how about get hyperterminal going
poke the rx pin with the 5v pin
if it's working you should get garbage in hyperterminal.
or type stuff in hyperterminal, tx light should light up on the board.
with these modern FTDI chipsets, they shouldnt be that driver-sensitive. the latest driver should be fine..
Ok so using hyperterminal only the tx light lights up when i type whatever on the keyboard. I have the tx and rx hooked together. When i touch the wire from the tx/rx to 5v no lights light up.
i dont care about the light, no garbage shows up in hyperterminal when you poke the rx/tx with the 5v? im calling defective board here or something.
I will recheck with my volt meter but i think the tx/rx output 5 volts. Idk if that matters any im just thinking if it outputs 5v and you touch it to its 5v supply would anything happen. Also i noticed that if i touch the tx/rx to ground the device dissapears from the pc and i have to plug it into another usb port in order for it to be recognized. Thanks for your help so far everyone.
I am excited to start data logging. Is their a definitive way to test for a bad board.
if you're able to consistently send and receive the same data, i would say it is working as expected.
if you don't see the same data in the receive side as what you're sending, that is a problem.

How would i test to see if the recieve side is seeing what is transmitting? My ft232rl looks like the same one you use. I noticed that the numbers on my ftdi chip differ from the numbers on the ftdi chip on the ebay link of the adapter you use.
