HD wiring upgrade to a Master sled

Hello,

How difficult/ what is the process for re-wiring a Master series sled to support HDSDI? Maybe even swap out the 4 pin HiROSE to be all 2 pin LEMOs and throw on another Aton plate to the front of the K section too.

I plan on keeping this sled for a few years so upgrading it is not a option, just wanted to try and bring it up-to-date.

It all seams like a challenge over my head, is there anyone to be recommended for this in the LA area? Trying to know what i am getting into before I make the first step.

 

Thanks.

Well you can not upgrade an SD signal. The quality of the wire is physically too weak. You need a 75 ohm wire. I suppose you could run a hyper thin one Dow yourself (post extended first) and terminate both ends with a BNC connector a cheap solution.

But I highly recommend just going to see Terry West.

He's the man and can 1000% help you out.

There are 2 composite video signals cable inside the post with connectors.

They are good enough for HDSDI signal.

Just disconnect them to signal processing and splitter.

Connect both ends to BNC connectors then you have 2 HDSDI connections.

 

Here is how;

Keep all the connections from stage-to-post and post-to-bottom-electronics.

Inside the nose, keep the one that connect to BNC. Disconnect the other cable that connect to the 4-pins Hirose, cut off the signal splitting cable to the back-stage 4-pin Hirose. Drill a hole on the side of the nose for a second BNC, then solder the video cable to that BNC.

Remove the cable which connected to the 4-pin in the bottom electronics. Cut off all connections to composite signal processing.

Build a new BNC, then solder that cable ends to.

DONE. you have 2 separated solid direct HDSDI connections.

Mines are fine with 3G-SDIHD

 

Have fun,

 

Ken Nguyen.
