• The module is suitable for 3.3V TTL and RS422 signal mutual conversion, RS422 level is full-duplex level signal, the use of this module can be achieved SCM serial port and RS422 signal conversion.
• With over-voltage and over-current protection circuit real-time protection RS422 level signal to protect the MAX490 chip's normal work.
• The module except for the pin, Use SMD components to ensure better signal transmission, thereby enhancing the system EMC and other characteristics, the module as possible in more harsh environments.
• With power and send & receive Indicator lights. The back of the product with wiring diagram.
