Tying SSR8’s together should work fine for me, since I’ve wired the enables to the second board’s SSR8. Changing to dout.07 is easy enough.
I don’t have the boards here to visually verify, but I did set switch 10 before installing. I also wired up the boards with the ribbon cable configured as you specified. Both boards show up using the diagnostics program’s bus display, with the second (older) board identifying as version 3, and the first board as version 5. On the HAL Configuration window, all pins from both boards enumerate as expected. > On Feb 14, 2021, at 10:40 PM, Jon Elson <el...@pico-systems.com> wrote: > > On 02/14/2021 09:03 PM, Matthew Herd wrote: >> Thank you Jon.
