Operational Modes

980548-001 Rev. A KDU Plus User’s Manual 6/12/06

FORMS MODE - This is the KDU Plus default operating mode. When the Auto-Detect is

enabled, the KDU Plus will try to establish EPL communication and then ZPL

communication. The KDU Plus will count down 60 seconds while continuing to establish

Forms mode operations before initiating Terminal Mode with the serial port set to DTE

communication. If the KDU Plus fails to establish Form Mode operation, then the KDU Plus

will default to Terminal mode.

The CONNECTION status line in the illustration of the Forms Mode screen will show the

printer’s language (EPL or ZPL) and the serial interface (DTE or DCE) or it can have a ‘No

response from printer’ status. If the KDU Plus is forced to one of the Form Modes and Auto-

Detect is turned off, the KDU Plus may report on the CONNECTION status line a ‘No

response from printer’ status.

TERMINAL MODE - This is the default mode when the KDU Plus can not communicate

with the printer. Use the Setup mode to change the PRINTER/COM port to DCE

communication for EPL printer communication and other serial port communication

parameters. This mode is used primarily for debugging purposes.

FILE MODE - File Mode must be selected using the Setup Mode. The KDU Plus can startup

in File Mode by turning off Auto-Detect and setting the operational mode to File Mode. Files

can be transferred (for processing by the printer) from a PC (host computer) to the KDU Plus

and from the KDU Plus to a Zebra printer using serial port communications.

File Mode can be used to manage printers by sending files with commands for immediate

processing or files that store Forms in the printer for later retrieval in Forms Mode.
