Title: Emulator connecting to HU Post by: kamil f. on 05 Jan 2004, 00:03 hi,
I want to built an HDD MP3 player which can be controlles by Pioneer radio. I know that its already made, see Yamp3usb and vitats adapter, but I want use an USB2.0 chip for faster fileload and STA013/CS4334 for better soundquality. but I have some questions about IP bus ( adapter ). what happens when I connect the adapter while HU is running for example at tuneroperation? will the adapter successful recognized? so I can change to CD changeroperation whitout problems? what happens when I disconnect the adapter while HU is running ? will the HU successful recognize that there is no more cd changer? oder could it be that he HU software crashs so I have to reset or turn OFF the HU? what happens when a MD changer is also connected together with the adapter? the background for these questions is that i have to decide the circuit design. 1. the controllpart is at the main mp3 player, so it would be disconnected while I have it at home for downloading files 2. the controllpart ist separated from the main player like vitalis, so that the HU views altimes a changer ( an empty if mainpart is disconnected ) it will be take a few days until ich become a running adapter because i have to order some parts for the adapter. then I can start tests an maybe I will answer my questions by my self if nobody has tested it befor. I measuring up to now that the ASENBUS, BUSP1 and BUSM1 is enable as long as the ACC ( ignition ON ) in enable even if HU is turned OFF. see you :D Title: Emulator connecting to HU Post by: Anonymous on 08 Jan 2004, 17:36 hi
there is always a communication between HU and CDC even if the HU ist on standby (send status, acknowledge....) so the HU will notice that there is no changer after a few sconds (i don't know the exact time) i had no problem to connect the emulator when the HU was already powered on (source tuner) the only thing that happend was that the HU went on standby when i switchen the source to CDC after that i switched it on again and everything worked fine. if you disconnect it when HU is switched on CDC it will take a few seconds and the HU will go on standby i wouldn't recommend to connect or disconnect the emulator while the HU is running but it works two best regeards mike Title: Emulator connecting to HU Post by: Vitat on 12 Jan 2004, 21:56 kamil f.,
Quote what happens when a MD changer is also connected together with the adapter? It's not working... You must have a special adapter to connecting more devices on bus.Quote the controllpart is at the main mp3 player, so it would be disconnected while I have it at home for downloading files If you turn off the ACC or remove panel from HU, the ASENBUS signal from HU turn off too, and IP-Bus adapter with MP3 player turn off TOO!Title: Emulator connecting to HU Post by: mike on 14 Jan 2004, 10:51 hi vitat

kamil f. have a MD-changer with IP-Bus output and input! Hi says that MD-Changer and emulator working together!!! I'm not understand how, but it very interest. :p Title: Emulator connecting to HU Post by: Anonymous on 22 Jan 2004, 02:20 hi,
I tested ! the MD player runs properly together with the emulator. both player are connected in series. emulator => input of MDPlayer, output to =>HU all devices from pioneer are connected in series, DAB tuner, CD changer, aux in adapter,etc on PCB of MD changer i saw the bus+, bus- and ASNbus are connected parallel at IN and OUT put.
