Hello!
I have a question. I was thinking about a thing that would make my day easier. I have a engine that is electronically controlled, and which I can download the alarm history from. It's a normal 9 pins serial port, and since I don't have a serial port on my computer, I need to use a USB to serial port cable to connet to the engine.
The thing I was thinking about, was if I could connect to the engine remotely. Like forwarding the signal?
I've thought of two ways to do it.
- Use something like this (http://www.moderndevice.com/products/p4) to read the signal with an Arduino. Then I could use a ethernet shield to send the signals out on a network (there is internet connection where the engine is located). And the in the other end, I could use a ethernet shield to get the signals to the Arduino, and then use another P4 to convert the signal back. Then I could use my ordinary USB to serial cable and connect my computer to that.
Is this even possible? The baud is only 9600, so I guess it won't be too fast for a standard dsl internet connetion.
- The other thing I thought about is similiar at the start. With the P4, the Arduino and the ethernet shield. But at the other end it's just software. Then I would have to get a program made that will read the signals from the arduino that gets sent over the internet, and send it to my enginecontrol program. So the program I need to get made, simulates a com port for my enginecontrol program to connet to. On the enginecontrol program, I can only select COM 1 - 4.
I would like to hear your thoughts about this. Both the positive and the negative sides of the two options. This is just an idea I had, I haven't really thought it through that much.
