NOTES:
1)
Inputs 7 and 8 require the
Dual SD/HD-SDI
module in either of the
projector’s option slots. For their selection, see also
3.3, Using the Keypads.

CHANNEL -
A channel is a collection of measurements, locations and settings that
tailor the display of a signal to your specific needs. Since source types and
applications can vary greatly, you will likely want to adjust and define a wide variety
of parameters, such as brightness, contrast, size, etc., in order to customize and
optimize the display from or for a particular source. For example, the display settings
you choose for a VCR source may be very different from those you choose for a
high-resolution computer source, or one signal may simply vary from another signal
used previously through the same input location. Once you have adjusted a display
parameter, such as pixel tracking or contrast, all current settings are collectively
stored in the projector’s memory as a unique two-digit channel, such as
. You
can have numerous distinct channels available for the same input, any of which can
be selected by using the
Chan
key on the keypad followed by the two-digit channel
number.
Shown at right is a sample channel list
as would be available from
Chan
. This is
typically called the
channel list
.
NOTE:
The
Chan
key may display a
channel list or not, depending on what
you have defined for “Display Channel
List” (see
Menu Preferences
later in
this section).
In order to access channels by using
Chan
on the keypad, you must first
create the channels. See below.
To use a new source with the projector, a new channel must be added to projector
memory so that the projector will respond properly to an input signal from that
source in the future. A new channel can be created automatically, as described here,
or it can be copied from an existing channel and then edited as necessary (see
Copying or Deleting Channels
later in this section).
When you select a direct input (
Input 1
,
Input 2
,
Input 3
,
Input 4
,
Input 5
or
Input 6
), the projector’s
existing channels are searched for matching input and signal parameters. If no match
to the incoming input signal is found, a new channel is temporarily created based on
factory-defined defaults for this type of signal. The
channel number
assigned is the
lowest available number from 1-50.
NOTES:
1)
An automatic channel will be discarded unless one or more of its
parameters are changed, and will not appear in the channel list (see below).
2)
If two
channels have the same distinguishing source characteristics except for the reversal
of sync connectors (i.e., H-sync and V-sync, are switched), they are still defined as
distinct channels.
3)
You cannot define a new channel without an incoming signal.
If the incoming signal
does
match an existing channel, the image will be set up and
displayed as usual according to the parameters currently defined for that channel.
