Analog Module?

In the past we've use a ribbon cable, and relocated the analog breakout into a separate plastic box to protect both the module and the connectors. However, I don't think that is what was being asked.

According to "How to Set Up Your Robot Control System", the cRio can be set up with 9201 (analog) modules in slots one and two, 9403 (digital) modules in slots 4 and 6, and a 9472 (solenoid) module in slot 8. The document also says you have to attach the analog breakout to the module in slot one. From what I can see this is not exactly true.

Example: To create a new gyro you would normally do

Gyro spin = new Gyro(1);

Where "1" is the analog channel, the first analog pin on the analog breakout. But you can also do

Gyro spin = new Gyro(2,1);

where 2 is the second cRio slot, and 1 is the 1st channel/pin on that slot.

To me this kind of implies you can move all your analog stuff to slot two, digital stuff to six, etc.

Haven't tried it myself (we don't even have a robot yet... don't ask), but might be worth looking into.
