Disable Auto
Switch
0: Enable the auto switch functionality for sensor orientation. Find sensor will
work only when this is cleared to zero.
1: Disable auto switch functionality so that the sensor orientation can be
forced remotely. This bit must be set to one before bit 0 and bit 1 can be
changed.

Minimum contrast: Minimum contrast required to accept an edge in contrast
mode.
Default value is 32.

Static Threshold
0: Static thresholding algorithm
1: Dynamic thresholding algorithm
* A previous version of the firmware used all eight bits for contrast. The actual contrast value can only
change from 0 - 100 on the display. The latest version would allow remote input between 0 and 63.
Sensor Brightness Command Register
Remote Light Control (RLC)
Bit 15 on register 2 has to be set to 1 to allow remote control of LED brightness to take effect. If this bit is
cleared to zero, changing any of the other bits in register 2 and 3 would have any effect on the LED
brightness.
Remote Brightness Limit (RBL)
Bit 14 on register 2 allows the user to set brightness limits remotely. In normal operation the brightness of the
individual sensors are allowed to vary from 4% to 100%. However, power users can change that limit
through ethernet by setting this bit and writing values to the two remaining 7-bit registers.
Maximum and Minimum Brightness Limit
The maximum value for the brightness of the LEDs can be written to bits 13 - 7 while the minimum value can
be written to bits 6 to 0.
Note:
These maximum and minimum limits are for both the sensors even though the brightness for
individual sensors may be different. The upper limit cannot be smaller than the lower limit value.
Note:
If bit 15 is not set (or cleared to zero), this will have no effect.
Note:
The limit value set through ethernet can change from 0 to 125 while the limit value set from the
controller can change from 0 to 100.
Note:
The limit will take effect even when the brightness is changed manually as well as if allowed to
change automatically.
WARNING:
When the ethernet connection is removed or disabled, the limits will be set permanently on to
the controller settings. So if the controller would ever be used for standalone operation make sure to rewrite
the lower limit to 5 and the upper limit to 125.
