Keyboard Ports
Two keyboard connectors are provided. One is an IBM PS/2
standard, 5-pin mini-DIN connector. This connector accepts an
optional traditional ASCII keyboard. Wedge-type barcode
scanners should be connected to this port; the (optional) key-
board should then be plugged into the barcode scanner.

The second keyboard port is a 4-pin locking connector. It is
typically used in mobile applications where movement and
vibration would require a more robust connection than the
standard connector can provide.
