Chapter 1 Setup
●
Address number (ADR)
Set the address number of the UT150L itself. An address number of 1 to 99 may be assigned in any
order. There is however one limitation — the number of UT150L to be connected to a single commu-
nication port is limited to 31.
Example of connecting four UT150L to a host device by setting address numbers of 1, 50, 10, and 20
ADR=1 ADR=10
Maximum overall cable length of 1200 m for a maximum of 31 substations
ADR=20 ADR=50

●
Baud rate (BPS)
Set the same communication rate as that of the host device to be connected. (Otherwise, proper
communication cannot be achieved.) The unit of the communication rate is bps (bits per second).
●
Parity (PRI)
Set the handling of parity to be carried out when data is sent or received. Set the same parity state as
that of the host device to be connected.
●
Stop bit (STP)
Set the same stop bit as that of the host device to be connected.
●
Data length (DLN)
Set the same data length as that of the host device to be connected. (When MODBUS communication
(PSL: 3 or 4) is chosen in protocol selection, the data length is fixed.)
