Troubleshooting Communications
Use the following checklist if communication cannot be established with the
QM-RMC.
1. Verify that you are using the correct cables. As described
previously, an RS-232 connection requires a null modem. TCP/IP
connection requires a CAT5 cable with 8-pin RJ-45 connectors.
2. With a serial connection, verify that the correct COM port on the
PC has been selected. Some computers have more than one COM
port; some may be internal (e.g., for a modem). Consult the
