The LD-02 is used in multidrop applications when a large numbers of units have to communicate with a main computer; for example in access control systems, weigh-scale systems or other types of measurement and data acquisition solutions. The LD-02 can be connected to equipment that uses the RS-232/V.24 or RS422/485 interface.
Westermo's ±10 mA balanced current loop (W1) transmission technique makes it possible to transmit data up to 18 km at low data rates. At shorter ranges, transmission rates up to 38.4 kbit/s can be achieved.
