ILDA cable specs

[dnar]

Hi All,

One thing that google and this site have not been able to answer for me is the build details of ILDA cables,

Do you need seperatly screened cores for each axis/colour modulation to reduce crosstalk or is ok to use a multicore cable with a single overall shield?

Many thanks in advance.

Hi

I have used many "standard" computer cables (DB25) up to ten meters in length and have had no trouble. For my longer runs I use twin shielded (balanced) multicore (Microphone snake cable).
Although these days I mainly use the Network system.
The good news on the computer cable is its cheap easy to use and replace. Not too sure how "long" you can have these up to but at ten meters no issues at all.

The old spec that has never made it on line calls for 120 ohm or 600 ohm impedance differential twisted pair, with at least a outer shield. Fully shielded individual pairs are optional.
I have it some place, if you really, really need a copy. They specify a couple of different types of Belden cable as examples, but it is not critical at all for runs to say 20 meters or even more.

Thanks Guys. I'll start with some old computer cables I have laying around.
