3.9 Master/Slave Configuration
You can use the LRP2000 in a single or dual antenna configuration. All LRP2000s are set by default to be
master controllers for single antenna systems. For dual antenna systems, you must make one jumper
change to the master and change the second controller to a slave.
To change an LRP2000 to act as a slave, you need to perform the following tasks:
Move a shunt from jumper J34 to jumper J32 (master LRP200).
Make DIP switch setting changes to DIP switch banks S1 and S2 (slave LRP200).
Change the location of jumper J16 (slave LRP200).
The following sections describe how to make these changes.

3.9.1 Setting Jumper 32 on the Master

You must make one jumper change to the LRP2000 you have selected to be the master.
To set jumper 32 for a dual antenna master:
1. Verify that power to the LRP2000 is off.
2. Locate jumper 32 and jumper 34 as shown in Figure 32.

3. Remove the shunt from jumper 34 and place it over jumper 32.
