Installation:::...

I mentioned that you could buy an internal USB cable, but luckily we had one sent with the kit.

One thing disappointed me about the supplied leaflet which explains how to fit the cable, and that is that the diagram is wrong. Well, not wrong as such, just rotated through 90 degrees when compared to the actual orientation.

If you look at the top arrow in the picture below it makes it look like the header is in the bottom right hand corner of the board when in actual fact if you look at the lower arrow you can see that it's on the bottom left. Not a problem to anyone who has an idea what they're doing but confusing to a less experienced user I should imagine. It may be that this is a generic leaflet and that some of the displays are this way up, but It need changing to stop the "trial and error" approach to finding the proper pins.

For some reason, these USB connectors often get people stressed, but it helps if you understand how the USB pin-outs are arranged.

Most internal USB headers have nine pins and look a little like this:

The first thing you should know to help simplify things is that the pin that's off on its own, no matter which way up the header is, is not connected to anything and is used as a key to stop you attaching one-piece connectors the wrong way around, or the gap is depending how you look at it.

The next thing that will help demystify things is that this is a dual USB header, so there are are only four pins per USB port, each of which is duplicated. So, in a nutshell, we have only four pins to worry about.

Assuming the motherboard manufacturer has done things by the book, the pins should be arranged like this:

So as you can see we have a pair of +5V pins on the right (sometimes shown as VCC in your manual), then a pair of D- (Data-), then D+ (Data +) then finally a pair of ground pins.

Below are the four connectors from the end of the internal USB cable.

So you could connect the pins like this:

Or alternatively you could connect them like this:

Either way works fine just double check in your motherboard manual that the pins haven't been assigned in a different order. If so, the same principle remains, just reorder the connectors to suit.

I've already mentioned the possible problems fitting the MX with drive rails, though apart from this, physically installing the unit is as straightforward as removing and refitting the four screws in most cases.

Trying to plug in the floppy power connector (if you need to) is a right royal pain in the Donkey if you try and do it after the MX is fastened in place, and you probably will as most cables won't reach far enough to connect them from the front before you fit it. A small extension lead would definitely be a welcome addition here.

This done you just need to reboot your PC and follow the onscreen instructions, pointing your PC to the drivers in the "USB Drivers" folder on the installation CD. Two entries are created in device manager, a virtual COM port in "Ports" and an entry in your "USB Controllers".

 

 

The final step is to install LCDC. This is much like installing any software other than you need to get an activation code based on the CD key number, then let the software detect your MX before you go in and set it all up.

This is made simpler by the "Getting Started" screen that you can access on the way in, or later on, but make no mistake, some of the settings are bordering on complicated and require some thinking about. You can get things running in basic mode quite easily, but modifying things and creating new profiles and sequences isn't for those who don't enjoy some figuring things out.
