APPENDIX J: TROUBLESHOOTING 111
SYMPTOM
: When I scan a barcode, odd behaviors occur, such as different applications seem to be
invoked in my system, and/or special characters are displayed in the application unexpectedly.
POSSIBLE REASON SOLUTION
In HID mode, the CHS will only properly
read printable ASCII characters. Non-
printable ASCII characters or extended
characters cannot be interpreted by the
scanner. Printable ASCII characters are
numbers between 0x20 and 0x7E, and any
ASCII characters that fall outside of this
scope are considered as non-printable.
Use the SocketScan 10 SDK to develop a custom
application that supports non-printable ASCII characters.

SYMPTOM
: When I press the Shift, Caps Lock or Ctrl key on my keyboard, it affects the data output
from my CHS to my computer.
POSSIBLE REASON SOLUTION
You are using the CHS in HID mode as a
Keyboard class device.
Determine how your computer implements HID keyboard
devices.
SYMPTOM
: When I scan some barcodes with the CHS in SPP mode, the data is truncated or some
characters are corrupted.
POSSIBLE REASON SOLUTION
The barcode data has illegal characters.
SocketScan 10 is designed to read ASCII
characters between 0x20 (Space) and 0x7F.
If you have a truncated barcode, you can view the raw
data without any conversions by using the Test option of
Scanner Settings, with hexadecimal format selected. If
you need to scan data that is not 7 bit ASCII (e.g., Double
Byte, MultiByte or UNICODE for Kanji, simplified Chinese,
etc.) use the SocketScan 10 SDK.
