    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.
  • Page 30: Simplified Communication Test

    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.

  • Page 34: Id Tag Power-Saving Function

    3-7 ID Tag Power-Saving Function The tag has the two power-saving functions below. ♦ ♦ ♦ ♦ Function to prevent battery power loss due to radio wave emitted from any other radio equipment (Enabled always) If any radio equipment is located near a tag, the tag operates (ready to operate) because the tag’s receiving band is wide. As a result, the tag battery may be consumed.
  • Page 35 3-7 ID Tag Power-Saving Function ♦ ♦ ♦ ♦ Function to prevent battery power loss due to neglect when tag works (Enabled always) When you use the antenna with a repeat command (refer to (3) in Section 5-2-1), due to a trouble in a working site, the tag may be left in front of the antenna which is emitting a radio wave, although the tag operates (ready to operate).
  • Page 36: Chapter 4 Installation And Connection

    The maximum communication range varies depending on the rotating angle of the tag. Refer to Section 7-3. • Conceptual diagram of circularly polarized wave Antenna * A hatched area on the tag shows the logo "omron".
  • Page 37 4-1 Read/Write Antenna and ID Tag (4) Influence of external objects • Radio wave absorbers: water, human body, water screen, water-absorptive material, etc. A radio wave (microwave) penetrates anything (solid body and liquid) other than metal, but it is attenuated while penetrating. In partic- ular, water absorbs a radio wave extremely.
  • Page 38 4-1 Read/Write Antenna and ID Tag • Communication area affected by the ground If an antenna is installed near the ground, radio waves (microwave) emitted from the antenna and ones reflected by the ground overlap each other. Therefore, an outline of the communication area becomes ragged and complex. In this case, dead zones may be formed fre- quently, where no communication can be made to the tag.
