Diagnostic RS232 Serial Communications
The MPI 6000 can communicate via a serial, RS232, communications protocol
(
Table 6-4). The diagnostic RS232 port can be used to display the operating system
boot sequence.
If you connect the MPI 6000 directly to a host PC serial port, you must use a null-
modem connector.
Diagnostic Commands (Mike?)
By using the version command, you can display data about the configuration of the
MPI 6000 including its Internet protocol (IP) address.
The RS-232 diagnostic connector can be used to check the external input/output sta-
tus. Table 6-5 lists this connector pin assignments.
