Using PSUmoni on Win7 - one way that will work for some

Hi All,

Recently upgraded to Win7 Ultimate (32bit) and found, like many, that although the application runs, it does not talk to the PSU (the lower left hand corner in the app states, "USB not connected").

Windows XP mode has solved this issue for me (so far so good, behavior has been consistent for 2 days). Note - I do not use the Carnetix PSU (2140) to do sleep/wake-up via USB, that's why I say 'solution for some' as those that are using this functionality are likely still out of luck...not to mention anyone whose hardware does not support virtualization.

I actually don't use the 'run applications from Win7 once installed via XP mode', as I found that the USB connection still does not work (for those that want to try, you need to copy the application short cut to 'all users' in the start menu, and then power down the virtual machine before the application icon shows up in the Win7 start menu). So, instead, I install PSUmoni via XP mode, and then 'attach' the Carnetix USB device via the virtual machines settings. At this point the application is able to talk to the PSU. I now make any changes that I need (soft jumpers, etc.), click 'update' and close the application and power down the virtual machine.

For me - this is all I need. The PSU turns on/off the PC as I want it, and I don't need to have PSUmoni running in order for it to do so. Again, I'm only using the APCI wires for turn-on/off, so I only need the very basic functionality once I have all of my options set correctly.

If I need to make further changes, or want to see what power consumption is, I restart the virtual machine and fire up the application...all of which takes about 15 seconds (I use SSD, which I believe helps a lot here).

Anyway, thought I'd share as it may help some.

Managing multiple 2140's via one PC.

For those that have more than one 2140 installed and want to use both: you need to disable one in device manager before managing the other. Once you've configured the one, disable it, and enable the other one in device manager, restart PSUmoni, and you can now configure the 2nd one.

Please excuse me if this is a stupid question. I am new to this and have just purchased a P2140 from a guy on ebay. I received the unit today along with two cables with connectors (obviously one for each of the two ports on the unit.)

My question is, does anyone know where I can find a colour coded wiring diagram for this or can someone explain the use of each of the colours to me? I am unsure of which set of wires I need to run to the battery and which set need to run to the computer? I have looked on the carnetix website and searched the forums. The only diagrams I have found are the ones listed above, however they do not display the colours at all.

The setup of cables is as follows:
Small connector
- Black (earth) x 2
- Red (positive) x 2
- Yellow (constant?) x 1
- Blue (?) x 1

Bigger connector
- Red x 2
- Black x 2
- Brown x 1
- Blue x 1
- White x 1
- Green x 1

I will be purchasing a mac pac as I will be running a mac mini. I presume this will take up one of the connections on the unit and eliminate one of the cables supplied?

Can anyone lead me to a wiring diagram for the p2140 showing what each coloured wire is to be connected to? I bought a used one from ebay which came without a diagram. I looked on the carnetix webiste with no luck.

It came with two sets of cables, one which I presume is to give the unit power and one to pc. I am unsure which is which? There is two different size connectors which you probably already knew.

Also I presume if I purchase a mac pac to run a mac mini one of these sets of cables will be eliminated from the unit and be replaced with the mac pac?

the user manual has the details. Starting on page 13, I believe.

I was able to run my $150 carnetix 2140 on Windows XP with no problems. I have recently upgraded to Windows 7 from the more 12 year old XP. everything works fine except the 2140. I have posted on their forums and contacted them directly via E-mail. In one reply I was told there will be a beta for Vista/windows 7. This was in Junuary 2010. I know I am not the only one running Windows 7 in their vehicle because when I go to the Carnetix support forum I see thousands of posts and views, but carnetix is not taking this topic seriously. I saw one post where the site admins made comments about currents events, when a customer asked about windows 7 support. ... not funny guys, not professional either!

Post A Mexican newspaper
A Mexican newspaper reports that bored Royal Air Force pilots stationed on the Falkland Islands have devised what they consider a marvelous new game. Noting that the local penguins are fascinated by airplanes, the pilots search out a beach where the birds are gathered and fly slowly along it at the water's edge. Perhaps ten thousand penguins turn their heads in unison watching the planes go by, and when the pilots turn around and fly back, the birds turn their heads in the opposite direction, like spectators at a slow-motion tennis match.Sprint Woman Shoes black-blackSprint Woman Shoes blue-aqua-graySprint Woman Shoes Fuchia-gray-lilacThen, the paper reports, "The pilots fly out to sea and directly to the penguin colony and overfly it. Heads go up, up, up, and ten thousand penguins fall over gently onto their backs."

Smile An escaped convict
An escaped convict, imprisoned for 1st degree murder, had spent 25 years of his life sentence in prison. While on the run, he broke into a house and tied up a young couple who had been sleeping in the bedroom.FiveFingers KSOVibram KSOVibram FiveFinger KSOHe tied the man to a chair on one side of the room and his wife on the bed on the other side of the room. The convict got on the bed and it appeared to the husband that he may have been kissing her neck. Suddenly the convict got up and left the room. As soon as he had a chance, the husband made his way across the room with the chair in tow, and turned to his pretty young wife, bound up on the bed in a skimpy nightgown. He whispered, "Honey, this guy hasn't seen a woman in years. I saw him kissing on your neck and then he left in a hurry. Just cooperate with anything he wants. If he wants to have sex with you, just go along with it and pretend you like it. Whatever you do don't fight him or make him mad. Our lives depend on it.""Oh honey", the wife said, spitting out her gag, "I'm so relieved you feel that way. You're right, he hasn't seen a woman in years. But he wasn't kissing my neck... he was whispering in my ear. He told me he thinks you're really cute and asked if we kept the Vaseline in the bathroom."
