aldl

[Big Jeff]

can any one tell me how to make a aldl cable to conect to my serial on my laptop,
i have look on the internet but at the moment i have no money and i don't know when i will have some, so making it would be cheaper

i found my old laptop run win95 so it should be alright just to connect to the car

Na. You need a interface to adapt voltage. And a software to read data.

thanks,

i will post later how to make with pics when i get the parts

Its actually a pretty easy circuit and here is a link for the data sheet of the max232 op amp if you need it, before i buy my cable i thought of doing it but couldn't find the op amp here so i was going to order online, and the whole point was to make it from local parts here cheap so i just bought the usb version for peace of mind right now

keep us updated man and good luck

Max232 Datasheet

all i need for the cable is
1 x Diode code:1N4148
2 x Transistor code:2N3904
3 x Resisor 10k oms
1 x 9 way d socket (serial)
some wire
and software.

all these i can ge for about £5 to £10

you're using the transistors(which from what i know are low power amplifiers) instead of the operational amplifier in the diagram or your not following that diagram at all, because if there is another way i'd love to know it

[Big Jeff]

this one is the easier to make it,
but the Max323 is 95p on ebay if i decide to do it that way

[Big Jeff]

just thinking if any one can correct me please do to

if RxD receve data and Txd transmit its i could use a usb plug instead of a serial plug

e.g

power - A
RxD - B Data-
TxD - C Data+
ground - D

I'm not a software guru but I now the ALDL programs you can have for free were developed for RS232 serial connexion. I believe they won't work on USB ports.

Also take care if ordering the Maxim circuit. You need the MAX232! Not the MAX323.

i know which one i need , i just got it wrong on here, i will be a trail and error with the software

[Bob3825]

If someone knows a software that works with daewoo lanos or any kind of the new generation aldl please state it, i've tried a whole bunch of them but only got the EFILIVE V4 to work and its an evaluation so it only datalogs for 3 seconds i guess :S and doesn't read Trouble Codes and lots of other readings are messy, i guess they were meant for the old gm aldl or something because in WINALDL i only see the old types of ECUs, if someone has an aldl cable and tried a software with it please tell us so we know what works and what doesn't for future reference

[Big Jeff]

i have got a daewoo lanos file ,which i have just updated to keep it loging
PM me with your e-mail address and i will sent it to you

[Big Jeff]

i got one thing sorted





the laptop now has a chager avvire today

now it time to sort the cable
