PWR connector: This is a standard 2.5mm plug connection. The unit’s power supply is
12-15 volts DC with a minimum rating of 250 mADC. Upon application of power from
the 2.5mm PWR connector or by the RS-232-B Pin 6, the 10/100 and Status LED’s will
either blink or become illuminated solid. Refer to Section 2.2 for a description of the LED
functions.
