Hi,
I have a video camera with a cabled remote which controls the camera iris, colors etc...
I do not know the protocol, I want to learn the command sent by the remote into the camera.
Here is what i did so far:

First try:
1. bought 232Analyzer software
2. cut the remote cable and discover (through manual) the correct data wires (TX+, TX-, RX+, RX-)
3. connected the TX+ and TX- into my serial port [pins 2+ and 5-]
4. set the port settings (which i do not know them) to many different options
5. turned everything on and start operating the remote.

The results in HEX was only a bunch of FF's, no matter which button i clicked the result was FF.


Second try:

1. bought 422 to 232 adapter
2. bought 485 to 232 adapter
3. tried the test with each adapter

same results, only FF

:(
