Installing the CB-50

Notice Although the connectors are keyed, it is possible to force the connectors into the header the wrong way. You must be absolutely certain that the connectors are correctly aligned. Failure to do so could cause signals to be connected to the wrong pins, which could damage the data acquisition board and the computer. NI is not liable for damage resulting from such connections.

Complete the following steps to install the CB-50:

  1. Plug either end of the ribbon cable into the 50-pin rear panel connector on the board, aligning the tabls and arrows as shown.

  2. Firmly push in the connector for proper contact.
  3. Insert the ejector ears into the connector block as shown.

  4. If you plan to mount your connector block for stability, either flush mount or rail mount the CB-50 as follows; if you do not want to mount the connector block, proceed to step 5.
    Mount TypeProcedure
    Flush mounting
    1. Insert the flush-mount brackets into the connector block base as shown.

    2. Place the connector block where you want to mount it and screw it into place.
    Rail mounting
    1. Pry off the right and left ends of the connector block with a screwdriver as shown.

    2. Insert the rail-mount bracket into the slots on the bottom of the connector block as shown.

    3. Replace the end of the connector block and push very firmly until it snaps into place; repeat for the other side, making sure that both rail-mount brackets are facing the same direction.
    4. Slide the rail-mount brackets of the connector block onto your rails.
  5. Plug the free end of the ribbon cable into the connector block, aligning the tabs and arrows as shown.

  6. Firmly push in the connector until the ejector ears on the block header connector snap into position.
    The numbers on the connector block correspond to the pin numbers of the rear panel I/O connector on the board.
