1 Introduction OR8400 is a superior, high sensitivity and high performance 4 ports RFID reader module with built-in Impinj Indy R2000 RFID reader chip. OR8400 supports EPC class1 Gen2/ ISO 18000-C. The maximum RF output power is 30.0dBm. The typical sensitivity is -84dBm at 30dBm output power. OR8400 supports auto sensitivity improving technology. It can improve more than 10dB sensitivity. In summary, the R2000 RFID chip was chosen because it provided the very best basic performance.

Federal Communication Commission Interference Statement 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. 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.

This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter test will not be required.

4 Hardware interfaces 4.1 Antenna Connections OR8400 supports four mono-static bidirectional RF antennas through four reverse polarity TNC connectors. The maximum RF power can be delivered to a 50 ohm load from each port is +30.0 dBm. 4.1.1 Antenna Requirements The sensitivity of most of RFID reader is affected by antenna return loss. OR8400 supports auto sensitivity improving technology. The technology can reduce the effect to keep good sensitivity. The minimum antenna return loss is 10dB. 4.1.

Antenna status table 4.2.2 Antenna ANT1 ANT0 Antenna1 0 0 Antenna2 0 1 Antenna3 1 0 Antenna4 1 1 LED signal During an inventory command execution, two LEDs (LED_CRCError and LED_Link) are used to indicate the tag read status. LED_Link is turned on each time a valid EPC is received. LED_Link turns off when a tag is not read (for any reason).
