PLR5000 Modem Configuration 
The PLR5000 allows you to set several parameters to suit your particular application. All adjustments are 
done through the PLR5000 setup program, a user interface that eliminates the need for setup diskettes, DIP 
switch settings or custom software. 
To access the configuration menu, connect the radio modem to any terminal program with port settings of 
19.2Kbaud, 8 data bits, no parity and one stop bit. With the modem connected to the PC running the terminal 
program, press the Configure button located behind the pinhole next to the DB-9 connector on the front of the 
modem. While any terminal program that can be set to 19200 baud will work, examples for this user guide 
were generated using the Microsoft Windows 2000 application “HyperTerminal.” 
Note: When using HyperTerminal, set Handshaking to none.

When the setup program is invoked, the “O” LED on the PLR5000 front panel will flash once when the 
Configure button is pressed and the “C” LED will remain on for the entire time the radio modem is in setup 
mode. 
The main menu provides the radio modem’s unique call book number and the set of choices for editing the 
operational parameters and viewing the performance data.
