#150420 - ARCNET Responding to: ???'s previous message |
ARCNET is a well known and reliable (if somewhat dated) token passing network that can be implemented on RS485. Standard Microsystems makes controller chips that do all the heavy lifting. At one stage they made a 8051 variant with the ARCNET controller built in (or at least they advertised it), but I can't find a mention of it on the web site.
Look at http://www.smsc.com/main/catalog/arcnet.html You may also want to look into "CircLink" at the same URL. It appears (I have no experience of this product) to have some collision detection with a token passing network using RS485 as well. -Aubrey |

| all good and well; however ... | 01/01/70 00:00 | |
