    Give a man a fish, feed him for a day. Teach a man to use Google and he can find his own directions to the supermarket. I too needed this information once and Google was happy to help me. You might also want to read up on straight through cables as well. Although, in these days of Auto MDIX I don't think you see as much of a need for either type.

      Rollover Cable - type of null-modem cable that is most commonly used to connect a computer terminal to a router's console port

      Crossover Cable - used to connect computing devices together directly where they would normally be connected via a network switch, hub or router.

      Never seen on used for the other in the 20 years I have been in the IT field.

          FYI, a crossover cable is also refered to (though not commonly) as a null hub cable.

          2 2 was 1 2.

              well there are 3 types patch, crossover, rollover.
              patch cable connects dissimilar devices ie
              router>switch>pc
              It's to do with the transmit/receive wires of the cable, patch cable crosses the two
              transmit>receive
              receive<transmit


              cross over cable connects devices of a similar type together.
              pc to pc, switch to switch, router to router.
              cross over is used because when the device is similar a patch would connect transmit to transit and receive to receive, so these need to be 'crossed over'


              A rollover cable, however, is used to connect a computer's serial port to the console prtt of a router or managed switch (with a dongle). It is wired with the to ends completely the reverse of each other:
              So like before patch and crossover were swapping transmit/receive at different ends a rollover swaps all the wires.

              I do tend to think 'outside the box' so others may not always share the same views.

                  Did you even look at the Google link provided by Nonapeptide. It answered the question when I looked at it. A search of the Forums would also have given you an answer as this had been discussed 4 or 5 weeks ago. S E A R C H , the forgotten tool. It is so much easier to be hand feed.

                        Sorry to labour the point but this attachment shows the first page of the search from Nonapeptide's Google link. (I have added the yellow highlighter to make it easier to see.)
