The first thing you notice when you power on this unit is the new splash screen, this time it incorporates the Matrix Orbital logo, rather than just being plain text.
The latest versions of LCDC include options to take advantage of the new features incorporated into this new unit from Matrix Orbital, without one of these newer versions of LCDC you will not be able to use the advanced features of the unit, so you better get up to date!
First I am going to take a look at the temperature sensing facility of this new unit. You can have upto four temperature probes plugged into the unit, but you can have upto 32 in total (when connected together), the connectors used are the same as those used on WOL cables used to connect your NIC to your motherboard to take advantage of the wake-on-lan function, so if you want to make your own temperature sensors you'll have to get some of these leads from somewhere.
These are the temperature sensors that the module uses, they are the Dallas Semiconductor DS18S20, available from Maplin and all other good electronics retailers. They are in the same package as a normal sized 3 pin transistor (TO-92), so they are not the smallest thing, but a good enough size for putting on the back of graphics cards or wedging into CPU heatsinks etc. Rumour has it that you can sand the sensors down to give them a lower profile though. Matrix Orbital sell these temperature sensors as well as all the other accessories so you can buy some if you are unsure about making your own. If you do want to make your own though, it's very simple, its just 3 wires, no other components involved. Right, so plug your pre-made sensors into the back of the unit and fire up LCDC.
Go to the configuration section of LCDC, and select the Dallas one wire option from the Advanced MXx features section. Then you should click the 'Scan interface' button, which will bring up the following dialog...
LCDC has found and confirmed that I have connected 3 sensors to my MX2, and they will be added for use when the close button is pressed. You can then give your sensors names, so that you will have something to refer to them by (other than the sensor's unique ID).
It really is as simple as that, with that done the output of each of the sensors just appears as another variable in the screen builder, which you can then insert to your screens and you have your temperatures!
Thats the temperature functions covered, so now lets take a look at what's special about those fan headers.
