•Humid place where moisture condensation may occur.

•Place affected by vibration or impact.

2.Preliminary check of installation site.

This device uses the frequency band 2450 MHz for the communication between an antenna and tag. Some of radio equipment, such as wireless LAN, cellular phone, personal handyphone system and transceiver, motor and switching power supply may generate a radio wave (noise) which affects the communication with a tag. If you must use this device near such heater, we would like to ask you to check the influence in advance.

To minimize general influence of noise, follow the instructions below:

•Ground any metallic material located around this device according to Class D (Class III).

•Wire this device keeping away from high voltage and heavy 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 water and human body absorb it. Locate an antenna and tag in the communication range and check the radio wave environment in advance.

•The Read/Write antenna model V690-HMG01 has a communication test command to check the radio wave environment 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.

2.Possible trouble due to radio interference

•Communication failure in RFID system

The radio wave from an ID tag to antenna is weak and, therefore, the communication between the antenna and ID tag may fail due to radio interference caused by any other devices. Keep sufficient space between the RFID system and any other devices. For the space, refer to Section 7-6.

•ID tag battery power loss

An electronic circuit in the ID tag is started by a radio wave of other device and the battery power may be consumed considerably. V690 has a tag power-saving function (refer to Section 3-7) to control the battery power. Nevertheless, the battery power may be still consumed depending on a working environment. So, keep sufficient space between the ID tag and any other devices. For the space, refer to Section 7-6.

Correct Usage

•The communication range varies depending on the installation site environment. This is because a metal material and the ground reflect a radio wave, and water and human body absorb it. Locate an antenna and tag in the communication range and check the radio wave environment in advance.

•The Read/Write antenna model V690-HMG01 has a communication test command to check the radio wave environment at a working site. (Refer to Section 3-5.)

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 communication 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 Single mode, only one tag must be placed in the antenna communication 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 tags 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 antenna communication area, such tag can communicate again.

(3) Multi mode

When there are several tags in the antenna communication area, the Multi mode enables to access all those tags. By using the Selective Access function, the communication can be made to a specified tag of those in the antenna communication area.

Correct Usage

When you use the FIFO mode, only one tag must be placed in the antenna communication area. If two or more tags are in the antenna communication area, a communication error occurs. Then, the communication cannot be recovered from 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 available. Those channels can be switched 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 numbers to the channels 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 communication to the tag is made successfully.

(5)When any command has been sent from a host device to the antenna, the communication test stops.
