speed, wireless data link that is designed specifically for
GPS/RTK applications. Your success in using the PDL is our
primary goal. We stand behind our product with expert support
and service. We welcome your comments and questions.
Scope
This guide introduces the PDL Base and rover radio link systems
used for GPS and RTK applications. It is written for the first-time
user, and gives details concerning system setup, operation and
maintenance. We urge you to take the time to review this short
manual completely prior to setting up your system.
Note Concerning this Guide
We believe that the PDL system provides the best value and
performance for the user. As such, we provide our equipment in
complete turnkey systems, including all of the items necessary
for operation with your GPS.
You may have purchased your PDL from a third party. On
occasion, the bundled product provided by these sources may
differ from the kits provided directly from Pacific Crest
Corporation. If this guide does not accurately reflect the
equipment that you received, please contact your supplier for
specific instructions concerning the setup of items that differ.

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.
6 Setting Up the PDL High Power Base
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.
PDL User's Guide 7
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.
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.

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.

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 Mast. You may want to
leave the mount permanently attached to the mast and avoid this
step in the future.
Next, screw the Antenna on the Antenna Mount. We
recommend inspecting the antenna center push-pin contact to
ensure that it makes good contact with the antenna mount. A
good antenna connection is critical to system performance.
Tripod Antenna Mast
With the Antenna Mount and Antenna connected, extend the
legs of the Tripod Antenna Mast and set up the tripod on level
ground. Spread the tripod legs sufficiently to provide a stable
base.
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.

Caution: Do not extend the antenna mast in conditions

of high wind or in situations where the uneven terrain or
other soil conditions provide an unstable base. Keep
the area surrounding the Tripod Antenna Mast clear
and exercise caution to prevent injury or damage to
property should the Tripod Antenna Mast fall.
Connecting the PDL HPB
The PDL HPB has a built-in tripod mounting bracket that allows
easy mounting to the tripod. Locate the mounting flange at the
top portion of one of the Tripod legs, and hook the PDL HPB in
place.
