Discrete I/O
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 Table A-2, “MS-3 Laser
Host Connector, 15-pin,” on page A-4.)
Serial Cmd:
Default:
<K720,output on,polarity,pulse width,number to output on>
Active Low
Options:
0 = Active High
1 = Active Low
Definition:
Sets the time in 1mS increments that the discrete output remains active.
Serial Cmd:
<K720,output on,polarity,pulse width,number to output on>
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 associated output.
Usage:
Serial Cmd:
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.
