4. Verify the current frequency plan configuration. To verify the plan, check the connections between the

J connectors (located on the board and labeled J1 and J2) and the Chan connectors (located on the

diplexer). The Chan connectors are labeled 2421 (Chan 1) and 2462 (Chan 2) for most TRACER 4103

systems and CH1 and CH2 for most TRACER 4203 systems. The following table outlines the

connections for Plan A and B.

5. Using the torque wrench, disconnect both cables from the Chan connectors on the diplexer. Do not

attempt to disconnect the J connectors (located on the board) as this will cause damage. Click

a digital picture of this step.

6. Carefully flex the cables to swap the connections. Be careful with the RF cables, making sure that the

minimum bend radius of the cable is greater than 0.75"; bends and loops smaller than a quarter will

cause the RF cable to break. Use the wiring guidelines in Figure 3 and Figure 4 on page 4 for help with

wire placement. Click

Allowing the RF cables to sit on the processor and radio boards (green) could cause

damage to the boards; keep the RF cables off the boards while re-routing them. Click
