Patrick Posted September 12, 2018 Report Share Posted September 12, 2018 The only built in serial is the mini USB for programming Also in the Samba 7 technical spec : Notes: 6. The user may order and install one or both of the following modules: - A serial RS232/RS485 isolated/non-isolated interface module, or an Ethernet Interface module in port 2. - A CANbus module modules documentation is available on the Unitronics website. So I have Ethernet modules and CANbus modules available for the Sambas, and the Vision is delivered with it built in ! Quote Link to comment Share on other sites More sharing options...
Patrick Posted September 12, 2018 Report Share Posted September 12, 2018 I have just learned that I can do a Broadcast in UniCAN to all controllers on the network, brilliant! The only downside is I am going to have to spend a load of time learning how UniCAN works.................. Quote Link to comment Share on other sites More sharing options...

Gabriel Franco Posted September 17, 2018 Report Share Posted September 17, 2018 You may use Modbus TCP using UDP instead of TCP, then you have not to connect/disconnect from the slave every time you want to communicate with the next one. Only add a small timer between slaves. I´ve used a timer as short as 10 ms with sucess. Quote Link to comment Share on other sites More sharing options...
