This module has overvoltage and overcurrent protection circuit real-time protection RS422 signal level, to ensure normal operation of MAX490 chip,this module except pin outside use SMD components to ensure better signal transmission, and improve the system's EMC characteristics. So the module as possible applications in more and more bad environment. Module interface definition: Module 4P terminal side: VCC, +5V TXD, the module's TTL (UART) transmission, connecte SCM's RXD receive pin RXD, the module's TTL (UART) transmission,connecte SCM's TXD receive pin GND, this module's grand wire (the line must be connected with the grand of single chip system.) Module 5P terminal side: R+/A, the A foot of this module,need to connect the other 422 modules' T+/Y pin R-/B: the B foot of this module,need to connect the other 422 modules' T-/Z pin T-/Z : the z foot of this module,need to connect the other 422 modules' R-/B pin T+/Y :the y foot of this module,need to connect the other 422 modules' R+/A pin
