12. Wired Replication Mode
If the wired replication function is set, the intercom will not quit after entering the wired replication
mode. If it returns to the user mode, the user needs to restart the machine.
The operating steps go as follows:
1 Press [P1] and [P2] buttons for power-on to show “CLONE” (for two seconds) and enter the
replication mode. If such a mode is not allowed, it will enter the user mode.
2 Connect the pickaback plane with the wired replication cable first, and then turn on the power
button for the pickaback plane.
3 Press the host [P4] button for replication. At this time the red host indicator will light and the
data will be transmitted to the pickaback plane from the host. In the period when the pickaback
plane receives the data, it will show “PROGRAM” and the green indicator light. The host will
show “SUCCESS” and the pickaback plane will automatically restart upon receipt of all data.
4 Press the [P4] button and the host will return to the replication mode. Continuous replication
will start from Step 3.
Note: The wired replication mode can be started or prohibited through the PC program software.
Once such a mode is prohibited, the intercom can’t enter the wired replication mode.
