EXT CONNECTOR

The EXT connector on the rear panel of the CL Series “e” 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.

Pin Assignments

PIN DIRECTION SIGNAL DESCRIPTION
13 To Host Vcc- +5V
10 To Host RibbonNear 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.
11 Reserved
12 To Host +24V+/- 10% @2A - Power for external devices.
14 Frame Ground

Section 6. Interface Specifications
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.
