Yes it is. 120 Ohms. It is also specifically described as RS-485 cable. But I also noticed that Van Damme list their DMX cable as suitable for RS-485 and that that is available from eBay at fairly low cost, so ordered some in on a "just in case" basis. It is also a pretty purple colour. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Transform Data into Opportunity.
