7.8 OPTICAL INTERFACE ADAPTER REMOTE ACCESS
AND STATUS REPORTING
In IMUX 2000 multiplexers equipped with fiber optic interfaces, the Optical Interface Adapter (OIA)
plugs in as a Module Adapter behind the CM4 Common Module. Though it serves the function of a
Module Adapter, it acts as a channel module to the SCB (Serial Control Bus).
The OIA will always have a fixed channel address. When DIP switches SW1-1 and SW1-2 on the OIA
are set to the TERM or DI-A mode, the address is "C1." When SW1-1 and SW1-2 are set to the DI-B
mode, the address is "C3." The OIA reports itself as a "Type 11" module.
SRVC service is always on in the local mode, and may be turned off in the remote mode. However,
this has no effect on the module.
CHANNEL CARD 1 (or 3) TYPE 11
There is only one remote configuration setting ("P" code) for the OIA, as listed in Table 7-5. The
remote status messages ("S" codes) for the OIA are listed in Table 7-6.
