Description

Amazon 【RS485TTL】 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. Has RXD, TXD signal indicator light, monitor send and receive status. Package Contains: 5 pcs TTL Turn RS485 module. 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 the test, it is recommended to use within 800 meters, more than 800 meters, please add repeaters). 【Easy operation】 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.
