AE-C2 Controller Card
Ports 1, 2 and 3 – RS-485 Serial Communications (Control Surfaces)
Control Surface serial communications connections are made at the connectors Port 1, Port 2, or
Port 3 on the AE-C2 Communications Controller. Attach the control cable using a DB9M
connector using the same pinout as at the Control Surface.
Ports 1 to 3 are RS-485, operating at 38.4Kbps, 8 data bits, 1 stop bit and even parity.
 See Appendix C for connector pinouts.
Port 3 – Surface Cue Audio Requirements
Note that Port 3 does not have connections for digital cue audio to return to the Control Surface. If
this port is used for a Control Surface, external wiring is required for cue audio.
 See Appendix C for connector pinouts and a Port 3 Cue Audio wiring diagram.
Port 4 – RS-232 Serial Communications (PC/Supervisor)
Port 4 is for connection to a PC for uploading of configuration data, remote control and monitoring.
Port 4 requires a DB9M connector.
Port 4 is RS-232 operating at 38.4Kbps, 8 data bits, 1 stop bit and even parity.
 See Appendix C for connector pinouts.
