No problem with small ground loop problems.


In your opinion would the D512s be reliable or should I go belt and braces with the D1024 as that has the optical isolating protection?

I don't want another failure live on stage, but at the same time I want to know if the D512s is likely to blow like the previous 2 USB Cables?

Many thanks

We think it will always be possible to blow a DMX interface.
We never tried but with 110/220 AC volts in the DMX line, we are not 100% sure it will resist a long time.

If your DMX line is really unsafe, you can insert a DMX isolator device between our DMX interface and the DMX line. Then a problem will first burn the external DMX isolator and this will protect our DMX interface.

Thank you for your reply, much appreciated.

Still don't understand how an Earthed Laptop connected to 2 Earthed LED Pars, powered with an Surge Protection power strip all PAT tested, still blow 2 of your your Interfaces with 2 different laptops?

Would the D1024 offer me better protection than the D512s?

It concerns me with having to shell out over £300 for the possibility it could blow again at anytime live on stage during a show? Granted it was with your earlier USB Cables I'm guessing that's why you have discontinued them hence why I'm purchasing a third device.

I'm struggling to find an external isolator, so must be a rare thing to happen, even though it's now happened to me twice within a year.

Are there hardwear issues we are not aware of?
I need to make a purchase ASAP to replace my dead interface.

Could you please tell me if I am better protected with the D1024 even though I certainly won't be using 1024 DMX channels

Many thanks
James

In the past, we saw some returned "Cable" because of electrical problem coming from the DMX line.
We got 0 return for electrical problem reason with the interfaces D512S, D1024 and Rack1024.
That is all we can say.

Excellent! thats certainly reassuring.
D512s will certainly suffice.

Many thanks for all your help
