Only question what cable to use ? Normally all standard RS-485 cables are 2 wires. You need to choose correct wire for extension. If you just take simple 4 cables without shield and no twisted pair then its not good.... Try ethernet cable. It should do the work only that it is too thin...

I recommend ethernet cables : shielded twisted pair cables . we use it previously to carry many signals ( like VGA ) for long distance.
