Nope, Not on what I was reading; but no matter, the advice I gave was still sound. -jg

My newsreader had organised that into a different thread so it was unseen when I queried the parenthesis portion.

It was posted 2 min after the first post. -- <http://www.cs.auckland.ac.nz/~pgut001/pubs/vista_cost.txt> <http://www.securityfocus.com/columnists/423> <http://www.aaxnet.com/editor/edit043.html> <http://kadaitcha.cx/vista/dogsbreakfast/index.html> cbfalconer at maineline dot net -- Posted via a free Usenet account from http://www.teranews.com

I don't know where you got the parenthesised portion of the text from but it was not in the original post of this thread nor any subsequent one from the OP. Original message was:-

You still have not said how fast you need to go! We use H11L1 optos (Schmitt, ~1us, 1.6mA ), as a good trade off between speed and price. -jg

What is high speed ? 110/9600/115k2/12Mbit/s ? What isolation requirements 0.5 kV, 2.5 kV, 110 kV or 400 kV ?
>1. Microcoltroller to Microcontroller at TTL Levels.
Standard 20 mA current loop or +/-10 mA bipolar current loop.
>2. RS232
At least RS-232C did not specify speeds above 9k6, so going to 20 mA current loop would be sufficient. Paul

Hi, Thanks. I forgot to add that I need a cheap working solution for mass production. Something with normal optocouplers. is it possible. Thanks, Rohan
