the receiver, its settings are applied immediately after the
default settings, so you can use a power up file to define your own set of defaults.
182.2 Power up settings
When you turn off the receiver, any changes that you have made to logging settings are
lost and these settings are returned to the factory defaults. Other settings remain as
defined in the current file. The next time you turn on the receiver, the receiver checks
for a power up file and, if one is present, applies the settings in this file.

Trimble R6 and R7 GPS/R8 GNSS Receiver Operation
A.1 NMEA-0183 Outputs
When NMEA-0183 output is enabled, a subset of NMEA-0183 messages can be output
to external instruments and equipment connected to the Trimble receiver serial ports.
These NMEA-0183 messages let external devices use selected data collected or
computed by the receiver.
All messages conform to the NMEA-0183 version 3.01 format. All begin with $ and end
with a carriage return and a line feed. Data fields follow comma (,) delimiters and are
variable in length. Null fields still follow comma (,) delimiters but contain no
information.
An asterisk (*) delimiter and checksum value follow the last field of data contained in
an NMEA-0183 message. The checksum is the 8-bit exclusive OR of all characters in the
message, including the commas between fields, but not including the $ and asterisk
delimiters. The hexadecimal result is converted to two ASCII characters (0–9, A–F).
The most significant character appears first.
The following table summarizes the set of NMEA messages supported by the receiver,
and shows the page where detailed information about each message can be found.
To enable or disable the output of individual NMEA messages, do one of the following:
•Create an application file in the GPS Configurator software that contains NMEA
output settings and then send the file to the receiver.
•Add NMEA outputs in the Serial outputs tab of the GPS Configurator software
and then apply the settings.

The SV Tracking LED is
not flashing.
The receiver is tracking fewer
than four satellites.
Wait until the SV Tracking LED is
flashing slowly.
The radio antenna cable and
GPS antenna cable are mixed
up.
Make sure that the GPS antenna
cable (with the yellow over-mould) is
connected between the yellow TNC
connector marked GPS and the GPS
antenna.

Troubleshooting C
Trimble R6 and R7 GPS/R8 GNSS Receiver Operation
C.2 Receiver issues
The following table describes some possible receiver issues, possible causes, and how
to solve them.
Issue Possible cause Solution
The receiver does not
turn on.
External power too low. Check the charge on the external
battery, and check the fuse if
applicable. Replace the battery if
necessary.
Internal power too low. Check the charge on the internal
batteries and replace if necessary.
Ensure battery contacts are clean.
External power not properly
connected.
Check that the Lemo connection is
seated properly.
Check for broken or bent pins in the
connector.
Faulty power cable. Try a different cable.
Check pinouts with multimeter to
ensure internal wiring is intact.
Receiver does not log
data.
Insufficient internal memory. Delete old files using the GPS
Configurator or Trimble Survey
Controller software, or by holding
down [P] for 30 seconds.
The receiver is tracking fewer
than four satellites.
Wait until the SV Tracking LED is
flashing slowly.
The receiver is not
responding.
Receiver needs soft reset. Power down the receiver and power
back up.
Receiver needs full reset. Hold down [P] for 30 seconds.
If you want to retain data files,
remove the CompactFlash card first.
Reference receiver is
not broadcasting.
Port settings between
reference receiver and radio
are incorrect.
Using the Trimble Survey Controller
software, connect to the reference
radio through the receiver. If no
connection is made, connect directly
to the radio and change the port
settings. Try to connect through the
receiver again to ensure that they are
communicating.
Faulty cable between receiver
and radio.
Try a different cable.
Examine the ports for missing pins.
Use a multimeter to check pinouts.
No power to radio. If the radio has its own power supply,
check the charge and connections.
C Troubleshooting
144 Trimble R6/R7 GPS and Trimble R8 GNSS Receivers User Guide
Trimble R6 and R7 GPS/R8 GNSS Receiver Operation
Roving receiver is not
receiving radio.
Reference receiver is not
broadcasting.
See above.
Incorrect over air baud rates
between reference and rover.
Connect to the roving receiver’s radio
and check to ensure it has the same
setting as the reference receiver.
Incorrect port settings
between roving external
radio and receiver.
If the radio is receiving data (the
Logging/Memory LED is flashing) and
the receiver is not getting radio
communications, use Trimble Survey
Controller to check that the port
settings are correct.
The cellular modem does not
have hardware flow control
enabled.
Disable flow control on the modem.
Use a special cable. For more
information, refer to the document
Using Cellular and CDPD Modems for
RTK, which is available from the
Trimble website.
