The MPL4431 is a board which routes a 10 pin flat cable with a MPL specific pinout to two DB25 connectors. The flat cable connector is compatible with the MPL4080, MPL4080B, MPL4082 and the MPL4215 pinout. The print is mounted on an aluminum front plate for direct mounting into a 19¨ rack. A few jumpers make it possible to change RxD and TxD as well as RTS and CTS so that it will behave as a terminal or a computer.
