Section 4
Data Read/Write with ID Tag

4.1 Operating principle

A memory space of 240 bytes is assigned to an ID tag user. With this memory space, an 8-byte area (such as
...
00h-07h, 08h-0Fh
The IDRW head can interact with the ID tag memory as described below.
Data read
In this operation, data is read from the memory in ID tag. The operator can specify up to 16 arbitrary pages
as a read area.
Data write
In this operation, data is written into the memory in ID tag. The operator can specify up to 16 arbitrary
pages as a write area. When intending to write same data to all the pages (same write), there is no limita-
tion about the number of target pages. It is also possible to write a given block of data in steps of bytes (byte
write).

* When the Model V700-HMD13 is used in the system, the data segments assigned to pages 13
through 30 have operational limitations. For further information, refer to "Limitations about Model
V700-HMD13" in the earlier part of this manual. The Model V700-HMD13A does not have such limi-
