Keyboard wedge PS2 interface
(for older computers that have a PS2 keyboard and only one PS2 connector into which BOTH the keyboard AND the scanner need to be connected)

RS232-DB9 serial interface
(this is for devices that are expecting serial data streams rather than keyboard data. NOTE: To get serial communications working, you will have to match a number of set-up parameters on both the scanner and the device that it is communicating with - parameters such as the number of data bits, the number of stop bits, the parity and the communication speed (BAUD rate). NOTE: RS232 serial scanners generally also require a 5 volt power supply which may or may not be included in scanner price, so check the Product Description very carefully before ordering)
