Hello,

We need a multi-channel version of this USB isolator......

USB isolator:
**broken link removed**

We could just buy several of the isolators, but they are expensive.
Therefore, we are wondering if there is a unit that we could buy that will take in several USB inputs, then time-domain multiplex them together –so that it can be ported through one USB lead, and then be sent through just one USB isolator?
 

Thanks
I presume we only need one of those if we use a USB hub to take our three USB channels to...then we would go from the hub, through the isolator, and through to the PC?...do you know how we woudl split the datastreams back aprt again at the other side (PC side) of the isolator?

do you know how we would split the datastreams back apart again at the other side (PC side) of the isolator?

The question sounds confused. The bus root is a single host controller. The controller driver software splits the data streams.

Thanks, we are porting three signals from three units back to three instances of realterm on our pc (and we need the expensive USB isolator for each datastream) .....we are wondering how, if it is multiplexed.....how each of the realterms is going to know which is the stream that it should be looking at............will we actually need three PC's to do this?
 

You have apparently used USB on your computers up to now without thinking. What you are asking for is just the regular case of multiple USB devices connected to an USB host (e.g. PC) through hubs. The USB jacks of your computer are usually downstream ports of a root hub built into the motherboard.

Presumed the device firmware and respective PC driver software complies with the USB specification, you can easily connect multiple devices simultaneously and communicate to it by multiple Realterm instances.
