Page 6: Introduction
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. -
Page 7: Chapter 2 Reader Location
If there are readers from other manufacturers there may be an interaction. If the other reader uses frequencies similar to those used by Cryptag Census the safe distance may be more than expected. (This is because Cryptags are more sensitive than most tags.) ELC1 readers should not be mounted directly on to a metal surface. -
Page 8: Installation
Page 7 of 21 INSTALLATION AND COMMISSIONING Installation Cabling Use screened cable, with the cable screen earthed at the other end from the reader (the controller end). Preferably the cable should not be more then 100 metres (330 ft) long for Wiegand interface, or 10 metres (33 ft) for the RS232 interface. - Page 9 Page 8 of 21 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.

Page 9 of 21 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. -
Page 11: Chapter 4 Troubleshooting
Data LED does not flash when a tag is brought in. This suggests that the tag is not being read. Make sure that the tag you are using is a working Cryptag Census tag. Is there another reader in the vicinity? See the section on reduced range. - Page 12 Page 11 of 21 Are there any other electrical systems that could cause interference. Try turning electrical equipment off to see if the reader is affected. Green LED does not come on Disconnect any wires to the LED terminal, and connect a wire from the 0V terminal to the LED terminal. The green LED should come on.

Page 12 of 21 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. -
Page 14: Appendix B Approvals
If you make an unauthorised modification, you may invalidate that approval, and you might be committing an criminal offence (depending on local legislation). Low Voltage Directive Cryptag Census readers have been designed and manufactured in accordance with EN60950, following the provisions of the Low Voltage Directive. ISO 9002... -
Page 15: Appendix C User Instruction
Do not leave the tag in a hot place (e.g. on a radiator). This tag contains a small battery, which under normal circumstances will last 5 years. Battery life will be reduced if the tag is left for long periods within range of a Cryptag Census reader. -
