Scanning
Pulse Trigger
The laser is enabled and decode processing begins when the trigger line is activated.
Decode processing continues regardless of the trigger line until a good decode occurs, or
until the Laser On Time expires. The laser is disabled once decode processing is complete.
The next decode attempt will not occur until the trigger line is released and then reactivated.
Pulse
Blinking (MS-120XFZY Versions Only)
The laser blinks at a 25% duty cycle (reduced to 10% after 30 seconds of inactivity), until a
bar code is presented. When a bar code is presented, the laser remains on until either the
bar code is decoded or removed, or the session timeout expires. Once the bar code is
decoded, the scanner will not decode it again until the bar code is removed.
Blinking
Host Trigger (MS-1204 and MS-2204 Versions Only)
The laser is enabled and decode processing begins in response to an SSI Start Decode
message from the host. Decode processing continues until a good decode occurs, an SSI
Stop Decode message is received, or the Laser On Time expires. The laser is disabled
once decode processing is complete. The next decode attempt will not occur until the next
Start Decode message is received.
