Data transmission

Data is transmitted in serial asynchronous form in accordance with the standard referenced

in 2.1 of IEC 61162-1. The first bit is a start bit and is followed by data bits,

least-significant-bit as illustrated below.

The following parameters are used:

Baud rate: 4800

Data bits: 8 (D7 = 0), parity none

Stop bits: 1
