Data reception
Data is received in serial asynchronous form in accordance with the standard referenced in IEC
61162-2.
The following parameters are used:
• Baud rate
Input: 38,400 bps, IEC 61162-2-1, 4800 bps, IEC 61162-1-2
Output: Same as above. Baud rate fixed at 38400 bps for DS-600.
• Data bits: 8 (D7 = 0), Parity: none, Stop bits: 1
Data sentences: Input
Data format is IEC 61162-1 Edition 3 unless noted otherwise.
