16. Harrier Virtual Serial COM port: if the Harrier USB
SDK is installed, DIP switch SW1 [7] is ON and the
interface board USB port is connected to the PC, this
COM port will appear in the device manager COM/LPT
port list. It can be used to send and receive VISCA
commands in exactly the same way as an ordinary
serial COM port. As there is no physical serial
hardware, the serial port settings will not affect the
function of the Harrier Virtual Serial COM port.
Test Pattern
With no video input connected, a simple blue/gray screen is displayed (see Figure 12). You may see
this when the camera resets.
To display a static test pattern (see Figure 13), press the PGEN button on the Harrier Evaluation
Board.
Note: this button will only work if the 4-way cable is connected between the Harrier Evaluation Board
(J102) and the camera interface board (J2).

Analog Output
The BNC connector on the Harrier Evaluation Board will supply the analog video output from the
camera interface board. Note: this signal is generated by the camera and is not available on all
cameras. To enable this the camera must be set into PAL/NTSC output mode using the appropriate
VISCA command and a camera reset. When this video mode is set there will be no digital video
output from the camera (and the HDMI and USB video interfaces will not work).
