2-4 Wire 422/485 9 pin Converter - B+B SmartWorx

2-4 Wire RS-422/RS-485 Converter (9-pin) with Auto Send Data Control - B+B SmartWorx The 2-4 Wire 422/485 9 pin Converter from B+B SmartWorx is a compact, port-powered solution that bridges RS-232 devices to robust RS-422 and RS-485 networks. Designed for reliability in industrial environments, this converter transforms TD (transmit) and RD (receive) signals from RS-232 into the differential RS-422/RS-485 formats, enabling longer cable runs, multi-drop networks, and improved noise immunity. With Automatic Send Data Control (SDC) built in, the unit automatically enables the RS-485 driver whenever data appears on the RS-232 side, removing the need for external control signals and simplifying integration into existing equipment. This makes it an ideal choice for automation, process control, data acquisition, and serial device networks where simplicity and dependability matter most. Port-powered RS-232 to RS-422/RS-485 converter that draws power directly from the host serial port, elimin
