Function: This module can easily achieve the conversion between 232 signal and 485 signal, with industrial grade protection and stable and reliable performance.

Application scenarios: Suitable for multi device networking scenarios such as industrial automation, intelligent buildings, PLC communication, RS232/485 protocol conversion, etc., stable and reliable.

Product Features

1. All chips use brand new original industrial grade chips for ultra long distance transmission.

2. Equipped with three LED indicators for RXD, TXD, and power supply, and serial input protection;

3. The chip has a limited swing rate driver program that minimizes EMI and reduces signal reflections caused by inappropriate terminal matching cables, resulting in an error free signal transmission rate of up to 500Kbps.

4. Receiver input impedance with 1/4 unit load, supports multi machine communication, and allows connection to a bus with up to 128 devices.

5. The working temperature of industrial grade chips can reach -40 ℃ to+85 ℃

6. This module can be hot plugged without the signal jamming phenomenon that occurs during hot plugging of other 485 chips.

7. Equipped with a 120 Ω terminal resistance (more stable and reduces bit error rate when the wire length exceeds 200 meters);

8. Using transient suppression TVS 600W diode for better overvoltage protection performance;

9. Using a 10 Ω current protection resistor and surface mount design to improve 485 signal integrity;

10. RS485 and TTL signals are all single-sided wired to ensure signal quality and improve signal integrity;

11. Large area copper laying to prevent signal interference;

12. Supports multiple baud rates:

300/600/1200/2400/4800/9600/19200/38400/57600/115200/230400/460800/921600, etc.:

Wiring Instructions

232 end:

R and T: The reception and transmission of RS232 bus require communication with other RS232 modules, that is, RX is connected to TX.

G is the ground of terminal 232, connected to the external negative pole;

V: The positive pole of the module's power supply is connected to the positive pole of an external power source;

485 end:

A and B: The DATA+(A) and DATA - (B) of RS485 bus, 485 requires A to be connected to A and B to be connected to B;

G: RS485 reference ground, generally not connected;
