[USB-046] USB to Serial/MPSS Converter HuMANDATA LTD.
[USB-046] USB to Serial/MPSS Converter
5KVC high-voltage isolation
Independent control of Serial / MPSSE
Overview
USB-046 is a USB to Serial/MPSS converter that enables independent control of two serial signals via a USB connection. The USB and serial signal interfaces are electrically isolated from each other.
The onboard FTDI FT2232H chip can be configured to use Channel A as a Serial (UART) interface and Channel B as an MPSSE (Multi-Protocol Synchronous Serial Engine) interface. The MPSSE enables communication by emulating serial protocols such as I2C, SPI, and JTAG. The converter provides an isolated power supply, selectable between 3.3 V and 5 V via a switch.
* Second and subsequent images are CG models
Features
- Control via virtual COM port over USB
- Independent control of Serial / MPSSE
- 5000 VDC bus isolation
The USB and serial signal interfaces are electrically isolated from each other. - Isolated 3.3 V / 5 V power supply, selectable by switch
- No external power supply is required
USB-046 is powered through a USB port (Bus-powered) - ESD and surge protection
- Housing material: Plastic
- DIN rail, magnet, and screw mountable (Attachment is required)
- Includes a USB cable (1.8m)
- Wiring harness with connector housing (approx. 200 mm)
- Free from the 10 RoHS-restricted substances.
