RTU/TRM-710 compatibility mode
If the compatibility mode is set to "On", the RTU-810/TRM-810 will behave like an old
RTU/TRM-710 device in some parts for compatibility:
The radio RSSI in the MODBUS register 1 and in the "*"-commands in the
serial "ZZ" mode will be returned in an uncalibrated "%"-Value instead of a
calibrated –dBm value
The device ID will not be 0x0800 to indicate it's an RTU-810, it's instead
reporting the old ID from the 710-series:
RTU-810/DA1
0x0011 (RTU-710/DA1)
RTU-810/DA2
0x0010 (RTU-710/DA2)
RTU-810/DA3
0x0012 (RTU-710/DA3)
RTU-810/DA4
0x0013 (RTU-710/DA4)
RTU-810/DA5
0x0014 (RTU-710/DA5)
TRM-810
0x0028 (TRM-710/S1U)
The status register has the old behavior of the 710 series, that any write to this
register clears all bits of the register. Normally for the RTU-810 only bits which
are set in the write access will be cleared.
