is_customized: Yes

Product introduction:

The module uses a black backplane-circuit board, high quality, standard 3.81mm plug, another pin interface, RS485 transceiver automatic switching, no direction switching, dual LED indicators on the board indicate the status of receiving and sending, and a power light indicates power supply Status, on-board voltage regulator chip supports 3.3-5V wide voltage power supply

Supplied (not soldered): standard 3.81mm industrial plug, 2.54 pitch pin

The transparent transmission module realizes the mutual conversion of TTL level signals and RS485 level signals, and 485 is half-duplex communication. This communication method can realize two-way communication, but cannot be performed simultaneously in two directions, and must alternately and alternately Each segment of the communication channel can be either a transmitting end or a receiving end, but at the same time, the information can only have one transmission direction. This module realizes the automatic flow direction control of RS485 signal, and the transmission and reception direction is automatically switched. This module is the same as the operation serial port. It adopts imported chip, industrial grade design, anti-jamming type and copper plating method, has high EMI and EMC, makes it strong anti-interference ability, and adopts powerful 485 bus lightning protection design. It can be used in industrial environments and in harsh outdoor environments. The transmission distance can reach up to kilometers (using 850 meters of 2*1.5 cables for testing, it is recommended to use within 800 meters, more than 800 meters for repeaters). When transmitting in the wild for long distances, the "connected earth" end of the module is connected to the earth, which can play a good role of anti-interference and lightning protection, making the 485 bus more secure; the indoor short-distance transmission can not be connected to the earth. With RXD, TXD signal indicator, the receiving and receiving status is unobstructed. It can be hot swapped without signal embedding.

Tips:

This module can realize the mutual conversion between TTL signal and RS485 signal, but 485 is half-duplex communication. This communication mode can realize two-way communication, but it can not be carried out in two directions at the same time. That is, each end of the communication channel may be the transmitting side or the receiving side, but at the same time, the information may have only one transmission direction.
This module realizes the mutual conversion between TTL signal and RS485 signal, no need to "receive - send" control, use this module as you operate the serial port as simple, compatible with 3.3V and 5.0V power supply, compatible with 3.3V and 5.0V signal; Imported chip, the performance is very stable, to industrial design standards; anti-interference ability, while more effective 485 mine design, in the industrial field and field harsh environment, the transmission distance of up to 1000 meters Of the 850 meters of 2 * 1.5 cable to do the test, it is recommended to use within 800 meters, more than 800 meters, please add repeaters).

Product Features:

Fully consider the 485 bus lightning protection design and anti-jamming design, long-distance transmission in the field, the module's "earth" side access to the earth, can play a very good anti-jamming and lightning effect, 485 Bus more secure; indoor short distance transmission can not access the earth.
The use of standard 2.54 pitch design, to facilitate your secondary development.
With 120 ohm matching resistor, shorted R0 to enable matching resistor, long-distance transmission of the proposed short-circuit.
Support multi-machine communication, allowing access to up to 128 devices on the bus.
Support hot-swappable, there will not be other 485 chip hot plug signal plug dead phenomenon.
Large area of copper, to prevent signal interference.
Half-hole process design, thickness 0.8mm, can be easily used as a mother board, but also welding terminal use.
With RXD, TXD signal indicator.

The RS232 to RS485 module is an electronic module used to achieve media conversion between RS232 and RS485 protocols. RS232 and RS485 are two different interfaces, and RS-232 can only transmit 10 meters. In the case of long communication distances, it is usually necessary to convert RS232 signals into RS485 signals. Because the RS-485 interface can transmit 1200 meters. The RS232 to RS485 module has the characteristics of strong flexibility, long extension distance, fast transmission speed, and strong anti-interference ability, and is widely used in various industrial automation control, LED display screens, intelligent building monitoring, power and electrical fields.
