Mac OS X VGA2Ethernet user interface 

This chapter describes common functions and features of the Epiphan VGA2Ethernet 
user interface for Mac OS X. You can use the Mac OS X version of the Epiphan 
VGA2Ethernet user interface to configure a VGA2Ethernet attached to the network 
and to record video captured by the VGA2Ethernet. 
This chapter assumes that VGA2Ethernet has been properly installed. To start using 
this chapter you should have:  

-

 

Selected a video capture workstation running Mac OS X.  

-

 

Successfully installed the Epiphan device drivers and application on the 
video capture workstation. 

-

 

Connected the VGA2Ethernet device. 

Upgrading to the Latest Mac OS X Software Version  

From time to time Epiphan makes new versions of all Epiphan frame grabber software 
available from the Epiphan web site. In most cases you can upgrade the Epiphan 
software on your Mac OS X video capture workstation by using normal procedures to 
download the latest version and install it without uninstalling the previous version.  

Note: Some versions of the VGA2Ethernet user interface do not install a shortcut on 
the Mac OS X desktop. You can drag the Epiphan icon from the Applications folder to 
your desktop or add it to the Dock after installing a new version of the VGA2Ethernet 
user interface. You may also need to delete older versions of the Epiphan icon.
