3 Power Connections
The wall adapter should be plugged into a standard 120 VAC outlet. When
powered, the TXD and RXD indicators should come on. As data is passed through
the converter, the lights will flicker.
-NOPWR (No Power) Option
A COM32 with the -NOPWR option must be powered by an external source rated
between 7VDC and 12VDC. It is recommended that a power supply adapter with
an output of 9VDEC at 500mA be used. The COM32 with this option is supplied
with a pair of leads with spade connector terminations which extend form the side
of the enclosure (see Figure 3.1.1).
Figure 3.1.1 -NOPWR Option
-UNI Option
The -UNI option is a universal power supply that allows the COM32 to be powered
from any standard international voltage and frequency. Refer to Figure 3.1.4 for
more information.
The “table-top” design of the supply allows it to be positioned a top any flat
surface. A standard IEC 3-pin socket is provided for connection of an appropriate
power cord (not supplied) to match the configuration of the power outlet. The
supply is permanently connected to the COM32.
