Cause

Need for proper configuration and connection method to communicate with the controller using NCP Palm.

Resolution

Using the IR Tool:

1. Connect the IR Tool to both your laptop and the Unifact Pro controller.

2. Launch the NCP Palm program.

3. In the program:

   • Select the correct serial communication port.
   • Uncheck the CTS / RTS selection boxes.
   • Click OK.

     

     

4. From the File menu, select Connect.

   • Enter Subnet Address: 0
   • Enter Node Address: 0
   • Click OK
     

     

     ✅ You are now connected to the IR Tool.

     

5. To connect to the controller:

   • Go to File > Disconnect
   • Then go to File > Connect
   • Enter Subnet Address: 1
   • Enter Node Address: 1
   • Click OK

     

     ✅ You are now connected to the controller

Using the RS-232/485 Converter:

• The process is similar to the IR Tool method.
• Instead of using the IR Tool, connect directly to the controller’s communication terminals via the RS-232/485 converter.
