The “W3ADO” indicates that the telemetry
packet comes from the A side.
The next distinction for each packet is the cycle count. There are four cycles for each side. Each designated by a 03 binary code (00,01,10,11). These two digits are located on the last two digits of the second to last number separated by commas as shown below.
The “01” indicates that this is telemetry cycle 01.
The
four values that correspond to the telemetry values are those located directly
after the telemetry count (which is represented by T#XXX). On the telemetry packet above, the four
telemetry values are “132,138,159,131.”
The fifth value is a constant, which represents the 5V reference. The
table below identifies the location of each value.

The
following table gives the unit conversion equations for each of the
telemetry values as to the coefficients
of a general CUBIC equation of the form Ax^3 + Bx^2 + Cx + D where X is the raw
value in the packet.
