Wiring Example

1. Modbus RTU Version

This wiring example shows that the device is connected to a computer via a USB to RS485 converter. Running a serial debugging software on computer, users can debug and test the device easily before applying it to a control system. When it is connected to a PLC or an industrial controller, in the same way, the yellow wire from the siren is connected to the RS485 communication port A (+) of the PLC/industrial controller, while the green wire is connected to the RS485 communication port B (-).

2. One Trigger Input (Button) Version

Notes:

1. The yellow wire is the trigger input terminal and the green wire comes from the ground.

2. The yellow wire also can be connected to a PLC or an industrial controller, which outputs a low level signal to trigger the player. The PLC/industrial controller needs to share the same ground with the player first.
