4－Decode /error, two-colour light(green or red),green lighting indicates that the
interrogator read the tag data correctly. Red lighting indicates that the interrogator
read tag data error;
5－communicate/connect, two-colour light(green or red),green lighting indicates
that the interrogator is transmitting data to PC via Network Interface. Red lighting
indicates that the interrogator established a network connection to PC successfullly;

modulated carrier signals and transmit the signals by selected antenna.
→The unit receive the back scatter signal from the RFID tag.After demodulating ,
amplifying ,comparing the signals ,the unit transmit the signals up to baseband unit.
→The unit adjust output power and frequency of the antenna interface under the
control of the baseband unit.

3.1.2 Baseband unit:
→The unit receive data & command from PC via RS-232 interface,or send data &
results to PC ;
→The unit transmit control signals of tags to RF unit;
→The unit accept tag signals from RF unit, modulate signals and checkout;
→The unit can modify or query configure information of interrogator under the
control of PC command ;

3.1.3 Power unit:
→converts incoming alternating current (AC) to direct current (DC),out DC power
supply for the integrated equipment.

3.1.4 Data interface unit:
→Standard connector to connect the COM port ,network and power interface with
the rear panel of the integrated equipment ;

3.1.5 Case unit:
→The interrorgator case is made of molded-in ABS/PC. And the anti-static coating
was sprayed over the inner surface of the case;

3.2 Fundamental working principle
The complete RFID system is consist of XCRF-804 interrogator, antenna, tags,
and pc.
The baseband send the command to RF unit under the control of PC.RF unit
send signals to tags according to the tag type. When the tag is activated, it sends out
its number as well as other information .
The tags' response signals was amplified and shaped by the received-data

circuit. Then the signals was send to baseband unit. The baseband will decode the
received signal and then sends to PC via the communication interface of the
baseband unit.
The transmitting part of the RF unit will take the function of carrier generation,
carrier modulation, amplification and emission. The receiving part of the RF unit
will take the function of demodulation, amplify , compare etc.
The FPGA part of baseband will take the code/decode function to tag data.
MCU will take the function of communication with PC.

4 Usage and operation

4.1 Interrogator connection
There are 4 antenna port on the XCRF-804 interrorgator .The output port of
antenna interface is SMA plug.
You can find antenna Cable with reversed SMA-Plug to N-Plug Connector in
the product accessories. Joint the antenna SMA plug to the SMA interface of
interrorgator and tight the bolt. The fit another port of the antenna cable with proper
antenna.

4.2 Interrogator usage and operation
Connect the device as stated above, and the interrorgator will work under the
control of PC command. Our company provide API function and interrogator
demo software .User can use the software to test the interrogator. Please read user
manual of the interrogator demo software to get the information about test procedure
and test method.

5 Usual failure analysis and exclusion
·When the interrorgator is power on the signal lamp is not lighted:
→power fault: check if the input alternating current power is normal. The
alternating current voltage should between 85V～265V;
→If the other signal lamp is light, there is MCU or FPGA fault in the device. Once
you meet this problem, you can only contact with Invengon company to repair the

device;
·Can't read tag data:
→Please check if the serial port or the network cable is connect to the interrogator
correctly. If the cable is not joint firmly, interrogator can not get command from
PC.
→If the power amplifier signal lamp is light ,user need to check if the antenna SMA
connector is screw down, or if the tag is fault. But if the power amplifier is not
light, maybe the FPGA or MCU is fault. User should contact Invengo company
to repair the device;

6 Other notice

6.1 Production warranty
The warranty: period of our products is 2 years from delivery . If a defective is
found due to material processibility qualified problems of the product , we will
perform warranty commitment. Invengo company will decide whether repaire or
replace the fault product with certain qualified problem.

If a problem occurred is because the user's operation environment is not accord with
the product Specifications, or a problem occurred due to installation reasons, we will
not perform warranty commitment. we may charge the maintenance costs.

6.2 Safety note
When interrorgator is working (emitting microwave),person who install or
operate the device should be 30cm away from antenna to meet the FCC safety
standards requirement about maximal tolerant radiation human body can take.
The item should be carry out when user intall or operate the interrorgator.
Not undertake item:
Any RF device, include this interrogator , maybe disturb the medical device
without correct protection. If you face this problem , you should listen to the counsel
of medical device manufactory . This interrorgator may disturb other device when

working .
