4.3.2 Rear Panel

The pinout for the 25-pin System connector is provided later in

The panel cutout size conforms to the 3/8 DIN standard. Panel-
Mounting Jacks (order code AA928) are available that slide into
two slots at the sides of the instrument. Use the following proce-
dure to mount an SC2000 into a panel.

Figure 4-2: Panel Cutout Drawing for SC2000 (not to scale)

• Step 1: In the panel or rack, cut a hole as shown above. The
panel may be up to 1/4" in thickness.
• Step 2: Use an 0.062" Allen wrench to remove two set
screws that hold the Panel-Mounting Jacks to the case. To
do this, insert the wrench into the side slots at the rear. Re-
move the screws completely.
• Step 3: Remove the Panel-Mounting Jacks by sliding them
toward the rear. If the jacks don't slide easily, tap them gently.
• Step 4: Put the instrument through the hole in the panel.
• Step 5: Reinsert the Panel-Mounting Jacks into the slide
slots. Slide them as far toward the panel as possible.
• Step 6: Reinsert the setscrews and tighten them. This will
force the Panel-Mounting Jacks toward the rear side of the
panel, drawing the instrument tightly into place.
