Character Frame Control is used to adjust the timing gap between bytes within one character data output by the scanner. Intercharacter Delay is a time delay
between data characters output by the scanner. These two parameters are used to synchronize data communication when : 1) the data transmission speed is too
fast, characters may be skipped; 2) multitasking operation system or host computers in a network may slow down the keyboard handling; 3) various notebook or
desktop PC systems require different timing parameter settings. Please always add one extra unit as a safety margin when adjusting these two parameters.
Intermessage Delay is a time delay between messages output by the scanner. Increasing this delay will help host applications process the incoming data on time.
The “Caps Lock Control” and “Key Pad Emulation” functions are only available for IBM PC/AT, PS/VP, PS/2 series personal computers and compatible machines.
If you select other host interfaces, these selections will not perform the above functions.
Please check the actual Caps Lock state in use while the software application is running. If the Caps Lock state is off, select the “Caps Lock Off” state, then the
scanner will perform normal data transmission. If the Caps Lock state is on, select the “Caps Lock On” state. If you select “Auto Detect,” the scanner performs
special transmission handshaking without changing the status of the Caps Lock switch.
