DIY BNC to 4pin LEMO Timecode cable

I need a timecode cable to go from a Zoom f8 to a RED camera, but to buy they are super expensive. So, I figured I'd just make one. It's a BNC to 4pin LEMO type.

However, I am having trouble finding a schematic that will tell me how to wire it up.

I know which is the ground, but other than that, I don't know which pin(s) to connect.

Any help?


*Also, will probably need the wiring for a 5pin LEMO as well (for ARRI cameras)

Even if anyone has one of those cables and just takes a ohmmeter to it and lets me know the lead configuration, that would be great...

SMPTE timecode uses the video standard of 75 ohm cable. But for short distances, it isn't really critical.
You may have to use RG-179 coaxial cable because the Lemo connector is probably too small for conventional RG-59
If you use RG-179 then you will need to use a BNC connector for RG-179

While I have made my own cables for over 55 years, and I am a great advocate of DIY cables, to be honest, I would rather buy one than make one.
BNC connectors are rather fiddly to terminate, even on larger RG-6 or RG-59 cable.
The miniature kind are that much ore fiddly. I would buy several extra just to allow for errors.
And those little Lemo and Hirose connectors are pretty fiddly to terminate, also.

It looks like you can buy a 1m long cable on Amazon for $30 I would buy rather than make in this case, but good luck.
