6.2 Powering the COM310 Modem
Newer Campbell Scientific dataloggers provide 12 VDC on CS I/O connector
pin 8 for powering peripherals such as the COM310. The alternative, if you
have a dataloggers/wiring panel lacking 12 VDC on pin 8, is to wire the green
connector on the side of the COM310 to the data12 VDC and power
ground terminals (refer to Figure 4). The COM310 comes with a mating green
power connector for this purpose. The following Campbell Scientific
dataloggers lack 12 VDC power on CS I/O pin 8.
