RS-232 programmable selections are used by both the primary and secondary interfaces. Changing an RS-232 parameter (e.g., baud rate or parity), while in primary or secondary mode will affect both interfaces. If you want to change the RS-232 settings, refer to the Connecting the Imager with RS-232 Serial Port section on page 1-6. RS-232 Interface Secondary Trigger Mode Manual Trigger: You must press the imager trigger to scan. When not scanning, idle power is maintained. Default = Manual Trigger. * Manual Trigger Automatic Trigger: The imager scans continuously at full power. Automatic Trigger Presentation Mode: The LEDs are off until a bar code is presented to the imager. Then the LEDs turn on automatically to read the code. Presentation Mode uses ambient light to detect the bar codes. Presentation Mode Hands Free Time-Out The Automatic Trigger and Presentation Modes are referred to as "hands free" modes. If the imager's trigger is pulled when using a hands free mode, the imager changes to manual trigger mode. You can set the time the imager should remain in manual trigger mode by setting the Hands Free Time-Out. Once the time-out value is reached, (if there have been no further trigger pulls) the imager reverts to the original hands free mode. Note: If you change the time-out duration for the secondary interface, the duration of the primary interface will also be changed. 6 - 2

RS-232 programmable selections are used by both the primary and secondary
interfaces.
Changing an RS-232 parameter (e.g., baud rate or parity), while in
primary
or
secondary mode will affect both interfaces.
If you want to change the
RS-232 settings, refer to the
Connecting the Imager with RS-232 Serial Port
section on page 1-6.
Secondary Trigger Mode
Manual Trigger:
You must press the imager trigger to scan.
When not scan-
ning, idle power is maintained.
Default = Manual Trigger
.
Automatic Trigger:
The imager scans continuously at full power.
Presentation Mode:
The LEDs are off until a bar code is presented to the
imager.
Then the LEDs turn on automatically to read the code.
Presentation
Mode uses ambient light to detect the bar codes.
Hands Free Time-Out
The Automatic Trigger and Presentation Modes are referred to as “hands free”
modes.
If the imager’s trigger is pulled when using a hands free mode, the
imager changes to manual trigger mode.
You can set the time the imager
should remain in manual trigger mode by setting the Hands Free Time-Out.
Once the time-out value is reached, (if there have been no further trigger pulls)
the imager reverts to the original hands free mode.
Note:
If you change the time-out duration for the secondary interface, the
duration of the primary interface will also be changed.
