USB Guide Port Interface (GPUSB)

Autoguiding requires a means for a computer to send guiding signals to a telescope’s mount. For most mounts, especially the entry-level ones, a separate device can be used to enable the computer ‘talk’ to the mount—an example of which is a USB Guide Port Interface or GPUSB.
