Message from CristianC
Hi all,
I had sent a PM to CristianC and he replied by email but allowed me to post his reply here. My main question was about how he got the hex dumps (which schema, which conditions, etc). Here's his message :

Hello
I have found the test board that I have used to conect HU to PC. This is the schematic (attached) but I think that your schematic is better.
Translation of my original message:
1. Start HU => HyperTerminal recieve: 3D 01 FE FD 3D 01 FE FD 3D 01 FE FD (hex code) => 3 connect attempts
2. If connect DATA-IN with DATA - OUT => HyperTerminal recieve: 3D 01 01 93 AE C5 => connected but HU waiting something to activate AUX input
I think that all emulation device can be made with a single chip. For example dsPIC30F5011 from Microchip.
This DSP has:
- high speed ADC convertor
- SP-DIF interface can be emulated in software (I think)
- UART port (can be configured as 9600 8-E-1)
