1.2. The CR2A reader A Cryptag Census reader identifies tags (sometimes referred to as tokens or cards) using low frequency radio signals. CR2A transmits to the tag at 153 kHz and detects the tagβs response which is at 115kHz. CR2A uses frequencies which are permitted in USA. The CR2A reader is a cost effective reader for longer range applications that do not require the full capabilities of CR1A readers. The CR2A can only be used with a single antenna loop (internal or external). With the external antenna loop fitted, the reading range depends on the size and shape of the loop as well as on the type of tag. The CR2A reader is configurable, and this is normally done in the factory. Configuration controls the output format, timings etc. Identec Ltd CR2A Reader Installation Sheet TXATXBSCN 0VHold (Card Present)Wiegand D0 (Clock)Wiegand D1 (Data)Green LED 0VScreenV+ (8V to 28V)Serial outSerial in Range Max Low Red Amber Green Noise LED Data LED Te s t Area The printed circuit board of the CR2 reader The CR2 reader can be used as a self-contained reader, using the internal antenna loop, or it can be used with an external antenna loop. Installation The reading range of the CR2 reader is approximately 1.5 metres with the internal loop, and 3 metres with an external loop 2 metres square. With such ranges it is essential to carry out a Site Survey using an MS3A Site Survey Meter to ensure that the site is free from interference. (Since the range is similar to the CR1 reader, you are advised to read the CR1 manual β much of it also applies to this reader.) The reader is mounted using the 3 holes in the base. If the reader is to be used in an exposed position the cable entry hole should be protected. (If a lot of condensation is expected, drill a drainage hole at the bottom of the reader.) All connections to the reader should use screened cables. See below for how to connect the screens. , with the screen connected to the Screen terminal. The screens should be earthed at the controller end. (If this causes problems, connect a 1nF capacitor between the screen and earth at the controller end.) Connections 0V Reference for supplies and data connections Screen All cables must be screened. See below for other details on connections. V+ Positive power supply (8 to 28V at typically 80mA) (Range drops below 13V, falling to 80% at 8V) Serial Out Pseudo-RS232 data output (9600 baud, 8 data, 1 stop bit, no parity) Serial In Only used when configuring readers 0V Extra 0V connection for data cables Hold Normally unconnected.

TXA/TXB Coil connections. Connect to the coil and tuning capacitor If an external loop is used, disconnect the internal coil. The external loop should be tuned with the correct type of capacitor, as close as possible to the loop. The capacitance required can be measured using MS3A Site Survey Meter (or adjust for minimum current consumption into the reader). Screen Connections Screened cables should be used both for the antenna cable and the power/data cable(s). In addition the screen of the power cable must be connected at one end. It is preferred that the screen is connected to the 0V line at the reader and left unconnected at the other end. If the other end of the screen must be connected, then connect a 1nF capacitor between screen connection and 0V. Screened cable, and correct connection of the cable screen, is necessary for good performance. Operation The reading range can be reduced (to 50-60%) by putting the Range link to the bottom. For full range put the link to the top. (Omitting the link is not recommended. It gives an intermediate range, but tags will cease to read very close to the reader.) When a tag is being read the amber LED flashes. The Noise LED flashes if a tag is present, or if there is interference that may affect reading range. The Data LED flashes momentarily when a tag is reported. All tags are reported on both the Wiegand and RS232 outputs. (Unless the tag does not belong to the same site as the reader.) If an external coil is fitted, tags will read within a few centimetres of the Test Area near the coil connections. Identec Ltd February 2002

Configurations and Identification of Device Under Test The DUT is an industrial use RFID system. This system consists of a 154 kHz Tx / 115 kHz Rx module with varying LF loop antenna sizes. (An assortment of antenna sizes have been tested, limited to a maximum loop size of 24 sq. ft. with 3 turns.) A active transponder (FCC ID: JHD-CEN1,2,3,4) is used to communicate with the system. The loop antenna is connected to a series capacitor jumper box for resonating the antenna at the Tx operating frequency (154 kHz). From the capacitor box, 25 ft of twisted pair multi-conductor wire runs to the control box. Within the control box is the AC power supply, LF driver circuitry, and RS-232 interface. Another 25 ft. of RS-232 cable is used to connect the control box to a Laptop computer that receives id numbers from a transponder, as detected by the DUT. The DUT was designed and manufactured by USM Systems, Ltd, Suite 200, 2998 Eleven Mile Road, Berkley, MI 48072. It is identified as: USM Systems, Ltd Transmitter Model: CR2A-USMS FCC ID: RMM-USMS2A-A This test report demonstrates that this device is compliant with the FCC rules and regulations as a LF transmitter for all loop antennas with a minimum effective area of 2 ft 2 (2 ft 2 x 1 turn) and a maximum effective area of 72 ft 2 (24 ft 2 . x 3 turns). 3.1 EMI Relevant Modifications No EMI Relevant Modifications were performed by this test laboratory. 4.
