Description
The M442R module is a low-cost integrated module which offers the chance of expanding the communication possibilities of a PC/104 based system.
The M442R module integrates 4 serial ports: two of them are RS-232C standard serial ports in a Full Modem configuration. The other two ports can be settled to work also in RS-232C Full Modem mode, or in a RS-422 or RS-485 mode.
Addresses of the serial ports are default settled as standard COMs, but are user re-mappable in the I/O space.
IRQ lines of serial ports are individually configurable.
