The Loxone Modbus Air is designed to integrate a device with Modbus RTU interface.
Table of Contents
Mounting↑
Connect the power supply and the Modbus A/B data lines:
If the Modbus device to be connected provides a suitable voltage output, no separate power supply is required:
Only one Modbus device can be connected, the enclosed connection cable must not be extended.
For best reception, the device has to be placed outside of metal covers.
Commissioning↑
In delivery state, pairing mode will be active after the power supply has been established. This is indicated by the status LED flashing red/green/orange.
Then follow the pairing procedure on the Air Interface.
To activate the pairing mode manually, switch off the power for 10 seconds, then switch it back on. If no connection to a Miniserver can be established for two minutes, then pairing mode is activated for 5 minutes.
Programming↑
From the Loxone Library a suitable template for the integration of devices can be imported.

Communication with Modbus RTU
Only the values that are actually sent to the Miniserver are displayed in the Modbus Monitor.
This means that only values that have changed are shown. The data is not displayed in the monitor during every polling cycle.
