Switching control by computer
The OPTIONS port allows an external serial input, typically from a computer, to
control the selection of the various channels. You can use either the supplied
FlashUpgradeAdaptorplusastandardCAT5patchcable(partnumberVSC23)
or alternatively construct a custom cable to link the CCS4-USB unit and the
computer. For pin-out details of the custom cable, see Appendix 1.
Upon receipt of the correct code, the CCS4-USB will switch immediately to the
appropriate channel.
