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.
