National Instruments 776572-80 Custom Circuitry Module

Part Number 776572-80 is the identifying part number for the National Instruments SCXI-1180 Custom Circuitry Module. The 776572-80 is a 50-pin cable-extension device used with the National Instruments SCXI product line. This device is generally used to extend signal lines for signals that do not require conditioning from the rear to the front of an SCXI chassis. The device consists of a front panel and a 50-pin cable assembly that can be used in three different ways. 

Initially, the 776572-80 may be utilized as an extender for a SCXI module's rear signal connector. Specifically, the SCXI-1180 can be used to move a module's 50-pin rear signal connector to the front of the SCXI chassis. Likewise, it can also be used as a plug-in board cable extender: with the SCXI-1180 and an SCXI-1340 cable assembly, you can incorporate the signals from a plug-in board, such as a DIO board, into the SCXI chassis system. Lastly, it can also be used as a daisy-chain extender: with the SCXI-1180 and an SCXI-1340, SCXI-1341, or SCXI-1342 cable assembly, you can access signals on the cable between a module and a plug-in board, particularly those signals that the module does not use. 

To install the 776572-80 into a suitable SCXI chassis, first, either the computer that contains the plug-in board is turned off or the board is disconnected from the SCXI chassis. Then, the SCXI chassis is turned off and the module is placed into an empty slot. The cables are then connected as per the required configuration. After this, you can screw the front panel of the custom circuitry module to the top and bottom threaded strips of your SCXI chassis. When this is done, you need to screw the rear filler panel to the threaded strips in the rear of the chassis. Lastly, you check the installation before turning on the SCXI chassis and reconnecting the board to the chassis or the computer.
