MR9600-100 Diagnostic Tests
If you suspect that your MR9600-100 is not functioning properly, you can run the following diagnostic
tests to test the MR9600-100’s hardware capabilities.
1. Refer to Figure 3 on page 12 to locate the test jumper on the MR9600-100 Controller card. Put the
test jumper into the loopback position, so the two pins are shorted together. Reinstall the MR9600-
100 assembly into the CC9600 chassis. Plug the 10Base-T loopback jumper into the Ethernet
connector labeled “LAN” on the rear of the CC9600 chassis.
2. Run MultiExpress or another datacomm program on a PC at 115,200 bps with no flow control .
Connect the COM port used by the datacomm program to the MR9600-100’s RS-232 port on the rear
of the CC9600 chassis.
