1. CRYPTAG CENSUS LABEL READER
1.1 Introduction
Cryptag Census is a high performance tag identification system, offering fast long range multiple reading
with the CR1 readers. Complementing the top end CR1 readers and short range EC1 range of readers, the
ELC1 (ELC1A-USA) reader provides a mid-range solution where moderate reading range is required.
The ELC1 is easy to install, and its thin profile means it can be mounted unobtrusively, for instance on
doors.
All Census Tags work on all Census Readers.
For most applications the instruction sheet provided with each reader should suffice. Installers should
rarely (if ever) need to refer to this manual, which should be treated as a reference document. This
manual complements the Cryptag Census Site Manual, which for instance contains data on the Census
tags.
1.2. The ELC1 reader
A Cryptag Census reader identifies tags (sometimes referred to as tokens or cards) using low frequency
radio signals. ELC1 transmits to the tag at 131kHz (in USA 153 kHz) and detects the tag’s response
which is at 98kHz (in USA 115kHz). The USA version is denoted as ELC1A.
The ELC1 reader is configurable, and this is normally done in the factory. Configuration controls the
output format, timings etc.

1.4 Getting started
1. Connect a power supply to the reader.
The positive connection goes to V+ (terminal 1), while the negative connection goes to 0V (terminal 2).
The supply should be at least 5V, and should not exceed 18V. For optimum range the supply should be at
least 12V. For supply voltages less than 12V reading range will be reduced.
2. Bring a tag near the reader .
The reading range should be at least 100cm (39 inches) for a TC1 tag, but is usually more. (Reading
range is reduced unless terminals 3 and 4 are connected.)
3. The red LED 2 (see page 9) will flash when the tag is within range.
The red LED 2 will flash when the tag is being read. At the same time the red “Noise” LED 4 will
flicker, and the flickering gets more intense as the tag gets closer to the reader. The green “Data” LED 3,
and will blink once when the tag’s identity is reported.
4. The reader reports the tag only once.
The reader sends the identity of the tag when the tag is first identified. (As shown by the Data LED 3
blinking). To get another report, take the tag away from the reader for a few seconds, then bring it back
in towards the reader.
