The V690 Series is the microwave type RFID system which has achieved long-range and high-performance communication. This V690
system is the most suitable for an assembly line, physical distribution, and product control applications.
(1)
Read/Write Antenna Model V690-HMG01
•
Consists of an antenna unit which communicates with the ID tag, and a controller unit which controls the communication.
•
The antenna unit has achieved the transmission speed 600 kbps and maximum communication range 5 m.
•
The antenna uses circularly polarized wave as radio wave. So, the ID tag facing the antenna can communicate at any rotating
angle on the medial axis. The maximum communication range varies depending on the tag angle.
•
This antenna is a specified low-power radio station and, therefore, any radio station license is not required.
•
The Multi Access function which enables to access several tags in the antenna communication area and FIFO (First-In First-Out)
function which enables to access the tags coming in the communication area sequentially one by one.
•
By a command from a host device, the communication 2 m Mode and 5 m Mode can be switched to each other and a radio wave
channel can be switched at a working site. You can select the most suitable communication range at a working site and prevent
the mutual interference between antennas easily.
•
The controller contains both of the RS-232C and RS-422A interfaces. So, it can connect to a general-purpose PC or programma-
ble controller (PLC) which have RS-232C. Also, several antennas can be connected to one host device.
•
A simplified communication test function, which can check the communication with a tag without a host device, and a communi-
cation test, which can check a radio wave environment at a working site, are available.
(2) ID Tag Model V690-D8KR01
•
This tag contains a battery and the memory capacity is 8 kbytes.
•
Write Protect is available to disable writing by 256 bytes.
•
Protective structure based on the IEC Standard IP67 (JEM Standard IP67g) has been achieved. So, this tag can be used even in a
place splashed with water and oil.
•
The battery life is 5 years at 25
°
C (a reference value). The battery is not replaceable, but a power-saving function and battery
voltage alarm function are available.
(3) RS-422A/485 Link Unit Model V690-L01
•
Use when the communication with a host device is made through the RS-422A or RS-485.
•
The power supply to the Read/Write antenna can be turned ON/OFF, the operation/setting mode can be switched, RS-422A/RS-
485 can be switched and terminating resistance can be turned ON/OFF.
