Carefully lift up on the transport and gain access to the ribbon cable.

First remove the cable for the transport, then move on to the other two for the face.

There is a hidden screw under this piece of foam tape

Remove Five screws for this board

Try to pull straght up on this board when removing it due to the two large connectors underneath.

Take the previously removed board out and place it on your work bench. Fip it over to access the underside. You will be making your connections to the contacts of the KWE-610A receptacle. Enlarge this pic to see the pin assignment for your new Toslink transmitter.

Contact "4" on this board will need to be connnected to Pin 3 of the PLT133
Contact "2" on this board will need to be connnected to Pin 1 of the PLT133

It is not necessary, but I decided to completely remove the KWE-610A receptacle from the board. This allowed me to solder the new lead cables directly into the vias

You will notice a tin protection plate right behing this area. I had removed this plate when I was "exploring", but please don't do this... it's simply not necessary. This is where I decided to tap the VCC, but you will see later that there's a more pheasible location to tap VCC.

 

What are pins 1 & 3 used for?

Why did you need a capacitor? or is that a transmitter specific requirement?

Great DIY!

 

This is the "top" side of the board we are working on. Here you can see where I tapped the 5v VCC. This will connect to Pin 2 of the PLT133. Please enlarge the pic to see precisely where to tap into. I came up through the bottom of the board for my lead which is why you can only see the "tinned" cable, but it would be much easier to simply have your leads soldered to the top of this board

If you only purchased a sinle transmitter, now is the time to prepare the mounting. Unfortunately, you cannot just mount the new transmitter in place of the old recptacle. Unless that is, you want to drill new holes in the board and realign everything. I opted to use the dead opening to the far right of the back plate. It's uncanny how well a Toslink transmitter fits in this location!

You will want to remove some material from the chassis. Be sure to mask off the area as to not allow any debris to contaminate the deck's internals

Next up, you will want to drill out the mounting hole for the transmitter and find a nice "coarse thread" screw for secruting it.

Now you can make your connections to the PLT133. Be mindfull of your soldering time & temps here as the transmitter is fairly sensitive! Here is also where you will want to solder the 0.1uf cap across pins 1 & 2.

Here's the transmitter all mounted up and leads protected with heatshrink tubing.

 

Now just carefully reinstall all of the previously removed items and you're done!

Enjoy!!

 

I like where this is going. I didn't imagine this process being this labor intensive as it seems to be but it will surely be worth it when considering the cost of Alpine's optical cable.

I just picked up a broken w505 on eBay last night with a broken front panel and glass. I'll do the Toslink mod for sure when I have it apart to replace the broken parts.

I sure think so

Hope this will make it a little easier for you then

 

Wow this is awesome, I was just thinking the other day that someone should do a writeup on how to do this on a 505 and now here it is! Thanks a lot for the very informative writeup!

 

Good deal..

This is just my way of trying to contribute

 

Excellent tutorial !!

 

awesome post.

 

Ok guys now heres the big question, does anyone have the balls to perform this on say a w910?

 

I believe the W910 uses the same cable as the W505 (KWE-610) no??

Should be very similar

 

I love this stuff, Well done!

 

Thanks man!

 

Pretty sweet.... Been a long time since I've seen the guts of a HU... I miss it...

You can add TOSLINK to any CD player really...

Yes indeed you can. I remember reading that article several years ago and it was very informative. However, it's slightly out dated now that dvd transports are common place. Nothing in the W505 is simply labeled "D-OUT" If I didn't have access to a service manual for the 505 I probably wouldn't be able to do this. I probably spent more time tracing circuits and checking transmitter specs & availabitlity than I actually spent doing the mod.:blush:

 

This is great! Now if I can only figure out how to fix my dead W205.

 

I have managed to do a Ina W910R.

The 5 volts can be taken from te ic BA05s and take the 4th pin. (counting left is 1).

For the rest its the same as explained above, and the optic transmitter needs to have an other place.

 

Shawn, is there anything that you can't do? I was just discussing doing this same addition, but to an older Alpine single din pull out radio. The idea was to get more output flexibility to go with tasty OS goodness. This conversion adds somewhat more modern conveniences. It is sometimes sad that more manufacturers are not enabling us with better outputs, but why worry about that when someone with your mad skills is just down the road from me and can work his creative magic!
You 'da :bomb: man! Keep the goodies rolling!

 

I wish it was also this easy to make a ai-net bus on the new alpine units.

 

Hello, can u provide me the schematic, i want to mount an optical out on IVA W502, it looks the same like W505, but in my case is not working, i`m not shure if is wrong conection made by me or something else, i use a diferent optical connector. Thank you !

 

Did u turn on in the menu optic out? if not, turn this on!

It only works with the cd player.

 

I have turn it on, i have test it on my home powered by 12V pc source, IVA not conected to semething else, do i need i-net or something else to have signal to connector ? thank you !

 

No, do not think that Ai-net connector is neccesary but I'm not 100% sure.

What I do know for sure that RCA out is not working when optical out is selected.

Think you should isolate/test what is working correct. few steps to take:
1. Is their rca out or not (turn on and off the optical out in the menu)
2. Check polarity of the connector..
3. measure if the connector do get his right voltage to work. Look at the specs of your toslink wich voltage is needed.

 

Thank you for your help, i have recived wrong informartion about the pin connector, now it`s working good.

 

please delete.

 

I know it's an old thread, but I'd like to ask a question:

If I add the toslink output to my W505 and plug it into the PXA-701, will it send all the audio through the optical cable (ipod audio, mp3 on USB, etc) or only audio from CDs / DVDs?

Thanks.
