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. The RF section was optimized by using a circulator. Thus, the combination of the R2000 chip and circulator based RF section with auto sensitivity improving technology provides the very best performance possible. Therefore, OR8400 is superior to all other R2000 base designs. 2 Hardware Block Diagram OR8400 can be controlled via USB interface. OR8400 can connect 4 antennas via R/P TNC connectors.

[2] The OR8400 module may be considered as a single electronic component. It is designed so that all the internal components have safe margins to their thermal limits when the heat spreading plate (bottom) does not exceed 70C. The heat spreading plate temperature must not exceed 70 degrees C. Heat sinking will be required for high duty cycle applications. 4 Federal Communication Commission Interference Statement interference received, ThisdevicecomplieswithPart15oftheFCCRules.Operationissubjecttothe followingtwoconditions:(1)Thisdevicemaynotcauseharmfulinterference, and (2) this device must accept any including interferencethatmaycauseundesiredoperation.

ThisequipmentcomplieswithFCCradiationexposurelimitssetforthforan uncontrolledenvironment.Thisequipmentshouldbeinstalledandoperated withminimumdistance20cmbetweentheradiator&yourbody. 5 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. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: Contains FCC ID: NKR-OR8400. The grantee's FCC ID can be used only when all FCC compliance requirements are met. Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. 6 4 Hardware interfaces 4.1 AntennaConnections 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 AntennaRequirements 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. 4.1.2 AntennaDetection To minimize the chance of damage due to antenna disconnection, the OR8400 supports antenna detection. Detection can be done automatically and manually. Antenna detection helps protect the module from possible damage due to return losses less than 6 dB. 4.2 Digital/PowerConnectorDefinition The digital connector provides power, serial communications signals, LED signal and reset signals to the OR8400 module. These signals are provided through a connector that is compatible with part number: Molex 53261-1571 -
1.25mm pin centers, 1 amp per pin rating which mates with Molex housing p/n 51021-1500 with crimps p/n 63811-0300. DigitalConnectorSignalDefinition PinNumber 1 2 3 PinDefine GND GND

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). Each time a CRC error in the EPC is detected, LED_CRCError turns on. If no error is detected, LED_CRCError turns off. 9 5 Mechanical Dimension 10
