I am posting pictures below of the gps, gsm and max 232 modules.

The problem is that the gps reliever has max 232 IC on the board itself, but the output given is in the form of rs 232 port. So, I bought a max 232 board. So, I think I should connect the two using male-male cable. Pls see the pictures and suggest

Also, the gsm module has 3 ttl pins along with serial rs 232 port. The confusion here is which of these is rx and which is TX (which I would connect to 2 arduinos)

So,here is what I plan to do. I will connect tx n rx ports of one arduino to gps module and get the data from it. I will use one pin of 1st arduino to activate another pin of 2nd arduino , to which I will connect a gsm module (rx and tx) , which will send a message to a mobile phone containing the data.

I will be using 2 arduino uno boards (1 for gsm and 1 for gps)

Please correct me if I am wong.

I will connect this max 232 board rs 232 pin to rs 232 pin of gsm module, and take rx and tx output from out (printed on max board) to arduino. But I am again confused which is rx and which is tx for max 232 board?
