Handshaking Control
The data interface consists of an RS-232 port designed to operate either with or without the
hardware handshaking lines,
Request to Send (RTS), and Clear to Send (CTS). Handshaking
Control includes the following options:
• RTS — RTS is asserted during transmissions. CTS is ignored.
• RTS/CTS — RTS is asserted during transmissions. CTS gates transmissions.
• RTS/XON/XOFF — RTS is asserted during transmissions. CTS is ignored. XON and
XOFF gate transmissions.
• RTS On/CTS — RTS is always asserted. CTS gates transmissions.
RTS/CTS Scan Control — RTS is asserted during transmissions. CTS gates transmissions and
controls enable and disable state of scanner.
RS-232/USB COM Parameters
Intercharacter Delay
This parameter specifies the intercharacter de
lay be
tween 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 milliseconds.
2. Divide the desired setting by 10 (setting is in 10ms increments). Pad the result with lead-
ing 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 Programming
Mode.
4. Go to page 45 and scan the bar code: SELECT INTERCHARACTER DELAY SET-
TING.
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 indica-
tion after the last character.
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.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit.
This completes the procedure. See Table 25 on page 249 for some examples of how to set this
feature.
