I have a special request, if somebody can help me.
I buy a VM8090 8-channel USB relay board and I make the test of it right now. Till now everything is OK.
My question is:
I need to command 3pcs VM8090 boards with 8 relay each one ( 24pcs relay ). How can I set the address to each board ( as dip switch, for example ) to give ON/OFF commands to each relay?
The same thing if I have to command 20pcs K8090 boards ( for another project ).
