# Configurations before Using GigE Vision Cameras

Before using GigE Vision cameras, you should make sure that the cameras and the PC are on the same subnet, and that the Jumbo Frame functionality has been enabled in the Windows system.

Make sure that the cameras are powered on and connected to network.

   Jumbo Frame

   Receive Buffers

     Set the size of Receive Buffers. Increasing the Receive Buffer size improves receiving performance while costs more system memory.
