Because the utilizes a single external power connection for both control power and MDR power; the includes internal re-settable fusing to protect the control power from the MDR power. The overall control power fuse is rated at 300 mA and this is the source for CPU, LED’s, sensor ports, control ports, etc. From this circuit, the Sensor and Control port pairs share their own separate 100 mA fuses.
!User’s must take care in the types of sensors and devices that need to connect to a given and assure that the current draw on any Sensor/Control port pair does not exceed the fuse ratings. If any of the 100 mA fuses trips, there is no direct indication of this state. An indirect indication could be to see if a connected sensor is powered when plugged into either port.
!If the 300 mA fuse trips, upon the automatic reset of the fuse, the should reboot on its own. However, the may require the power to be cycled manually to fully restart
