Overview

The USB/RS232/RS485/TTL Converter is an industrial grade isolated converter that supports USB / RS232 / TTL to RS232 / 485 / TTL, with built-in power supply isolation,
digital isolation, and protection circuits like TVS diode. It is easy to use and suitable for industrial control equipments and/or applications with high communication requirement.

Adopts original FT232RL for USB communication, fast communicating, stable and reliable, better compatibility
Onboard over-voltage, over-current protection circuits (there's no protection between the two power supplies of the host terminal)
Onboard unibody power supply isolation, providing stable isolated voltage, no extra power supply required for the isolated terminal
Onboard unibody digital isolation, for isolating the signal, reliable and jamproof, low power consumption
Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance
Onboard TTL serial port 3.3V and 5V voltage level switch, allows the user to select TTL level of the Group B terminal
Aluminium alloy enclosure with oxidation dull-polish surface, solid and durable

Package include

1. Multibus Converter x1
2. USB cable (~1.2m) x1
