Product Description
The ECO422D SD/HD Changeover Unit provides automatic selection of reference
sources. Automatic changeover may occur upon fault detection in any active
source. Automatic transfer ensures uninterrupted signals for critical applications.
The ECO422D is an in-line device without internal buffers. Switching is by
mechanical relay. The ECO422D also provides internal termination for unused
inputs.
NOTE. A source transition can occur if the channel output amplitude is reduced.
This can be caused by over-termination, cable damage, or an accidental short to
ground. A channel’s selected input and its output are directly connected through
an internal relay, therefore the ECO422D detects an output reduction as an
input reduction. This does not apply to the three Option ELSW channels, which
are buffered.
To avoid this problem, work on an output only when the ECO422D is not in
operation. Disconnect the output cable from the ECO422D before working on
the cable, and verify proper termination before reconnecting the cable to the
ECO422D.
Option ELSW provides electronic switching on channels 4, 5, and 6, instead
of the mechanical relays, for faster switching on NTSC or PAL black burst, or
trilevel sync. With Option ELSW the channel 4, 5, and 6 inputs and outputs are
internally terminated. A relay is provided to switch the primary input to the output
in case of power failure.
ECO422D Installation and Safety Instructions 3

Preface
There are 11 channels. Each consists of a Primary Input, a Backup Input, and an
Output. All relays switch in unison upon fault detection in any active channel,
front-panel command, or remote command.
The ECO422D bases error checking on signal amplitude. You can configure each
channel to check for a different type of input. There are six predefined checking
levels (seven levels on channels one through six): no checking, PAL analog black
burst, NTSC analog black burst, high definition trilevel sync, serial digital high
definition and standard definition component video, NTSC serial digital composite
video, and serial digital audio. A fault occurs when the signal is between 2 and
6 dB down from nominal, depending on the predefined level chosen. There are
also two user-defined checking thresholds available.
Separate indicators on the front-panel display faults for both the primary and
backup generator. These indicators remain on until cleared by the operator.
Power Up Delay The ECO422D has a delay between the time power is applied and the time the
ECO422D starts error detection. This delay allows source equipment to become
operational before detection begins. In early units this delay was greater than
four minutes. With the addition of S13 the delay is adjustable, in approximately
30 second increments, from 0 to approximately eight minutes.

Pollution Degree
Description
A measure of the contaminants that could occur in the environment around
and within a product. Typically the internal environment inside a product is
considered to be the same as the external. Products should be used only in the
environment for which they are rated.
Pollution Degree 1. No pollution or only dry, nonconductive pollution occurs.
Products in this category are generally encapsulated, hermetically sealed, or
located in clean rooms.
Pollution Degree 2. Normally only dry, nonconductive pollution occurs.
Occasionally a temporary conductivity that is caused by condensation must
be expected. This location is a typical office/home environment. Temporary
condensation occurs only when the product is out of service.
Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution
that becomes conductive due to condensation. These are sheltered locations
where neither temperature nor humidity is controlled. The area is protected
from direct sunshine, rain, or direct wind.

Front-Panel Controls and Connectors
Front-Panel Controls and Connectors
The followingfigure shows the layout of the ECO422D front-panel controls and
indicators. There are no front-panel connectors. (See Figure 1.)
Figure 1: ECO422D front panel
Sync Source -
Primary/Backup
The LED indicates the source of the current output, whether it is from the primary
or backup input. Press the Sync Source button to manually change the signal
source. (If the ECO422D is in Normal mode, this is only true when the other
input is good or both inputs are bad. (See page 25, User Configuration Switch
(S14-8).) Only one of these LEDs can be on. Primary is the default source when
the instrument is powered on.
Auto Switching - Switch
Fault/Disabled
This switch selects whether the ECO422D will automatically switch to the other
input source whenever it detects a fault (Switch on Fault) or not switch (Disabled).
Only one of these LEDs can be on after the power-on delay. Switch on Fault is the
default setting. During power-on, the DISABLED LED slowly blinks to indicate
that the front panel is disabled and error detection during the power-on delay.
Fault Indicator (Reset) -
Primary/Backup
Either one or both of these LEDs can be on. They indicate that a fault has occurred
on the input. Press the RESET button to clear the fault indicators (turn off the
LEDs) after the fault has been corrected. The fault indicator does not automatically
reset after an error condition improves. At power-on, the LEDs are reset.
Front Panel -
Enabled/Locked Out
This control determines whether or not the operator has access to the other front
panel controls. If it is Enabled, then the user can control the instrument from the
front panel. If it is Locked Out, then the user can only toggle back to Enabled and
no other front-panel controls are available. The ECO422D will automatically
lock out after about 1 minute of inactivity to prevent accidental switching. The
front panel is automatically locked out at power-on (during power-on, both LEDs
are lit).

Rear-Panel Controls and Connectors
Rear-Panel Controls and Connectors
The followingfigure shows the rear-panel layout of the ECO422D. (See Figure 2.)
Figure 2: ECO422D rear panel
Power This instrument is designed to operate from a single-phase power source with one
current-carrying conductor at or near earth-ground (the neutral conductor). Only
the line conductor is fused for over current protection. Mains frequency is 50 or
60 Hz. The operating voltage range is continuous from 100 to 240 VAC ±10%.
WARNING. WARNING. To prevent personal injury, do not connect power to the
ECO422D if the top cover is not installed. Dangerous potentials are present
on the Power Supply board.
Video Signals
(11 Channels)
There are 33 video connectors on the rear panel, arranged into a Primary input,
aB
ackup input, and an Output for each of the 11 channels. A general overview
of each one is below.
Primary. Input from the primary sync generator. It can be PAL black burst, NTSC
black burst, analog trilevel sync, serial digital video, or serial digital audio if
signal checking is desired. There are also two user-defined levels available. If no
signal checking is required, almost any signal can pass through the unit (within
the bandwidth and voltage/current limitations). This should be the same signal
type as its Backup signal pair.
Output. Signal output. It is either from the Primary or the Backup source. How
the ECO422D is configured determines under what conditions the source changes.
ECO422D Installation and Safety Instructions 13

Rear-Panel Controls and Connectors
Backup. Input from the backup sync generator. This should be the same signal
type as its Primary signal pair.
Opt. ELSW. With Opt. ELSW, channels 4, 5, and 6 are designed for use only with
NTSC or PAL black burst, or trilevel sync.
Remote The rear-panel connector is a 9-pin female D-connector, with one pin tied to
ground. (See Figure 3.)
