Appendix A TECHNICAL DATA
For more information on Cryptag Census in general, refer to the CR1 Site Manual.
The reading range of ELC1 is specified at 90cm minimum with a TC1 tag, but in general better ranges
will be achieved. (Typical ranges are 1.1 metres to 1.2 metres.) This range assumes that the tag is in the
optimum orientation.
Reader mechanical details
Dimensions 213mm x 163mm x 4.7mm
8.4 x 6.4 x 0.2 inches
Weight approx 200g (7 ounces)
Colour/Material Grey ABS case.
LEDs
Red (internal control)
Green (external control)
Noise indication (red)
Data sent (green).
Electrical connections
Screened cables are required to meet EMC requirements, as approvals were obtained with
screened cables.
Power input.
5-18V d.c. 60mA typical. (current depends on LED status.)
100mA max.
The ELC1 power connection is reverse voltage protected. There is a slight danger that incorrect
connections on other terminals can damage the reader.
Wiegand output
Data on D0 and D1.
Low going pulses 100µs long. (All timings are potentially configurable.)
1.6ms pulse separation
Minimum 250ms between transmissions.
Internal 1k pull-ups.
Clock/Data output
This uses the same circuitry as the Wiegand output.
RS232 (NOT TRUE RS232)
Operates 0Volts Pulsing to +5Volts
Transmit data only. No receive function.
9600 baud, 8 data bits, no parity, one stop bit.
The reader reports a power up message, identifying itself.
Each tag is reported in ASCII code, e.g.
HID=0014 PID=1234
The numbers are reported in hexadecimal.
Configuration
ELC1 readers are normally configured by Identec. For advice on equipment to configure ELC1
readers, contact Identec.
