KDU — Printer Accessory
6/4/08 GX420d User Guide 980611-001 Rev. B
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.
