6.6.2 RS-485 
RS-485 is a standard defining the electrical characteristics of drivers and receivers for 
use in balanced digital multipoint systems. Digital communications networks 
implementing the RS-485 standard can be used effectively over long distances and in 
electrically noisy environments. This Distribution Amplifier (DA) supports up to two 
RS-485 ports allows you to control more than one relative product (ex. Matrix, DA and so 
on). If the master device is specified for LAN, it allows you to control all the series 
devices with web browser. Remember all the ID of each device upon series connection 
has to be uniquely.
