I have a gps board which has a gps module. I need to take ttl outputs from the board. But, the problem is the board already has a max 232 ic and the o/p is given to the rs 232 com port.
SO, i brought a max 232 ic board and will connect the rs 232 pin of max 232 to rs 232 of gps board. I need to take rx and tx output from max 232 now to connect it to arduin uno. How do I identify the tx and rx pins on board.
I am posting pictures below.
