Surge Protected Interfaces Protect Equipment, High Speed Data and the Converter Built-in transient voltage suppressor (TVS) enables you to get double 600W lightning surge protection against the lightning strike over RS485 link, 15KV static protection over RS232 link effectively protect the value devices against high voltage. It is suitable for most industrial, commercial, office, lab and network application. DCPC (Data Collision Protection Control) function detects the incoming or outgoing data and automatically switch into the send or receive mode, you don't have to worry about the data collision problems. Wide Voltage: external 9V to 20VDC power supply can be used, and a 110/240V AC to 9V DC power supply adapter is included with this powered serial port converter. Rack-mounted serial adapter box Multi-bus cabling A great feature of the converter is that it provides multiple interfaces for multibus cabling: RS-232 interface is a standard DB9 female connector, and RS-485 / RS-422 side provides RJ45 port and plug-in terminal board, so the RS485 communications cable can connect to either an RJ45 network port or a terminal block . Easy Connection It only requires three lines (RX, TX and GND) to get RS232 to RS485 conversion, great for troubleshooting the serial system, fully plug and play. Applications It’s a quick simple solution for most industrial automation, commercial computer network application, motor control, even tough environments to have PC in charge of controlling a given process in long haul data acquisition and control applications.
