The LM-1 analog output cable is a 3.5mm stereo connector:
Analog Output 1( Red)
Analog Output 2(White)
Ground (Shield)
I have currently have one (the other three I bought didn't get shipped) pigtail connector, and also the connector on the side of the EIO. These two housings don't mate. Neither the loose wires from the pigtail nor the analog output cable seat into the EIO connector.
Also, the dox refer to Pins 1-8, but there are not any markings to indicate the sequence on the EIO box. ???

The pigtail is keyed and will only go on one way.
Don't go by the pin numbers. Use the wire colors to determine which function you are using.
There is a white protection plug on the EIO interface. Remove that and you can hook up the pigtail. Put the protection plug back on when you remove the pigtail.
Depending on which analog output the AFR comes out of the LM1 on, hook either the red or white wire to any of the 4 A/D inputs.
That will be one of the white, purple, blue, green pigtail wires.
Hook the shield wire to the black wire on the pigtail.
Use crimp connectors, or solder and electrical tape for your connections.
Tape off any unused wires from the pigtail.

Looks like I fingered it outI didn't find the part in the documentation which says you need to remove the connector which is already in the side of the EIO. I thought you had to connect external wiring to it as-is. So I inserted a small blade to release the latches on the connector w/o wires and swapped in the pigtail.
LM-1 analog Red <-> EIO White
LM-1 analog Shield <-> EIO Black
Guess I'm off to Radio shack for protected crimpers. I'm psyched!! Thanks Ken, Keith & Chris!!
Yeah, I think I will have to include a mention of the protection plug in the help section.
On the protection plug and pigtail, it is a "pressure" fit Molex connector.
Just pull on the plug or pigtail to remove it.
No need to pry on anything.

Ken, where did you purchase these connectors at? I'd like to get several and just hard wire them to whatever different input/outputs hardware I want to use.

I wired my cabling as below and am still having issues with the scanner not reporting the same numbers as the LM-1 handheld and software:
LM-1 analog Output 1 Red <-> EIO White (Pin 1)
LM-1 analog Output 1 Shield <-> EIO Black (Pin 5)
Originally I just plugged it in and the scanner was saying the AFR was 10.x instead of 20.x on the LM-1. If I disconnected the analog cable from the LM-1, the the scanner would report ~12.63.
So I looked around and I saw some folks who said to scale 0:1V=10:20AFR in the Analog Output 1 in the LM-1 software and program the LM-1. I did that and since then all I get from the scanner is 12.63, but the LM-1 handheld & software still report 20.x, and if I blow on the sensor it drops to 19.x on the handheld but I see no change on the scanner.
I then tried using 0V:5V=10:20AFR, but no change on the scanner.
I've reseated all the cables. I verified I have continuity between the 3.5mm stereo tip and Pin 1 & Pin 5 on the pigtail. I've restarted the scanner software.
What da heck ???
I bet if we had the Molex P/N we could get it off Digi-Key
or some other broad-line distributor. Though likely the
body and pins come separate that way. Probably if you
inspect the housing you will see a Molex P/N embossed
somewhere.
The plug has a small embossed number, 2695.
I don't have mine yet but is this it?

Put 2695 in search and check the first item.
I went to one distributer and the minimum quantity was 800. $5 from HP Tuners might be the best answer.

IT looks very similar to this:

The HP connector has the ramps and polarizing ribs. Not sure if this molex part includes the terminals (the HP plug does not, but the pigtail obviously does)., but the ramps & ribs are optional.
Back to topic, anyone have a clue on the AFR problem?
The analog circuitry on the EIO interface has internal bias. With nothing connected to it, it will hover around 1.24 volts (which for the LM1 is 12.5 AFR).
Which window on the Table display do you have reported as the LM1?
Remember you have 4 A/D input channels, and 4 Table Display locations.
Do you have to program the LM1 to tell it what the output range is or to use the 0-5v output?
Post a screenshot of your settings.

I just checked Digi-Key and...

So if you can get a pigtailed connector for 5 bucks,
that's like getting the wire and labor for -$0.83.
Don't see anything on the Order page except for

Wide Band O2 - LM1
I remember that, but I haven't seen anything regarding how ton config/pick the channels. I have the LM1 connected to AD channel 1, but how does the scanner know to look for the LM-1 on channel 1?Remember you have 4 A/D input channels, and 4 Table Display locations.
Yes. I can configure both Analog Out 1 and Analog Out 2 -Do you have to program the LM1 to tell it what the output range is or to use the 0-5v output?
AO1 defaults to a 'narrowband' setup: 1.1V @ 14.08AFR & 0.103V @ 15.01AFR
AO2 defaults to a 'wideband' setup: 1.002V @ 10AFR & 2.004V @ 20AFR
Each Output also can configure the reponse speed, warmup voltage, error voltage, and whether to mimic high impedance to use it as a narrowband.
I'd love to do so except it's a total PITA to migrate files from my laptop to my desktop due to no network, no serial port on the desktop, and no floppy drive on the desktop.Post a screenshot of your settings.
Lets walk through this a little bit.
Look in the help VCM Suite Help section under Enhanced IO.
There is a picture of the Table display. The bottom six cells will be blank as they have not been configured yet.
Input
Input signal must be a 0-5v+ source.
You can monitor predefined inputs or create your own input type.
Each box in the grid represents an individual input on the interface. Use the picture as a guide.
To add an input to the table display, select the box in the grid that corresponds to the input # you are using on your interface then right click and select insert.
The insert menu will display a list of predefined inputs, which you can select from.
Let me know where you are after these steps.

OOOOH! I didn't realize you had to be in a specific table cell to correlate with a specific interface. I would suggest better delineation of the table cells, or maybe a window title. I could see faintly thicker lines but didn't understand the purpose.
I'll be right back
- Set the LM-1 analog output to use 0-5V=10-20AFR
- Assigned LM1 to the Input 1 cell
AFR stays right around ~19.8, when the handheld is reporting ~20.8. Blowing into the sensor makes the handheld AFR drop, but it doesn't change on the scanner.
The input for the A/D converters is buffered. In the world of electronics things are accurate in the middle range. The buffers cannot quite reach 5v or 0v The absolute maximum it can read is 4.937v (19.8 AFR Lm1) which is the upper rail of the buffer amp. The absolute minimum is .01v (10.02 AFR Lm1)which is the lower rail of the buffer amp.
These are two AFR areas that you will not be operating in.
Your setup is working just fine. Go tune ;D

I didn't get the bung put in today because I was fiddling with this. Since I have cat's, I'm under the impression I'd be wasting my time using one of my O2 bungs - even though the rear's are empty.
I wonder if I can get that sensor put in at the required angle and still have it on the outside of the pipe/collector? It'll probably hit something.
Thanks so much for your patience (I won't go so far as to say understanding :-[) Ken!
Whatever you do, when you get ready to weld in an O2 bung disconnect the negative terminal on the battery and unplug all O2 sensors.
If the welding current finds the wrong path it will destroy the sensors.
I have no patience when it comes to new toys. I shoved my wide band sensor up the exhaust and tied it down with a coat hanger just to play with it ;D
It's installed correctly now but there was no way the sun was going to set without me getting a reading off that sensor
Happy tuning,
Ken
