The 'EXPANSION' connector on the rear of LabSat 3 gives access to a number of signals including CAN Bus, RS232, 1PPS and Digital input/output. Accessory RLACS202 is used to provide user signal access for integration into the users test system. Pin functions are as follows:-

Number	Name	I/O	Function
1	1PPS	O	Signal from Internal GNSS monitor. Becomes active when monitor is locked. 5 V Level. 25 mA
2	DIGO	O	User digital output. 5 V Level. 25 mA max
3	DIGI	I	User digital input. Up to 12 V input level. Detection threshold=2.5 V
