I have an RFID reader attached to my adruino with 4pair cat5 cable. usng only 2 pair. blue = 5v, wblue = enable, orange = sout, worange = gnd. the Reader doesnt seem to be sending data when i connect it to the end of the cable (about 50ft) but works fine when i plug directly into th arduino or a breadboard. same settings same code same wireing... the variable seems to be the dstnce. is 50ft really that far???
any input would be greatly appreciated. thank you.
PS. Im using the RX2 port on a mega.
