The 9-pin RS-232 connector on the front of the HRU-419 allows you to
connect your system to a maintenance terminal or PC running a terminal
emulation program with a standard RS-232 cable. Once connected to a
maintenance terminal, you can access the view-only Maintenance and
Remote Terminal menus (the Set Clock option is the only user-configurable
option on the HRU-419).
Figure 4 shows the HRU-419 DB-9 RS-232 I/O.

The maintenance terminal is configured as DTE. To connect the HRU-419 to
a maintenance terminal, connect the RS-232 port of the maintenance terminal
to the HRU-419 front-panel Craft port using a serial interface cable
(
