About KNACRO RS422 Interchange TTL Two-way Signal Module
A = R +; B = R-; Y = T +; Z = T- 1, RS422 interface, two-way communication. A B Y Z GND interface, ultra-long transmission 1000 meters. 2, With 15KV ESD protection. 3, The board to increase the high power 10 ohm current limiting overcurrent protection resistor. 4, A TVS diode, anti-lightning, anti-spike voltage. 5, There are 120 ohm termination resistor, effectively reduce long-distance communication echo interference. 6, with power indicator light. 7, RS485 interface with 2-wire and 3-wire mode, to provide GND, you can choose. 8, RS485 interface using conventional 301 terminal, wiring is simple, the user can also self-welding 2.54mm pitch pin. 9, TTL side, using 5V DC power supply RXD TXD compatible with 5V logic signal. 10, Communication speed 2.5MBPS. Note: The default is the pin and the terminal is not welded, the user self-welding. Package Included: 1*RS422 Interchange TTL two-way signal module
