Appendix

What to do if RS-485 connection fails?

When a reader successfully connects to GV-AS Controller via RS-485, the Controller's Web interface should show a green tick under Connection Status, and the reader's LED should switch off from a continuous red.

If the reader's LED remains red and there is no successful connection status on the Web interface, try adding a 180 Ohms terminal resistor on the RS-485 terminal block of the reader to extend the range of data communication.
