The PNL9M16, 16-inch IDC Serial to Panel Mount Serial Cable, features a 10-pin (IDC) motherboard header connection on one end and a panel mount DB9 male connector port on the other - a simple answer for adding a DB9 (RS232) serial port to any computer system which has an RS232 serial panel mount receptacle. This cost-effective solution bridges the compatibility gap between modern computers and legacy serial peripherals.
