1.Description: It is a TTL mutual conversion RS422 module.This module is suitable for 3.3V TTL and RS422 signal interconversion,with overvoltage and overcurrent protection circuit to protect RS422 level signal in real time,to ensure the normal operation of SP3490 chip. 2.Parameter: 1).Product Name:TTL Mutual Conversion RS422 Module 2).Input Voltage:DC 3.3V 3).Clip: SP3490 4).Work Temperature:-25?~85? 5).Work Humidity: 5%~95%RH 6).Size:50.7*26.9*10mm 3.Interface Definition: 1).Module 4P terminal side: 1.1).VCC: 3.3V 1.2).TXD:The TTL (UART) transmission of this module is connected to the RXD receiving pin of the microcontroller 1.3).RXD:The TTL (UART) receiving of this module is connected to the TXD sending pin of the microcontroller 1.4).GND:The ground wire of this module (this ground wire must be connected to the ground of the microcontroller system) 2).Module 5P terminal side: 2.1).R+/A:The A pin of this module needs to be connected to the T+/Y pin of other 422 modules 2.2).R-/B:The B pin of this module needs to be connected to the T-/Z pins of other 422 modules 2.3).T-/Z:The Z pin of this module needs to be connected to the R-/B pin of other 422 modules 2.4).T+/Y:The Y pin of this module needs to be connected to the R+/A pin of other 422 modules 2.5).GND:The ground wire of this module.If some conditions allow,the ground wire can be drawn out as the return path of the common mode signal of the signal.Of course,this wire can not be used when the conditions do not allow it. 4.Package: 1pcs TTL Mutual Conversion RS422 Module

After-Sale Service: Thanks for your purchase. If you have any problem , please feel free to contact us any time. We promise you the satisfying solutions within 24 hours. Practical Design: The converter module has power supply, transceiver indicators, through which you can see the working status of the module, sending and receiving monitoring status. Easy to Use: The serial converter module has a compact structure, light weight and easy installation. 2.54 pitch welding holes are reserved, which is convenient for welding and saves your time. Better Signal Transmission: his module adopts SMD components, in addition to connector pins, it ensures better signal transmission, thereby improving the EMC and other characteristics of the system, so that the module can be used in more and harsher environments as much as possible. High Performance: This module supports overvoltage protection and overcurrent protection, which is convenient and reliable.
