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.
