1.2 Notes on Setting Parameters
This section describes the setting parameters for using the communication functions and their setting
ranges.
NOTE
The details of UT150L communication functions need to be the same as those of the communication
functions of the host devices to be connected. Check the communication parameters of the host device
first, then set up those of the UT150L.

Baud rate
Note 1: When “3: ASCII mode” is selected for MODBUS communication in protocol selection, the data length is fixed to “7.”
When
“4: RTU mode” is selected, it is fixed to “8.”

Communication Protocol
●
Protocol selection (PSL)
Set the same communication protocol as that of the host device to be connected. The UT150L has PC
link communication, and MODBUS communication functions.
