Hello,
We update an old industrial network based on RS485 at 1 Mbit/s, we used ISO1430 wich work perfectly to replace old components (driver+isolation transformer). We use simple pairs cable (150 characteristics) with 150 ohms termination at each end, 1 equipment with ISO1430 at each end, 1 sypbus to check frames at each end too.
Our tests works well up to 1500 meters with 1 Mbit/s (without repeaters) wich is correct, almost same than old components.
My question : we supply ISO1430 with 5V, maybe you have the answer, i looked for but not find precise answer, if we supply with 3V3, will we have the same distance, or can we estimate the loss (or ratio) ?
Regards,
Bruno.
