Example of calculation of BCC
Use to detect data error due to noise in data communication between a host device and antenna. BCC is one-character data that XOR of
every data was executed per character in a range from DA to ETX. For details, refer to "JIS5001 Character Configuration on Transmis-
sion Line and Horizontal Parity Usage".
An example of calculation is described below.
Example: ID Code Read, Single Trigger
Note: "h" is a hexadecimal notation.

Name
Description
DA
Destination (host device) station number "80" to "89".
SA
Source (antenna) station number. Operation mode "00" to "31" (initial value is "00"). Setting mode
"99".
Command Code
Returns a command code of sent command.
Termination Code
Responds the result of command execution as a termination code. For the termination code, refer
to the termination code list in Section 5-10.
Data
Responds a response number, ID code, read data, etc. For details, refer to the formats of com-
mands after Section 5-7.
