M MP00202

The device is built on the DS2480B converter controller from Dallas-Maxim (RS232 to 1-Wire converter). The FT232RL chip from FTDI is used for conversion from the RS232 standard to USB.

After installing the FT232RL chip drivers, a virtual serial port appears on the computer, enabling access to the 1-Wire bus.

From the software perspective, the device is compatible with converters based on the DS2480B chip, such as original DS9097 interfaces from MAXIM-DALLAS, with the only difference being that the interface is connected via USB instead of the RS232 serial port.

The device includes a chip with a unique serial number (DS2401), typically used for software protection purposes. In this case, the device also acts as a hardware key for the software.

Features:

• USB 2.0 interface

• Reads all 1-Wire and iButton devices

• Writes to all devices except EPROM memory

• Powered via USB

• Equipped with a DS9503 protection circuit for the 1-Wire bus

• Extensive free software and source codes available

• Compatible with free software One Wire Viewer, TMEX from MAXIM-DALLAS, as well as other compatible software such as LogTemp, Lampomittari, etc.

• 1-Wire output via terminal strip

• 5V DC power output (from the USB port) for powering external devices with a maximum current of 500mA

• LEDs indicating data reception and transmission

Typical Applications:

• Distributed measurement systems

• Control and measurement systems

• Data loggers (e.g., for temperature, voltage, etc.)

• Internet-based control and measurement systems

• Access control and authorization systems, software protection, etc.
