New LM2 without serial port?

[Protec]

Just received my LM2 and it was my understanding that it had a serial port on the device so that I could use the serial cable that came with my flash Scan....

Well, no luck.. no serial port..

I prefer TaQ but they are back ordered...


Does anyone know if the "LM2 to USB" cable can be used for the EFILive Scan tool if I don't run their software?


Any help would be appreciated.

Hi John,

No, it has to be a serial cable.

Did Innovate remove the serial port...?

[Protec]

Yes they did. I'll be trying a combination of several things to get their output a serial to a null modem to meet up with your serial cable to the V2.

If that does not work or produces less than accurate data I guess I'll need to use their serial I/o and wire it to the v2 as a last resort.

Does Innovate write the serial data thru their USB port (so you can use a USB-serial converter)...?


Can you post the new LM-2 user manual pdf here.

[Protec]

Here is the short version user manual at 51 pages.

They have a 4-pin MTS Serial IN -

Not sure if this is what was supplied on the old units or not. I assume I could use their cable and wire in a male serial end to connect to the V2...

Hope this helps.

On page 4 of the user manual, it shows MTS Serial OUT... does your LM-2 not have this...?

[Protec]

Joecar,

Yes. I was expecting a "serial" port in my limited knowledge of old school serial ports on computers.. Do I just need to wire one together that mates with their 4 pin MTS?

This would then connect to the efiL cable..

I apologize in advance if these are very basic questions. I appreciate everyone's time with me.

It should come with an MTS to 3.5mm cable... cut that cable and crimp the RJ12 connector and you have a perfect cable for your system. Don't know if the TAQs are still being made.

[Protec]

Highlander,

Thanks.. The setup I just received did not contain the MTS to 3.5 but I can get one and modify the cable. Appreciate the advice..

Ok Guys -

I connected the MTS to the EFILive Serial Cable by cutting the ends off and soldering the 3 wires together on each.

I've tried adding the PIDS in V8 to see if the BBx would see the LM2 but it states no sensor found. I loaded the BBx to the Wideband Settings in Scan and tune and still nothing.

What am I missing here.. I'm at a loss....


Thanks,

John

[joecar]

Did you cross the Rx and Tx signals...?


On your V2 you can navigate down to the wideband display to see if it is working.

[Protec]

joecar,

Can you expand on the signals? Im not following - Apologies.

I went to the "Show Wide band" and when I select that I says not found. I hit Ok to toggle through 1 & 2 and still nothing. This is on the V2 BBx


Sorry~

[joecar]

To talk to your PC, the Rx and Tx wires go straight (not crossed).

To talk to V2, the Rx and Tx wires need to cross (i.e. null modem cable).



See posts # 10, 15, 19 here: serial-port-cable-that-goes-to-v2 (http://forum.efilive.com/showthread.php?9340-serial-port-cable-that-goes-to-v2)

Thats probably my issue.


Here is what I did.

I took the MTS to 3.5MM cable from Innovate and cut the 3.5mm off - This left me with a Red, White and Black wire.

I took the Serial cable to RS232 (EFILive Cable) and cut the Serial end off leaving me a Red, White and Black wire.

I thought by connecting these two cables together I would have in essence a direct serial cable from the LM-2 to the Flash Scan V2.

I don't know that the red/white/black on each cable correspond to each other...

does the LM-2 user manual indicate what each of those 3 wires is...?

[joecar]

I just looked at TAQuickness's instructions for the LM-2 cable, they say to connect SERIAL OUT to FlashScan V2...

i.e. SERIAL IN will not work.

I think that you should explain to Innovate that previously the SERIAL OUT was used to communicate with the EFILive FlashScan V2, and that you need an LM-2 that has the SERIAL OUT port.

[Protec]

The LM-2 has a MTS 4 pin "In" and a 4 pin "out" on the side of the case...

As per the manual :

Serial Out
Pin Use
1 RX
2 TX
3 GND
4 GND


Can this still work?? I'm not sure of the corresponding color wires as I don't have the MTS wire with me, but can you tell me what the colors of the EFILive Cable correspond to with regard to TX, RX and Ground?





Any help is appreciated,

[joecar]

So it has a port labelled MTS SERIAL OUT...?

If so, then that is the port you want to use;


you want a "null modem" cable (meaning Rx and Tx are crossed, see post #14 above, those links show the EFILive cable wire colors).

[Protec]

Joecar - Thanks for all your help. Here is what is needed and how to do this without a null modem adapter..

You will need a Innovate #3812 Serial Patch cable that has a 2.5mm jack on the other end and the Flash Scan V2 Serial Cable.

The #3812 can be had on Amazon for $12.00 if you don't have one in your LM-2 kit



Take the #3812 and cut the 2.5mm Jack off the end.
Take the V2 Serial Cable and cut the 9 pin female off of that cable.

You will have a black, red and white wires in both cables after you prep them.

Solder Black to Black
Solder White to Red on the respective cables.

This as you stated provides you with a Null Modem Cable Tx and RX crossed in a streamlined cable.


Thanks for everyone's help.


Best,

John~

Cool, thanks for posting back :cheers:
