[Sync/Async Optical Modem] FRM220-DATA Series

Extending V.35/RS-232/RS-530/X.21/RS-449 with optical cables.

The system can be used with full-duplex/half-duplex communication methods for control systems and supports both synchronous and asynchronous communication. Regardless of the external metal side (device side) interface, the optical modem itself comes with a standard HD-26 connector interface, and dedicated connector attachments compatible with V.35/RS-232/R530/X.21/RS449 interfaces are included. Settings such as communication speed and communication method can be changed using the built-in DIP switches.
