[Chip program] using industrial-grade chip FT232RL, SP3485, SP3232 chipset, good compatibility, to meet the USB TTL 232 422 485 interfaces directly to each other to transfer the communication, 422 interfaces including 485 interfaces ^^ [Circuit Protection] USB terminal contains electrostatic ESD protection circuit, TTL terminal with overcurrent protection, surge protection, 232/422/485 terminal with overcurrent protection, surge protection, power supply isolation, magnetic coupling isolation and so on. ^^ [Interface Optimization] Adopt USB-B interface and 5.08 mm standard terminal block, 5V power supply, TTL signal terminal output level is 5V, 485/422 automatic flow control, TTL/232 with flow control pin.
^^ [Indicator Optimization] On-board five LED indicators, used to indicate the circuit signal sending and receiving status, the indicator corresponds to the status of the four interface signals and module power supply. ^^ [Optimized for use] Aluminum alloy shell, oxidation frosted treatment, with mounting holes, long-distance transmission 422/485 end with lightning gas discharge protection circuit, baud
rate support range: TTL
(UART): 2M bps; RS 232: 256 K bps; RS422/RS 485: 1 M bps
