Print Trigger 1 Connector
The printer provides a 12V 200 mA DC total output for use by a photoelectric Cell (Pec), inductive proximity
detector or micro switch. The pin allocation of the print trigger 1 connector (Figure 21 (
4
)) is as follows:
Pin Function
DIN Pin 1 +5V DC supply to sensor.
DIN Pin 2 Sensor output.
DIN Pin 3 0V DC common.
Shaft Encoder Connector
The printer provides a 12 V (200 mA DC total) output for use by a shaft encoder with a maximum frequency of
100 kHz. The pin allocation of the shaft encoder connector (Figure 21 (
5
)) is as follows:
Pin Function
DIN Pin 1 +12 V DC supply to shaft encoder.
DIN Pin 2 Shaft encoder output “A”.
DIN Pin 3 Shaft encoder output “B”.
Din Pin 4 0V DC common.
Note: The shaft encoder output must of the PUSH/PULL type.
COMM 1 Connector
The printer has an RS232 communication port linked to the COMM1 connector (Figure 21 (
6
)) the pin allocation
is as follows:
Pin Function
DIN Pin 1 0VDC common
DIN Pin 2 Transmit data out from the printer.
DIN Pin 3 Received data into the printer.
Din Pin 4 DTR output from the printer.
Din Pin 5 DCD input to the printer.
Status O/P Connector
The printer provides an output for a set of status traffic lights via the STATUS O/P connector. The pin allocation
of the connector (Figure 21 (
7
)) is as follows:
Pin Function
Din Pin 1 Red lamp negative supply.
Din Pin 2 Amber lamp negative supply.
DIN Pin 3 Green lamp negative supply.
Din Pin 4 +24V DC supply to the strobe/siren.
Din Pin 5 Strobe/siren negative supply.
DIN Pin 6 +24V DC common to the traffic lights.
