Installation precautions: The from the card reader to the controller: It is recommended to use an 8-core shielded multi-strand twisted pair network cable (two of which are spare, if the card reader light feedback legal card is not required, the LED cable can not be connected, if the buzzer of the card reader is not used) The Buzzer can not be connected to the illegal card feedback from the device), and the data lines Data1 and Data0 are a pair of twisted pairs.

The wire diameter is recommended to be more than 0.3 square millimeters. The longest can not exceed 100 meters. The shield wire is connected to the GND of the controller.
The card reader is installed a metal surface. Since the card reader is a radio frequency product, the metal pair near the front or the rear will absorb its radio frequency signal. If the metal surface is large, it will even affect the card reader. card, or the reading distance is very attenuated.
The distance between the two card readers will also affect the card reader, some will shorten the card reading distance, and some will cause the two card readers to read the card at the same or the card reader cannot read the card.
Solution: Try not to insta
