2021-12-16 NUR3-1W6 Hardware implementation guide Version 1.0 4.2. HEAT TRANSFER CONSIDERATIONS For NUR3-1W module to operate normally in different ambient temperatures, a proper hear dissipation design needs to be followed. Recommendation is that heat transfer block is used to maximize the heat transfer from the module into the chasses of the end device. In below picture you can see the reference implementation. Picture 4. Reference heat mitigation implementation of the NUR3-1W6 module. 4.3.
2021-12-16 NUR3-1W6 Hardware implementation guide Version 1.0 4.5. I2C IO EXPANDER AND LEDS NUR3-1W6 provides visual LED indicators which Host can control thru I2C interface exposed thru bottom pad contacts. LEDs are driven by on-board I2C IO expander IC. 5. RF AND INVENTORY SETTINGS Using a proper set of RF and inventory settings is mandatory for reaching the optimal reading performance. 5.1.
2021-12-16 NUR3-1W6 Hardware implementation guide Version 1.0 Robust Robust RF profile is intended to be used in challenging environments. It provides the best filtering against the interfering signals coming from nearby reader(s), other signal sources and from reflective environment. This profile uses link frequency of 250 kHz and Miller 4 coding scheme providing read rates up to 250 tags/s. Due to the low data speed and best filtering the Robust RF profile provides the best sensitivity.
2021-12-16 NUR3-1W6 Hardware implementation guide Version 1.0 5.1.6. DYNAMIC POWER SAVE MODE NUR3-1W6 module has dynamic power save modes which can be enabled via NurApi. By default, the power save is off. There are three depths for the dynamic power save mode to select from: 100ms, 500ms and 1000ms. The power save mode works in a way that when module reads continuously (applies only when using inventory stream -command) it goes to sleep if there are no tags in the field.
2021-12-16 NUR3-1W6 Hardware implementation guide Version 1.0 5.2.1. Q-VALUE The Q-value defines the amount of open response slots that tags can use per one inventory round. Number of slots can be calculated by formula 2Q. It is advised to use twice as many slots compared to number of tags that you have in your readers reading field simultaneously. Selectable values are 0 – 15 where 0 means automatic Q-value adjustment.

ROUNDS The rounds setting defines how many query rounds is done inside one inventory round. After every inventory round the reader will send data to the Host. Selectable values are 0 – 10. In the legacy readers the Rounds setting 0 is automatic adjustment which is not supported with NUR3-1W6 module. With NUR3-1W6 UHF RFID module Rounds 0 corresponds to Rounds setting 2.
2021-12-16 NUR3-1W6 Hardware implementation guide Version 1.0 6.1. TAG REPLAY QUALITY INDICATORS Tag replay quality indicator values are reported to the host system together with read data of the tag. Note, that to also obtain the tag phase rotation value or phase difference value, you need to enable this functionality first via NurApi. Please refer to Nur API documentation for more detailed information. 6.1.1.

2021-12-16 NUR3-1W6 Hardware implementation guide Version 1.0 ANTENNA REQUIREMENTS Maximum allowed ERP power is 33dBm when operating in ETSI lower band. NUR3-1W6 has maximum output power of 30dBm. Meaning that 5dBi is the maximum allowed antenna gain without cable losses (ETSI lower band). When module is set to operate in ETSI upper band, maximum ERP power is 36dBm. This means maximum antenna gain of 6dBi. Formula how to calculate maximum allowed antenna gain when operating in ETSI lower band: 30 dBm – 2.
