Digital board removal
Perform the following steps to remove the digital board. This procedure assumes that the
analog board assembly is already removed.
1. Remove the IEEE-488, digital I/O, and RS-232 fasteners.
The IEEE-488, digital I/O, and RS-232 connectors each have two nuts that secure the
con
nectors to the rear panel. Remove these nuts.
2. Remove the POWER switch rod.
At the switch, place the edge of a flat-blade screwdriver in the notch on the pushrod.
Gent
ly twist the screwdriver while pulling the rod from the shaft.
3. Unplug cables:
• Unplug the display board ribbon cables.
• Unplug the cables going to the power supply.
• Unplug the rear panel power module cable.
4. Remove digital board.
Slide the digital board forward until it is free of the guide pins, then remove the board.
During re-assembly, replace the board, and start the IEEE-488, digital I/O, and RS-232
connector nuts and the mounting screw. Tighten all the fasteners once they are all in
place and the board is correctly aligned.
