Data Connections

Your OGMA camera has a fast USB 3.0 port on the back that you will use to connect the camera to a computer.

Even though the physical port is USB 3.0, the camera and the computer can communicate using either a data interface USB 3.0 or USB 2.0. The USB 2.0 data interface offers transfer rates of up to 480 Mbps and USB 3.0 offers transfer rates of up to 4.8 Gbps - that's 10 times faster.

To take advantage of the higher speeds of USB 3.0, make sure to plug the USB cable into a USB 3.0 port of the computer.

USB 3.0 ports are usually blue while USB 2.0 ports are black.

If you connect your camera to a USB 2.0 port in your computer, you might experience slow connectivity, dropped frames, images with bands, etc.

The following image shows an ASCOM connection with a cable plugged into a USB 2.0 port.
