7i80 and 7i77

Is it right, that the 7i77 have no LEDs for the digital in and outputs. If yes I must make a small Input and outputcard to see, which of the connectors is switched. I think I can see it on the Screen, but if I work behind the machine I must see which sensor is switched, and which actor (most solenoid valves) is activated.

Depending on the application, and the budget, you might want to look at the 7i64. That has LEDs on the inputs and outputs, and the IO is higher-power than the 7i77, and also isolated. It isn't a very cheap board, though, and it still typically needs a 7i77 to plug in to.

I installed an Precise (32-bit) system and rt-preemt kernel based on Andy description.
It works well, but I can not find the 7i80 bit file. Where can I download it?

Thanks

The 7i80 uses non-volatile firmware, like the 5i25 and 6i25. So you don't need to load a bitfile every time.

You can change the firmware with the "mesaflash" utility.

If you download www.mesanet.com/software/parallel/7i80.zip

Then if you expand it you should find the mesaflash utility in 7i80/utils/linux. Mesaflash will probably have lost its "execute" bit due to being zipped, "chmod 777 mesaflash" will fix that, or a right-click in the GUI.
The bit files can be found in 7i80/configs/ There are a lot more configs for the 7i80 HD than the 7i80DB

Many thanks, I do it...

I have an additional question. Is it possible to connect a differential encoder to the single ended inputs of the 7i76/77 card. Or otherwise to connect the A.B_ and A_.B together on the A and B inputs of the card?
