EXT CONNECTOR

The EXT connector on the rear panel of the “S” printers is intended for use with the

external printer accessories such as label rewinders or applicators. The DB-9S type

connector provides a choice of four different output signals along with various error

conditions.

Pin Assignments

PIN DIRECTION SIGNAL DESCRIPTION

1 To Host Vcc - +5V

2 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.

3 To Host Error - This pin goes low when the printer detects an error

condition such as head open or receiving buffer full.

4 To Printer Reprint - The last label 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.

7 To Host Label Out - This pin goes low (0V) when a label out error exists.

8 To Host Ribbon Out - This pin goes low when the ribbon is out.

9 Reference Signal Ground

NOTE: The signals on pins 2, 3, 6, 7 and 8 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 330 ohm, 1/4W pull-up resistor between the open collector output pin and Vcc (pin 1) as

illustrated . This will provide a signal level of +5V for a true condition and 0V when a false condition exists. The maxi-

mum voltage that can be applied to these pins is +50V and the maximum current they can sink is 500 milliamps.
