Switching control via the Options port
The OPTIONS port allows an external serial input, typically from a computer, to control
the selection of the various channels. You can use either an optional serial cable (part
number VSC40) or alternatively construct a custom cable to link the CCS-PRO4 switch
and the computer. For pin-out details of the custom cable, see Appendix 1.
Upon receipt of the correct code, the CCS-PRO4 will switch immediately to the
appropriate channel.
Connecting a computer for remote control
The cable link from the computer needs to connect the transmit (TXD) line of the
computer to the receive (RXD) input of the CCS-PRO4 and also link the ground
terminals (GND) of the two devices. See Appendix 1 for details.
To connect a computer remote control
1 Use an optional serial cable to link the OPTIONS port on the rear panel of the CCS-
PRO4 switch and a vacant serial port on the computer.
Serial port parameter settings
Ensure that the chosen serial port is congured to the following:
• Baud rate: 1200
• Data bits: 8
• Stop bit: 1
• Parity: None
Channel selection codes
ASCII
Character Hex Decimal
• Channel 1: ‘1’ 0x31 49
• Channel 2: ‘2’ 0x32 50
• Channel 3: ‘3’ 0x33 51
• Channel 4: ‘4’ 0x34 52
Note: If the optional CCS-XB module is used with the CCS-PRO4, connect the computer
instead to the TO KEYPAD OR PC port on the CCS-XB module.
IMPORTANT: Do not
connect the OPTIONS
port to any network.
