Function Descriptions
Usage: Sets the mask position mainly according to the
optical.
Note: Set the mask size to sufficiently cover the mask
object. In addition, ensure that the settings are
set on the WIDE end.
Mask height

Example) Setting the mask position according to the
following parameters
Aspect ratio
Mask Number
Mask Width
Mask Height
Mask transparency

Pan Angle*
Tilt Angle*
*For PAN Angle and TILT Angle, the angle parameters
that were sent in advance to the camera by PAN/TILT
Degree Command will be reflected automatically.

Note: Set using a pan angle range of 0°-360° and
a tilt angle range of –180°-180°. (Refer to the
diagram below)
The angle is displayed as 12 bits and
divided into 4-bit units when increased by a
magnification of 10.
In addition, when setting a negative tilt angle set
the tilt angle code bit f to 1.
Example) Setting the mask angle according to the
following parameters
Aspect Ratio

Pan Angle
Tilt Angle
Pan Angle:
1350 → 0x546 → q = 5, r = 4, s = 6
Tilt angle sign bit:
If the tilt angle is positive → x = 0
Tilt Angle:
100 → 0x064 → t = 0, u = 6, v = 4

According to the setting above, if the tilt angle only is
set to -10 degrees the following codes are transmitted.
