INTRODUCTION
Welcome
Thank you for purchasing the Positioning Data Link™ (PDL™) for use with your survey system. The
PDL is an advanced, high 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

SETTING UP THE PDL HIGH POWER BASE
Overview of PDL High Power Base (PDL HPB) Radio Modem
Front Panel
PDL User's Guide
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.
