IN1404 User’s Manual 4
Output
The IN1404 features selectable output resolutions from 640 x 480 up to 1365 x 1024 to match the
optimum or native resolution of virtually any display device. The unit provides a progressive scan
output signal at standard resolutions and refresh rates, ensuring optimal compatibility and
exceptional image quality with a wide range of CRT, LCD, DMD, ILA, D-ILA, and plasma display
devices.
The output refresh rate is also selectable as desired. When the IN1404 is used with LCD or DMD
displays, the 60 Hz output setting is recommended. Higher output refresh rates may be selected for
use on CRT type displays in order to reduce flicker and provide enhanced ergonomics. The chart on
page 22 indicates the available output resolutions and refresh rates.
The IN1404 provides dual outputs to 5 BNC connectors and a 15-Pin HD (VGA) connector. Since both
are active simultaneously, the IN1404 can directly drive two separate display devices. The output
signal format can be set to RGBHV, RGBS or RGsB as required (see page 18).
The stereo audio output provides an unbalanced line level signal (identical to the input signal). This
output can drive any line level compatible audio unit, or a local device such as powered speakers.
Installation
This section offers step-by-step instructions for installing the IN1404 Video Scaler. An application
diagram is provided on page 6.
CAUTION
Read the instructions carefully before initiating the installation procedure. Make sure that
there is no power connected to the IN1404, and that the power button is off.
1. Place/install the IN1404 at the desired location. Make sure that the unit is seated on a flat surface
or is securely installed in a standard 19” equipment rack using the mounting brackets provided
(70-391-01). The IN1404 is exactly 1U high
without the feet. If other equipment will be located in
the space directly below the scaler, the rubber feet on the bottom of the unit must be removed
before mounting it in the equipment rack.
2. Connect the video and computer video sources to the appropriate IN1404 input(s). Any of the
four inputs can accept either a composite video signal or an S-video signal. Inputs 3 and 4 can
also accept component video, progressive component video, RGBHV, RGBS or RGsB signals. See
IN1404 rear panel connectors on page 6 for more details.
•
Composite video sources with BNC output connectors can connected using an 26-383
series single coax cable (available in lengths from 3’ to 300’). Devices with an RCA
output connector can be connected using a BNC to RCA adapter cable.
•
S-video sources may be connected via a 26-316 series S-video cable.
CAUTION
On Inputs 1 and 2, Video input signals must only be connected to either the composite video
or the S-video connector on any one input. DO NOT connect composite video and S-video
signals simultaneously on the same input!
•
Component video sources and progressive component video sources may be connected
to input 3 or input 4 using a BNCM-RCAF RCA to BNC adapter or a 26-210 series
4-BNC cable. Take care that the component video signals are connected to the correct
connectors. For more information on component/progressive component video
connections, see the chart on page 7.
•
RGsB / RGBS / RGBHV video signals from video and computer video sources can be
connected to input 3 or input 4 by using four or five BNC cables or a multi-conductor
RGBHV, RGBS or RGB "snake". The 26-210/26-260 series cables are well suited for this
purpose (see
Cables on page 41). While making connections, take care to insure that the
red output is connected to the red input, green output to the green input, etc.
