Wrong Read Format
There are several different ways the CLV can indicate if the scanner gets a wrong read (no read or no match situation):
- Separator(1) only
- Error String(2) only
- Separator(1) and Error String(2)
- No Error String or Separator
(1) The separator may be defined in “Host Interface; Output Format”.
(2) The error string may be defined under “error string” and will set “count of characters” to 00.
Status 5 Output
Used when the scanner is able to read something, but cannot fulfill the minimum number of multiple reads the user has pro-
grammed. The user may select between “error string,” in which case the CLV will output an error string, or “code string,” in which
case the CLV will output the code it was able to read.
Check Max. No. Codes
If “Check Maximum Number Codes” is activated, the CLV will respond with a no read situation if the number of bar codes read
exceed the “Max. No. Codes” value entered in the Code Configuration section. If the error status (ST) statistic is activated, an “A”
will be transmitted to indicate this condition.
Note: The CLV must be programmed to transmit at “End of Clock Pulse”.
HOST PROTOCOL
Defines handshaking schemes, when data is transmitted and in what order from the CLV to the host device. Also the network
mode can be activated. Refer to Appendix C, Table 4 for defaults
