PC/104-Plus Octal Serial Communication Interface (OSCI)

The OSCI module is a PC104+ Card that provides 8 free selectable serial interfaces, either RS232 or RS485 / RS422 - interface , to any PC/104-Plus system. There are 2 standard variants of the OSCI module available:

OSCI-8MIX:
Standard PC104+ card for all PC104+ compatible PCs. 8 free selectable RS232 or RS485 full or half duplex interfaces. Two self configurable interface cables are included to connecting the on board headers to standard D-SUB 9 pin connectors.

OSCI-6MIX2G:
Standard PC104+ card for all PC104+ compatible PCs. 6 free selectable RS232 or RS485 full or half duplex interfaces. Galvanic isolation (500Vrms) on the first 2 serial interfaces (interfaces used as RS485 / RS422). Two self configurable interface cables are included to connecting the on board headers to standard D-SUB 9 pin connectors.
