Data area EPC TID User dataBytes 62 16 8K

The table above is only for reference. Tag volume may increase through software upgrade.

● EPC introduction:Data reading speed is higher for EPC; recommended for regular data

● TID introduction:TID (Tag identifier) is a unique identity mark between tags. Each tag’s TID is unique from the viewpoint of safety and security. A tag’s TID will never appear or activated on another tag, once the TID is under “Killed” status. Therefore, even if the other area of data is replicated, it can still be identified through its unique TID.The composition of tag TID is as follows: Class identification code (8 bit) + Manufacturer code (12 bits) + Tag model (12 bits) + Tag serial number (Difference tag manufactures have different capacities)

● User data introduction:

● Data reading speed is lower for user data; recommended for uncommon data.

9. Routine maintenance, FAQs and troubleshooting

9.1 Routine maintenance

Store the device in a cool and dry place, with temperature ranged between +10oC - +40oC. Avoid contact with corrosive substances and keep away from fire and heat sources (For details please refer to 8.2 storage requirement).

Due to the self-discharging characteristics of lithium battery, if the device is not being in use for a long period of time (not less than 1 month), it is recommended that the battery should be removed from the handheld device and stored separately (Battery capacity is best for long term storage at 40%, and should be fully charged and left discharged every three months, if possible).

Precautions for battery usage:

● Do not directly connect the input to output terminal;

● Do not expose the battery to water or get it wet;

● Do not use or store the battery near a heat source (such as fire or heater);

● Please use original charger;

● Do not reverse the positive and negative;

● Do not plug the battery directly in a wall outlet or car cigarette lighter socket;

● Do not put the battery into a fire or heat up the battery;

● Do not use wire or other metal to connect the positive and negative terminals of the battery, do not transport or store the battery with necklace, hairpins or other metallic objects;

● Do not disassemble the battery or cause battery short circuit;

● Do not cause impact to the battery or use sharp object to hit the battery.

This section introduces solutions to some of the common problems or irregularities during the usage of the device.

● How to perform “restart”?

○ Click on the Start menu at the bottom left corner of the main screen, then click on “System Power”→ “Restart”

○ Press the keyboard softkey using stylus, release once the screen turns black. Press the power button to restart, and then proceed with normal startup process.

● No audio

○ Check if system audio has been adjusted to the minimum

● Black screen and no response after clicking

○ Check if the device is in standby mode, click on “On/Off” button to launch the system

● Please check if the battery is loosened

● Unable to read tag

○ Please confirm if the electronic tag is within the effective range of reader;

○ Please confirm if there is any RF signal interference.

● Unable to write tag

○ Please confirm if the electronic tag is within the effective range of the reader;

○ Please confirm if the data area of the electronic tag has been locked;

○ Please confirm if the instruction parameter is configured correctly;

○ Please confirm if there is any RF signal interference.

● Why is the tag writing distance closer than data reading distance?

○ This is due to the special characteristics of RFID technology. Tag writing requires more energy than tag reading, hence the distance is shorter and suc-cess rate of tag writing is much lower as compared to tag reading.

● Why do the reading distances for various tags appear to be so different?

○ This is due to the special characteristics of RFID technology. Different tag chip and their sealing materials have different sensitivity towards the reader;



33

hence the operating distance and success rate are different.

● GRPS is unusable after launching/restarting the system

○ In order to use GPRS module, both power supply and corresponding driver programme are required. Please follow “Introduction on GPRS module application” to connect to the GPRS network. If you wish to use the GPRS module constantly, it is recommended to follow the methods demonstrated in “Power scheme setting”, and change the “Standby” mode to “Never” mode.

● Crashes or white screen occurs during file transfer when the handheld device is under synchronization with PC

○ Unplug the battery and reboot the handheld

○ If the problem persists, you shall proceed as follows:

○ Go to “Control Panel” → “Storage Manager” → select storage device (Flash or TF memory card) and select “Remove” → Once “Format” is successful → enter new name under “New”

After formatting, the data in micro TF card will be lost.

● When Flash or TF card crashes

○ Conduct the following procedures on the reader:

○ Go to “Control Panel” → “Storage Manager” → select storage device (Flash or TF memory card) and select “remove” → Once “Format” is successful → Restart

After formatting, the data in micro TF card will be lost.

● Handheld device unable to start properly (Black screen or crash) after plugging in power adapter or battery

○ Black screen

▫ Check if PC is connected with handheld device through USB data cable. If connected, please unplug the USB cable, and plug in power adapter. Restart the device after that.

▫ Check if the power adaptor is plugged in tightly or the battery is installed properly.

○ System Crash

▫ If there is a progress bar, restart the reader

▫ If there is no progress bar, please contact our sales representative

9.3 RF Communication optimization

Under normal circumstances, radio technology is used for device communication. The system performance is very sensitive towards signal interference and attenuation. This section provides some tips for radio communication optimization between XC2903 and electronic tags.

9.3.1 Signal Interference

Signal interference refers to the radio frequency (RF) signal that caused interference to the data exchange between the handheld reader and electronic tag. Signal interference can severely affect the capability of a handheld reader to retrieve information from an electronic tag.

Sources of signal interference

● Radio frequency (RF) system, such as RF local area network and nearby interactive identification system;

● RF signals from security doors, garage doors or other devices

● Other RF radiation sources

When there is radio frequency (RF) interference or noise, the performance of handheld reader (with regard to its data exchange with electronic tag) will be reduced significantly. Handheld reader can only “accept” one signal at any given time, and it is not capable to distinguish between undesirable noise and useful RF signals.

9.3.2 Signal attenuation/reflection

Signal attenuation refers to the natural attenuation of signal strength, resulted from the distance. It may be due to the obstacle encountered in its transmission path.

Possible obstacles for radio frequency signal:

● Enclosed space with concrete walls, floors and ceilings

● Metallic surface surrounding antenna or tag

● Water or other liquid surrounding antenna or tag

Almost every object (including furniture or partition) will cause a different degree of attenuation during transmission process. This attenuation resulted from obstacle can be reduced to the lowest degree through careful repositioning of antenna installation position.



35

At the same time, the reflection caused by metal or metalized surface on the back of the electronic tag may also contribute to signal attenuation. Under some circumstances, this causes slight increase in reading distance and results in blind corners. At these blind corners, the communication between the electronic tag and handheld reader is very poor.

Generally, it is impossible to conduct accurate prediction of the handheld reader system’s performance under any given environment (this is due to the complexity of electromagnetic radiation, including stability of frequency of signal source, antenna pattern, antenna sidelobe, and the surrounding environment). However, some of the recommendations given below can provide a certain degree of guidance in the specific environment, as well as application in optimizing system performance:

● Take into account the radio frequency (RF) characteristic in the surrounding area, including building materials, office hour, windows, and piping configuration. Radio frequency (RF) field mode and reading distance may be affected by metal objects nearby, such as household appliances, equipment and metal frames.

● The electronic tag must remain in the effective reading area of the handheld reader for not less than 100ms (for XC-TF8030-B-C07 electronic tags).

● The optimal antenna length for electronic tag is related to the non-conductive materials sealed or embedded with the tag. Here is the basic concept: For electronic tag embedded within non-conductive materials (The dielectric constant is generally larger than the dielectric constant in the air, causing the effective wavelength of the medium to be shorter than the wavelength of the air) or placed in substrate, if its effective wavelength has been adjusted to the optimal length in open space (at the furthest reading distance from the handheld reader), the electric length of the tag antenna must be reduced to achieve the best effect in open space. On the contrary, if the effective wavelength has been adjusted to the optimal length within non-conductive materials, the electrical length of the tag antenna must be increased to achieve the best effect in open space.

● Do not expose naked, unsealed electronic tag with chemicals. Certain chemicals, such as alcohol, can be corrosive under high temperature, even though they are safe under normal temperature.
