I have just started dealing with my (brand new) RS2. It is still on a stand for the preliminary lessons of use.

Yesterday I discovered a hidden connection at its rear panel, at the left side of the two HDMI jacks (the projector is on its feet, standing on a small table).
The connection has been nicely cover with a smal black plastic cover, secured with a simple screw. I remoned the screw and took the cover out and voila!

I took some photos of the rear panel with and without the cover. Can somebody tell me what this is?

The HD1/RS1 also has a panel covering a connector and DIP switches. I assume these have a similar use and AFAIK the connector is for JVC use during the build/test process. The DIP switches control certain aspects of the PJ and are adjusted to a different setting to allow new firmware to be loaded for example.

These sockets (they are two of them) are almost of the same size like the HDMI ones.

My mind goes to the new kind of Digital Conncetion (I really don't recall its name now), which is said to be used in the Pro world, intending to replace HDMI, since it does not require patent rights to be paid.

Could it be so?

P.S. 1:
As I said, I took some photos with my camera intending to post them, but although I saved them in my computer and reduced their size, I don't find the way to do it. What do I do (or don't do) wrong?

P.S. 2:
I apologize for my bad spelling of some words in the first post, but it was a very quick posting, before I leave for my office this morning.

its a gateway to another world

It is a magical HDMI...it allows the projector to have 100000000:1 contrast, 40000 lumens, and 4k resolution. Pretty slick. :D

dont look behind the curtain

It leads inside John Malkovich.

It is an RS232 connector used to do a software upgrade from a serial port of a PC. I did it once on a RS-1...

It's where babies come from, shh..... they have been lying to kids for years :)

The RS232 is not hidden. It is at the right side of the two HDMIs and it is at the immediate disposal of the user, for connection of the Pj with a computer.

However, I can see that the humor is not missing from here!:)

What you are seeing is the service port for the projector. There are a set of dip switches which allow you to put the firmware eprom into write mode . The connector above this with the pins is for an unknown purpose. Its probably just another com port for the eprom for a production line setup machine for factory calibration.

Thank you, Mr. D

You were really informative. This is all I wanted to know.

LOL! Good one Don!
