Connection cable The data transmission line for the gas detectors working in the RS-485 standard should be performed only with the use of a shielded twisted pair cable.
- Page 58 www.atestgaz.pl Power supply of the gas detector As a standard, in gas detectors with digital data transmission, it is assumed that the voltage cannot drop below 12 V (see the documentation of the detector). The power consumption of the detector is constant within the range of acceptable voltages.
