This adapter performs a bridge between an USB port and the 1-Wire protocol. It allows users, iButton ASD's and OEM's to replace the legacy COM port adapters with USB, without any changes to the current software.
Applications
- Replacing current RS-232 COM adapters
- Expanding the number of available 1-Wire ports
- Software licensing or asset identification through the built-in DS2401 ID chip
Functional Description
The bridging is performed at driver level; all that is needed is to install the supplied drivers. The driver provides all the necessary operations to communicate with any 1-Wire device through a 1-Wire driver, just like any ordinary RS-232 COM port.
This adapter emulates a
DS9097U serial adapter, providing true-ground interface to an USB port, reading and writing at regular and overdrive speeds, strong pull-up to 5V for Temperature, Crypto and EEPROM 1-Wire devices and user configurable slew rate controlled 1-Wire pull-down and active pull-up.
Application Information
The adapter is plug-and-play. When connected for the first time to any USB port, the setup screen will pop-up. To use the adapter with current applications, all it takes is adjust the settings to use the virtual COM port that is added to the system during setup.
