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 five minutes, pairing mode will be activated for a limited time.
Programming↑
From the Loxone Library suitable templates for the integration of devices can be imported.
