To connect shield:
1. Connect the shield at the BCU (TB2) to provide a drain for RFI/EMI,
and then splice it with other RTA/RTW shields at the RTA/RTW end.
2. Tape the shield at the last RTA/RTW in the chain to prevent any con-
nection between the shield and ground (see Figure 46).
IMPORTANT
UCM ground loops will cause a malfunction.

Each UCM must have a unique address on each link. On the RTA/RTW,
addresses are set from the front panel. Refer to the RTA/RTW installa-
