4 things?
1) you can hook up more temp probes (mx232) has 4 plugs
how do i hook up one more dallas probe (3 wire)
do i need to join them via plug with another probe (ie y split from pluh to 2 probes sharing line?
2) simple using lcdc how do i add +4 to my temp probe
ie [%rnd%[#$AdvDalVal002]%]C=power supply temp
it show 27 but is 31 (4 diff in temp) i want to add +4 to resault shown
3) iv had some problems from day onw with screen being corrupt (letters/graphics etc) every once a time - also sometimes the screen light is off...
does not happen often, (using orb internal cable) switch to usb2 cable external- seems to have fix problem...(still testing)
why does the internal cable (you sell) not work properly?
4) i want to connect 2 buttons to the keypad connectors on orb 232 (4 wires tolal so i can pause a display (or orb) and advance foward.
how do i hook up 2 wire button(x2) and how do i program lcdc to do what i want..
thanks

help with some info
Hi Phillip,
1) As said in your example, you must have the wires going to the same headers and have them share one line. They actually all share the same line, but we only have room for 4 headers. The way the probes are distinquished is they all have a unique address.
2) To add the probes in LCDC, you will just need to do what you regularily do it by scanning the interface. LCDC will add the probes to the list. You will then program the probes like you always did.
3) The internal cable works fine with most people, but some systems generate extra electrical noise than others. Although the interanl usb cable is shielded, it is not completely shielded on the end connecting to the motherboard. Since some systems generate more electrical noise the cable won't fully suppress the extra noise, so you will get some funny things happening like your screen being corrupted. It usually helps if you run the internal cable close to your case/chassis. What will definitely help is you pierce the shielding, and ground it somewhere on your case.
4) First off you will want to refer to section 3 "Keypad Interface" page 16 in the manual at http://www.matrixorbital.ca/manuals/LK_ ... SB_140.pdf This will tell you a little bit about the keypad connector. What you will need to understand is the keypad connector consist of a 6 column 4 row matrix. There is a table in the manual that tells you which row and column corresponds to which character. When you short a row and column, it will generate that specific character. You will need to hook up one end of the button to a row and the other end to a column. You then need to program an event to what you want to do with the keypress. The picture below is an example of this feature. When you press the button, the screen skips forward.
I hope this clears some unanswers questions up for you. If you have anymore questions or concerns, please feel free to post them.
Best Regards,

iv fully tested external usb cable (and now no problems with curruption etc.. lcd work 100%
(how do i hook up shield) is that the silver part?
does the orb internal usb cable have a earth wire to hook up to the usb earth
ie
pin
1 2 3 4 5
1=+5v
2= -data
3= +data
4= gnd (-5v return)
5= nc (? earth)
on question 2.
thats my line for showing the temp i just want to add a fixed number to the result but dont know how?
ie probe give me say 29 (i want to ad +4) to give me 33
or
34 (" ") to give me 38
i dont know how to modify the formula to add to my final results?
------------------------
on the internal usb cable (it short) goes diag from usb header to top lcd panel (mid tower) can i hack apart my usb2 cable which has i think 5 wires (solder the correct connectors) but where does no5 (shield) go.
or (as a quick test) the origional matrix orb internal cable has 5 pin plug (only 4 used) to the lcd and the other end has 4 wires to usb header
if the shieldng(earth) is not connected how do you connect?
and do you have to connect the shield to the lcd (ie the lcd has 5 pins for internal usb hookup?
thanks..

Phillip,
The shielding is the silver part. The shielding needs to be connected to the case(earth ground). Unfortunately, the internal usb cable currently doesn't have an earth wire to hook up to earth ground.
The NC is not a part of the earth ground, and in lots of cases in electronics, they serve some alternative purpose or they aren't connected to anything.
You may get an answer to adding the value for temperature on the LCDC forum at http://forums.lcdc.cc/index.php?showforum=6 Why do you want to add a fixed number anyways?
You can try piercing the shielding on the other end, and run a wire from the shielding to somewhere on your case. The shielding will be attached to the ground plane, but it is not connected to earth ground like how the external usb cable is connected. If you want to connect the wire on the lcd side you may want to run the wire from the shielding to a screw or the case. Basically connect anywhere that is connected to earth ground.
