You need a ttl converter, make one or buy a rs232-ttl cable.

It might work, but why dont you buy the TX comms cable and support the comunity and the research of new products?

because i already have done that with nandx,coolrunners and x360 usb pro, theres no reason to pay 20 euros (with post at my country) for a cable of 1 euro

nevermind thanks for the help

Okay, but you got the answer, so just get what you need or build one.

I think the problem is that you need a ttl converter. The update cable is usb to rs232 ttl, or at least i thinkt it is, i updated my nand-x using a rs232 ttl cable from ftdi.
Google it, there are some easy solutions on DIY versions.
I'd love for this to be confirmed by TX. Isn't RS232 and ttl different protocols? I always thought it was RS232. And why hasn't there been a disclaimer or closer of this thread if standard RS232 won't work?

Not being a smart ass I'm just curious about the protocol

All i know is that if the update cable works for com-monitoring, and my rs232-ttl cable from ftdi works exactly like the update cable, it probably needs the rs232 converted to ttl (i think its inverted signals, and 5v signal). Build a converter and try, i would if i wasnt at work.

Theres only one way to verify it :) as far as i remember, its also the same way we read the key on the older lite-ons from the beginnig.

I don't think I want to go through the trouble to find out lol. Xecuter or Steff would be able to answer the question if they choose to reply. Both of them has posted comments in this thread and they would know since they are the developers of the hardware and the software that is recommended to use.

I've only attempted monitor comms on the console I talked about above. I always scan for the IP as it easier. I may however try on a different console with standard 232 and see what happens.

You can make it with 2 transistors and a few resistors as well, its all integrated in the sugested max circuit.

Dont bother thanking me for posting your solution :)

Tried my ftdi 232r-ttl-3v3 yesterday just to make sure it realy works for this as i stated, and it does. Will not post what color of the cables goes where but it works.
