AE-C6 Controller Card
Ports 1 to 6 - RS-485 Serial Communications (Control Surfaces)
Control Surface serial communications connections are made at the RJ-45 connectors Port 1
through Port 6 on the AE-C6 Communications Controller. Attach the control cable using a
standard RJ-45 CAT5 data cable to the Control Surface. Mosaic and Artisan surfaces accept the
other end of a standard CAT5 data cable without any modification being necessary.
Console /Control Surfaces may only be connected to Ports 1, 2 and 3 as defined in AEConfig. Ports
4, 5 and 6 may only be used by Utility Panels.
Utility Panels may be used on Ports 1-3 if they have not been defined in AEConfig as a Console.
Ports 1 to 6 are RS-485, operating at 38.4Kbps, 8 data bits, 1 stop bit and even parity.
 See Appendix C for connector pinouts.
Ports 7 & 8 – RS-232/RS-485 Serial Communications (PC/Supervisor)
Ports 7 and 8 are for connection to a PC for uploading of configuration data, remote control and
monitoring. Ports 7 and 8 require an RJ-45M crimp connector, and generally this cable will need to
be custom made, or an RJ45 to DB9 adaptor made for the PC end.
Ports 7 & 8 will switch automatically between RS-485 and RS-232, operating at 38.4Kbps, 8 data
bits, 1 stop bit and even parity.
 See Appendix C for connector pinouts.
GPI Inputs & Outputs
The AE-C6 Communications Controller provides 15 logic input connections along with 15 solid-
state closures for external device control. The first 12 switch outputs are on a DB25 connector, the
remaining three on a DB37 connector along with logic inputs.
GPI outputs are driven by non-polarized, solid state switches, rated at 500ma at 50V AC/DC, with
surge to 2A. These solid state devices do not conduct at low voltage, so cannot switch an audio
input. However, they are suitable for most control signals, and avoid problems with relay contacts
