RS485 is renowned for its robustness, reliability, and ease of use. This differential communication system enables data transmission at moderate speeds over long distances, making it ideal for noisy industrial environments.
Features:
- Supports RS485 / EIA-485 standard.
- Designed for industrial communication standards such as MODBUS and DMX.
- Excellent EMC (Electromagnetic Compatibility) and EMI (Electromagnetic Interference) performance.
- Differential signal transmission helps minimize noise and interference.
- Supports data rates up to 35 Mbit/s (short distance) and 100 kbit/s (long distance).
- Multi-point communication: supports up to 40 devices on a single bus.
- Half-duplex mode operation (send or receive at one time).
- Termination resistor option (short R0) for long-distance transmission.
- Signal indicators for RXD and TXD.
- Lightning protection and strong anti-jamming capability.
