Rack Mounting
The DMP128 is delivered with rack mounting brackets attached. For rack mounting,
do not install the rubber feet. Use the rack ears to mount the DMP128 in a standard
equipment rack. The DMP128 can be mounted on a 19"Universal 1U or Basic rack shelf
(Extron RSU 129, part #60–190-01; or ExtronRSB129, part #60-604-02).
To rack mount the DMP128 on a rack shelf:
1. If rubber feet are installed on the bottom of the DMP128, remove them.
2. Mount the DMP128 on the rack shelf, using two 4-40 x 3/16 inch screws in opposite
(diagonal) corners to secure the unit to the shelf. In a standard equipment rack, mount
the DMP128 using the installed rack mounting brackets.

Table or Wall Mounting
The table or wall mounting brackets extend approximately 1/4 inch (6.4 mm) above the
top surface of the enclosure. This design allows for an air space between the enclosure
and the surface to which it is mounted.
Table or wall mount the DMP128 as follows:
1. Remove the rack mounting brackets and attach the MBU 149 brackets in their place.
2. Hold the unit with the attached brackets against the underside of the table or other
furniture, or against the wall. Mark the location of the screw holes of the bracket on
the mounting surface.
3. Drill 3/32 inch (2 mm) diameter pilot holes, 1/4 inch (6.4 mm) deep in the mounting
surface at the marked screw locations.
4. Insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting
surface until just less than 1/4 inch of the screw’s head protrudes.
5. Align the mounting screws with the slots in the brackets and place the unit against the
surface, with the screws through the bracket slots.
6. Slide the unit slightly forward or back, then tighten all four screws to secure it in place.
