Description:
- This module realizes the mutual conversion between TTL signal and RS485 signal, but we must know that 485 is half-duplex communication. This communication method can realize two-way communication, but it cannot be performed simultaneously in two directions, and must alternate in turn.
- Each end 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.
- Baud rate: 110~128000bps
- Compatible with 3.3V and 5.0V power supply.
- Compatible with 3.3V and 5.0V signal.
- Industrial grade design, super anti-interference ability, and more effective 485 lightning protection design, can be used in industrial and field harsh environments, operating temperature is -40 ° C to +85 ° C, transmission distance up to 1, 000 Meter (tested with 850 meters of 2* 1.5 cable, it is recommended to use within 800 meters. Please add repeater over 800 meters)
- Designed with a half-hole process, the plate thickness is 0.8 mm, which can be easily used as a motherboard or solder terminal on it.
- With RXD, TXD signal indicator, visible of transmission and reception status
Features:
- This module fully considers the 485 bus lightning protection design and anti-interference design. When transmitting in the field for a long distance, the module's "??? " end (3 Chinese characters on the left side of B- end) is connected to the earth, which can play a good role in anti-interference and lightning protection. It is not necessary to connect the earth when using short distance transmission indoor.
- Use standard 2.54 spacing design for your secondary development.
- With a 120 ohm matching resistor, shorting R0 can match the resistor, and short-circuit is recommended for long-distance transmission.
- Support multi-machine communication, allowing access to buses of up to 128 devices
- This module can be hot swapped, and there will be no signal embolism caused by hot plugging like other 485 chips.
- Large area copper plating to prevent signal interference
What's in the Package:
- 1pcs RS485 to TTL Module
