AN3485 - RS232/RS422/RS485 communication module for FPGA and SoC boards
The ALINX AN3485 is an industrial communication module designed to expand FPGA and SoC boards with serial interfaces. It offers one RS232 channel, two RS485 channels, and two RS422 channels , supporting 3.3V TTL logic. A 40-pin expansion connector, screw terminals, 120Ω terminating resistors, and ±15kV ESD protection facilitate the development of reliable automation, control, and remote data transmission systems.

Product description: AN3485 - RS232 / RS422 / RS485 communication module for FPGA and SoC boards
The ALINX AN3485 module allows you to connect an FPGA development board or SoC to devices using the RS232 , RS485, and RS422 standards . The MAX3232, MAX3485, and MAX3490 chips handle level conversion, while the 3.3V TTL signals are output to a 40-pin female connector . The RS232 interface uses a standard male DB9 connector and supports speeds up to 120 kbps . Two RS485 and two RS422 channels operate at speeds up to 500 kbps and are available on convenient screw-type connectors. Built-in 120 Ω termination resistors can be jumpered to help adapt the bus over longer distances. The RS485 and RS422 lines also feature ±15 kV ESD protection. A wide operating temperature range from -40°C to 85°C allows the module to be used in prototypes and industrial systems.
AN3485 - RS232 / RS422 / RS485 communication module for FPGA and SoC boards.
The AN3845 module includes one RS232 interface, two RS485 communication interfaces and two RS422 interfaces.
