on the back of the unit via the 94000-115200 Console Cable. The 4380A is a DTE device utilizing the
RS232 communication protocol. Settings for the port are 115,200 baud, 8 data bits, 1 stop bit, no parity,
and no flow control. It is sometimes necessary to access the system via the USB port because the 4380A
may not be accessible via the network until the IP Address has been set.

4380A provides diagnostic output that can aid in identifying system errors. It is typically not necessary for
users to access the diagnostic port because all system errors are reported on the front panel (Alarm Light),
in the alarms list (
