Configuration

Download the software from eyc-tech official website, decompress it and execute it. Planning software operating system requirements: Windows XP SP2 or above.

1. Hardware connection: Connect the THG03 / THR23 / GS23 to PC through USB to RS-485 or RS 232 to RS-485 cenverter

2. Check the COM port number from Device Manager in Computer Management. e.g. COM1in illustration
   

3. Open the Ul, go to function ” Interface” , clickitem ” Config” and then setting COM port, BAUD rate, data format and Station ID, pressed ” Apply” for connection
   

4. Scan RS-485 connection
   Open the U, go to function ” Interface” , clickitem ” Config” and then setting COM port, pressed ” Scan” bottom for scan devices and pressed ” Close and Export ” when the interested devices found.
   Pick up the device that you want to connect to and then press “Apply” to go.
