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. If it does, check the wiring to the LED terminal.
Does the signal to the LED terminal have the correct polarity? (connect to 0V to turn on.)
Tag numbe rs reported incorrectly (Wiegand)
The most likely cause is the Wiegand wires are reversed.
Is the controller set up for the format used by the reader? If the system uses Site Codes, are these set up
correctly?
Tag numbe rs reported incorrectly (RS232)
The reader is supplying data switching from 0 to +5Volts and as such is not true RS232. Tests have
shown that this is compatible with most modern computer terminals.
If the data appears to be garbage, check the baud rate etc. The normal for EC1 readers is 9600 baud, 8
data bits, one stop bit, no parity.
Check that the RS232 line is not too long, and check that connections are properly made. This will often
give occasional errors.
Repair
The reader is designed to be "Installer-Friendly", and is rarely damaged, so please check the
installation thoroughly. In the unlikely event that you find that the reader is faulty, you should
replace the entire reader.
Identec encourages its customers to return faulty equipment, as investigation of faults may help
us improve the product.
12 month "no-quibble" guarantee
All Identec readers and tags are guaranteed for 12 months from the date of despatch from the
factory.
