How to upload a counter value to a website automatically 3. I round-robin poll my nodes on a 1. I have seen people implement servers which poll all devices and end up with just as good throughput Reply Start a New Thread. The data is sent in another 12 bytes, the entire frame is 16 bytes long. Of course, the ACK could be colliding as well, so it may have been received, but you just haven’t been told.

In reply to FrankL: Essentially the content of the packets can be any format protocol that fits your needs.
RS485 Bus with collision detect
Use double quotes around phrases, as follows: If it detects this condition, the detextion node has a higher-priority message, and this node should immediately drop out and retry its message later. You can never completely avoid collisions – all you can do is work out how to a detect them, and b recover from them.

Does the RX family have support to do this both jobs in hardware? However, here I need your help or anyone interested in pointing me out what and where I can improve. Paul Reply Start a New Thread.
On 22 Sep A node will not start transmission before the bus has been idle for a time determined by the priority. This could work quite reliable.

I detectin develped a RS state machine for this purpose, the system works Ok, but I need to know if there are any potential bugs in the system concept. The routine Wait for Bus comment says: Email Required, but never shown.
RS CSMA/CD protocol
In my case I “invented” a protocol that contained fields for all the data I needed for every node so they could take what they needed and ignore the rest. However, as was stated earlier, it will not detect a collision that occurs during a transmission. Sun Mar 04, 8: Your subscription request is being processed. What path should I follow?
