Noread
Definition: Activates a discrete output whenever the symbol data is not decoded
before the end of the read cycle.
Output Polarity
Definition: Sets the polarity of the discrete output.
When set to Active Low polarity, and an output condition from the
scanner is met, the output-1 pin on the scanner's 15 pin connector go
low for the time specified in Pulse Width. (See
Host Connector, 15-pin," on page
Serial Cmd: <K720,output on,polarity,pulse width,number to output on>
Default: Active Low
Options: 0 = Active High
Pulse Width
Definition: Sets the time in 1mS increments that the discrete output remains active.
Serial Cmd: <K720,output
Default: 50 (50 mS)
Options: 0 to 65535 (0 to 65.535 seconds). Divide the number entered on the
command line by 1000 for time in seconds.
Number to Output On
Definition: Sets the number of events (matches, mismatches, noreads, etc. as
configured by Output On) that must occur before activating the associ-
ated output.
Usage: For example, if Number to Output On is set to 3 and Output 1 is set to
Noread, then Output 1 will not be activated until 3 noreads have occurred.
Serial Cmd: <K720, output on,polarity,pulse
Default: 1
Options: 0 to 255
