Can I link HU to my PC?

[studentone]

Sorry for my badly English.
I got a HU like this.I prepare use it as a audio amplifier of my PC.
I know there are several methods can do it:

Line in only:
These methods provide an audio input for peripheral devices through various connectors​

Aux Mod Basic- Line in only. Provides 3.5mm input through the Tape/MD jack. '06+ models the MEDIA button will access it the same way as the TAPE/MD button does on previous y/m's. This module is incompatible with at least '08.5 models as they do not have the TAPE/MD connector on the HU. Unsure about '08 models. ~$60 Installed Picture

Peripherals MAZASX Mazda CD Changer Interface/Auxiliary Input- Line in only. Provides one RCA input, and one 8-pin CD changer port compatible with Alpine, Audiovox, or Sanyo CD Changers. Includes an adapter to make the CD changer port a second RCA input. Plugs in via the Sirius/CD changer port on the back of the HU. Ideal for connecting multiple peripherals (external CD changer, DVD, MD, Mp3, etc.) at the same time. ~$99

P.I.E.- Line in only. Connects to the HU via the sirius/CD changer jack on the back, adapter connects module to your device. ~$75

Can I use the right rear connector connect to PC RS232?
---------------------------
| 1 2 3 4 5 6 7 8 |
| 9 10 11 12 13 14 15 16 |
---------------------------

6 Bus data (5v TTL, .3MHz data)
14 Bus ground

I link pin6 ,pin14 through a max323 conversion to RS232's pin2,pin3,and set baud rate to 4800 or 9600,PC can't receive anything.
If PC can receive data,is it possible that PC send some data to HU tell it CD Charger is exist?

Thanks,
studentone.

Your PC serial port uses a byte oriented protocol, one start bit, 8 data bits, and one stop bit. The protocol of your HU is completely different. To connecto to your PC, you will need a parallel I/O connection with fast sampling rate, and software to decode the protocol.

& I had no idea what either of you guys said. But, it seems like I should wish I did

There's a version of the grom module that can be integrated with WinAmp

That's awesome, exactly what the OP is looking for. How do you find out about this stuff?

Thanks,I'll try parallel I/O (printer port).

is very good. I think to try program when hardware(link HU to PC) is success.

I test hardware like below, I wish can get data at PC when HU power on.

Thanks for your help.
