Installation and Cabling
The Extender must be cabled, optional MAAPs must be installed and cabled, and
both the Extender and MAAPs must be tested before attaching mounting plates to
the enclosure and mounting the assembly into the floor box.
1.
Unpack the Extender AKM MAAP and any optional MAAPs. Save all the
screws—you will need them later.
•
Each faceplate assembly comes with four #6-32 x 1/4" to 3/8" long
Phillips pan head screws.
•
Each MAAP faceplate or module requires at least two socket-head cap
screws (#4-40 x 1/4") for securing the MAAP to a faceplate. Six of these
screws are included with the Extender AKM MAAP along with a small
Allen (hex socket) wrench. The hex nuts for these
machine screws are built into the Extender AKM
MAAP’s faceplate.
2.
Route the cables up out of the Ackermann floor box and through the opening
in the upper mounting plate.
3.
Connect audio output and power cables to the Extender’s direct insertion
captive screw connectors. See the illustrations below, and refer to the
Extender Series User’s Manual (part #68-552-01, available at www.extron.com) .

CAUTION
For audio, connect the sleeve to ground (Gnd). Connecting the sleeve to a
negative (-) terminal will damage the audio output circuits.
CAUTION
Use a 9 VDC to 18 VDC power supply only. Polarity is not important.
For best results and to reduce the risk of short circuits, trim just 0.2"
(5 mm) of the jacket from the wires. Do not tin the wires.
4.
Loosely attach the upper mounting plate to the lower mounting plate and the
nut bar using the two provided Phillips pan head screws as shown below.

5.
Set the Extender’s gain switch, which will be inaccessible after installation.
The gain switch is located at the rear of the Extender, between the two circuit
boards. Slide this switch to select the level of
video gain that yields the sharpest picture. Refer
to the Extender Series User’s Manual (part number
68-552-01, available at www.extron.com).
