RS485 Echo (RS485Echo)


It works on: all devices

Prerequisites: you should connect a RS485 repeater on your RS485 board connector.

In this example a board works as repeater. If you sent data, the board collect it and sends it back to RS485 device. For this example we connect our USB RS485 Isolated Converter V3 to the board and use Hercules SETUP utility for a test software.

RS485 Relay (RS485Relay)


It works on: all devices

Prerequisites: you should connect a RS485 device on your RS485 board connector.

Here you can manage relay on the board through RS485 protocol. Get or set it status. With this functionality you can simple to scale your project if you needed more relays for example. We created a simple protocol:

  • FFR - Get relays status
  • FFR0000 - Set all relays to Off
  • FFR0101 - Set relay 1 and 3 to On
  • FFR1111 - Set all relays to On
  • FFRx1xx - Set only relay 2 to On, other relays keep it status
