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 transmissi
ons.
• 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 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 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
Mo
de
.
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.
