4.9.1 Amplifier Alarms - MCPA Serial Interface (J1 – J6)
The MCPA Serial Interface is accomplished via a DB9 Female connector on J1. The SIM communicates with each
amplifier subrack in the cabinet via the host RS-485 interface on the MCPA subrack. RS-485 signals are daisy
chained from the first subrack to the next, and so on, until the buss is terminated. The SIM is internally terminated,
as are each of the amplifier subracks, to prevent loading down the RS-485 buss.
TBD alternate configuration: The MCPA Serial Interface is accomplished via six identical DB9 Female connectors.
