Features:
- Defined serial roles: The module assigns operator-station peripherals to numbered ports.
- Hardware configuration: Jumpers and DIP switches retain the installed communication setup.
- OIS integration: The board supports documented OIS20, OIS25 and MCS station arrangements.
The module is identified by its Multibus position and peripheral interface role rather than by a generic serial-board description.
Each port has a documented purpose, allowing keyboard, printer and diagnostic paths to be traced separately during service.
A successful exchange preserves switch settings, memory selection and cable-to-port mapping before the station is restarted.
Apter Power can support procurement for the ABB Bailey IIMSM01 Multibus Serial Interface Module after operator-station type, port map and hardware settings are documented.

Important Notice: No qualified exact-model English PDF is attached. Use the complete product model in every document request.
- Keyboard paths: Ports 1 and 2 serve the two documented keyboard connections.
- Printer paths: Ports 5 and 7 are assigned to the first and second printers.
- Diagnostic access: Port 8 provides the documented diagnostic-terminal connection.
- Reserved position: Treat port 4 according to the station documentation rather than as a spare universal port.
- Switch record: Capture every DIP-switch position before removing the operating module.
- Jumper identity: Preserve installed jumper placement instead of assuming factory defaults.
- RAM selection: Match the documented 16K or 64K memory setting for the station.
- One-change discipline: Restore the original setup before diagnosing any new peripheral fault.
- Cable labels: Mark each keyboard, printer and diagnostic lead by port before disconnection.
- Sequential test: Prove operator input first, then printers and diagnostic access as separate paths.
- Station context: Apply the module only within the documented OIS20, OIS25 or MCS arrangement.
- Configuration backup: Retain the accepted hardware setup in the maintenance record for future exchange.
- Operator keyboards: Interfaces the primary and secondary keyboard paths for the operator station.
- Event printing: Connects the station to its documented printer channels.
- Service terminals: Provides the assigned diagnostic-terminal interface.
- Legacy OIS maintenance: Restores serial peripheral communication in supported Bailey station arrangements.
