Thank you so much Edwin ! I really appreciate it. The node ID's I placed on the document are just examples. Of course they can be any number you like from 0-127 with CANopen, I do believe. Just as long as they are all unique. Used to be only 0-63 with DeviceNet, which is also a protocol based on CAN, as is CANopen. The main takeaway is that there should only be two terminator resistors, one on each end of the bus. Let me know if I can assist further. Thanks again. Kevin

Hello edwin. I have edited your diagram to show how to use multiple devices on the canbus. You can have at least 64 devices, perhaps more these days. Terminator resistors should only be at the very end of each side of the bus and each device has to have a unique node ID. Of course the baud rate should be the same on all of them as well. I also have the exact model Grayhill keypad and would be very interested if you could direct me where I might find the eds file? Thanks kevin202020
