2.3.1 Link and Switch Settings
The 3200 may be controlled via its local port, a DCE V.24 RS-232 serial
interface. This port is configured by switch SW1 on the front of the
system control card DTE221. Switch SW1 is read at power up and
periodically to allow configuration of the local port to be modified once
powered up. Switches S2 to S8 of SW1 control the setup of local port.
Options available are shown in Table 2-5.
Switch S1 of SW1 allows the operator to communicate locally with a unit
when it is normally operating as a remote unit in Local/Remote mode.
The links on the System Controller should be in the following positions:-
LK1 2-3
LK2 2-3
LK3 2-3 For normal operation, 1-2 for redundant controller operation
LK4 2-3
LK5 1-2
LK6 1-2
LK7 1-2 RAM backup battery connected. (2-3 = disconnected) *
LK8 2-3
* Note: The unit should
NOT be operated with the battery disconnected.
