I am working on a project to read data from a GPS and display it using RS232 serial connections. As such, we ordered an RS232 shield.
My first question is if the shield does indeed take care of all the RS232 to TTL conversions.
We ran into an issue where the GPS connector and the shield connector were both female so we attempted to use wires to connect the two. I am worried that we did not properly adhere to RS232 connections and my have damaged the shield. However, the code we used did manage to get something although the data looked like gibberish.
Believing that our RS232 connection was faulty, we bought a female to female adapter. However, upon connecting to the GPS, a very quiet but distinct beeping/buzzing sound was heard from the shield.
Earlier today, I had used code to test the RS232 shield with hyper terminal. I could type in a letter and then the board would print out the value of the letter in different formats. This worked fine. Unfortunately, after the aforementioned beeping/buzzing sound, we tried to test the shield again with the code. We were unable to connect to the RS232 Com port in hyper terminal. Also, I'm not sure if the Rx light was lit earlier but currently, the Tx light is the only one lighting up.
I believe we have damaged our shield but before we order another one, I was wondering if anyone can help us.
Thanks for your time.
