Antec MX-1 External Drive plug problem
I've had this unit for about a year without any problems. A week ago, the
unit would not switch on and I tracked the problem to a broken Switching adapter. The model is PA-225 produced by Vantec (Opti) and I found a replacement online and it arrived yesterday. Exactly the same model number and identical in all respects except for the plug that inserts into the Antec unit. Both have 4 pins but the new model has 4 thick pins roughly evenly centred whereas the original has two pins on each side and a lug at the top. The origina is more like a DIN plug and it does insert into an S-video connector. I've never before seen the new plug before. I've searched the net but cannot find images of the particular plugs I have (part of the problem is finding the right keywords to enter into Google). I'm a bit p*d off that ordering the same model number that I have came with a different plug. It might be possible to find an adapter but I wouldn't know where to look. If anyone has any familiarity with external drive plugs, I'd surely be grateful for some advice on what these types of plugs are called or wheter there might be an adapter available. |

If anyone has any familiarity with external drive plugs, I'd surely be grateful for some advice on what these types of plugs are called or wheter there might be an adapter available. The picture of the MX-1 is showing a mini-DIN connector. With four pins, it could be +5,+12,GND,GND for example. I don't know which pin is which though. http://www.antec.com/Believe_it/product.php?id=NDc= Some pictures of mini-DIN connectors are here. http://en.wikipedia.org/wiki/MiniDIN There is a reference here to a "snap n' lock" dc power connector or "power mini-din". It has thicker pins and I don't see an internal key in this one. The thicker pins would prevent it from being plugged into an S-video connector by accident (by a child), and the thicker pins may allow more contact area and a higher current rating. http://en.wikipedia.org/wiki/DC_connector This is an example of a 4 pin mini-DIN male, at $1.32 each. http://search.digikey.com/scripts/Dk...ame=CP-2040-ND The datasheet for that mini-DIN, says the pins are rated for 2 amps max. http://www.cui.com/pdffiles/MD-40.pdf I'd also be a little worried, about whether there are standards for what power is on what pins. You can certainly measure the new adapter (being careful to not slip off the pins or short power to the shell), but because the old adapter is dead, it is going to be pretty tough to verify what is what. I'd probably open the enclosure, and take a guess based on the wiring inside. Using an ohmmeter, you could buzz (do a zero ohm check) from the 15 pin pad pattern in this picture, back to the four pins on the mini-DIN. Wikipedia.org, in the SATA article, has a pinout for the 15 pin SATA power. So you'd be able to select the 5V pins or the 12V pins in the Wikipedia diagram, then touch the four pins on the mini-DIN on the back of the MX-1, and figure out the assignment. http://www.virtual-hideout.net/revie.../images/18.JPG A new MX-1 here, is $53. http://www.newegg.com/Product/Produc...82E16817371008 Good luck, Paul |

From you links I have found that was sent this one: http://en.wikipedia.org/wiki/File:Mi..._connector.jpg The wiring is shown on the side of the switching unit. I'm not sure whether you can break these things a part but I will attempt the broken one first and see whether I can swap the exit cables. It would be easier if there was an adapter that converted one plug to the other. Regards, Peter. |

My guess is, getting that adapter open, could be harder than you think. If the manufacturers wanted to be *******s, they could use plastic cement to hold the two halves of the adapter together.

Paul Typically they will use ultrasonic welding to fuse plastic case parts during manufacturing. It is very quick and involves no nasty-smelling toxic solvents as the old method did. Then again, if the maker is in China they may not care overly much if the old method is a hazard. -- John McGaw [Knoxville, TN, USA] http://johnmcgaw.com |

It is welded but it snapped open quite easily. There are only 3 wires attaching to the circutboard so I will have to test which pin is not used. I'll get my multitester and soldering iron out later today. |

There are only 3 wires attaching to the circutboard so I will have to test which pin is not used. I'll get my multitester and soldering iron out later today. Success!! Both units were exactly the same inside. Cracked the second case when opening it and used the old one to re-house the circuitboard. Completed the soldering and it works perfectly. Thanks very much for your help. |
