Denso BHT-400-CE Reference Manual page 87

The BHT-400B supports universal product codes, Interleaved 2of5 (ITF), Codabar (NW-7), Code-39,
Code-93, Code-128, Standard 2of5 (STF), and MSI. It can also read EAN-128 if Code-128 is specified.

Specify a code from one of the following.
Code Barcode Type
A EAN-13 (JAN-13), UPC-A
B EAN-8 (JAN-8)
C UPC-E
If the code is omitted, it will be possible to read any of the above universal product codes.
st
The 1 character and 2
be a numeral between 0 and 9 (inclusive). If a question mark (?) is specified for the 1
character, it is treated as a wild card.
"supplemental" refers to the reading of an add-on code. Specifying an S for add-on enables the BHT to
read barcodes with an add-on code also.
[Ex.]) To enable the BHT to scan EAN-13 with 1
add-on code:
[VB] MyScanner.RdType = "A:49S"
[C#] MyScanner.RdType = "A49S";
[Ex.] To enable the BHT to scan EAN-13 and EAN-8 only:
[VB] MyScanner.RdType = "A:A,A:B"
[C#] MyScanner.RdType = "A:A,A:B";
