GE / IP FANUC Series 90/30 In Stock
The IC660ELB912 is a µGENI Network Interface Board from GE Fanuc. It is designed to be a daughterboard in a user’s microprocessor system. Users can interface the µGENI and the motherboard in any CPU-type device capable of reading and writing to the general-purpose shared RAM on the µGENI. This device is known as the host.
Although the RAM interface is optimized for the IBM personal–computer bus, it is easy to adapt to various other CPU types. As it handles all data transfers between the host and the Genius I/O bus, the µGENI effectively frees up the host. This allows the host to control remote I/O. It does this by using the features of the Genius I/O, such as high reliability and noise immunity. Furthermore, the host can use the communication features of the Genius LAN to communicate with other hosts.
In a sense, the µGENI is a general-purpose controller, maintaining initialization tasks and managing faults for over 30 other bus devices. Each device controls an I/O and the µGENI keeps updated images of each one. It is also capable of communicating with other controllers through the use of Global Data, datagrams and Directed Control Data messages.
The µGENI has a range of intricate components on its single-printed circuit board.
It uses a 6303-serial interface microprocessor to write messages to the MIT chip. This chip manages the hardware interface to the bus and provides support functions. For example, it handles error checking, LED drivers and a timer function. A transmit/receive circuit works closely with the MIT and bus transmit and receive signals.
The µGENI uses dual port RAM to exchange data. This is done between the 6303-microprocessor and a manager microprocessor - 64180. As the two processors run two separate systems, the dual port RAM ensures they both have equal access. This is controlled by a GAL, delivering memory to either processor on a byte-by-byte basis. The 64180 also has a separate 8Kb of RAM for its exclusive use.
The user should mount the µGENI to the motherboard using spacers. This is done by putting screws, standoffs or plastic PCB supports in the four corner holes of the motherboard. Do not use any adhesive product on the board.
It is important that the µGENI board is not mounted in a way that obstructs airflow across the board. Users should take care not to mount it within 1/8 inch of any other board or component on the motherboard.
The µGENI board needs a 5V DC source to operate logic power.

The final letter in the part number (ex. IC660ELB912K) indicates the revision. Revision K or later use the newer style electronic housing and therefore needs the newer style plastic door and may indicate some compatibility issues with the terminal strip.
