Overview:The USB177X is a gateway between a PC and networks such as DeviceNettm, CANopen, or other CAN based networks. The unit supports USB or RS232 connections to the PC.

The firmware for the ETH177X is stored in downloadable flash. This allows field updates and optional firmware to be loaded and executed. The unit comes with generic CAN firmware installed (USB1770). This firmware supports both CAN 2A and CAN 2B frame formats and allows higher level protocols to be implemented on the PC. The soft API libraries are included for CANopen and DeviceNet. These libraries can be used in programs created by the user in such languages as Visual C, Visual Basic, and C++ Builder. Other firmware can be purchased from INC such as a DeviceNet Master or CANopen Master.

The unit has a USB connection and a DB9 connector for the RS232 connection. The CAN Network connector is available in a standard low cost 5 pin Combicon connector with screw flanges, or an optional 5 pin sealed micro connector. The Combicon connector allows the use of lower cost cabling, and also allows the use of a dual row Combicon plug to facilitate the daisy chaining of modules in the network. Options include a battery backed real time clock that allows the unit to timestamp all incoming CAN messages, and a connector that supports SD/MMC Cards. SD cards up to 2GB are supported that can be used to log CAN data for data analysis or troubleshooting.

Applications: Configuration Tools, Diagnostic Tools, Data Logging, Soft PLCs, etc.
