SETTING UP THE PDL HIGH POWER BASE
Overview of PDL High Power Base (PDL HPB) Radio Modem
Front Panel
Figure 1 - PDL High Power Base Front Pane
Buttons
The ON/OFF button is used to turn the PDL HPB station on and off. Turn the unit on by pressing the
ON/OFF button and holding it until the channel display indicator is lit. Turn off the PDL HPB by pressing
the ON/OFF button until the display goes blank. There is a one-second turn-off delay in the power button
to prevent inadvertent turn off.
The CHANNEL button is used to display and change the channel. Press the CHANNEL button
momentarily to display the selected channel. To change the channel, press the CHANNEL button once
to light the display, and then again to change the channel.
Use the CHANNEL button to select the "b" setting. With "b" selected, the PDL HPB will be placed in
AutoBase mode. This mode selects the channel for transmission automatically.
Display
The seven-segment numeric display is used to indicate the channel or mode selection. To conserve
power, the display is only lit for a short time following the pressing of the CHANNEL or ON/OFF buttons.
Channel selections range from Channel 0 to Channel 15. Two digit channel numbers are displayed by
alternately flashing a 1 followed by the second digit.
The seven-segment display also has a decimal point to the lower right of the number. The decimal point
is lit to indicate that the channel selection was done automatically with AutoRover or AutoBase.
Indicator LEDs
The power LED has two purposes - first, to indicate that the unit is powered, and second, to indicate the
level of charge for the power supply. The power LED will blink to indicate that the base station battery is
at or below 10 Volts and may require charging.
The amplifier power LED indicates the RF power output level selected. When lit, the amplifier power
LED indicates that the RF output power is set to high. When blank, the amplifier power LED indicates
that the RF output power is set to low.
The TX LED indicates that the PDL HPB is actively transmitting. In most RTK applications, the base
station TX LED will blink once per second.
6
PDL User's Guide
The RX LED indicates that the PDL HPB is receiving an RF carrier signal. If the RX LED is lit for
extended periods of time, or continuously, then another radio station is operating on the same frequency.
This competing RF source may interfere with the GPS RTK system, and may require that you change
channels for better performance.
Rear Panel
Data Connector
A five-pin circular LEMO style receptacle accepts both programming and GPS model specific cables.
The supplied cables are labeled "RADIO" on the end that plugs into the base. Align the red dot on the
plug with the red dot on the receptacle and push until a clicking sound is heard.
To remove the cable, grasp the blue cable over-mold, and retract the locking mechanism by pulling the
knurled barrel of the plug toward your palm.
Figure 2 - PDL High Power Base Rear Panel
RF Connector
A BNC jack accepts the BNC male plug coming from the antenna mount.
High/Low RF Power Switch
This toggle switch selects high RF power output in the "up" position and low RF power output in the
"down" position. Select high RF power for situations where long range is required. For short range
applications, select low RF power to reduce power consumption and minimize interference with
co-channel users.
Enclosure
The PDL HPB enclosure is rugged extruded aluminum with integrated heat sink fins. The enclosure is
painted with a weather resistant powder coat blue paint. Black bumpers are integrated with front and
rear gaskets to provide shock protection and watertight operation. The enclosure is not designed to
withstand submersion and must not be allowed to sit in standing water.
Warning: The PDL HPB enclosure and heat sink may become very hot during operation. This is
normal depending on the ambient temperature, RF power selection and transmission duty cycle.
Turn off the unit and allow it to cool prior to handling.
PDL High Power Base System Setup
Antenna and Antenna Mount
Begin your PDL HPB station set up by screwing the Antenna Mount to the top of the Tripod Antenna

Battery Care
Base station kit shipments to North America include a 33 AHr deep-discharge gel lead acid battery. This
battery provides all day operation with ample power for both the PDL and the GPS RTK reference station.
International Shipments
For shipments outside of North America, we include battery bag, power cables with fuse, and hardware
for a user supplied battery. Select a deep discharge battery of the type designed for golf cart or wheel
chair operation, and that has a capacity of 33 AHr or greater. Batteries designed for automotive use will
be damaged by the repetitive discharge/charge cycles and should be avoided.
Charging
The supplied charger provides two-stage charging and should be connected to the battery following every
full day of operation to assure good battery life and performance. The first stage quickly charges the
battery to capacity and the second stage trickle charges the battery to maintain a full charge.
If the battery is maintained in storage for an extended length of time, it is important to periodically charge
the battery as extended time in a discharged state may damage the battery.

Battery Care
The PDL Rover has an internal power supply that allows all-day operation without taking power from the
GPS. The light-weight Lithium-Ion single cell battery can be recharged more than 1000 times, providing
3+ years of normal use. We recommend daily charging for best battery life and performance.
Warning: The internal Lithium-Ion battery is NOT USER SERVICEABLE. Do not attempt to open
the enclosure or replace the battery. Lithium-Ion batteries can be dangerous if mishandled.
The PDL Rover has a built-in charger that monitors and controls the charging of the internal battery. The
internal battery quickly charges in less than 4 hours, and can be charged with the supplied charger, or
from an external 12 volt supply. We recommend charging the internal battery at room temperature.
Charging is inhibited if the ambient temperature is below 0° C or above 40° C.
Warning: The internal battery must not be subject to operating temperatures below -20° C.
Subjecting the battery to conditions below -20° C will produce permanent battery damage, and is
not covered by the warranty.
TIPS AND TECHNIQUES FOR BEST PERFORMANCE
Antenna
Antenna placement is critical for good performance. Range and coverage is directly proportional to the
height of the transmitting and receiving antennas. Where possible, select a reference station location that
takes advantage of terrain to get the transmitting antenna as high as possible.
Always use the telescoping antenna mast, and raise the antenna as high as is practical and safe, given
terrain and wind conditions.
Power Supplies
Maintain batteries in a fully charged state. Both the PDL Base and internal PDL Rover batteries will live
longer if not allowed to become completely discharged. We recommend routinely connecting both the
base and rover PDLs to their chargers on a nightly basis. This will assure optimal performance and long
battery life.
How to Use AutoRover™
AutoRover is a feature that allows the PDL Rover to automatically synchronize to the PDL Base. Enable
this feature by pressing the CHANNEL button until an "r" is displayed. After selecting "r", you will note
that the display will flash each programmed channel for approximately 3 seconds, until a base station
broadcast is encountered. The PDL Rover will continue to scan until a broadcast is found.
The next time you turn on your unit, you will see an "r" momentarily, after which the scan process will
begin. To manually select a channel for operation, press the CHANNEL button until the desired channel
is displayed.
With AutoRover the PDL Rover scans each programmed operating frequency, looking for a signal from
the PDL Base. When a signal is found, the PDL Rover selects that channel for operation.
Caution: Multiple PDL Base stations operating in a single area may lead to the PDL Rover
selecting the wrong base. In such circumstances, we recommend manually selecting the channel.
How to Use AutoBase™
AutoBase is a feature that allows the PDL Base to automatically select a channel based on a channel
selection algorithm. These features can be selectively turned off to allow you to manually select the
channel of operation on both the PDL Base and Rover.
15
PDL User's Guide
To enable AutoBase, press the CHANNEL button on the PDL Base until an "b" is displayed. After
selecting "b", you will note that the display will flash each programmed channel for approximately
1 minute, during which time the channel is analyzed for background noise and co-channel interference.
After cycling through all channels, the PDL Base will select the channel that appears to provide the
clearest channel access. Following channel selection, the data received from the GPS will automatically
begin transmitting.
Warning: Depending on the number of channels programmed, channel selection can take from 1 to
16 minutes. We recommend that you set up and turn on your PDL Base station as soon as
possible during system setup to prevent delays.
Equipment Care
Routine equipment care will prolong the life and reliability of your PDL family products. Radio
communication equipment is susceptible to damage from shock or environmental extremes. Never
operate the PDL equipment out of the operating specifications contained in Appendix B.
Error Codes
The PDL performs a variety of power-up and run-time tests to assure optimal operation. Tests include
environmental as well as electrical measurements designed to avoid damage to the unit while maintaining
adequate operation. In the event of an error condition, a 3-digit error code is flashed on the display.
Error codes begin with an "E" followed by two numeric digits indicating the failure mode. Table 2 lists the

Being Part of the RF community
Operation of a licensed radio product makes you a member of the RF community. Be aware that virtually
all frequencies licensed are provided on a shared basis with other users. Each frequency used in RTK
GPS activities has certain restrictions and limitations. For complete information, refer to Part 90, Title 47,
of the Code of Federal Regulations.
Most frequencies sharing data transmissions and voice transmissions give priority to voice users. Be
mindful of the persistent nature of a GPS RTK data transmission and always limit your RF transmission
output power when performing close-in survey situations to avoid interference with co-channel users. We
recommend using the low RF power setting for construction site and other line-of-site surveys with
baselines less than 2 miles (depending on terrain).
Warning: If you are in conflict with a co-channel user, select another frequency to avoid formal
FCC actions. In most cases you are required to vacate a frequency upon complaint by a shared channel
voice user.
Most survey operations are itinerant in that the system is moved on a frequent basis. For fixed system
installations, you should not use frequencies set aside for itinerant operations, but should coordinate a
frequency based on the fixed area operation.
Regulations differ from country to country, so please be aware of the local regulations prior to using the
PDL equipment.
Automatic Station Identification
For operation in the United States, the FCC requires that radio transmitters used for GPS RTK
applications periodically broadcast a station identifier. The station identifier is the call sign assigned to
you on the station license.
The PDL supports the broadcast of station identification in a manner that meets the requirements of the
FCC. Upon receipt of equipment, program your FCC callsign into the configuration of your PDL using
PDLCONF software. This is only required for transmitters.
17
PDL User's Guide
Warning: Failure to transmit your station identification is in violation of FCC regulations. Use
PDLCONF software to enter your FCC callsign.
Carrier Sense Multiple Access (CSMA)
CSMA is a technology implemented in the PDL Base to meet FCC transmitter requirements. CSMA
holds off the radio transmission if the frequency is currently being used by a co-channel user. On
occasion, you may note that the radio broadcasts stop for short periods of time. Most often, this is a case
of co-channel interference and the PDL Base is holding off broadcasts due to the FCC mandated CSMA.
GPS RTK equipment is designed to function with intermittent gaps in the data. Heavy co-channel use
may limit the ability of the PDL Base to transmit the required information. In areas of heavy co-channel
usage, try changing channels to a less used frequency.
