Lens Control Output for Iris, Focus, and Zoom
The external Lens Control outputs in BOBCAT HD-SDI cameras are directly
connected to the camera hardware, and operate in 6 or 12 volts. The maximum
average output current
MUST NOT
exceed 400 mA with all three motors
operating at the same time. Figure 2.12 shows the output external electrical
connection.

Custom GPIO (IN/OUT)
BOBCAT (HD-SDI models) has a provision for a high-speed custom general
purpose I/O – LVTTL (3.3 Volts) compatible. The maximum output current
MUST NOT
exceed 8 mA, and the maximum input current
MUST NOT
exceed 2.0 mA. This GPIO is not currently enabled. If your application
requires such configuration please contact Imperx for more information.

TEST IMAGE PATTERNS
2.10.1.
Test Image patterns
The camera can output several test images, which can be used to verify the
camera’s general performance and connectivity to the frame grabber. This
ensures that all the major modules in the hardware are working properly and
that the connection between the frame grabber and the camera is synchronized
– i.e., the image framing, output mode, communication rate, etc. are properly
