The SCT device uses a firewire connector/cable on the unit for ease of connection, but all it does is connects the device to the wideband with pigtails on the other end. The signal is a standard analog DC output into the SCT. You can get a 6-conductor firewire(1394) cable and cut the connector off one end and use that. I would only suggest this if you are comfortable with identifying the proper pinout for the signal.
