PS1CardLink - help with cable needed

[MAKOS2148]

So hi all , as the topic name say, i want to use PS1CardLink from Shendo, and i got the cable but i need the anser for 2 questions

1. Can i just use this (http://www.psxdev.net/forum/viewtopic.php?f=47&t=66) scheme to connect properly the TTL-USB Converter (CH340G)?

2.Can i connect the cable without soldering it? I mean using the insulating tape and/or this connectors http://imgur.com/Z27KB0M

Thx for replies and help

Hi.

Yes, you can use that scheme. The lines you need are TX, RX and GND.
Pins on TTL-USB adapter are for the end point side, which means you need to connect TX to TX and RX to RX.

Check out Type 79's cable.

Take a note that PS1 uses 3.3 V logic while TTL adapters usually have 5 V logic.
So you should put resistor on TX line or use a logic converter. Or if your adapter has a 3.3 V switch use it.

Ok thx for help

So hi there, i have a another problem. I done a cable which alowe me to copy saves from PC to Memory card and vice versa. Or it should. Because today i tried to copy saves, unfortanley the MemcardRex dont detect the PS1CardLink "PS1 CardLink was not detected at "COM1" port" . I use the ch340 usb-ttl converter. Can someone point me what is going wrong?

[Shendo]

COM1 is probably the real serial port on your PC.
Go to Options->Preferences in MemcardRex and select a different port.

If you can't find any make sure you have drivers installed.

[MAKOS2148]

I changed the port eailer and still the same (and my motherboard is too new to have any serial port) , and i installed the drivers (i dont even try without it). Oh and i forgot to mention, i use Windows 7 64bit (with test mode enabled, if it change something)

[Shendo]

Some new motherboards can come with a COM port, but only with a header and not a DB-9 connector.

But anyway, short TX and RX on your adapter and see if you get echo from Putty.
Then burn PSY-Q echo sample for PS1 and try then if you have an echo.
If not then check your wiring, TX, RX and GND lines are required.

If that's working fine PS1CardLink should work properly.

[MAKOS2148]

I get today a cd so i can burn the test program (i use the PSXSERIAL, should work, right?) and nothing just waiting for PSX the CH340G transter led (as i look its like CH340, it just have the voltage changer from 5V to 3V and vice versa nothing more) just blink. But there is a strange thing, when i turn off the console while the program on pc search the PSXSERIAL on COM PORT then the program say it find it, send the program (and the transfter led lights) and looks like sucsessfuly send the programs but it doesnt (when i saw it i thought: WTF!?). And i still cannot use nice piece of code

[Shendo]

As I said, try with Putty first to see if your adapter is actually working properly. Wire TX and RX together.

[MAKOS2148]

Sorry for delay in reply but im little busy for the week and now i have more free time so i can test, and:

- If i boot to the BIOS (w/o cd) i got nothing
- If i boot the cd with game i get some strage strings (http://imgur.com/wZGIWME) and it keep going unless i connect gamepad (no matter in which port), after this is stop printing the strings, when i disconnect the pad , the string is continue to print (tested with Quake II NTSC and Colin mcrae rally 2 PAL)

What do you mean exactly with connecting 2 lines together?

[MAKOS2148]

Can someone help me? I'm really want to copy the saves from the console to pc and vice versa

@ MAKOS2148

Can you post some pictures of your hardware setup?

[MAKOS2148]

What exaclty want? PC setup, PSX model etc. , both or something other?

[Greg]

CH340 and PSX link cable.

[MAKOS2148]

I got it , maybe the quality isn't very good but I think it acceptable (for now I cannot make it better)

PS. Normally i use the insulting tape in cable connection but I remove it to detailed view of a cable

Connect CTS and DTR together on your adapter.

If it still doesn't work disconnect TX(D) and RX(D) from cable and connect them together.
Then use Putty to see if your adapter actually works.

If it works then wire RX and TX back to your serial PS1 cable.
If not get another adapter, ideally without exposed DTR and CTS lines.

[Greg]

As Shendo says, connect RX and TX together, you can use the cable that came with the CH340 for that.

then run putty with this configuration;
connection type: serial
speeed: 115200
serial line: COM port of your CH340



if everything is ok, anything you'll type on the keyboard will appear on the screen.



now we can go to step 2.

[MAKOS2148]

Sry if it will be stupid question but I'm newbie with electronics. What do you mean with connecting 2 cable together

[Shendo]

Wire it like this and follow Greg's advice.

[MAKOS2148]

So if i connect CTS - DTR, RXD - TXD on adapter it working, it write the keys what i enter, but when i reconect it to the Serial cable, nothing like earlier
