XY-017 Serial Port to RS485 UART Converter Board Module RS485 to TTL


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:
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 motherboard, but also welding terminal use.

With RXD, TXD signal indicator.

Operating voltage: compatible with 3.3V and 5.0V

Support baud rate: 110-256000bps

Operating temperature: -40 Celsius to +85 Celsius

Communication signal: compatible with 3.3V and 5.0V
