PRINCIPLE The MFC-CB has two RS232 communications ports referred to as COM1 and COM2 and a single IEEE-488 port. COM1 and the IEEE-488 port are for communicating with a host computer (see Section 3. 4. 5). COM2 is reserved for communicating with an external device (e. g. , a multimeter, molbox, second MFC-CB, etc. ). All the communication ports can be set up from the MFC-CB front panel. MFC-CB provides a self-test for its RS232 communication ports. The self-test allows verification that the MFC-CB RS232 ports (COM1 and COM2) are operating properly and that a valid interface cable is being used.
