PSP Slim and the remote/TV port...

digihoe · Post by **digihoe** » Tue Sep 18, 2007 2:13 am

Has anyone been able to figure out a schematic for this port yet? Is it still RS232? And can the PSP support RGB scart (read somewhere that the japanese cable maybe could be altered to support RGB)?

Best regards!

I can answer that without having one, no and no.
It never was RS232 until an RS232 converter circuit is used,
and theres not enough pins for the known functions + RGB
unless the component pins are switched internaly, but I doubt it,
as I've never seen any other hardware use the same outputs for both standards.

It takes extra hardware to convert component to RGB.
There was a project in Silicon Chip electronics magazine to do it.

So you never looked at the PS2, or the gamecube or.... :)

I had a PS2 for a week before any chips or homebrew.
It had RGB plus composite, but no component video that I knew of.

Can the PS2 can switch to Y, Cb/Pb, Cr/Pr on the same pins as RGB?

Yes, you can set the color output mode in the PS2 settings menu to either RGB or Component. The actual output pins are shared.

So there is hope for RGB? :)

What about the TTL 2.5V, is it still there?
I have not found money to buy one yet therefor I just ask here, hope it's OK.

Best regards!

It must be unless the remote is completely redone.
If whatever DSP was doing the TV tuner/ TV out could do component,
I don't see why the option wouldn't be in 3.60 firmware,
but here's hoping we can use an old Amiga monitor.

Okay, I used my VOM on my component cable and found this:

Code: Select all

Looking at the plug with the headphone plug tip pointed at you.

    1  2  3  4  5  6
    _  _  _  _  _  _  
o   _  _  _  _  _  _

    7  8  9 10 11 12

1 = ?
2 = ?
3 = VGnd
4 = Y
5 = VGnd
6 = Pr

7 = ?
8 = ?
9 = 42.5 kOhms to VGnd
10 = ?
11 = Pb
12 = VGnd

So I'd say the serial lines got moved, seeing as 3 is normally TxD, but is now VGnd. Not sure what the 42.5 kOhms to ground is. The component video lines are diode protected (open one way, ~600 kOhms the other).

The headphone plug is obviously the same as always - tip to left audio, first band to right audio, and second to audio ground. There doesn't seem to be an audio ground on the header.

Here is the wire colors for the standard psp slim remote...
I still cant figure out the new serial port pins :-(
any ideas?

Code: Select all

    1  2  3  4  5  6
    _  _  _  _  _  _ 
o   _  _  _  _  _  _

    7  8  9 10 11 12

1 = gray
2 = yellow
3 = ---
4 = green
5 = ---
6 = ---

7 = brown
8 = orange
9 = blue
10 = --
11 = --
12 = --

&#91;&#93;      white
&#91;&#93;     red

Hello.

Been looking at this subject for a few weeks desiding if I want a slim or not.

There are two other wires to add to the list... Both for S Video... A Y & C.

Starting to wonder if they went with a direct switch link or resistor ladder control when they dumped the iR link... See serial port would be use for both.

Have one but if no data in/out will just return the slim I just got and look for a phat...

If I can gather the time will try making an adapter and see if only buttons, resistor or what did they cook up... But 30 for the darn remote is a bit excessive even for Sony..

Tnks for those color codes and wires give me something to look at..

Well finally found a large Target store and a Circuit city that finally got in the 2000 version of the headphones...

YIPE 29.99 either place! Better be a microchip in there!

Oh well it covered under the R&D budget.. Unless the accountant looks close at it! O_O

ADDED: Frys has it for 25...

Need to verify...

From info in other forum here and the net will later pop in here.. Looks like this...

1 = gray.... PSP Serial Input
2 = yellow.. ~ +1.85V
3 = ---
4 = green.. ~1.85V
5 = ---
6 = ---

7 = brown ... Mike?
8 = orange.. PSP Serial Output.
9 = blue...... DATA GROUND?
10 = --
11 = --
12 = --

This matches with info on this site and here...

General serial..
http://nil.rpc1.org/psp/remote.html

The key is here...
http://mc.pp.se/psp/phones.xhtml

Data transmission I saw looks like from the link above but have not run a snoop on it yet. And strange. The color code matches...

May have the TX/RX backward... So take with a grain of salt for now...

ADDED: Ocured to me 1.85 voltage is basically 1 /2 of the 3.6 voltage of the battery... And the level need to power a Red LED.
