RS485 Speed and different routing possible?
Hello someone tested a higher speed setting for the (new) RS485 communication in MS2.0.?
I think that 9600baud is really slow. That being sayed i have to admit it works like a charm.
-So when someone can confirm that this works also with long(er) lines and higher speed i would like to know.
In my setup i use on one side (GW + RPI) a ADM2483 (isolator) so that i have a galvanic separation and can play safely with the sensors. these are often near the life (electric cabinet/enclosures) on the other side (sensors /field) i use the MAX485 or an SN75HVD12DR RS485.
Second question: is it possible to send a message from one sensors to another on the same bus? Without the need to use code in the GW? to route the recaiver?
Guess you have to do some tests... increasing the speed and see when it fails
Regarding routing, the messages will be routed exactly like in a radio network. Se you have to have a gateway node in the setup to send messages between nodes.
I knew you gonne hijack this thread
As you answered the first question (more or less)
i was looking for a good test rig
long distance transmission line
I yust have to re-read the specs off the ADM isolator i think
So there is no possibility to route from node to node pitty.
Tnx for the answer anyway i will try the higher speed setting (57K6 or so)
Btw good write up about the RS485 setup on the home page it will defenetly speed up things (as i spend a few hours wit wrong setup)
