USB Transmission Speed Parameters
Use the following parameters to speed USB data transmission:
USB Polling Interval
- When using more current USB systems, use this
parameter to set a lower interval in order to increase data transmission speed.
Quick Keypad Emulation
- When configured as a USB HID keyboard device,
use this parameter to increase the data transmission speed of a mix of both
printable (7-bit) and full (8-bit) ASCII characters.
USB Polling Interval
This option speeds data transmission for all USB devices except CDC. Scan a bar
code below to set the polling interval. The polling interval determines the rate at
which data can be sent between the scanner and the host computer. A lower
number indicates a faster data rate. The default value is 8 msec.
Changing the polling interval re-initializes the scanner.
CAUTION
Ensure your host machine can handle the selected data rate. Selecting
a data rate that is too fast for the host can result in lost data.
