Port Powered RS-232 to RS-485
Part number: ATC-106
In Stock : Available

product overview

ATC - 106/106N interface converter can send the signal RS–232C serial port data (TD) and receive data (RD) into two line balance of the half-duplex RS - 485 signal. It is the best choice of a remote Control device or point to multipoint communication bus. The interface transition device don't need ac/dc converter, it can be directly from the Data within the RS-232 port transmitter data (TD), request to Send (RTS) or Data terminal ready (DTR) to obtain power. It also have the Automatic Send Data Line Control function. When to Send and receive Data, do not need the RTS control. So the power supply from serial port and Automatic flow Control makes you don't have to reset the hardware or install software. Improve the surge protection, can ensure the safety of the RS-485 network.
