The most thorough troubleshooting method for debugging the operation of the
MCM driver (and the gateway in general) is the powerful Debug port on the
gateway. Accessing the Debug capabilities of the gateway is accomplished by
connecting a PC to the Debug port and loading a terminal program such as
ProSoft Configuration Builder or Windows HyperTerminal.
Note: 4101 series modules that use both serial ports (Debug and Port x) as application ports (for
example, 4101-MCM-DFCM) must be reset or power-cycled in order to enable the selected port as
a Debug port. To enable the debug port, connect to the port using a null-modem serial cable, and
then press and hold the [A] key on the keyboard while resetting or power cycling the card. Do not
release the key until HyperTerminal shows the debug port menu. Debug mode can be enabled on
either port. The upload/download command is only available when connected to the Debug port.
