KDU — Printer Accessory

The KDU (keyboard display unit) is a small terminal unit that interfaces with the printer for

accessing EPL label forms stored in the printer.

The KDU is strictly a terminal and does not have the capability to store data or set up

parameters. The KDU is used for the following functions:

• List label forms stored in printer

• Retrieve label forms stored in printer

• Input variable data

• Printing labels

The KDU was designed for Zebra EPL printers. The EPL printer’s serial port was configured

for DCE (data communication equipment) communications configuration. The G-Series

printer has a DTE (data terminal equipment) serial port configuration. Because of the KDU

and G-Series have different wiring configurations, a KDU serial port adapter is needed to

properly supply power to the KDU and enable communications between them.
