Special Features

  • 1, all chips we guarantee that the new original imported industrial-grade chips, ultra-long-distance transmission.
  • 2, with RXD, TXD, power three LED indicators, serial input protection; 3, the chip has a limit swing rate driver, minimise EMI, and reduce the signal reflection caused by improper terminal matching cable, so that the error-free signal transmission rate up to 500Kbps.
  • 3, with 1/4 unit load receiver input impedance, support for multi-computer communication, allowing connection to a bus of up to 128 devices.
  • 4、Industrial grade chip operating temperature can reach -40C to +85C
  • 5, the module can be hot swappable, there will be no other 485 chip hot plugging the phenomenon of signal bolting.
  • 6, with 120Q termination resistance (line length of more than 200 metres, more stable, reduce the BER).
  • 7, the use of transient suppression TVS 600W diode, over-voltage protection performance is better: 9, the use of 10Q current protection resistor, chip design to improve the integrity of the 485 signal; 10, RS485, TTL signals, all single-sided routing, to ensure signal quality, improve signal integrity; 11, a large area of copper paving, to prevent the hot plugging phenomenon of copper.
  • 8, large-area copper, to prevent signal interference.
  • 9, supports a variety of baud rate: 300/600/1200/2400/4800/9600/19200/38400/57600/115200/230400/460800/921600, etc.:.

Description

Wiring Description 232 end:R and T:RS232 bus receive and transmit, and other RS232 module connection needs to cross and, that is, RX connected to TX. G is the ground of 232 terminal, connect to external negative pole. V:Positive terminal of module's power supply, connect to the positive terminal of external power supply. 485 terminal: A and B: RS485 bus DATA + (A) and DATA - (B), 485 need to A to A, B to B; G:RS485 reference ground, generally can be left unconnected.
