Data transmission
Data is transmitted in serial asynchronous form in accordance with the standard referenced in 2.1
of IEC 61162-1/2. The first bit is a start bit and is followed by data bits, least-significant-bit as il-
lustrated below.
The following parameters are used:
Baud rate: 38.4 Kbps /4800 bps
Data bits: 8 (D7 = 0), parity none
Stop bits: 1
