EXPANSION READ (XR)
The EXPANSION READ command reads up to 2 KB of data from a Tag by dividing the response into
frames. If there is no Tag in the communications area, the ID Controller will return an error response
with an error code of 72 (Tag missing error).
The host device cannot send another command to the ID Controller until all response frames have
been received. (Excluding the AA command and XZ command.)
1:1 Protocol
Responses with 256 or Fewer Characters
Data designation Specifies the code format when sending the read data response.
“A”: ASCII
“H”: Hexadecimal
Antenna designation Specifies the Antenna with which to communicate.
“1”: Antenna 1
“2”: Antenna 2
Read area start address Specifies the start address of the area in the Tag from which data is to be read from in 4-digit
hexadecimal.
Setting range: 0000
H to FFFFH
No. of bytes to read Specifies the number of bytes to read from the Tag in 4-digit hexadecimal.
Up to 2,048 bytes can be read with one command.
Setting range: 0001
H to 0800H
• 1000 Byte Tags (V680-D1KP@@)
ASCII: 1000 bytes (1000 characters)
Hexadecimal: 1000 bytes (2000 characters)
• 8-/32-KB Tags (V680-D8KF68/-D32KF68)
ASCII: 2048 bytes (2048 characters)
Hexadecimal: 2048 bytes (4096 characters)
• 2000 Byte Tags (V680-D2KF@@)
ASCII: 2000 bytes (2000 characters)
Hexadecimal: 2000 bytes (4000 characters)
End code Indicates the execution result for the command.
“00” indicates a normal end.
Refer to List of End Codes for information on other end codes.
p. 235
Read data The data read from the Tag.
The number of characters will be the same as the specified number of bytes to read for ASCII
data and twice that number for hexadecimal data.
