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 as simple as the serial port!
Standard DB9 interface and 5.08mm plug-in terminals, smooth plugging and unplugging, sturdy and reliable, using 5V power supply, the module needs to be connected to the power supply voltage at the 485 end when working.
Adopt large package components, more stable and reliable, with independent power supply isolation and signal isolation circuit, to protect the internal module power supply stability, increase the stability of signal transmission.
The 232 terminal is equipped with overcurrent protection and surge protection. Ensure stable output of current and voltage, strong shock resistance; RS485 terminal with overcurrent protection, surge protection, lightning gas discharge protection circuit.
120R terminal resistor pad is reserved on the board, which can increase the stability of signal transmission and reduce interference.
Baud rate support range: up to 2Mbps
On-board two LED indicators, used to indicate the circuit signal transceiver status
232 terminal indicator: 232 terminal receive data, green light on
485 terminal indicator: 485 terminal receive data, green light on
Aluminum alloy shell, oxidized and frosted treatment, precise opening, solid and durable, exquisite craftsmanship
