PDL/ADL/SDL 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.

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
Mast. You may want to leave the mount permanently attached to the mast and avoid this step in the
future.
