Multiplexing to 48


hi

i in process of building machine identifying cables. plan use arduino send out 48 different signals simultaneously (by cycling through 48 cables). thinking multiplex 48 times, should not hard. on other end of cable plug in small serial lcd , cable number reading. because sending tiny amounts of data baud can slow think. problem these cables 100m long. these cat5 cables.

from understand not able use rs485 , such because of negative swing wouldn't work normal multiplexers.

so either send signal without drivers @ low rate 2400baud, not sure if work , signal scrambled

or somehow find way multiplex rs485 signals.

i trying on budget

any appreciated.


thanks

do mean 48 cat5 cables, or 6 cat5 cables contain 8 cores each, totalling 48 cores?

what purpose of project? continuity testing of 8 cores in each cable? identifying cat5 cable which? if so, why need send data?

i'm going take guess. 48 cat5 cables go wall/floor/ceiling in 1 room. 100m away, 48 cables come out , need identify which. there's no 1 , don't want have keep going room room on , over. can think of way without arduino.
