Editorial Review Asynchronous Half Duplex Communication To have a PC in charge of controlling a given process in long haul data acquisition and control applications, this converter allows to interface your devices using an RS232 communication link to an RS485 link and vice-versa. Double Protection A built-in transient voltage suppressor (TVS) enables you to get double 600W lightning surge protection against the lightning strike over RS485 link, and 15KV static protection over RS232 link effectively protect your value devices against high voltage spikes. Simple Operation ADDC (Automatic Data Direction Control) function can detect the incoming or outgoing data and automatically switch into the send or receive mode, then you don't have to worry about the data collision problems. For RS485 2 wire system, it only requires three lines (RX, TX and GND) to get a RS232 to RS485 conversion, making it great for troubleshooting the serial system, fully plug and play. Up to 32 devices can be connected on one network to communicate over a single pair of wires (plus a ground wire), so multiple RS485 devices could be connected to one PC without repeater. Specific RS232 Link - 9 pin female port. RS485 Link - 9 pin male port, 4 position terminal board. EIA/TIA RS-232C, RS-485 specification. Transmission Distance - 4000ft over RS485 link, 50ft over RS232 link. Transmission Media - twisted pair (>=24 AWG ) or shielded cable. Applications Computer Factory industrial automation control system Micro controller (MCU) Door safe / Parking system SCADA (supervisory control and data acquisition) ...
