5.2.1 ID Number
Add the ID Number (4 digits) at the beginning of the decoded data. It can be
used for multi-configuration with the reader. Host computer can recognize the
data which reader has sent. The ID is set by the serial command “BTID=xxxx”.
“xxxx” is the ID Number. To disable this function, send the command
“BTID=0000” to the reader.

Add the Warning Information for monitoring the decode condition at the
beginning of the reading data. This setting is enabled by sending the serial

interface.
e.g.1)
CHKBCR=0,1 : Added only for RS232C.
CHKBCR=1,1 : Added for both interface.
CHKBCR=1 : Same as “CHKBCR=1,1”.
CHKBCR=0 : Same as “CHKBCR=0,0” (Disable).
Output format: (CcccEeeeDddd)
ccc: Contrast Information for the captured image
eee: Unused Error Correction rate
ddd: Decodability margin
e.g.2) Good Read
Data output: (C082D091E100)A123456A
Calculate contrast value of a symbol including quiet zone. The decoder
determines a rectangular area for the symbol and calculates the contrast
value from its brightness level. If there are multiple symbols, the calculated
value is for the first decoded symbol.
e.g.3) No Read
Data output: (C000E000D000)BR
