MS-804FZY and MS-904HS Integration Guide
Position at an Angle
Do not position the scanner exactly perpendicular to the bar code. In this position, light can
bounce back into the scanner's exit window and prevent a successful decode.
Triggering Options
Level Trigger (Default)
The laser is enabled and decode processing begins when the trigger line is activated.
Decode processing continues until a good decode occurs, the trigger is released, or 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.
Level
Continuous
The laser is enabled continuously and decode processing is continuously active. The
scanner can be configured to scan and transmit a bar code, and then not decode the same
bar code or any bar code for a set period of time. See
Timeout Between Decodes on page
7-16 to customize the application to the rate at which bar codes are presented.
Continuous
Note: This option is not recommended during scanner programming via
bar code menus.
