Origo - heres the deal...

[Harry Clark]

And my Media Logic speed control was singularly the best ROI of any piece of equipment I have bought before or since. It cost $800 (I think) and made me $175 every working day throughout the 1990's. Had the Arri cable, the PV cable, the Aaton cable.
I sold it shortly after I sold my SR1 for... $800!
Thank you Doug.
Cheers,
Harry

Damn, I knew we should have rented them! Thanks Harry.

Ah Doug... i forgot about your past. another smart cookie

Bottom line really is....take special care with VF 'lemo' cables.
Some duds slipped in circulation (happens) which can blow power supplies (cost $300-800). Normally sparks a product recall.

Next thing is who pays?
Firstly, put equipment/production insurance to one side.

- Equipment comes in to Red and circuitry related to GPIO is damaged.
- Red tech can prove that damage was caused by faulty 3rd party equipment attached to GPIO output and nothing else.
- Result is owner pays Red as it's not covered under warranty or their terms & conditions.
Note: under View Factor's terms & conditions - limitation of liability* or tort, there is no exclusion to liability resulting from 'direct' damages caused by VF equipment.
The VF terms & conditions also states liability shall not exceed the amount paid for the VF equipment.

cheers, Dave

Curt,
The Origo we have is working fine. An early model purchased with all size cables and ALL ARE GOOD!
Hey, one more thing..having been to your shop. I can attest for the way you do things. You have the utmost of integrity not to mention ingenuity. Keep it up. Just put the Inclino and Impero on its first job last week, more to come.
David

Listen carefully to doug.... making up lemo type cables is VERY difficult and subject to several assembly errors. I think the reversable issue is not limited to look alike lemos but that actual lemos can also be assembled incorrectly. The issue here may be misassembled cables and not which brand is used. I have used look alike lemos and properly assembled they did not reverse and were completely reliable. Curt best to ya, I'd be sure your cable assemblers are totally trained and the cables are assembly checked by a second person each time!!

I have suggested an in-line circuit protection device that we can purchase so we can use the Origo with peace-of-mind. The idea would be to buy the device and a second Lemo cable and plug the unit between the Origo and the camera to protect against a short-circuit. Is this feasible? Prehaps it could be used on other devices. Even at $100 it would be worth it.

We're working on something like that

Awesome. Can we pre-order? Would like to get in line early.

Genuine Lemo cables are pretty hard to assemble incorrectly. The ceramic insulator that holds the pins has a raised key that fits into a cutout on one of two half shell pieces that enclose the connections. If the key and the cutouts are not aligned, the shells don't close and it wont slide into the connector body. If the two are aligned and it does slide in, it still wont seat down properly unless it is twisted round so the notch on the shell keys in with another notch inside the body. The strain relief collet will not bolt down if this is not done properly.

It is obviously possible to cause shorts or connect the cables up incorrectly, but I find using the right size cable, tweezers and a small iron makes assembling these connectors fairly simple.

Angled connectors however are an absolute nightmare to assemble, especially in 0B size.

There is no way that assembling the shell incorrectly could cause the twisting problem seen here, as the key is part of the shell and has nothing to do with the way it is assembled.

Lemo do offer connectors in different key types. Most common is the G type which is when the key block is aligned with the red dot on the connector. The key is denoted by the letter at the end of the three letter part code, such as EGG, FGG etc. There are other keys such as J and A which have keyblocks in different locations, so it could be one of the 'lemos' is supposed to be a J or A key plug and its poor tolerance and construction is allowing it to fit the G socket anyway.


See page 21 of the current Lemo catalogue to see the differnt key types that are available.

Hi Pete,

True, IF done correctly and with the correct tools....

With the LEMO B Series, I have seen some instances where the outer shell has been rotated around the inner locking mechanism where the insert keying takes place...

The outer shell CAN rotate around the lock springs if you don't watch what you are doing, and are not using the proper LEMO tools. There are TWO keying systems in the LEMO B, one for the insert, the other for the shell to mate with the receptacle.

The insert key HAS to line up with the shell key. If they don't, then stop there and fix it!!! As the insert will not be oriented correctly. Very easy to miss for the uninformed.
