Socket CHS Series 7 - Page 117

APPENDIX J: TROUBLESHOOTING 117
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. Learn more

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.
