⚫ Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage
and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
⚫ Onboard self-recovery fuse and protection diodes, ensures the current/voltage
stable outputs, provides over-current/over-voltage proof, improves shock
resistance
⚫ Fully automatic transceiver circuit with no delay, ensures the USB port
communicates with different interfaces fastly and stably, without interfering each
other
⚫ Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch
⚫ Aluminium alloy enclosure with sand blasting and anodic oxidation, CNC process
opening, solid and durable
⚫ 3 LEDs for indicating the power and transceiver status
⚫ High quality USB-B and RS232 connectors, smoothly plug/pul
