Thought I'd start a new thread on this to see if I reach a different group of readers.

In my ignorance and perennial optimism I bought three Omron servo drivers very cheaply from eBay only to later discover that they only accept an analogue control signal. In my defence I did Google the model number and even posted a link here, but I couldn't find any information indicating the drivers were analogue and no one else noticed either.

So I now have three drivers and a couple of cracking little servos that would run my machine very nicely if only I could tell them what to do. The easiest solution is to bung all three back on eBay and cut my losses, but they work really well and before I do that I'd like to at least explore the possibility of driving them from a step/dir to +/-10 converter.

Any suggestions - especially if they're available on this side of the pond would be welcome.

Thanks David
