CW with Yaesu SCU-LAN 10 remote control system is possible

Running an Arduino (in the black box) connected to a local PC via USB. Signal goes via LAN or internet to a second Arduino (Uno with Ethernet shield) and via an optocoupler to the Yaesu FTdx10.
There is almost no latency and first remote QSO's are already made.
Based on iw7dmh sketch and with great help of pe1glx.
The local keyer has 4 memories also and you can connect a straight key or an iambic paddle.
Software is in test phase at this moment, so no publication yet.
