Hello,

I'm a new Prism owner and also Omnisky. After a week of the modem not working, Omnisky tech support got things going today. But after numerous insertions and removal of the modem, I am starting to get a serial error. After firmly inserting the modem three or four times it goes away and starts working again. But I looked at my Springboard pins and noticed that they are not all even but instead some are shorter than others in almost a wave across the pins. Are your pins all even or random heights? Perhaps it's not been the Omnisky modem all along but the Springboard pin connections...

Thanks,
Paul

There are 6 pins on the Springboard connector that are physically longer than the rest: the four pins at each end and two near the center. This is normal and should not be considered a defect. At the moment, I'm away from my main desktop so I can't tell exactly what those pins do but I believe they're the card detect pins, etc. It's all technical stuff anyway...

Ok, I see the six extended pins, the outer edge sets and one set near the middle. However, one pin in from each end is a pin that is shorter than all the other pins. Is this also normal. I'm going to assume it is due to the symetricalness of it. Oh well, wonder what is suddenly causing all these serial errors that are solved by a few attempts at reconnecting the Omnisky?

In case anyone else is experiencing this. It says, Serial Connection Progress --> Error: Serial (0x0308).

BTW, love the technical stuff, I'm an EE...

Is this ok here, or does this fall under the Springboard topic area?

The basic idea (as I remember which could very well be wrong) is that the short ones are power, the long ones are ground, and all the others are bus signals. The idea being that when you plug in a module, you connect grounds first, then signals, then power everything up. The process reverses when the module is removed.

Actually the long ones are power and ground, the medium ones the signals, and the short ones the "card detect" pins.

That way when you insert the card, the power and ground are connected first, then the signals, and finally, when the card is nearly fully seated, the card detect lines. The card detect lines let the Visor know that a new Springboard has been inserted.

Reverse everything for removal.
