USB KEYBOARD

5.2.1

Keyboard Speed

This parameter manages the transmission speed of characters to the Host. A fast
Keyboard Speed allows rapid transmission of a great amount of characters (for
example 2D codes), but it might not be compatible with slower systems.
5.3

CODE SELECTION

5.3.1

Issue Identical Codes

This parameter manages the code transmission when more than one code
containing the same information is detected in a single scan.
All identical codes are transmitted to the Host when the parameter is enabled; if
disabled, only one of the identical codes is sent.
5.4

READING PARAMETERS

5.4.1

Safety Time

Safety time prevents the device from immediately decoding the same code more
than once. A timeout can be set up to 9.9 seconds before the decoder will accept the
same code. Reading is immediate if the code changes.
The safety time parameter is not applicable when all codes per scan is enabled or
when setting one read per cycle in normal (hardware) trigger operating mode.
