ECC-RM Remote Microphone
Installation
2.9 ECC-RM Remote Microphone
Connections are made from TB24, TB12, and TB22 on the ECC-50/100 main control board to
TB3, TB2, and TB1 on the RM. If the ECC-RM is the last device on the audio and data bus chain,
signal terminations are required. For the external data bus, a removable jumper must be on pins 1
and 2 of JS4. If the ECC-RM is not the last device, the jumper must be on pins 2 and 3 of JS4. For
the external audio riser, termination ELR-15K must be on pins 4 and 5 on TB2. T-taps and multiple
home runs to the main control board are not allowed for the external data bus or the external data
riser.
