3.2 Connecting the PC
The Maintenance Console serves as an overall system programming tool for the PBX. The Maintenance
Console’s Quick Setup lets you easily configure the PBX to apply basic settings such as time and date.
To programme the PBX, connect it to the PC via the MNT or RS-232C port.

CAUTION
When connecting a PC to the PBX via the RS-232C port, it is necessary to keep the following in mind to
protect the system:
1.
Make sure that both connector cases (frame ground) of the RS-232C cross cable (shielded cable) are
conductive. If they are not conductive, make sure that both connector cases of the cable are firmly
connected.
2.
If this is not possible, connect the frame of the PBX to the frame of the PC using an earthing wire in
order to prevent difference in the electrical potentials.
