Hi
The jumpers has been replaced by the dip-switches, one group of 6 deserve 2 channels. As for the jumpers are 3 settings for one channel.
If you look at the card with the raspberry 40 pin connector up, the first switch on the top is for 0-10V, second for 1k thermistor and third for 10k thermistor. The order is repeat for each channel. (as for the jumpers, only one of thee switch mut be on). Usually the cards come from the factory with 0-10V input settings because that way was tested.
The "485TERM" is used to connect a terminator on the RS485 lines. The RS485 network needs on terminator on each ends.

what about getting the 1-wire interface on the Bas to work. which node in NOde red, as there is none available and the IND node will not work on it
Hi,
There is no node for the 1-wire and you can not use the one from industrial but you can use the exec node running the "megabas" command for it.

So no node to get temps from 1 wire interface on the bas v4? Then why advertise that you can. I'm confused now. Lol. I do not see exec node either
Here is an usage example:

Thank you! will give it a go tomorrow, thanks again

perfect! thanks Alex

will this allow for 2 sensors
?
?
yes, with proper modifications.

What are those modifications, I need to read 4 ds1820 sensors from 1 wire interface. Thank you again in advance!
The easy way is to add a new exec node for each channel and connect the input of one exec node to the output of the previous so the new command will be executed after the previous one is finished.

perfect. heres what i have. how do i go about extracting the 2nd temp so i have 2 values simutaneously?

i figured it out, thanks again!
Sorry for being slow, I am switching between projects and I had no Building Card installed to test with.
I am glad you figured it out.
