1.4 Power Control
The COM9522B will be used to control power to the modem with the use of
5 Vdc trigger on a datalogger control port (ex. C1: yellow wire). It is possible
to power the modem from the datalogger; however, it is recommended that a
separate power source be used for the modem to avoid catastrophic loss of data
in case of power failure. The COM9522B must draw power directly from a
12 Vdc power supply (power +: Red, ground/power –: Black).
