Isolated Dual Channel USB/Serial Adaptor with adjustable signal levels

The USB/Serial Adaptor provides two virtual serial interfaces (UARTs) at a personal computer. The UART signals has TTL levels (2.5 - 5.5V) and therefore a direct communication with microcontrollers is possible. The level can be setup by a switch, either 3.3V, 5V or a variable level (2.5 - 5.5V), determined by the supply voltage of a connected circuit. Both UART interfaces are isolated against the USB connector. Each UART interface provides a data output (TxD), input (RxD) and also a handshake output and input. Usually RTS and CTS are set as handshake lines, but can be changed to DTR and DSR by jumpers inside the device. All connectors are protected against ESD and short circuit.

The device is based on the USB/serial interface circuit FT2232H by Future Technology Ltd. (FTDI). This circuit is connected with "USB High Speed" (480MBit/s) to the PC, therefor low latency times are offered and baud rates up to 12MBaud are possible! FTDI offers very powerful and flexible drivers. They are available for "Microsoft Windows", "Apple MacOS", "Linux" and other operating systems.

Characteristics Overview:

• two UART interfaces, isolated against USB

• adjustable signal levels: 3.3V, 5V or variable, controlled by an input pin (2.5 - 5.5V), convenient selectable with a switch

• each UART channel with a data output (TxD) and input (RxD)

• each UART channel with a handshake output (RTS or DTR) and input (CTS or DSR), selectable by jumper

• baud rates up to 12MBit/s

• all connector pins are protected against short circuit, overvoltage (ESD) and wrong polarity

• drivers for "Microsoft Windows", "Apple MacOS", "Linux" and more

• EEPROM to configure the FT2232H by "FT_Prog" (optional)

• USB 2.0 connector, High-Speed (480MBit/s), also suitable for Full-Speed (12MBit/s)

• 10 pin header connector for the UART signals (0.1" pitch)

• shielded and robust metal casing (alu profile)

• industry quality

• designed and manufactured in the EU/Germany
