Wiring Example for Multiple Devices

If you need to control multiple devices, you can refer to the parallel wiring example as below.

This wiring example shows that the devices are connected to a computer via a USB to RS485 converter. The yellow wire is for connecting the RS485 communication port A (+) from computer to the devices, while the green wire is for connecting the RS485 communication port B (-) from computer to the devices. Running a serial debugging software on computer, users can debug and test the device easily before applying it.
