KR612D-RS User manual
1 Overview
KR612D-RS 13.56MHZ Contactless IC card reader, is based on ISO / EM4001 international
standard protocol development of non-contact smart card serial number reader. It uses the company's own
design of high-performance RF card reader circuit design; with a high degree of integration,
anti-interference ability, small size, stable performance, cost-effective features. Can provide RS485 and
Wiegand communication interface for access control, time and attendance, fees, security, Patrol and other
radio frequency identification applications。
2. Features
The card reader is equipped with a card-reading antenna that works at 13.56MHz.
The effective distance ranges from 0 to 5cm, depending on the working environment and card type.
The data receiving time is less than 80ms within the effective distance.
The card reader adopts the single +12 VDC power supply, and the operating current is less than
100mA.
The data is output in the standard Wiegand34 bits format by default. The format can be converted
between Wiegand34 and Wiegand66.
The card reader is produced using the fully closed rubber injecting operation to achieve the
waterproof and moisture-proof effects.
The effective distance is associated with the voltage of the power supply, used IC cards, and operating
environment.

6 Precautions
1. The operating frequency of the card reader is 13.56MHz. Therefore, interference frequency ranging
from 13MHz to 15MHz cannot exist on the site where the card reader is installed.
2. To prevent emission magnetic fields of card readers from affecting each other, the installation distance
between every two card readers must be greater than 10 cm.
Attachment 1
"Hereby, ZKTECO CO., LTD. declares that this Card Reader is in compliance with the essential
requirements and other relevant provisions of Directive 2014/53/EU.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received,
including interference that may cause undesired operation.
Warning: Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
