Common Lens
Cheetah1 camera only supports P-Iris, and does not support DC-Iris Auto Aperture.
Serial Port
Cheetah1 camera has 2 available serial ports.
The serial port names in windows are COM3 and COM4.
(Note: The serial ports in Woodpecker1 are named COM5 and COM6)
COM1 reserves a serial port for the camera, for the internal debugging of the ROSEEK。
Since COM3 and COM4 are transferred from internal USB, the names of COM3 and COM4 may change, due to the characteristics of USB.
Therefore, it is recommended to open the serial port by using the method in the attached file to avoid the trouble caused by the name change.
Serial port open example：File:Open serial.rar
