Precautions
Important Safety Warnings
[Installation/Operation]
Do not install or operate the module under high temperature, high humidity, dusty,
or high-vibration conditions. Installing the unit in conditions other than those
specified may cause malfunction, fire, or electric shock hazards.
[Transportation]
Caution
Handle with care to avoid impact shock during transit, which may cause
malfunction. When you need to transport the unit, use the original or suitable
alternative packing material.
[Internal Setting Change]
Caution
Turn the power off and disconnect the power cord prior to changing internal settings.
Changing internal settings while the unit is powered on should only be attempted by
qualified personnel.
Stop
Do not touch any parts / circuitrywith a high heat factor. Doing so is hazardous and
may cause burns.
[Potential Hazards]
Caution
If the power does not turn on, or abnormal odors or noises are noticed coming from
the unit, immediately turn the power off and disconnect the power cord to avoid
potentially hazardous conditions. Immediately contact your supplier.
[Consumables]
Caution
Consumable items that are used in the unit must be periodically replaced. For
further details on which parts are consumables and when they should be replaced,
refer to the specifications at the end of the Operation Manual. The service life of
these items vary greatly depending on the environment in which they are used.
Such items should be replaced at an early date. For details on replacing
consumable items, contact your dealer.

1. Features Overview
1-1. Overview
The USF-1040VEA is an Analog Video Equalizing Distribution Amplifier that can distribute 1
analog video input signal to 4 output signals. The USF-1100VEA is an Analog Video Equalizing
Distribution Amplifier that can distribute 1 analog video input signal to 10 output signals. It
supports composite and HD/SD analog component signals.
Installing a USF-VEAIF network interface into an USF-1040VEA/1100VEA allows web-based
monitoring and control of the USF-1040VEA/1100VEA over the network. It also allows SNMP
monitoring.
1-2. Features
Installs into USF frames
Video Gain adjustment
Input cable compensation (up to 300 m when using 5C-2V equivalent cables)
Input signal detecion
Input signal loop through
Video signal couplingclamp setting
Analog video signal distribution, as well as tri-level sync signal distribution
USF-VEAIF enables monitoring and setting via PC web browser through USF frame.
(USF-212S only)

HD
Used to input HD analog component or
tri-level sync signal.
(*1) Set two switches to the same setting.
(*2) When used as CLAMP ON, some signals are not applicable due to video format. Refer to
Sec. 9-1. “Specifications” for details.
DC fluctuation of analog output can be suppressed using AC coupling/CLAMP ON for the
input signal with large DC-voltage fluctuation.
(*3) Set the SW3 and SW4 to LOCAL when the USF-VEAIF option is not installed.
Installing a USF-VEAIF enables USF-1040VEA/1100VEA status displays. Set both SW3
and SW4 to REMOTE to set GAIN and COMPENSATION through Web GUI. Refer to Sec.
