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 |
