Communications
AUTO READ (AR)
For AUTO READ, the ID Controller waits for a Data Carrier to approach and then reads data from Data
Carrier memory. The ID Controller will return a response to the host device when communications with
the Data Carrier have been completed.
■
1:1 Communications
Data code specification
Specifies the type of code in which to send the read data in the response.
A: ASCII
H: Hexadecimal
R/W Head No.
Specifies the Read/Write Head with which to communicate.
1: Read/Write Head 1
2: Read/Write Head 2
Read area start address
Specifies the first address from which to read data from the Data Carrier as a four-digit hexadeci-
mal number.
Specifiable range: 0000H to FFFFH
No. of read bytes
Specifies the number of bytes of data to read from the Data Carrier as a two-digit hexadecimal
number. Up to 256 bytes can be read with one command.
Specifiable range: 00H to FFH (The maximum of 256 bytes will be read if 00H is specified.)
• ASCII specification: 256 bytes (256 characters)
• Hexadecimal code specification: 256 bytes (512 characters)
End code
Indicates the results of command execution. An end code of 00 is returned for a normal end.
Refer to
for more information.
Read data
The data read from Data Carrier memory. The number of characters will be the same as the num-
ber of read bytes for ASCII data and twice the number of read bytes for hexadecimal data.
