RS422-TTL Module, Full Duplex, RS-422

Description

• RS422 interface, two-way communication, full duplex. A B Y Z GND interface, GND can be used, ultra-long transmission 1000 meters
• with 15KV ESD TVS diode, anti-lightning, anti-peak voltage
• On board 10 ohm current-limiting, overcurrent protection resistor
• 120 ohm termination resistor, effectively reduce the long-distance communication echo interference
• On board power indicator
• RS485 interface with 2-wire and 3-wire mode, to provide GND, can be chose to use
• RS485 interface using the conventional 301 terminal, wiring is simple, the user can also self-welding 2.54mm pitch pin
• TTL side, using 5V DC power supply RXD TXD compatible with 5V logic signal
• Baud rate of 2.5MBPS
• Randomly send MAXIM or SIPEX ICs board.
