Specification
1. It has three LED indicators: RXD, TXD and power supply, and serial port input protection;
2. The chip has a swing limiting rate driver to minimize EMI and signal reflection caused by improper terminal matching cables, so that the error free signal transmission rate can reach 500Kbps.
3. The receiver input impedance with 1/4 unit load supports multi machine communication and can be connected to the bus of up to 128 devices.
4. The working temperature of industrial chip can reach - 40 ° C to+85 ° C.
5. This module can be hot swapped without the signal blocking phenomenon caused by hot swapping of other 485 chips.
6. 1200 terminal resistance (more stable and lower bit error rate when the line length exceeds 200m);
7. With transient suppression TVS 600W diode, overvoltage protection performance is better;
8. 102 current protection resistor is used to improve 485 signal integrity;
9. All RS485 and TTL signals are routed on one side to ensure signal quality and improve signal integrity;
