Makes it possible to convert the INTRABUS signal into an RS-485 MODBUS signal (with INTRABUS communication protocol), to allow
connecting cables device-user interface up to 1,000 m.

Configuration upload
1. Place micro-switch 1, 2 and 3 of the three-positions DIP in position ON and micro-switch 1 and 2 of the two-positions DIP in

3. Connect the device to the INTRABUS port of the controller as shown in the section ELECTRICAL CONNECTION, or:
- connect terminal 1 to terminal “12 V”
- connect terminal 2 to terminal “data INTRABUS”
- connect terminal 3 to terminal “reference (GND)”.
4. Power up the controller; see the relative instruction sheet.
The recognizing of the device will be run.
The recognizing normally takes a few seconds, when it is finished the green LED and the red LED will firmly switch on.
