Using the original SP3232, SP3485, high-speed communication is stable, reliable, good compatibility, the realization of the 232 signal and RS485 signal transfer, no need to “receive - send” control, the use of this module with your operation of the serial port is as simple!
Adopt 5.0mm screw type terminal, smooth insertion and extraction, solid and reliable, working voltage: 5.0V, the module needs to be connected to the power supply voltage at the 232 end when working.
With independent DC-DC power isolation and digital isolation chip.
The 232 terminal is equipped with over-current protection and electrostatic protection. Ensure stable output of current and voltage, and strong shock resistance.
RS485 terminal with overcurrent protection, surge protection, lightning gas discharge protection circuitry
On-board 120R terminal resistor selection dip switch, can increase the stability of signal transmission
Baud rate support range: up to 2Mbps (experimental environment)
On-board three LED indicators to indicate the circuit signal transceiver status
PWR light: red, power indicator
TXD light: green, 232 data transmission indicator, data flow: RS485->232
RXD light: blue, 232 data receiving indicator, data flow: 232->RS485
Adopting large encapsulated components, more stable and reliable, rail-type ABS environmentally friendly shell, compact size, easy to install, cost-effective beauty.
