13W3 Cables
	13W3 is an analog video interface connector used primarily on Sun Microsystems and Silicon Graphics Workstation. The connector contains 10 standard signal pins and 3 coaxial pins. On the computer side, the pins are female but the coaxial connectors are male. The coaxial carry the video signal split into red, green/gray, and blue; the standard signal pins carry four grounds, three “sense” pins used to communicate with the monitor, vertical sync, horizontal sync, and a composite sync signal. The 13W3 connector can be converted into a standard VGA connector using cables and adapters that commonly available. This allows modern multisync monitors, which are common on today’s computers, to be used with these workstations. Likewise, as many newer Sun Monitors support multisync, similar cables can be used to connect them to modern computers.
