12. mperature measurement is made with a DS 2438Z The device is not calibrated but empirical data shows it to be accurate within a few degrees of actual with an operating range of 40 to 85 degrees C Because the sensing device is partially enclosed and mounted to the PCB the response time to temperature changes will relatively slow Care should be taken not to place the sensor in direct sunlight as the radiant heat will be partially trapped inside the enclosure and cause readings higher than ambient MultiSensors like all 1 Wire slaves can operate on parasitic power That is they use the power contained in data signal of the 1 Wire bus with a capacitor to sustain them during the zeros Unlike most other 1 Wire devices MultiSensors have an AUX jumper This jumper connects the Vcc line on the sensor directly to the power source of the serial port via the master Link thus providing a constant Vcc to the sensor independent of what the line signal doing The AUX jumper is set to provide Vcc when shipped from the factory NOTE If the AUX line of the master Link is being used for another purpose the jumper on the sensor must be removed The number of devices that can be connected to a particular 1 Wire network will vary a great deal depending on the capabilities of the serial port supplying the network Typically ten to fifteen devices can be supported without additional external power If additional power is required due to a
