Barix X8
The X8 is a universal I/O device, suitable to interface analog, digital signals and specialty sensors such like Dallas Onewire Temperature Sensors (Barix TS) or Access Control readers with wiegand interface to an RS485 bus. The bus protocol is Modbus/RTU.

How to wire Barix TS to the X8
The X8 supports up to 8 temperature sensors, one per input. The sensors are autodetected, no need to configure these. However, the corresponding I/O bits must be configured as INPUTS for the sensors to be detected. If you only need the X8 for a couple of I/O and one temperature sensor (as it would typically be the case in a light switch), you can wire the temperature sensor to input pins and program the I/O connected to the "ground" wire of the temperature sensor as output with value 0. Example:
If a Barix TS is connected between I/O 7 (ground wire) and I/O 8 (data wire), I/O 7 needs to be programmed as output and default 0. Of course, if the Barix TS is connected between any I/O pin and ground, no programming is required.
