13.1 I/O Connector

All I/O and power supply terminations on the V1.1 PCB are via 2.5mm (0.1”) screw terminals provided on a 12-way pluggable connector. This connector is positioned on the right hand side of the iRIS 320 circuit board, directly above the white battery connector. On the iRIS 220, the connector protrudes through the top of the case.

The function of each I/O termination is shown in the diagram below.

	VIN+	15-30Vdc External Power Supply (Charger Input) +
	GND (-)	0Vdc External Power Supply (Charger Input) -

BOTTOM

NOTE: The terminal marked 12V- is bonded to the other GND terminals and on the Revision 1.2 PCB is marked as such.
