The Keyboard Display Unit (KDU) is a terminal unit that interfaces
with UBI EasyCoder 71 in a stand-alone capacity.
The KDU has sixty-two (62) keys and a 2-line, 20 character LCD
display. The KDU is powered by and communicates with the
printer through an RS 232C port. The KDU has an auxiliary
RS 232C port for input only, i.e., from a scanning device, magnetic
stripe reader, scale, etc. The KDU pr5V to the auxiliary
port.
The KDU is strictly 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 stored label forms.
• Input variable data.
• Print label.

protocol, e.g. by issuing a U command (see page 46) or entering the
Test Mode (see page 11):
Baud rate 9600, Parity none, Data bits 8, Stop bits 1.
If not, reset the communication parameters using a Y command, see
page 41.
Switch the printer power to OFF and connect the KDU's 9-pin
connector to the printer's serial port, then switch power ON.
