Let me take a wild guess, you tried to lift your X-monsters and stopped by at Nelson's doc ?
(and don't say you're wearing doggy marshmellow jammies)
chalkandtalk said:On the carte mere there are lots of relays for volume control and switching input. However, I can't find any reference to these on the BOM. Does anyone know the Farnell part number for these?
You will want to use Matsushita TQ2 Voltage is your choice.

I just got me one of these

I used OMRON G6S-2 series 24V in my UGS. pinout is different, but the PCB has the holes (it supports different relays pinouts).
be warned that µC supply voltage is derived from the relay supply voltage. It means that for 24V relays, good heatsinking is needed for the 7809 logic board pre-regulator or thermal protection may be activated... Although this is not a problem nor a reliability issue

If you like images :
there is 3 xformers on the power supply board.
the 2 small ones are 2x24V and they are dedicated to the 2 UGS modules.
the middle and big one is for the digital section, aka µC board and relays. for that one, you choose the woltage depending on the relays voltage, but with a minimum of 2x9V (minimum is the logic pré-régulator, the 7809).
does this help ?

Just in case :
You will find, on the uC/display board, res labelled R-BL, R+BL and RE BL.
As they concern Backlight behaviour, their value depends on the chosen display.
Users of Cristallfontz display (soft 1) will want this values :
R+RL = 22k
R-BL = 9.31k
RE BL = 10R
Optrex users (soft2) :
R+BL=12K7
R-BL=3K92
RE BL=100R
(in this case TIP 29C is not needed anymore and must be left out. Emitter of BC550C should be connected to emitter pin hole of TIP 29C or directly to neighbouring RE BL pin)
Hope it helps.

Non, il est breton ...
I still don't understand why some of you speak about me !!
I can see that fixing parts has started !
Manu,
some of you have found OPTREX ?????? If it's case, let me know, i could be very interested !

Salut,
j'ai pris le mien chez rs (ref 620-4400) lettres noires sur fond blanc - looks

cheap quality relais
Me too!
Ordered last friday,received saturday!
Best buy of the year.

Oui, sans doute ... But size is smaller & with finer caracter too.jacco vermeulen said:
Mais dite, the black & white is the main attraction of the OPTREX display ?
More elegant would I say.
("En Bruges" sounds much better)
Bwana, I agree with you, but what do you mean with "En Bruges"?

Optrex display
Hi Manu,
Do you have a picture of this display?
The datasheet shows not much.

Hi,
Here a little pic.
To give a concrete idea of size , I have put next to the display a box of famous Cachou Lajaunie
You certainly want to see it "in action" but unfortunately my uC board is actually configured for Christalfuntz LCD (Backlight current and connections).
As soon as I find the time to make the changes I ll post a new pic.
