After testing attach one label to the reader and for decorative purposes, another label on the other side of
the glass.
If the reader is to be mounted directly on to the door or wall, a hole 45mm diameter, and at least 10mm
deep should be drilled at the centre of the desired reader position. An additional hole will also be needed
to bring in the cabling to the reader.
Connections
The connections are shown above.
The power supply to the reader (between 0V and V+) should be between 5V and 18V d.c.. The current
consumption of the reader is approximately 60mA, so voltage drop in the cable should be considered but
will rarely be a problem.
The connections marked “Hi”, “Range” and “Lo” (terminals 3 to 5) allow the reading range to be
adjusted. If Range is linked to Hi the reader will give full range, while connecting Range to Lo reduces
the range to approximately 60%. Do not leave these unconnected, and do not connect them to anywhere
