Electrical requirements

•Supply voltage (optional):10 - 40 V d.c.

•Current consumption:< 50 mA @ 40 V

The Data Communication board includes a 10-pole and two 20-pole ‘Micromatch’ flat-cable connectors (female) and a 9-pin D-type connector (male) for serial data output.

The pin configuration is of the D-type is shown below:

9.	Parallel output connector via 20 solder pads (open collector outputs).
10.	Initialization button with LED indicator to indicate the none initialized mode.
11.	Parallel output connector 20-pole Micro-Match connector.
12.	10-pole Micro-Match connector for the external power supply. Initialization status output and
	initialization button.
13.	2-pole external power supply connector (2-solder pads) and a 2-pole screw connector.
14.	2 m (6.5 ft.) long cable terminated with a 6-pole circular connector for connection to the DCN
