The RS-232 / RS-485 interface converter is designed to implement data exchange between a computer and external devices, such as: IT-3, IT-6, SIT. The converter is connected to a computer via the RS-232 interface at a distance of up to 15 meters. External devices are connected to the converter via the RS-485 interface at a distance of up to 1200 meters. The choice of the transmission direction is carried out by the DTR signal under the control of a personal computer. The device has a built-in set of communication line matching elements (“terminator”), which can be connected or disconnected from the RS-485 line at the user's choice. The converters provide galvanic isolation between the connected devices and the computer and have an additional built-in DC power supply.
