2. Preliminary check of installation site.
This device uses the frequency band 2450 MHz for the communi cation between an antenna and ta g. Some of radio equipment, su ch
as wireless LAN, cellular phon e, personal handyph one system and transceiv er, motor and switching power supply ma y generate a
radio wave (noise) which affects th e commun icat ion wi th a t ag. I f you must use this d evic e near s uch he ater, we would li ke to ask
you to check the influence in advance.
To minimize general influence of noise, follow the instr uctions below:
• Ground any metallic material located around this device according to Class D (Class III).
• Wire this device keeping away f rom high voltage and h eavy current.
3. Ambient environment and communication range
• The communication range varies depending on the installation site environment. This is because a metal material and the ground
reflect a radio wave, and wa ter and human bod y a bsorb it . Loc ate an anten na and ta g in th e commu ni cation range an d ch eck t he
radio wave environment in advance.
• The Read/Write antenna model V690-HMG01 has a co mmunication test command to check the radio wave en vironment at a
working site. (Refer to Section 3-5.)
4. Be sure to ground any ground terminal according to Class D (conventional Class III). Otherwise, performance may deteriorate.

Chapter 3 Functions
3-1 Single/FIFO/Multi Mode Access Function
You can use one of the three communication modes according to the number of tags in the communi cation area and the situation. The
communication mode can be specified in the communication designation in a command.
(1) Single mode
In the Single mode, the communication is made to one tag in the antenna communication area. In the Sin gle m od e, o nly o ne ta g m u st be p laced in the a n tenn a co mmunication area. If two or more tags are in the antenna communication area, a
communication error occurs.
(2) FIFO mode (First-In First-Out)
The FIFO mode enables to access the t ags coming in the communication area
sequentially one by one. When the communication to one tag has been completed,
the tag is prohibited from communicating. So, even if there is any tag, which
ended the communication, in the antenna communication area, the communication
can be made to the next target tag. When the tag prohibited from communicating
has gone out of the antenn a communication area, such ta g can communicate again.
(3) Multi mode
When there are several tags in th e antenna communication area, the Multi mode
enables to access all those tag s. By using the Selective Access function, the communication can be made to a specified tag of those in the anten na communication
area.
Correct Usage
When you use the FIFO mode, only one tag mus t be plac ed in the a ntenna commu nicat ion area . If two or mo re tags are
in the antenna communi cation area, a c ommu nicati on error oc curs. Then , the comm unica tion ca nnot be recove red f rom
failure unless only one tag is in the antenna communication area.
3-1
3-2 Communication 2 m Mode/5 m Mode Switching
The communication 2 m mode and 5 m mode can be switched to each other by a command from a host device. Use either one depending on a working site.
For the command, refer to Sections 5-9-2 and 5-9-3. The default value is the 2 m mode.
For the communication area of 2 m mode and 5 m mode, refer to Section 7-1.
3-2
3-3 Radio Wave Channel Switching
In this RFID system, a range from 2437.5 to 2462.5 MHz in the 2450 MHz frequency band can be divided into ten, and 10 channels (at
2.5-MHz intervals) are availa ble. Those channels can be sw itched by a command from a host device. Use them to prevent the mutual
interference between antennas or interference caused by any other devices.
For the command, refer to Sections 5-9-2 and 5-9-3. The default value is Channel 5 (2450 MHz).
Channel
2450 MHz frequency band
Correct Usage
Due to dispersion of frequency, the frequencies of adjacent channels may overlap each other. Do not assign consecutive numbe rs to the chann els of adjacent antennas.
3-3
3-4 Simplified Communication Test
You can check the communication between an antenna and tag using the antenna only without connecting to a host device.
In the simplified communication test, the antenna detects the tag at approximately every 2 seconds and, if the tag responds, it turns on
the indicator C.
(1) Turn off the power supply.
(2) Short-circuit the setting terminals "+P" and "-P".
(3) Turn on the power supply. Then, the setting mode is enabled. (Refer to Section 5-1.)
(4) The simplified communication test starts. As shown below, the indicator C (Radio wave emission) shows whether the communica-
tion to the tag is made successfully.
(5) When any command has been sent from a host device to the antenna, the com munication test stops.
