Parity / Data Bits
(none-8/odd-7/odd-8/even-7/even-8/space-7/mark-7)
“Parity/Data Bits” directs the CLV to transmit data words consisting of individual ASCII characters with selected numbers of data
bits, with or without parity check. When networking via RS 485 interface, data format is automatically set at “odd parity/7 data
bits” by selection of “Network Protocol” menu function. Combinations are as follows:
Stop Bits
(1 or 2)
Stop Bits directs the CLV to transmit data words consisting of individual ASCII characters with 1 or 2 stop bits. Default is 1 at
standard configuration. When networking via RS 485 interface, one stop bit is automatically set by selecting “Network Protocol”
menu function.
DATA STRING
The data string will structure the data output to the host device. The user can select certain parameters that determine what the
data string, made up of bar code data and diagnostic reading data, will look like. Refer to Table 4-2 for a description of the con-
tents and location of diagnostic reading data (contained in the header, the separators and/or the terminator). Figure 4-3 shows a
sample data string. Refer to the ASCII table in Appendix C for assistance in programming.

Header
(up to 10 (Refer to Figures 4-2 and 4-3))
The header can consist of up to 10 characters in any arrangement, or can be suppressed entirely by setting all elements to “00”.
If used, the header will always appear in front of the bar code data and the separator (if applicable). The protocol send start char-
acter under Host Protocol is the only character that is transmitted before the header.
Any characters from 01 to 7F hex and/or the reading diagnostic statistics MG (average reading evaluation) or CC (number of
codes) may be used. Refer to Table 4-2 for descriptions of the statistics and to the ASCII Table in Appendix C.
