The entire network has only one 3.3V and 5.0V power supply, RS485 signal is fully compatible with automatic flow control module. No "receive - start" control, this module is as simple as the serial port operation. Highlights: (1) Compatible with 3.3V and 5.0V power supply. (2) Compatible with 3.3V and 5.0V signals. (3) The absolute use of imported chips, industrial design, anti-interference ability, while using a more effective lightning protection design, can be used in industrial sites and harsh field environments, operating temperature -40 ° to + 85 °, the transmission distance up to 1 km (800 meters 800 meters cable F1.5 test recommended 800 meters plus repeaters). (4) semi-hole pad, on-board module, thin PCB, a thickness of 0.8mm. (5) With RXD, TXD signal indicator to monitor the sending and receiving status. Features: (1) The module takes full consideration of the lightning protection design. The long-distance transmission signal 485 in the field and the grounding of the module are grounded. It can play a very good anti-interference and anti-lightning effect safer; indoor short-distance transmission can not Ground. (2) The standard 2.54 pitch design, easy to secondary development. (3) There is a 120 ohm termination resistor that shorts R0 to enable the termination resistor. (4) support multi-machine communication, a can play a good anti-jamming and lightning effects, more secure; indoor short-distance transmission can not be grounded. (2) The standard 2.54 pitch design, easy to secondary development. (3) There is a 120 ohm termination resistor that shorts R0 to enable the termination resistor. (4) support multi-machine communication, a can play a good anti-jamming and lightning effects, more secure; indoor short-distance transmission can not be grounded.
