Crossover Ethernet cable - is it nessecery?

[Mark McLeod]

Actually, a straight cable can be used for both the wireless bridge-to-cRIO AND for the Classmate-to-cRIO connections. A crossover cable will also work. I know the FIRST documentation says to use a crossover cable to connect the Classmate with the cRIO, but it doesn't appear to be necessary.

Just the camera requires the crossover cable.

This is because the Classmate's Ethernet port has the intelligent crossover (IEEE 802.3). Only one of the devices needs to do it in order for either type of cable to work.

Crossovers are to speak to like devices ie the cRio, strait through are for unlike devices, So it is necessary to yse a crossover otherwise your data will not transfer.

So our link between the Classmate and the cRIO (untill we will configure the wireless) sould also be over a crossover cable ?

You can use either type of cable.

Because the classmate is smart enough to auto-configure itself.
