Since the key- in data from keyboard must pass through the
decoder, the cabling connections are correct if the keyboard
is functioning well.
Does the keyboard work.
Most notebook computers do not supply enough power to the
scanner. The symthom is commonly visible by lower good read
rate since there is no enough power to a support the scanning
operation.
Does Keyboard port supply enough power ?
Computer's BIOS has a feature related to keyboard typing speed.
Try to setup Intercharacter Delay' ( page ) to stimulate the effect
of the keystroke speed
.
Can your computer accept the data fast enough?
There are no industrial standareds for scanner interfaces cables,
even if they look alike and have similar connector. For example:
cables for keyboard & Wand Emulation are similar, but they
cannot be interchanged each other due to different Pin
assignments. Be sure your cable attaches correctly to the
matching connector.
The cable seems to connect properly but the scanner
cannot send data to host computer.?
Check the configuration setting of the decoded scanner and make
sure your decoder can accept the bar code format.
Are you using Wand Emulation mode with Code-39
output and is your decoder set up accordingly to
accept Code-39 data?
