>>Hi,

>>I've got a couple of 9-pin serial to CAT5 adapters (unfortunately
sealed
>>units) and was wondering if anyone knew which wires are used from
the

>>end. I assume that it's not all of them so could I pass the audio
signal

of
>>serial comms were usually talking pins 2,3,7 (on a 25 way) what
about a
>>9-pin?
>>
>>One other thing... can I pass 5 volts down CAT5 safely... would the
>>voltage at the other end of say 100m length of CAT 5 drop
significantly?
>>
>>Many thanks
