Setting the Camera Video Mode
Changing the video output mode of the Harrier HDMI Camera Interface Board can be done using an
external controller over the serial (TTL) interface.
Cameras usually start up in the same video mode that was set when the camera was powered down.
Immediately after power-up completes, the camera interface board can change the camera video
mode to a user chosen mode; this ensures that on application start-up the camera is always in a
known video mode. This is done by setting DIP switches 1 to 4 on the Harrier HDMI Camera
Interface Board as shown below. VISCA commands can be used at any time to change the camera
video mode (requires camera reset).

Table 1. DIP switch settings for selecting camera video output mode
Notes:
1)
“Default camera mode”: on power-up, the camera will start in the video format/mode that was
set/being used when it was last powered down. The video mode can then be changed using a
VISCA serial command, followed by a camera reset (there is also the camera hard reset in the
extended VISCA commands which will also serve this purpose).
