I've posted several topics on here but i don't know how to find the previous ones.
I am using a TTL to 485 converter and i'm experiencing some problems. My converter works WITHOUT enabling the transmit pin. also, if i put a scope on the enable pin when only giving it a power supply, there is a voltage of 5V on this pin, so appearantly the board makes the pins HIGH by just supplying power.
this way i can't get it in receive mode and thus it is not working. has any of you experienced this before? i think i just need to get a new converter.
maybe you have a different idea on this.
