The unit load is a relative parameter that provides a basis for determining the maximum number of connections to an RS-485 bus segment or for specifying the input character- istics of line circuits. A standard RS-485 driver will handle 32 unit loads that could consist of 256 devices with a rating of 1 /8 unit load.
