5. Configuration
To install the module, follow the steps below:
1. Connect the thermistor analog input.
2. Connect the module to the RS-485 network using the DATA+ and DATA- terminals. If
the host is only equipped with an RS-232 interface, then an RS-232 to RS-485
converter will be required.
3. Connect the module to the power supply using the +Vs and GND terminals. Note that
the voltage supplied should be in the range of +10 to +30V DC.
4. Open DCON utility pro
click on COM port(first icon).
It can select multi-options such as Baud Rate, Protocol, Checksum, and Format to
search module. The default settings for the module can be found in Section 3. Click OK
after selecting the COM port setting.
