Re: Is it possible to power 2 standard QLs with a single PSU if...
Francois, I might have a last spare PSU still available. It's handmade and provides more power (2.5 Ampere or more). I've sold 4 similar PSUs. A person asked for it years ago. I may ask that person: he might no longer be interested. Sure I would be interested, however I am located in Canada, so it ...

Re: Is it possible to power 2 standard QLs with a single PSU if...
Common GND is in fact either side of the AC transformer output, which one doesn't matter (BTW I managed to scavenge several 12V transformers from some cheap Chinese Christmas lights my wife wanted to throw away - They seem to be a good source for this and are even outdoor rated ;) ). The Tetroid (a...

Re: Is it possible to power 2 standard QLs with a single PSU if...
Even if it worked for some time, I wouldn't load that good 'ol PSU with nearly twice its rated current. The switching regulators do in fact slightly reduce current input, but not that much. Even if you made it work, you'd still be faced with the nonstandard power connector. Stitching together a 9V-...

Is it possible to power 2 standard QLs with a single PSU if...
... if both QLs are equipped with Teroid switching regulator ? Would the better efficiency of the switching regulator be enough to reduce power consumption by half ? These PSU are difficult to come by so using a single one for two QLs would be nice. What if one of these QLs has a GoldCard ? (My unde...

Re: Q68 netwrok port hardware
It does. When I apply 3.3V to the QLnet pin, the value becomes 57.Peter wrote: That's correct in inactive state (Bit 0 = 0). When you pull the line high, it should change.
Let's wait for the BAT43.

Re: Q68 netwrok port hardware
Sorry, these sockets were bought at a local electronic shop, so I have no number or spec sheet.Derek_Stewart wrote:Hi François,
Can you tell me what type of socket you are using?

Re: Q68 netwrok port hardware
What you could do, is to remove your circuit and just apply GND or 3.3V to the QLNET line. Then check if you see bit 0 of PC.MCTRL (at $18020) change accordingly. Make sure no network driver is loaded, so the Q68 does not attempt to drive the line high while you apply GND! Hi Peter, is PC.MCTRL a b...

Re: Q68 netwrok port hardware
Hm, my money so far is on the socket. But hard to tell as I couldn't find your model anywhere. All similar looking ones had one contact come out on the top, which doesn't seem to be the case with yours. Cheers, Marcel These sockets were very easy to figure out as the bottom is open so you can see w...

Re: Q68 netwrok port hardware
I checked them when I built the interface, but I will check again. I will order a few BAT43.Derek_Stewart wrote:Hi François,
Are the connections to the Network sockets correct?
