No Decode Timeout - Microscan MS-3 User Manual

No Decode Timeout

Usage: Useful in many tightly controlled applications requiring a read cycle to
end before the next object appears.
Definition: The duration of the read cycle as measured from either the beginning of
the read cycle or from the last decode.
Serial Cmd:
<K220, 0,no decode
Default: 2 (seconds)
Options: 1 to 4095 seconds
a. The first parameter is always a zero(0) and does not change.
The MS-3 CCD times out if no symbol is decoded during the No Decode Timeout
period. If a symbol is decoded before the timeout expires, then the timeout period
starts over again.
No Decode Timeout only applies to Edge, Serial Data, and Serial Data and Edge
trigger modes.
In Single symbol mode (<K222,1>), No Decode Timeout is the maximum amount of
time the reader will attempt to decode after a trigger is activated.
In Multiple symbol mode (<K222,0>), No Decode Timeout is the time in which there
are no decodes, not the time since the trigger went active. That is, if the reader contin-
ues to decode symbols in front of it, it will not exit the read cycle unless the time
between decodes exceeds the time set in No Decode Timeout.
For Level trigger mode, the read cycle ends when the trigger falls, or a symbol is
decoded and output in single-symbol mode.
