19.6.3 Address Configuration
UMB Device-ID and SDI-12 Address are connected, but the different address ranges and the
fact, that UMB ID’s are integer numbers, while SDI-12 addresses are ASCII characters, have
to be considered.
The SDI-12 address is built from the UMB device ID as follows:
UMB Device ID 1 (default) corresponds to SDI-12 Address ‘0’ (SDI-12 default).
Changing the SDI12 address by SDI12 setting command also modifies the UMB device ID
accordingly.
Valid Address Ranges:
UMB (dec)
SDI-12 (ASCII)
