All Options Disabled
Laser Redundancy Check Enable
Laser Connection Detection ON
Continuous Read Mode
Trigger Latch Mode On
Values of n: 0 . . . 15
* Default
The default value of <n> is 8.
Note: This function allows several functions to be selected simultaneously.
To determine <n>, choose the wanted functions and add the corresponding
binary values.
Continuous Read Mode Example
To enable the continuous read mode, send the following escape sequence:
Esc – y 4 R
When enabled, the laser scanner is turned on when triggered, but is not shut
off when the trigger is released. Instead, the laser continues scanning until
either the laser shutoff delay period has elapsed or a good read occurs.
When this mode is disabled, the laser is shut off immediately when the
trigger is released.
Note: This must be enabled when using a Catalog No. 2755–L2 scan head.
