ACCESSORY (EXT) CONNECTOR

The Accessory (or EXT) connector on the M-8400RV printer rear panel 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.

SIGNAL DESCRIPTION

 

 

 

 

 

 

1

To Host

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

 

 

 

2

Reference

Signal Ground

 

 

 

3

To Host

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

 

 

 

4

To Host

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

 

 

condition such as head open or receiving buffer full.

 

 

 

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 ON 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 Printer

Print Repeat - The printer repeatedly prints the current label in

 

 

the print buffer immediately after receiving this signal.

 

 

 

10

To Host

+12V - Used to power accessory items.

 

 

 

12

To Host

+24V - Used to power accessory items

 

 

 

13

To Host

Vcc - +5V

Frame Ground

 

 

 

 

 

 

NOTE: The signals on pins 1, 3, 4 and 6 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 1K 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 maxi- mum voltage that can be applied to these pins is +50V and the maximum current they can sink is 500 milliamps.
