Appendix 1 Glossary
Antenna
In this manual, this refers to the Read/Write antenna, a reader/writer which accesses an ID tag of the RFID system.
ARIB
Association of Radio Industries and Businesses, which issues the standards for radio equipment based on the Radio Law of Japan.
The first edition of Specified Low-Power Radio Station - Radio Equipment for Mobile Object Identification RCR STD-29 was
issued in 1992 and revised in July 2000 into Version 3.0
ASCII
American Standard Code for the Information Interchange. American standard character code. This is almost the same as JIS 7 unit
code for alphanumerical character, except that "¥" in JIS code is "\" in ASCII code.
AWG
Shows a wire size. As the AWG number becomes small, the wire size becomes large. For the cable of this product, cross-sectional
area of AWG22 is approximately 0.45 mm
Circularly polarized wave
A wave that direction of electrical field (or magnetic field) is one way and not affected by time and place is referred to as "Linearly
polarized wave". On the other hand, a wave that direction of electrical field varies depending on time and place, i.e., the electrical
field rotates in the radio wave transmitting direction, is referred to as "Elliptically polarized wave". Among the elliptically polarized
waves, a wave that amplitude is constant is the circularly polarized wave.
Command
In this manual, this refers to an instruction from a host device to the Read/Write antenna.
Communication
In this manual, this refers to data communication between a host device and Read/Write antenna. Data communication between an
ID tag and Read/Write antenna is referred to as data exchange.
Data exchange
In this manual, this refers to data communication between an ID tag and Read/Write antenna.
Grounding Class D
Grounding method that grounding resistance is 100 Ω or less. This was formerly referred to "Grounding Class III".
Half-duplex communication
Although this is two-way data transmission, transmission can be performed only in one way at a time. In the full-duplex communi-
cation, the data transmission can be done in two ways simultaneously.
HEX
Hexadecimal number. A method to express a numerical value. The hexadecimal numbering system has a base of 16. The numbers
0 to 9 and characters A to F are used. The characters A to F correspond to the decimal numbers 10 to 15.
Host device
A device, such as PC, programmable controller (PLC), etc., to issue a command to the Read/Write antenna.
JIS8
Character code of JIS. There are 8 unit code (8 bits) and 7 unit code (7 bits). JIS8 unit code is for both of alphanumerical character
and Japanese Kana character.
2
m/s
Unit of acceleration based on SI (International System of Units). The old unit is "G". 1G = 9.807 m/s
Microwave
This product uses 2450 MHz which is recognized as IMS band (for industrial, medical and scientific purpose) in the world.
N•m
Unit of torque based on SI (International System of Units). N is Newton. The old unit is "kgf•m". 1 kgf•m = 9.807 N•m.

and that of AWG26 is approximately 0.18 mm
