  • Page 28: Operating Serial Controllers

    C.2.1 Entering BCS Commands AutoPatch Distribution matrices are programmed using a set of ASCII characters called Basic Control Structure (BCS). BCS command syntax is designed to parallel the operations of the control panel. So instead of pressing the keys on the control panel, press the keys on the external serial controller keypad.
  • Page 29 Appendix C serial protocol is as follows: half- 9600 baud 8 data bits 1 stop bit No parity All BCS entries must be complete commands. Terminate any incomplete or erroneous commands with an ‘X’ (Cancel) and then re-type the command. Typing a space or a backspace does not cancel a previous command.

  • Page 30: Bcs Software Handshaking

    C.2.2 BCS Software Handshaking All AutoPatch software provides software handshaking. However, other software may not. If you are using something other than AutoPatch software, make sure it implements the following handshaking requirements. Each character received by the distribution matrix CPU is echoed through the DB-9 port.
