** Request Measurement Register
Writing this register acts like the SDI-12 command aM0!
Reading this register returns the # of seconds since the last Refresh (i.e. the age of Data Available).
Note that immediately after a Manual Refresh to register 401, a Read returns a negative number
indicating the # of seconds to wait for new data.
SDI-12 Mode and Modbus Mode Operation setting
In Modbus mode - Auto Refresh = nn secs (
Modbus register 0101)
Write any value to Modbus register 401 will returns zero (0). Data Available
In SDI-12 Mode, Auto Refresh = 0 secs (
Modbus register 0101 OR Set via PC Utility SONIC)
Velocity Trace
To implement current TTL serial function over RS485 using same command and same data format.
