Reader Installation Guide
This section contains information for configuring the Reader’s power and signal cabling. Power
and communications are provided through supplied two phoenix plugs (one 8-pin and one 10-
pin) that you can remove from the PCBA, attach your wires, then reinsert the plugs to the
connectors.
Mounting
The mounting bracket is designed specifically for mounting the
tres900s
Reader. The Reader
could be installed on a pole or on wood, concrete, or brick structures and aim the antenna toward
zone of coverage. Figure 7 below shows how the bracket looks assembled on a pole. The tool
of choice would be a 3/8” (10 cm) wrench.
