DigitalFlow™ XGS868i Programming Manual
Notes:
1.
1.
Clear Totalizers: f
lag from the 8051 to clear either the Channel 1 or Channel 2 totalizers.
2.
MODBUS baud rate: 5
= 2400, 6 = 4800, 7 = 9600
3.
MODBUS parity: 0
= none, 1 = odd, 2 = even
4.
MODBUS stop bits: 1
= 1 stop bit, 2 = 2 stop bits
5.
AVG Error Code:
0=Both Ch1 and Ch2 are in error.
1=Ch1 only is in error
2=Ch2 only is in error
3=Both channels are error free
