Chapter 4 Read Cycle/Trigger

MS-880 Industrial Long Range Scanner User’s Manual 4-9

4–Read Cycle/Trig-

Trigger Filter Duration

Good Decode Reads

Note: When setting up, be sure to determine if the scanner’s scan rate is capable of

scanning your longest label the required number of times.

Definition: Trigger Filter Duration can prevent trigger bounce from falsely trig-

gering the scanner by limiting the time in which trigger pulses can be

received.

Usage: Trigger Filter Duration is useful where trigger bounce could cause

false triggers.

Serial Cmd: <K200,trigger mode,trigger filter duration>

Default: 320 (x 31.25µs = 10ms)

Options: 0 to 65535 (corresponding to 0 to 2.048s in 31.25µs steps)

Definition: The number of decodes (from 1 to 31) required per label before a

label’s decoded data is sent. It requires the scanner to successfully

decode a label a designated number of times (not necessarily consecu-

tively) before it is sent. If it doesn’t achieve the number of good reads

during the read cycle, then a noread will be sent.

Note: Higher settings will decrease throughput speed.

Usage: This is a very useful feature to increase reliability of reads for symbolo-

gies that do not have internal error checking such as Pharmacode.

Serial Cmd: <K221,decodes before output>

Default: 1

Options: 1 to 31
