Data lines for LDS should be documented

[griswaldbrooks]

Use Case

In order to get data from the LDS, the required data lines need to be identified.

Acceptance Criteria

GIVEN Gen1 and Gen2 LDS
WHEN wanting to connect to the LDS to get data
THEN the required data lines should be reference-able in a wiki document.

Dev Notes

The dataline for the Gen1 LDS are readily identifiable because the connector is broken out, though, which is RX and which is TX is not documented.
It is possible, some information here might be helpful.
During an initial SPIKE, it was identified that the differential comparator for the data circuits on both LDS are the same (LM393A) so it is likely that a comparative analysis of the two interface board would identify the TX/RX lines.
Alternatively, powering the circuit and identifying the lines which are streaming data, might be required.
