Description

USB to RS232, USB to RS485, USB to TTL (UART) converter. It has a fully automatic, delay-free transceiver circuit for fast, stable communication. Built-in 3.3V / 5V TTL serial voltage converter, with TTL level selection by switch. 3 status LEDs show power, TXD and RXD. The housing is made of aluminium alloy, which makes it solid and hard-wearing. The USB-B and RS232 connectors are high quality. Thanks to its fast, stable, reliable and safe communication; it is the ideal choice for industrial control equipment and / or applications with demanding communication requirements. It has protection circuits such as power isolation, magnetic isolation, self-resetting fuse, TVS (transient voltage suppressor) and so on.
Technical features
  • USB TO RS232, USB TO RS485, USB TO TTL (UART)
  • Uses the original FT232RL chip: fast, stable and reliable communication, better compatibility
  • Power isolation: provides a stable isolated voltage, no extra power supply needed for the isolated end
  • Magnetic isolation: gives signal isolation, high reliability, interference immunity and low power consumption
  • Built-in TVS (transient voltage suppressor), effectively suppresses surge and transient voltage in the circuit, lightning-proof and anti-static
  • Built-in self-resetting fuse and protection diodes, guarantees stable current / voltage outputs, provides overcurrent / overvoltage protection and improves shock resistance
  • Fully automatic, delay-free transceiver circuit, ensures the USB port communicates with the various interfaces quickly and stably, without interfering with each other
  • Built-in 3.3V / 5V TTL serial voltage converter, TTL level selection by switch
  • Sandblasted and anodised aluminium alloy housing, solid and hard-wearing
  • 3 LEDs to indicate power and transceiver status
  • High-quality USB-B and RS232 connectors
