Setup Guide — IN3254

This guide provides basic instructions for an

experienced installer to set up and operate the

Extron® IN3254 Distribution Ampliﬁer (DA).

C Installation and service must be performed

by authorized personnel only.

Step 1 — Turn off the DA and input/output devices

Turn the input and output devices off and unplug their power cords. Verify that the DA is

disconnected from the power source before proceeding.

Step 2 — Attach input cables

Connect an RGBHV, RGBS, RGsB, RsGsBs, component video, S-video, or composite video

device to these BNC connectors (c). See ﬁgure 1 for information on how to cable the

BNC connectors.

Step 3 — Attach output cables

Connect up to four RGBHV, RGBS, RGsB, RsGsBs, component video, S-video, high

resolution monochrome video, or composite video output devices, such as projectors or

monitors, to these BNC connectors (d). See ﬁgure 1 for information on how to cable the

BNC connectors.

Step 4 — Power on DA, input/output devices, and check for picture

Plug the external power supply cord into the power connector (a). When power is

applied to the unit, the front and rear panel LEDs (b) light.

Connect the power cords and turn on the input and output devices. The picture should

appear on the video displays.

N The output signal(s) must match the input signal. If the picture does not appear, check

that the BNCs for the output(s) and input are connected with an identical signal.

Step 5 — Adjust video gain and sync level

Use the sync and gain DIP switches (e) to select either high or low video gain and sync

level. Adjust video gain while viewing the displayed image to set the level that provides

the best picture quality.

Step 6 — Mount the DA

If necessary, mount the line driver. Make any cabling

adjustments before mounting the line driver, as the

cables may be inaccessible afterwards.

The DA can be mounted using an optional Extron

2U universal rack shelf (part number 60-032-01) as

follows:

a. Remove the rubber feet if they were previously

installed on the bottom of the unit.

b. Place the DA on one side of the rack shelf. Align

the front of the DA with the front of the shelf and

align the threaded holes on the bottom of the DA

with the holes in the rack shelf.

c. Secure the DA to the rack shelf with the two provided 4-40 x 3/16 inch machine screws.

Insert the screws from the underside of the shelf and securely fasten them through

diagonally opposite corners.

d. Fasten the false front panel (provided with the rack shelf) to the unoccupied side of the

rack (as shown in ﬁgure 2), or install a second half-rack-width device on that side by

repeating steps a through c.

e. Secure the rack shelf to the rack using four 10-32 x 3/4 inch bolts. Insert the bolts through

#10 beveled washers, then through the holes in the mounting brackets.

Troubleshooting

If the image does not appear or is not displayed properly

• Make sure that all of the devices are powered on.

• Make sure that each device is receiving power. The front and rear panel LEDs on the DA

should be lit.

• Check the cabling and make adjustments as needed.

• Check the manuals of the input and output devices or contact Extron to determine if there

are special requirements to output video to the external video port.

If problems persist, contact the Extron S3 Sales and Technical Support Hotline.
