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.
