Developed by the Landis & Gyr company, the telecontrol protocol Telegyr 709 enables
the coupling of control stations to Telegyr 709 substations.
There are two protocol variants:
- Telegyr 709
which uses the proprietary PCM (Pulse Code Modulation) format to encode data as 60-bit words with a 16-bit checksum.
- Telegyr 709 USART
which uses the asynchronous standard format with start bit, data bits, parity
and stop bit for data encoding.
