Testing Communication using NON PORTABLE mode
To test communication as a USB HID Keyboard, go to
Chapter 3
:
Non Portable Mode
for detailed instruction on how to use NON
PORTABLE mode to establish communication between the TriCoder and the host computer. The key to testing communications is to
keep it simple – you don‟t want to have to determine whether it‟s your software or the TriCoder causing a problem.
There are two special settings to accommodate older computers that may have trouble accepting USB HID Keyboard data from the
TriCoder in the default format.
The first setting is a
USB ENUMERATION DELAY
. This setting is adjustable from
0-9
seconds to delay the data from uploading to
the computer until the enumeration is successful. If you are missing data at the very beginning of a file upload you can add a delay to
the enumeration to solve this.
The second option is the
USB HID SPEED
. This setting by default is set to
FAST
and offers our fastest upload that will work with
most modern PC‟s including any computer that runs Windows 7, Vista, or XP. The other option is to set it to
SLOW
for slower
Windows machines that run older Windows versions like 98SE. If your software or computer is having trouble keeping up with the
FAST
setting you may hear beeps or a screech from the computer after a large number of records have uploaded. With any machine
that does this your data may be incorrect or incomplete and you will need to select the SLOW HID Setting for uploading.
In some cases you may need both a
USB ENUMERATION DELAY
and the
SLOW HID SETTING
enabled to ensure correct
uploading of your data on older PC‟s running old versions of Windows.
There is also a setting for foreign key support that sends all characters to the computer in their ascii key values or “ALT” key
sequences. You can change the
USB HID ALT OUTPUT
from
OFF
to
ON
to switch this mode if you are using a foreign keyboard
in your Windows setup and your data isn‟t coming across correctly from the TriCoder in HID Keyboard data upload or non portable
mode.
An example of this is if you scan a bar code, or key in “A” on the TriCoder, and upload it with your computer keyboard set as a
“English - US Keyboard” you will always get an “A” sent to the computer. However, if you choose another language or country
keyboard like “French (France)” you may get a different character (e.g. “Q”). By changing the
USB HID ALT OUTPUT
to
OFF
the
TriCoder will send the correct “ALT” sequence to the computer regardless of your keyboard settings.
