NORDIC ID HH83/HH85 RFIDACDVAR IANTS

Nordic ID HH83 RFID ACD and Nordic ID HH85 RFID ACD include Advanced Cross Dipole antenna that includes SW controllable (via Nordic ID RFID demo application and NUR API) antenna polarizations (vertical and/or horizontal), enabling a nominal reading distance about 15 m / 50 ft.

NOTE! The reading range depends on used tag and environment

The linear antenna modes (only one antenna is enabled) are intended for long range reading when tag density is high, and tags are in horizontal or vertical position
Enabling both linear antennas provides a lower reading speed but it does provide the best reading performance when tags are in random positions

2D I MAGER

This section describes methods for configuring 2D imager of Nordic ID HH83/HH85. The 2D imager module in use is Opticon MDl-4100 2D scan engine.
There are three different ways to configure the 2D imager that are

1. Using configuration barcode
2. Using Nordic ID RFID demo application
3. Configuring via NURAccessory extension API

USING CONFIGURATION BARCODES

The easiest way to configure 2D imager is to read a configuration code with the 2D imager. Please use Opticon’s online configuration tools to create a configuration barcode and print it onto paper. Then scan the code with the 2D imager of Nordic ID HH83 and new settings will be set and saved automatically.
Quick Instructions to generate imager configuration barcodes:

• Opticon’s online configuration tools: http://opticonfigure.opticon.com/
• Select” Browse’ in the left corner of the page
• Select” Code options’
• Select” Settings of readable codes’
• Select” Enabling of readable codes’
• Select a barcode from the list e.g. Code 39
• Press “Add’ button at the bottom
• From right corner of the page, select” Barcode Type’: e.g. PDF417
• You can adjust the size of the code from the” Barcode Size’
• Select “Advanced’ from the lower part of the right column
• The” 2D code’ field indicates the corresponding configuration string.

Find example configuration barcodes below. More configuration barcodes can be found at APPENDIX 1.

1. Enable 1D codes : Tri-Optic, Industrial 2 of 5, Code 39 and S-Code
2. Disable 1D codes: Tri-Optic, Industrial 2 of 5, Code 39 and S-Code

USING NORDIC ID RFID DEMO APPLICATION

Nordic ID RFID Demo application allows testing of different kind of barcode configurations effortlessly. Configurations can be read and set from specific file. The specific file is a simple text file containing configuration command strings generated by the Opticon’s configuration tool. The configuration settings of Nordic ID RFID demo applications can be accessed via Settings menu or barcode functionality.
Opticon’s configuration tools do provide configuration strings instead of graphic barcodes when you select “Enabling a single readable code” instead of “Enabling of readable codes” in step 4. Barcode type must be 2D-Code like PDF417. Format of configuration string is:

• @MENU_OPTO@ZZ@<config codes separated by @>@ZZ@OTPO_UNEM@

Opticon’s configuration tools shows two or three letter configuration code for each configurable item.

Example:

After sending configuration file to the reader, Nordic ID RFID demo will send “save settings” command automatically to the 2D imager. Source code of Nordic ID RFID demo is public, so one can study how 2D imager configuration using the specific files has been implemented on Android. See section 4.8.2 for more information.

CONFIGURING VIA NUR ACCESSORY EXTENSION API

NUR Accessory Extension API provides command for sending configuration string to the 2D imager:

Return value is byte array of response depending on command code(s) sent to the 2D imager. Null if command string is not valid. The first byte of array contains ACK (0x6 success) or NAK (0x15 fail).

Example:

After sending configuration to the 2D imager, settings are ready to use but next power down causes settings to lost. Therefore, it’s important to save settings to non-volatile memory of imager.

RF PROFILES

The Nordic ID HH83 RFID ACD and Nordic ID HH85 RFID ACD include the Nordic ID NUR2-1W UHF RFID module which supports three different kind of RF profiles. The profiles are Robust, Nominal and High speed. It is important to select the correct RF profile based on use case and environment. More detailed description about the RF profiles can be found below:3

• 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 200 tags/s. Due to the low data speed and best filtering the Robust RF profile provides the best sensitivity.
• Nominal
  • Nominal RF-profile is the default setting of readers containing Nordic ID NUR2-1W UHF RFID module. It uses link frequency of 300 kHz and Miller 2 coding providing read rates up to 350 tags/s.
• Highspeed
  • High speed RF profile is intended to be used in use cases where the highest read rates are required. It uses link frequency of 400 kHz and FM0 coding and provides read rates up to 1000 tags/s. Due to the high data speed this profile is quite sensitive to interferences.

NOTE! Read rates will depend from the environment, reader settings, tag population and tag type.

• Access settings not available in the quick settings dropdown menu.
• Open the applications drawer.
• Update the OS.

The locking is secured using a PIN code, which is decided by the administrator of the device.

CREATE THE DESIRED USER INTERFACE

The first step before locking the user interface is creating the interface which the user will interact with, as any application or setting not included now will not be accessible to the user after locking UI. Please remember that you can have more than one screen and that locking the UI will lock all of them.

1.  Install all the applications which the user should have access to, and create shortcut icons on the home screen for all of them.
2. Edit the Quick Settings Dropdown menu, if the user will be allowed to enable, disable or modify the configuration of each one of those settings, e.g., Wi-Fi, Bluetooth, Battery profile, … You can edit the menu by taping the pencil in the bottom right corner.
3. Select the wallpaper and add any widget which should be visible the home screen. You can configure this by long tapping the home screen background and selection the appropiate option in the pop up menu.
4. If any specific Setting has to be accessible to the user, “Settings shortcut”widgets can also be added, providing a direct access to certain settings such as Battery, Display, Hotspot, Updates, Wi-Fi, Connected devices and many others.

HOW TO LOCK/UNLOCK UI

Once the user interface has been created, it can be locked by long tapping the background and selecting “Lock user interface “in “Home settings”.

Screenshot 10

• You will be prompted to create a PIN code which will be used to unlock the UI in case it is needed.
• The process to unlock the user interface is the same: long tapping the background and unchecking the “Lock user interface” option.
• After the first locking, the device will remember the previous used Pl N code and entering it again is not required, unless you want to change it.
