Logger cable troubles...
« on: December 14, 2012, 11:16:31 PM »
Ok so ive built my own logger cable, but im not having any luck...

ive used the following schematic that was posted here in the following thread

http://forums.ds-map.net/logging/jackal-logging-diy-set-up-for-1g-dsm/


The only difference is that ive swapped pins 2 and 3 on the 9 pin db9 female connector so i can connect to a pc without the null modem adaptor easily.

Diode is the right way i believe and i installed the resistor near the aldl plug as to keep it from being cramped in the db9 plastic hood.

Any ideas?  I get no connection with jackal and nothing with TMO.... running a belkin usb to serial converter that has all drivers installed properly and works with my LC1 wideband serial cable... it is NOT ftdi based however. Shouldnt the usb to serial still work for TMO atleast?

Here are a few pics of the cable.  blue wire is the ground and green is data.
2nd pic, the wire going from pin 10 to 12 is actually soldered to pin 12 but looks a little odd...

This may just be me.. cause its 2:55am... but it looks like you got the wrong 'side'

Isn't the pin count, from the rear... top right #1, next 2, etc etc  ?



If not, that diode is probably reversed then since you want the diode protecting the TX... not the RX.

And for the record, the resistor is not needed.

Nah, the back and fron of the connector are numbered. its right as far as pins go, diode looks to be protecting the tx (pin 3).. but i guess ill swap it around and try it the other way and see what happens...

Are you using a female ?

Yep, printed on front of female connector and back near pins.

Diode check the ground loop to verify its putting the ecu in diag mode.

Ok so i bit the bullet and bought a logger cable from dsmcables.com with the aldl connector. I have a male db9 connector on the cable and my usb to serial connector (belkin f5u409 model) has a male connector as well.
Im assuming this cable is setup for palm logger style, so i bought 2 female db9 connectors and ran some wire between them (swap pins 2 and 3 and 5 straight through to ground) but ive got no connection to tmo still...

 LC1 is working fine with the usb 2 serial adaptor however...  My guess is that since its NOT ftdi based that this is causing the problems since the ecu communicates at an odd baud rate.  I guess ill have to look around for an FTDI based usb to serial converter that is null modem and has a female end.

im assuming this would do it?

Seeing as how my logger cable has a male connector.

Man I thought you were just using a rs232 setup, had you mentioned you had a usb converter it would be painfully obvious the device does not support the non-standard baud rate of 1953.

Any FTDI 232 device will work just fine, that one seems weird cause it says 'into null modem' so I'm not sure what that means.
