How would you amplify a digital signal?
Sorry :-[ i'm just new with electronics.
but i though if you split a signal like digital it needs a 2.5V to get a logic "1" and if i split the siginal (as example) 100 times i dont get to the 2.5v For a logic "1" any more.
and as i do allot with "DMX protocol, RS485 (Lighting)" its also digital singal still if you like to Split the signal you need a Spliiter/Booster. otherwise you have the change your lights getting a life of there own.
Clearly you can connect the encoder to more than one thing; as you say, you just connect the lines in parallel
the "SICK" encoder has it own Gnd and 5+ , i dont need pullup resistors.
so when it happins it will get its own power supply and i will use a commen GND or as you sad a opto isolator.
EDIT: its the BFS60B with A_, A¯, B_, B¯, Sine+, Sine-, Cosine+, Cosine-, GND, 5V
and i use A_, B_, GND, 5V
Many thanks for making my life easyer :-D
