Intercharacter Delay
This parameter specifies the intercharacter delay between the end of one character and the
beginning of the next. The delay can be set within a range of zero (0) to 990 milliseconds in
10ms increments. A setting of zero specifies no delay.
To set the delay:
1. Determine the desired setting in mi
lliseconds.
2. Divide the desired setting by 10 (setting is in
10ms increments). Pad the result with
leading zeroes to yield two digits. For example: 0 = 00, 5 = 05, 20 = 20, etc.
3. Go to page 16 and scan the ENTER/EXIT PROGRAMMING MODE barcode to enter
Programming Mode.
4. Scan the barcode: SELECT INTERCHARACTER DELAY SETTING.
5. Scan the appropriate two digits from the keypad in Appendix D, Keypad, that repre-
sent the duration which was determined in the
steps above. You will hear a two-beep
indication after the last character.
6. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming
Mode.
This completes the procedure. See Table 32 for some examples of how to set this feature.
Table 32. Intercharacter Delay Setting Examples
This feature applies ONLY to the Keyboard Wedge interface.
If you make a mistake before the last character, scan the CANCEL barcode to
abor
t and not save the entry string. You can then start again at the begin-
ning.
