Help making an emanage cable?

[airman86]

Hey all, after pouring over the internet for several hours, i have found two guides on how this is done. I got a deal on an emanage blue with ignition and fuel harnesses, a greddy type-s bov and a 28x6x3 FMIC for $250 which i couldn't pass up. The only downside is that the emanage didn't come with the cable. These are the two guides to make one I have found:

http://www.mazdas247.com/forum...59030a ... um...98845

The first one is good, shows the importance of finding the TX and RX, but doesn't explain how to use hyperterminal and exactly where each cable goes on the other end of the USB. The second one shows pictures and how the colors match up, but no cable is the same and I doubt I can find the exact same dku-5 cable with the exact same colors that I found in the guide.

Can anyone shed some light on this? I keep finding references to mohdparts.com which seemed to have plenty of info. I have been all over the yahoo groups, i have searched on nicoclub, google, and just about everywhere else. I have had luck finding a write-up on yahoo groups, however all of the links and pictures are broken. There is a writeup in the Files section of the emanage yahoo group. The link to the file is there, but an error gets returned that says "file not accessible", which I don't understand because these files are hosted on yahoo's servers. It's not like they're hosted somewhere else that could be unreliable.

Any help is much appreciated, thanks.

So your trying to make the USB cable for it? I've seen it done before but i don't remember where, I think your best bet would be to get in touch with Greddy and just order one. My friend just sold his emanage blue with everything needed for it.

I don't feel the need to spend $100+ on a cable that I know can be made for less than $20. I have the skill and the know-how on how to solder/splice/do whatever, I just can't find a guide without the link being broken or info being left out.

I know a lot of people who know how to do this don't want to share simply because they can profit off the knowledge as well - order a bunch of cables, splice them up and sell them for double or more profit, and people will buy them.

Well i wouldn't exactly cheap out on an emanage. Don't they have a specific plug on them anyways? I don't really remember so excuse me if I'm wrong.

yeah, they do. the "usb" plug on the unit itself is actually serial. i'm going to pick up a plain serial cable tomorrow and see what i can wire up. all that goes into it are 3 wires - the TX, the RX and the ground. I just have to figure it out myself, it will just be a little tedious. worth the trouble i think.



this should give me a good start - a little bit of playing and cross referencing to a few of the guides should get this cable done. looking at it that way, i think i can figure this out. the laptop i'll be tuning on has serial, so there's no point for me to worry about usb>usb.

alright. i've got the cable wired up. i know the cable is working because of a successful loopback test with hyperterminal (touch the tx and rx wires together). however, something that has bothered me since i have gotten this unit is the "interaction" light stays on, regardless of whether or not it's hooked up to a PC. i haven't found a -clear- answer if this is normal or not anywhere online.

anyways, i can make the interaction light blink when it's hooked to the computer. all that has to be done is connect to it using hyperterminal, and start mashing keys. SUCCESS! blinky lights. occasionally i'll get some strange acscii characters back from the emanage showing that it's supposedly working.

however, support tool will not pick it up. i've tried every type of setting available (even tried changing com ports even though I know it's com1) with no dice.

the emanage is outside of the car, with only 12v and ground run to it. perhaps it needs to be in the car first before it will talk to a emanage?

much help appreciated.

I put a lot of info in this thread zerothread?id=394118 and bought the OBD1 to serial here http://www.e-mance.com and the serial to USB adapter on ebay.I can take a pic of the wiring later.
