instrument specification except for those listed in Environmental Requirements
on page 8. Instruments mounted using methods other than those described in
these instructions may not meet their warranted requirements.
See Specifications in the user or service manual that applies to your instrument
model for tables of the warranted characteristics.
Cooling air enters from the bottom-front and right sides as shown in Figure 3.

Installation Instructions
12 TLA7012 Portable Logic Analyzer Rackmount Kit Instructions
WARNING. To prevent the rackmounted instrument from tipping forward onto the
operator, install the instrument so that the operator will be able to access all of
its rear-panel connectors without pushing down on the instrument.
Verify that the rack does not become unstable with the instrument fully extended.
Do not leave the instrument extended when finished accessing the rear panel.
Assemble Shelf
Begin the installation procedure by attaching the brackets to the track assembly:
1. Remove the mounting screw that is attached to each track. (See Figure 5).
2. Mount one bracket to the front of each track assembly using two 8-32
flathead screws for each bracket. You must slide the rail within the track
assembly to gain access to the mounting screws and holes. See the latch
detail in Figure 6 on page 13).

3. Next, use two 8-32 locking-nut washer assemblies to secure the track onto
the shelf assembly, applying 28 inch-lbs of torque. (You must move the rail
within the track to gain access to the rearward mounting hole).
Refer to Figure 6 to help you attach the tracks to the shelf.

Instrument Rack Preparation
This section describes mounting the rackmount parts to the instrument rack.
1. Remove the right-side panel of the instrument rack.
2. Select two 0.5 inch-spaced holes that have at least 14 inches of clearance
above, on all four rails of the rack. See Figure 7.

3. Select the mounting method according to rack type:
HTo mount the brackets with their rear flanges outside of the rear rails,
use the mounting method A shown in Figure 8 when doing
substep 4. Add a bar nut to the installation only if the rails have
untapped holes.
HTo mount with the rear flanges inside of rails, use the mounting
method B outlined in Figure 8. This mounting method assumes
untapped holes.
Mounting Method A Mounting Method B
Left-rear rail
Use two flat-head screws if the cabinet rails have
countersunk mounting holes; otherwise use two
pan-head screws
Use a bar nut if front rails
are not tapped

4. Using the method and hardware determined from step 3, secure the brackets
to the rear rails. The screws should be fully, but lightly, seated so mounting
can be adjusted later.

5. Mount the cosmetic trim on the front, using two 10-32 screws each. See
item 2 in Figure 10. (This helps to guide you where to locate the shelf during
shelf installation).
Equipment Required: One screwdriver handle (Item 1), one number two Pozidriv
tip (Item 2), and one torque driver (Item 5).
NOTE. The rack hardware kit contains hardware for mounting the instrument in
several configurations. Not all of the hardware in the kit will be needed.
A standard equipment rack has rails with universal hole spacing. If you use a
rack with other than universal hole spacing, you may have to drill additional
mounting holes in the rack.
Procedure:
1. Grab the shelf/track assembly and slide the tracks into the brackets on the
rear rails of the instrument rack.
2. Align the front of the shelf to the bottom of the cosmetic trim on the front of
the instrument rack.

3. Install two 10-32, P2 screws through the front brackets to the rack on each
side of the shelf front.
4. Install two 8-32 screws through the shelf tracks to the rear brackets. Attach
the screws with the 8-32 lock nuts included in the kit.
5. Tighten all of the screws and check that the shelf slides in and out easily.
Loosen and adjust, if necessary.
This completes the installation of the shelf/track assembly into the rack. Next,
perform the Attach Brackets to the Instrument procedure.
