The Chameleon Ethernet Network Interface Module Type 2 (NIM-2) with integrated 6-Port Switch offers 10/100 Mbps copper and fiber optic communications. The heart of the device is a programmable 400MHz PowerPC processor core and Linux compatible operating system with 128MB of DDR RAM and 16MB FLASH. This processing power makes the NIM-2 a capable remote I/O controller, server, and general purpose communications platform. Multiple NIMs (additional NIM-2’s and/or other networking module types) can be combined to form a network gateway, message router, or bridge.

The NIM-2 provides a variety of Internet applications, protocols, and services including support for common industrial protocols such as EtherNet/IP Server, EtherNet/IP Client, Modbus TCP/IP Server, Modbus TCP/IP Client, TCP Messaging, UDP (Unicast/Multicast) Messaging, and SNMP.

The Fairmount Automation Network Data Access (FANDA) SDK provides MS Windows C++ software developers a mechanism to interface with the NIM-2 through an encrypted connection. This connection allows remote devices to securely login, retrieve an XML network definition file that describes what data can be read/written to (both through the shell and multicasts), and allows that data to be read/written in the Chameleon. The interface also provides remote maintenance capabilities. The FANDA SDK is available in the form of a DLL and associated .h file.

Ordering options permit up-to four LC fiber optic ports or up-to two ST fiber optic ports (remaining ports are copper). Each copper port is equipped with 1500 volts isolation and auto-sensing 10/100 Mbps connections. Auto-MDI is also included to provide automatic compensation for crossover wiring errors during installation (i.e. connections are independent of crossover or non-crossover cabling). In addition, two copper ports can be ordered with automatic loop failover relays. This feature automatically connects two ports together (for example the input and output ports on a ring or bus) when power is lost or an on-board failure occurs thereby preventing a network break.

Using Fairmount Automation’s intuitive and easy-to-use graphical programming package (Design Pad) you can develop sophisticated remote I/O control and communications schemes for the NIM-2 in a matter of hours—even without any prior programming experience. Programming the device entails “drawing” a desired control scheme using a vast array of configurable function blocks. These function blocks are wired together to indicate the signal flows from device inputs to device outputs. Design Pad also features network configuration tools for all the supported protocols and applications. Once complete, configuration programs are downloaded to the unit via a wireless IR interface.

Each NIM-2 unit provides 6 three-color LEDs for each port to provide status, activity, and speed indication. The module also has a three-color status LED.

As with all Chameleon modules, the NIM-2 offers unequaled ruggedness. It is specifically designed for sustained operation in severe environments, including those characterized by extreme shock, vibration, electro-magnetic interference, temperature, and humidity. Its fully-sealed enclosure (sealing end-caps not pictured) ensures long-lasting operation in the grimiest settings. In fact, Chameleon modules can operate fully submerged.
