Samsung Galaxy Tab 30 Pin Dock Connector Pinout

is it possible to use the connector to wake up the tab? all of my physical buttons are dead so right now the only way to wake up my tab is by pluging it to any power source.

can use USB host cable + any accessory like a mouse, keyboard etc.

Question 1 / 2: Anyone know which pins are needed to support HDMI or more specifically which pins are used by the official Samsung HDMI adapter for Samsung Tab 2 10.1? Reason I am asking is the adapter is just to cumbersome with a HDMI cable, charger cable, and the 3" cable to the tablet so I want to build m-2-m 30 pin connector cable and rather not have to solder 60 connections! Lots of expense otherwise to figure this out by trial and error (ex. makertronic /samsung-tabbreakout is $20 and I need two but damn if I can find desired cable
Question 2 / 2: To the above, if I must use a 30 conductor cable, any ideas? Tried searching for 2+ hours without any luck - it needs to be thin, possibly foil, and suitable for purpose. I am near certain the 3" cable on adapter is not 30 conductors and probably no more than HDMI (19 pin?) is needed.
Thank you all

Looking at HDMI adapter pictures I suspect it has some schematic inside, not just bare "cable" because the adapter is quite massive. Also the pinouts I've seen have no mention about HDMI.
I suspect the HDMI is connected to USB host pins.

The MHL pins are most likely where they are getting the HDMI signal. This requires a bridge chip to translate between protocols.

MHL is a standard designed to allow a mobile device to transmit HDMI over a different connector it would already have. (Most often USB.) Samsung has diverged from the norm and has combined MHL in different ways on different products. The GS3, it was an 11 pin connector compatible with USB micro. On the Tabs, it's rolled into the 30 pin connector. Here's more info on MHL:

The spec can only be downloaded by becoming an adopter. Silicon Image makes some bridge chips, but don't have datasheets readily available on their website.

I know that this post is forever old, but I'm always frustrated trying to find the answer to lingering questions on forums. I came here hoping to find where I can purchase just the 30 pin connector itself. I'd like to roll my own dock with specific features for my Note 10.1 that I'd like to combine into a case. Yeah, I'll probably never get around to it, but it's fun to think about.

I bought my third party charge cables and OTG adapters from Chinese shops like dx.com. If you're looking for a cable to hack, places like that and eBay might be an option. Older Apple ipod cables will fit as well, but I think I read somewhere that Samsung reversed the pin order in theirs. I'm not adventurous enough to try swapping cables between the two myself.
