It allows an RS-232 device to reliably transmit data over long distances (up to 4000 feet). The CS485 has many features not normally found in typical line drivers, and is intended for operation in harsh industrial environments. The CS485 may be used in point-to-point applications as well as multi-drop applications using either 4-wire or 2-wire configurations. Up to 32 devices may be connected together on one communication line. The CS485 can also be used as a dual-port half-duplex splitter. As a master, the CS485 can talk to two trunks of up to 31 half-duplex devices. This allows the CS485 to talk to...
