Hello,
I have an electronic device which is powered by ethernet. There is no power switch on this device so only way to control is to pull the Ethernet cable. It is used to program electronic keys, even though I have access to the source of this device, I am treating it as a black box (or off the shelf component)
This device can only be set via connecting a USB stick to it. When you connect the USB the device automatically picks up the correct file from the root of the disk. Then when you take out the disk it changes the new settings.
There are six LED indicators and a buzzer on the device as well (which if I can remove the housing for the device I can also have some access to, some tinkering with the wiring may be required)
Now I want to create a simple system with which I could automate the process of restarting this device and putting new files on this device with use of arduino and some electronics.
What I need is a way to connect a USB device to this system (so it would be connected to a PC and then it can be ejected and switched to the system in question) as well as to control the Ethernet power connection some how.
I am not sure what sort of electronics is required for this. The information to work this out should already be out there (how USB works, voltages etc, how PoE works. I can red behind the hardware PCB and it says Power 7-24V AC/DC. Not sure what that even means).
Thanks for reading.
