RS232 to RS485/422 Converter Part no. ANRS485422 This bi-directional combined RS232 to RS485/422 converter is port-powered with an optional external power supply terminal. An internal amplifier supplies power from the RS232 port without initializing the RS232 interface. If the RS232 port is not capable of supplying sufficient power, the external power supply can easily be connected. It supports 2-wire RS485 and 4-wire RS422 communications of up to 300 - 115200bps. A simple and reliable solution for most general and industrial communication needs. Extending communication distance with RS422 Master/Slave Multi-drop configuration with RS485 Pin no.
