else. (Leaving Range open circuit will give an intermediate reading range, but there is a danger that
reading will be unreliable.)
The green LED will light when the LED input is grounded.
Readers can be configured as either Wiegand output or Clock/Data output. The same data connections
are used, as shown in the drawing. The RS232 output is independent and it can be configured to give data
after all tags. Card Present (CardPres) is available when the reader is configured for Clock/Data output,
and goes low while data is being transmitted. (The Card Present terminal can also be reconfigured as a
Wiegand Hold input terminal.)
The ELC1 has some protection against connection faults, but they do not cover all circumstances.
3.2 Commissioning
Commissioning the ELC1 is a simple process, consisting of first making sure the reader is working, and
then checking that the data from the reader is reaching the controller.
To check that the reader is working, apply power to the reader. The red LED should come on, as also
should the Data LED. The Noise LED should be off. Bring a tag in towards the reader. Three things
should happen.
The red LED should start to flicker, showing that the tag is being read.
The Noise LED will flicker, and the flickering gets stronger as the tag gets closer to the reader.
The Data LED will flash when the tag is first read. This shows that tag data has been sent. To
get the Data LED to flash again, remove the tag, wait for a few seconds, and then bring it back
in.
Verify that the tag data is reaching the controller and that the green LED (if used) is being driven by the
controller.
The reading range should be at least 90 cm (3ft) if long range is selected (Range connected to Hi) and the
typical range is 1.1m to 1.2m (up to 4ft). With the range reduced (Range connected to Lo) the reading
range should drop to 60 to 70 cm (about 2 ft).
If there are any problems, refer to the Troubleshooting guide in the next section.
