Problems with Samurai BNC cable on XLH1

Am having a problem connecting the Samurai to my Canon XLH1.

I have the Samurai mounted on the hot shoe toward the front of the camera.

One of the mini-BNC to BNC cables did not even fit on the Samurai.

The other one fit, but the connector has already separated from the cable.

In addition, my local electronics shop tells me that they only stock BNC cables of 3' or more. But I only need a total cable length of 21" from the mini input of the Samurai to the SDI output of the camera.

I'm surprised that Atomos did not supply the mini-cables with a 90-degree connector to prevent them from breaking so easily.

Can anyone tell me what they have done to successfully connect their Samurai to the XLH1?

Where did you find a 14" SDI cable?

Re: Problems with Samurai BNC cable on XLH1

Bob...have you spoken to the Atomos after sales Help Desk? They're very good responding to issues with their equipment.

Your statement confuses me: "One of the mini-BNC to BNC cables did not even fit on the Samurai."

Please don't take offense, I'm just asking, but you do know one end of the supplied cable is Mini-BNC/F and the other-end is a 'normal' BNC/M connector. Atomos made the cables that way in-order for people to purchase a short 'BNC' cable with both ends Female.

Atomos is 'investigating' a longer version with a 90-degree Mini-BNC/F and a 90-degree BNC/F on the other end. These cables will be longer ~75cm for direct connection from the Samurai to the camera, making the BNC 'extension' cable unnecessary. I hope this helps.

Re: Problems with Samurai BNC cable on XLH1

When Jeromy does demos, I've noticed that the cables he uses to connect the Samurai to a field monitor are not the typical RG59 type shielded cables. Instead he uses what looks like plastic coated wire instead of cable. Does anyone know what it is? I'm wondering if this is only good for short runs like in his demos or if you could use this wire for long runs of 100'.

Re: Problems with Samurai BNC cable on XLH1

Robert...The two supplied Mini-BNC to BNC cable are smaller diameter, plastic coated cables, electrically, they exhibit the same characteristics of 'normal' RG59 cable and are fairly robust. I just wish they where long enough to go directly from the Samurai with the appropriately sexed connector to the SDI male connector of my camera.

More(longer)cable equals more 'snagging' potential.

Regards,

J.

Re: Problems with Samurai BNC cable on XLH1

I was thinking of long runs of the HD-SDI signal back to the producer in a video village or to a production switcher in a multi-cam set up. I thought shielded RG59 would help prevent video interference over longer distances, but maybe that's my analog thinking in this digital world. I would certainly prefer to use that thin stuff if there's no advantage to using RG59. Do you know what it's called?

Robert...I don't know the specific spec for the cable, but this might help.
