• 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. 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.Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stably, without interfering each other.High quality USB-B and RS232 connectors, smoothly plug/pull.
