Transcender has a question about cable connection between a workstation and  
a router, there answer is use a crossover cable.

I think it is a straight through cable.

Has any one else used the transcender for the 640-802 exam?

Thanks

cross-over is the correct answer.   If you connect a workstation to a
switch then it is a straight through cable.

The cable type is related to the X cross on the device.

There is a super-simple way to remember:  

1.  Connecting similar devices requires a crossover cable; dissimilar
devices require straight-through.  

2.  Group devices into two groups -- [PCs & routers] and [switches &
hubs].  You can think of the first group as devices that have more
control over the network and the second group as devices with less
control.  Or the first group is smarter, or . . .

3.  A wire between these two groups is a straight-through; a wire
within a group is a cross-over.

Thanks for all the help.


Re: Transcender Cable Question
DTE - DTE = x-over

DTE - DCE = straight

certain devices have their pins wired in a
particular way

as an example ,  if pin 2 was TX and pin 3 was RX
and the other connected device ALSO had it's pins
wired the same ( pin 2 was TX and pin 3 was RX),
it wouldn't work with a straight cable as TX would
connect to TX and RX to RX.....
here a x-over cable would be needed!

on the other hand , if the connecting device had it's
pins wired the other way ie/ pin 2 RX and pin 3 was TX,
then a straight cable will be needed, giving you the correct
pin alignment....

ie/ TX ----> RX and
     RX <----TX

my 2 cents
