Figure 5 - PD L Low Pow er B ase Setup

P D L U ser's G uide

The RX LED indicates that the PDL LPB is receiving an RF carrier signal from another PDL Base or from

another source of interference. During normal operation, the RX LED will flash at a once-per-second rate

indicating the transmissions from the PDL Base. If the RX LED is on continuously, then a source of

interference may be impacting the ability of the PDL LPB to receive data. Try repositioning the antenna,

or you may need to change to another channel at both the base and rover to reduce or eliminate the

interference.

The TX LED indicates that the PDL LPB is broadcasting. In most GPS RTK applications, the TX LED will

flash approximately one time per second.

Enclosure

The PDL LPB enclosure is a tough, impact resistant blue polycarbonate with machined aluminum end

caps. Black bumpers with integrated gaskets provide the first level of shock protection for the internal

components. An additional isolation system inside the enclosure reduces vibration impact to the sensitive

radio receiver board.

Antenna Mount

The integrated antenna mount provides an industry standard NMO style RF connector that is compatible

with a wide range of mobile whip antennas.

Range Pole Mount

The bottom end cap is female threaded with 5/8-11 UNC that is compatible with common range poles.

The unit is easily mounted in the place of a

stand-alone antenna and eliminates the need

for an antenna cable.

PDL Low Power Base Setup

Antenna and Antenna Mount

Screw the Antenna on the antenna mount of the

PDL LPB. We recommend inspecting the

antenna center push-pin contact to make sure

that it makes good contact with the antenna

mount. A good antenna connection is critical to

system performance.

Range Pole or Tripod Side Bracket Mount

Before connecting any cables, screw the PDL

LPB onto the range pole (for tripod-top use) or

tripod side mount bracket.

Connecting the PDL LPB

The PDL LPB is connected to the GPS RTK

receiver using the supplied cable. After

connecting the cable, press the ON/OFF

button. Use the CHANNEL button to select the

channel of operation, or select "r" for the

AutoRover function or select " b " for the

AutoBase function. Refer to the How to Use

AutoRover and How to Use AutoBase sections

of this manual for detailed instructions

concerning these features.
