Back Input and Connector Panel
Let's start top left (as usual). First is a small mini-USB type connector for the service port. Then comes the SDI port (a BNC connector). SDI let's you run live Hi-def video, say from a pro TV camera, or other device, directly into the projector where it can be displayed.
Two RJ45 connectors (Ethernet connectors) are next, the first is the LAN connector for your local area network, the other is the HDBaseT connector, which can carry HDMI with audio, plus command and control, and networking information to distances of over 200 feet. In other words, this Epson is built to handle hi-def sources even at great lengths.
HDMI comes next and the similar, but different connector for DisplayPort (more of a packet type interface - it works with data much the way the internet works). Far to the right is the good old "stuff", consisting of an S-Video connector (DIN), a composite Video (RCA jack), and two audio in jacks - left and right (white and red RCA jacks).
Now we'll swing back to the second row of connectors, from the left you'll find a standard analog computer input, with the traditional HD15 connector. After a space, to the right are two stereo mini jacks for Audio in 1 and 2.
Below these, you'll find five BNC connectors in a row for component video RGB with sync.
We're almost done.
To the right of the Computer input is the traditional Monitor out (DB15), and below it, a DB9 RS232 serial port for command and control (old school). That's almost it. a bit to the right of that Monitor Out is a mini-jack for the stereo audio output. The G6900WU projector may not have speakers but it will allow control and routing of audio to that output, to be fed to an external sound system.
As you can see, the G6900WU is extremely well endowed. The G Series line-up, overall, is similar, with some having one or two less inputs. The G6900WU, however, is the only one that supports SDI, or I should say: HD-SDI.
The Epson projector is obviously well equipped even for a larger venue projector, and especially so for one so small and light (relative to 6000 lumens). If I had one thing, however, that I would immediately change, it would be to have a second standard HDMI input jack. That would be more convenient in some installations. Of course there are other ways to get a second HDMI signal into this projector.
