The RS-422/485 standards overcome the transmission distance limitation by using a differential signal for transmitting data and control signals. RS422 (differential) was designed for greater distances and higher Baud rates than RS232. RS485 meets the requirements for a truly multi-point communications network, and the standard specifies up to 32 drivers and 32 receivers on a single (2-wire) bus.
Features and Benefits:
Switch selectable RS485/422 full duplex and RS485 half duplex interface. Surge protectors on both sides. Operates on 5V,50mA DC or 9V to 24V DC. No latency. Indicator LED for power Tx and Rx on both sides helping monitoring and debugging.
Applications:
Used to replace wired RS485 network with RS232 wireless modems to establish wireless link
- Reliable RS232 to RS485/422 half duplex or full duplex conversion.
- Used to connect RS485/422 multi drop device to PC or any RS232 system.
