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.
