Features ultra-stable, reliable and compatible high-speed communication The on-board integrated power isolation can provide stable isolation voltage, and the isolation end does not need additional power supply; On board integrated digital isolation, signal isolation, high reliability, strongly interference-free and low power consumption On board TVStransient voltage suppression tube can effectively suppress the surge voltage and transient peak voltage in the circuit, and avoid static electricity; Board mounted self recovery fuse and protective diode can ensure stable output of current and voltage, avoid over-voltage, and improve impact resistance On board automatic transceiver conversion circuit ensures fast and stable communication between USB terminal and different interfaces without mutual interference; On board TTL serial port 3.3V and 5V level conversion circuit, users can switch TTL communication level through switches Aluminum alloy shell, oxidation and frosting treatment, CNC numerical control opening, solid and durable, and exquisite workmanship;
There are 3 LED indicators outside for convenient viewing of power supply and signal receiving and transmitting status; High quality USB-B and RS232 interface materials, smooth plugging, firm and reliable.
