Hello,
Thank you for our time.
Currently I ahave already done:
- removed R11 and R16;
- replaced r30 with a 120ohm one;
- removed r20 and connected pin RS of the transceiver directly to ground, because with this resistor the transceiver was working in slope control mode and not in Hi-speed...
Hello,
I managed to contact the previous electronic designer, he told me that he uses this design with sucess in a network of 25 ndes, but at a speed of 25Kbps.
Probably it can all be solved with a component values change.
Anyway I am on the process of removing all the protection circuit to...
Hello,
The project is about a CAN sensor network, so the cable length between nodes may vary, from a few meters to some tens of meters.
The tipical environment were we will use the system is in data centers, however it can be applied to factories or other harsh environments, and it was because...
Hello,
Thanks for your reply, I started with 250kbps, works for three nodes, and lowered it to 125kbps, allowing me to have 5 nodes working without problems. Since se intended to have 60 nodes, this is a major problem for us
Regarding the nodes wiring, there is a utp cable connecting each two...
Hello,
I have a project were several boards connect to each other using a CAN bus, however, I am having problems with the can physical layer.
If I add more than three nodes, they stop comunicating.
I discovered that if I add terminator resistors in each node, lowering this way bus impedance...
