APRS telemetry

[mooks]

I am using a new Argent Data OTM-3 . The telemetry reports 12.9 battery voltage. The byte value is reported as 521. The manual says that it reports in 1/10V and maximum is 20V and the byte value is 1-256. I don't understand why the value is 521 and from that how it gets a voltage of 12.9.
Telemetry also says the equation values are 0,1,0. How can it report 1/10V with an equation of 0,1,0 shouldn't it be 0,0.1,0 ?
An explanation so I can figure it out would be appreciated.
thanks

Have you asked Argent Data?

I checked the website and read the Wiki.... although it made sense for the examples they gave,
doesn't seem to work with the data I am getting.

Have you called or emailed Argent Data?

Are we sure the telemetry data contains the battery voltage?

From looking at your log, I see what appears to be voltage and temperature reported in the comment section of a position packet.

The third line in the above log is a position packet, which is indicated with an exclamation point as the data type indicator.
