EXT CONNECTOR
The EXT connector on the rear panel of the “Se” printers is intended for use with the
external printer accessories such as label rewinders or applicators. The 14-pin
Centronics type connector provides a choice of four different output signals along
with various error conditions. A DB-9 to 14-pin Centronics adapter cable is provided
for legacy applications.

PIN DIRECTION SIGNAL DESCRIPTION
13 To Host Vcc - +5V
10 To Host Ribbon Near End - This pin goes high when the amount of ribbon
on the unwind shaft is approximately 46 feet (14 m). The output
will be low when the ribon is completely out.
4 To Host Error - This pin goes low when the printer detects an error
condition such as head open or receiving buffer full.
7 To Printer Reprint - A duplicate of the last label in a print job will be
reprinted when this signal is received.
5 To Printer Print Start - The printer will print one label when this pin is pulled
to ground. This signal must be enabled by placing switch
DSW3-5 on the Control Panel in the OFF position.
6 To Host End Print - It is used to drive an applicator or other external
device requiring synchronization with the print cycle. You may
choose between four types of output signals using control panel
DSW3-6 and DSW3-7 selections.See timing charts on next page.
1 To Host Label Out - This pin goes low (0V) when a label out error exists.
3 To Host Ribbon Out - This pin goes low (0V) when the ribbon is out.
2 Reference Signal Ground
8 To Printer Reserved
9 To Host Off Line - This pin goes low (0V) when the printer if Off Line.
Note: This conditions that determine when this line goes true can
be modified by the LCD Service Mode Panel setting
11 Reserved
12 To Host +24V +/- 10% @2A - Power for external devices.
14 Frame Ground
NOTE: The signals on pins 1, 3, 4, 6, 9 and 10 each have an open collector output. These pins normally measure
+.07V maximum when a true condition exists. If a false condition occurs, the voltage will drop to 0V. To achieve a sig-
nal level of +5V, you must add a 330 ohm, 1/4W pull-up resistor between the open collector output pin and Vcc (pin
13) as illustrated . This will provide a signal level of +5V for a true condition and 0V when a false condition exists. The
maximum voltage that can be applied to these pins is +50V and the maximum current they can sink is 500 milliamps.
