The MS-PWR is not a sensor, but is included here because of its close relationship with the sensor products. Instead, this device enables the user to inject external power into the 1-Wire® network when the serial port power is not enough to drive the network.
However, the MS-PWR is NOT a power supply. It will facilitate the use of an external source that is capable of supplying 12 VCD to a 2.5 mm coaxial connector, negative to center post. For operation in the USA and other North American counties, the HubPwr device can be used.
CAUTION: The MS-PWR must be connected as the first device on the network so it is the closest to the master interface. Failure to do so can result in faulty readings and, in extreme cases, damage to the serial port circuitry.
