ONNECTING TO A
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).
