The Multi-Bus Converter is an industrial-grade isolated converter that supports USB/RS232/ TTL to RS232/RS485/TTL, with built-in power supply isolation, digital isolation and protection circuits (TVS diode, resettable fuse and protection diodes).
It is easy to use and suitable for industrial control equipment and/or applications with high communication requirements.
The converter has LED indicators for checking power connections and RX/TX signal status. The robust aluminium alloy body makes this suitable for industrial and high-traffic areas and includes flanges for wall or surface mounting.
Data can be transmitted/converted between each 'group' of connections (A and B) as per the diagrams below. Terminals in the same group cannot communicate with each other and cannot send data at the same time (however concurrent receiving of data is possible). An onboard switch allows you to quickly switch between 3.3V and 5V TTL levels of the group B terminals.
A USB-B cable is included in the package for connecting to your host computer. Windows 11/10/8.1/8/7/XP is officially supported.
Features
- 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 jam proof, low power consumption
- Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning proof & 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
