Section 6. Interface Specifications
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

signals
along
with
various
error
conditions.
A

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: Thesignals on pins1,3,4,6,9 and10 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 signal level of +5V, you must add a 330ohm,1/4Wpull-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 500milliamps.
