Arduino Serial Coms Over RS232, MAX3232 TTL Module and Rx/Tx

Other Hardware General Electronics
1

Probably a simple question. I have:

Arduino - MAX3232 - Wireless serial link sender - air wireless serial link receiver - MAX3232 - Arduino.

Currently debugging a few issues on this, i have it working using standard telemetry radios, 3DR type, however im now using a ethernet bridge which also has the abality to send RS232 data, and its currently not seeing anything.

Simple questions are.....

The arduino to MAX3232 is that RX to RX or Rx to TX?

The RS232 output from the MAX3232 module, is that again RX of the MAX to Tx of the wirless serial bridge? or again TX to TX.

I know with the telemtry radios its Rx to Tx etc, however some of the MAX3232 modules seem o be different nomenclature. I have a load of other variables that need to play ball, just didnt want to be chasing my tail on this one.

Thanks!

Anybody could guide me in the right direction?

Rx to Tx and vice versa.
