Description

The MICROSPACE module MSMR104 is based on SMC’s

“Fast Serial Port Super I/O” controller FDC 37C664. The

board integrates two serial interfaces and one bi-directional

parallel interface.

The serial controller is configured as COM3 and COM4 with

selectable interrupts. The interrupts are: IRQ 3, 4, 10, 11.

COM3 and COM4 are individually selectable by jumpers as

RS232C or RS485. The LPT2 parallel interface can be

used in a bi-directional way. For most operating systems, a

wide range of drivers is available.
