MODULE CARD INSTALLATION (cont.)
Most circuit board modules have several adjustments
which
are
carefully factory set with precision instruments for optimum
performance. WARNING: DO NOT adjust any controls, some
controls
when
mis-adjusted produce little change under normal
operating conditions,
but can seriously
reduce the ability of the unit to function correctly
under
other conditions which may be encountered.
HOW TO CABLE THE UNIT
The unit has two independent channels. All input, output, and
controls are marked with the suffix “A” or “B” depending on the channel
you are working with. This manual will describe the
connection
and
operation of the “A” channel. The “B” channel is connected
and
operated exactly the same as the “A” channel.
Connect a BNC cable from your source video to the "VIDEO
INPUT
A" of the ACE472 PC Card. The "VIDEO INPUT" is
internally terminated
by a precision 75 Ohm termination to
match standard video cable. The
ACE472-UTP connects to a CAT-5 twisted pair cable, and has a
105 Ohm Termination on screw terminals.
Next connect a BNC cable from the PRIMARY VIDEO OUTPUT
(A1)connector on the ACE472 to the equipment you wish to have controlled
video supplied to. There are two separate video outputs on each channel
so that two video circuits may be driven at once with the same video
signal. The "VIDEO OUTPUTS" of the ACE472 have a 75 Ohm output impedance
to match standard video cable. Be sure the equipment being driven is
properly terminated with a precision 75 Ohm termination to insure
correct video level. Failure to terminate the output cables with an
accurate 75 Ohm termination is the leading cause of incorrect video
output voltages.
POWER SUPPLY INSTALLATION
Power for the ACE472 is supplied by the RMS-400 Mainframe. It
supplies the card with +/- 12 VDC to power the card.
SET-UP OF THE UNIT
There are no adjustments or controls that have to be
set at
installation. The ACE472 will now automatically control all video that
passes through it and maintain the proper levels as indicated in the
specifications.
OPERATION
The ACE472 is a base-band video processor
that
stabilizes video
levels, clamps out low frequency
interference, and
automatically
corrects Luminance and Chrominance levels on any length of cable
up to 5000 feet long. The ACE472 will control the following parameters
at the output:
