Interface Board
1.
Remove all the trim, top-right cover, and bottom covers.
2. Remove the floppy disk drive assembly.
3. Remove the power supply.
4. Remove the Mother board.
5. Set the instrument so its bottom is down on the work surface and the top
panel is facing you.
6. Remove the two jack screws that secure the VGA connector to the bracket
(see Figure 6--16 on page 6--30) and then remove the bracket and set it aside.
7. Refer to Figure 6--17 on page 6--32 and disconnect all cables from the
Interface board. Note the location of each cable so you can reconnect them
properly during reassembly.
8. Remove the six T-15 Torx-drive screws that secure the Interface board to the
chassis.
CAUTION.
Do not remove the screw underneath the power supply bracket next to
the multi-pin connector (See Figure 6--17 on page 6--32). The screw secures an
indexing pin used to align the multi-pin connector to the Acquisition board.
9. Grasp the Interface board (see Figure 6--17) and carefully pull the board up
to disconnect the multi-pin connector underneath the power supply bracket.
Once you have cleared the connector, remove the board from the chassis.
10. When installing the Interface board, set the board in place and align the
multi-pin connector under the power supply bracket using the guide pin.
Gently press the board into place to seat the connector between the Interface
board and the Acquisition board.
11. Complete steps 8 through 1 in reverse order to complete the installation.
Tighten the T-15 Torx-drive screws to 8-in lbs. Tighten the jack screws to
4.0-in lbs.
