The EMIO-3210, an Em-IO expansion module designed for kiosk applications, is good for the system that needs multiple COM ports and high bandwidth. It supports six serial ports (six RS-232/422/485 ports, configurable in BIOS setup) and two IEEE 1284 parallel ports. A system with the combination of an EITX-3000 board and an EMIO-3210 can support 10 serial ports and two parallel ports!
