Hello,
my knowledges in electronics are very bad, so this is a newbie question. :roll:
I’d like to use the VM129 module. However, I just have a Measurement Computing CIO-DAS08-JR board. This board provides 8 TTL outputs.
What I understood is that the VM129 module should be driven from open-collector outputs.
Does someone know is there a possibility to adapt a 5V TTL output to an open-collector output? (maybe throught a ULN2803A circuit and a pull-up resistance connected to 5Vcc?)
Thanks for your answers.
