•
CR & LF - Allow you to select where the cursor on a display terminal
returns to after it displays each decoded symbol. Selecting both CR & LF,
returns the cursor to the same position on successive lines after each
decode. If you select no control code, the cursor remains where it stopped
after the last transmission.
•
End-of-text <ETX>.
•
One or two characters, user-defined.
Prefix/Suffix (Synapse)
When using Synapse, the prefix or suffix appended to scan data for data
editing is set by scanning a 4-digit number (i.e., 4 bar codes) that corresponds
to key codes for various terminals.
Communications Delays and Timeouts
(Intercharacter Delay)
Select the intercharacter delay option matching host device requirements. The
intercharacter delay gives the host system time to service its receiver and
perform other tasks between characters. Select from no delay to a 99 ms delay
between the transmission of each character.
UPC A and E Preamble(s)
Three options are given for the lead-in characters of decoded UPC-A or UPC-
E symbols transmitted to the host device. Select one preamble for UPC-A
decodes and one for UPC-E decodes. These lead-in characters are considered
part of the symbol itself. The three options are:
•
a system character only
•
the country code and system character
•
no preamble
The system character is the digit printed to the extreme left of a UPC symbol.
The country code for UPC is always zero, and it cannot be transmitted without
the system character.
