You may wish to use a computer rather than a keypad for controlling the
projector and for performing other special functions. From most computers,
connect an RS-232 serial communication cable between the computer and the
projector serial port labeled NETWORK IN (Figure 2-17). Then set the
projector baud rate to match that of the computer. Changing the baud rate is
described in 3.7, Adjusting and Checking System Parameters.

If your computer has a 6-pin XLR connector instead of a 9-pin D connector, or if
you are using the optional Vista
GRAPHX 2-Way Controller, connect to the XLR
jack on the right front panel of the projector, just under the lens.
NOTE: You cannot use two RS-422 connections...

Continue connecting projectors in this way to the last projector in the chain, so
that only the last projector has an empty NETWORK OUT connector. See
Figure 2-21.
Communication parameters such as baud rate must be set to match the particular
controlling device—refer to the documentation that came with the controlling
device in order to determine the proper baud rate. See 3.7, Adjusting and Checking
System...

Each projector can be assigned a unique 3-digit projector number (for example,
001). These numbers are particularly useful when you are working with multiple
linked projectors, enabling you to direct commands to a certain projector rather
than broadcast to all projectors. For complete information on how to assign
projector numbers, see 3.7, Adjusting and Checking System Parameters.
At manufacture every keypad is assigned a default protocol, which is...

The standard IR remote keypad or the optional wired remote can be set to one of
two different protocols —  “C” or “D”. To hard-wire a protocol to “C” or “D” in
either remote, follow Steps 1 through 5:
6WHS#4
Unplug the keypad from the projector (applies to wired remote only).
6WHS#5
Unlatch and open the empty battery compartment on the back of the keypad as
shown in Figure 2-23.
NOTE: A wired keypad will open as shown, but there will be a cable...

NOTE: Although they are similar, a VistaGRAPHX 10K wired keypad cannot be
converted into an IR remote keypad, nor vise versa.

You can also issue software protocol settings through the keypad. These
software commands will be lost when the keypad is either unplugged or when a
battery is removed — the keypad will revert back to the hard-wired jumper
settings (see above) until you enter the...

This section explains how to use the VistaGRAPHX 10K projector once it has been
installed. Please read through these pages before using the projector for the first
time. An understanding of Vista
GRAPHX 10K features and how to access them
will help you to take full advantage of the capabilities of the projector within
minutes. Organization of this section is as follows:...
