Removal and Installation Procedures
TDS5000B Series Service Manual
6--45
1. Locate module to be removed: Locate the PC interface board in the locator
diagram Internal Modules, Figure 6--6, on page 6--19. Note the location of
cables and cable connectors see Figure 6--16 on page 6-- 32.
CAUTION. Before installing the PC interface board, fully install the acquisition
board. Doing this helps ensure correct alignment of the 125-pin connector
between the acquisition board and the PC interface board.
Additional modules to be removed:
H Trim (all)
H Right-side cover
H Hard drive assembly
H Floppy disk drive
H CDRW drive assembly
H Power supply
H Motherboard assembly
2. Orient the oscilloscope: Set the oscilloscope so the bottom is down on the
work surface and the top panel is facing you.
3. Remove the PC interface board: See Figure 6--24 on page 6--46.
a. Disconnect the two cables from the PC interface board.
b. Remove the six T-15 Torxdrive screws that secure the PC interface board
to the chassis.
CAUTION. Do not remove the screw next to J1800 (See Figure 6 --24 on page
6--46). The screw secures an indexing pin used to align the J1800 connectors
together.
c. Grasp the PC interface board near J1800 (see Figure 6--24) and carefully
pull the board up to disconnect J1800. Once you have cleared the
connector, remove the board from the chassis.
4. Reinstallation:
a. When installing the PC interface board, set the board in place and align
the J1800 halves using the guide pin. Gently press the board into place to
seat the connector between the PC interface board and the acquisition
board.
