Designed for interfacing EDGE EVO Hi-O interface to a traditional Wiegand reader, the Reader Module provides Wiegand and typical
reader I/O. Congure the module in two ways, either a Group 1 or Group 2 device. When two readers are present at one access control
point, the secure reader side is assigned Group 1. The internal iCLASS reader within an EDGE EVO Standard Reader/Controller is always
assigned Group 2.

jumper.
Reader Tamper
The Reader Tamper + and - are implemented allowing a connection for an open collector external tamper from a reader, such
as iCLASS.
Note: Connect P3, Pin 2 (GND) from the Reader Interface Board to the same ground as the reader power, if the reader is not
