Setup Guide ­— DAV/DAS101CM Series
This card provides basic instructions for an experienced
installer to set up and operate the Extron DAV101CM VGA
Series Line Drivers and DAS101CM Series Audio Buffers.
Installation
C Installation and service must be performed by
authorized personnel only. These units must be installed in accordance with national
and local electrical codes.
To install the DAV101CM and DAS101CM modules, follow these steps:
Step 1 — Prepare wall box and cables
Install an electrical box or wall bracket (if applicable) and cables. Use cable clamps to hold
cables in place for strain relief. Trim back or insulate exposed cable shields with heat shrink to
prevent short circuits. If needed, see chapter two of the DAV101CM Series, DAS101CM Series
User’s Manual for diagrams.
Step 2 — Cable rear panels
Attach cables to the rear panel. Ensure that power and
output cables have been fed through the wall box/
furniture and out the front of the faceplate, frame, or
panel. Connect modules to each other (if applicable) and
to the power supply, but do not apply power yet. Connect
output cables. See the diagrams here and in chapter two
of the DAV101CM Series, DAS101CM Series User’s Manual.

C The pin assignments of the DAS’s power input and power loop-through ports are
different from those of the DAV’s power input.
Double-check your work against the wiring diagrams. Power wires must be attached
to the correct terminals on each connector or these products can be damaged.
C Always use a power supply supplied and or specified by Extron. Use of an unauthorized
power supply voids all regulatory compliance certification and may cause damage to
the supply and the end product. Unless otherwise stated, the AC/DC adapters are not
suitable for use in air handling spaces or in wall cavities. The installation must always
be in accordance with the applicable provisions of National Electrical Code ANSI/
(Continued on reverse side)
Setup Guide ­— DAV101CM, DAS101CM Series (cont’d)
NFPA 70, article 75 and the Canadian Electrical Code part 1, section 16. The power
supply shall not be permanently fixed to building structure or similar structure.
Step 3 — Attach modules to optional mounting frame
For wall, furniture or rack installations, attach the module(s) to a CPM Series mini architectural
adapter plate (MAAP) frame or to a rack-mountable frame.
Step 4 — Cable inputs
Attach cables from the source device(s) to the front panel input connector(s).
• Cable a computer to the DAV’s 15-pin HD connector, which provides ID bit termination on
pins 4 and 11.
• Connect an unbalanced, line level stereo audio source to the DAS. Audio connectors can be
wired as shown below.

Step 5 — Test the system
Verify correct cabling and connector wiring and test the system:
a. Power on all the devices and monitor the audio/video output. Each
DAV module’s Power LED is lit while the unit receives power.
b. If needed, power off the devices, disconnect the modules’ power supply,
correct cabling or wiring errors, then restore power.
Peaking
Step 6 — Set the sharpness and peaking
For a DAV101CM, set the peaking control using a small screwdriver,
as shown at right. While viewing the output image, rotate this
potentiometer to select the setting that gives the clearest pictures.

Step 7 — Disconnect power
Disconnect power from the module(s) and other devices.
Step 8 — Mount the modules
• For wall or furniture mounting, mount the modular connector frame and module(s) to the
wall or furniture.
• For device mounting, mount the module(s) to the device’s faceplate.
• For rack mounting, mount the rack-mountable frame to the equipment rack.
• For all installations, place the connector plate onto or against the mounting surface and
secure it to wall, furniture, device, or rack with the provided screws or bolts. Be careful not
to damage the cables.
Step 9 — Connect power
Restore power to the devices. You have completed the installation.
