280 QuickScan™ I QD21X1 / QM21X1 / QBT21X1
RS-232 Parameters
Intercharacter Delay
This parameter specifies the intercharacter delay between the end of one char-
acter 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 milliseconds.
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. Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Program-
ming Mode.
4. Scan the bar code: SELECT INTERCHARACTER DELAY SETTING on
page 36
.
5. Scan the appropriate two digits from the keypad in
Appendix D, Keypad
, that
represent 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 bar code to exit Programming
Mode.
This completes the procedure. See
Table 5
for some examples of how to set this
feature.

STEP ACTION EXAMPLES
1 Desired Setting
50ms 150ms 600ms 850ms
2
Divide by 10 (and pad with
le
ading zeroes to yield two-
digits)
05 15 60 85
3 Scan ENTER/EXIT PROGRAMMING MODE
4 Scan SELECT INTERCHARACTER DELAY SETTING
5
Scan Two Characters From
Appendix D, Keypad
‘0’ and ‘5’ ‘1’ and ‘5’ ‘6’ and ‘0’ ‘8’ and ‘5’
6 Scan ENTER/EXIT PROGRAMMING MODE
NOTE
If you make a mistake before the last character, scan the CANCEL bar
code to abort and not save the entry string. You can then start again
at the beginning.
