Figure 3-2 Specifying Broadcast
The broadcast function enables all of the connected UT150L or other devices to receive a command.
Specifying an address number in Table 3-3 for the address number column in a command enables the
host device to write data from/into the internal registers of all UT150L or other devices.
For UT150L, internal registers (D registers and I relays) are assigned with numbers for management.
(See chapters 5 and 6 for details.) For the internal registers of other models, see the documentation of
the relevant model.
