Application topology

RS232 To RS485 Conversion

Access to a host, PLC or other devices with RS232 port, the RS232 can be converted to RS485 port for point-to-point half-duplex communication with external RS485 devices.

Access to a host, PLC or other devices with RS232 port, the RS232 can be converted to RS485 port for point-to-multipoints half-duplex communication with external RS485 devices.

Application Examples

The RS232 TO RS485 converter can be widely used for point-to-point, point-to-multipoint, long distance cascaded communication network between two hosts, or between host and MCU/Peripheral. It also can be used in the application scenarios that require RS232 to RS485 conversion such as Industrial Automation and IoT.

Dimensions

Note: RS232 TO RS485 (B) and RS232 TO RS485 (D) are based on the same case mold and have the same outline dimensions, while model D has additional indicator holes.
