RS-422 Ports
Some computers can provide 
RS-422 serial communications (often through a plug-in
adapter or external converter) rather than the more common RS-232. RS-422
communication has differential “transmits-and-receives” and is generally better
suited for long distances than is RS-232 communication. RS-422 is not compatible
with RS-232—connecting one to the other could damage the equipment at...

 WARNING 
Do not use an RS-422 port unless you are using a
computer with RS-422 capability. The voltage levels of
this signal can damage incompatible equipment.
You may wish to use one or more external Marquee Signal Switchers or a third party
switcher in order to significantly increase the number of sources you can select. If
you are using a Marquee Signal Switcher, connect the switcher’s RGB...

Figure 2.29. Adding Another Projector via RS-232
RS-422 NETWORK: To control multiple projectors with a computer/controller having
an RS-422 interface, first set them all to the same baud rate needed, then chain the
projectors together by connecting the 
RS-422 PORT 2 connector of the first projector
(already connected to the computer/controller) to the 
RS-422 PORT 1 connector of the
next projector in the chain.

For either type of network, continue connecting projectors in this manner until
you’ve reached the last projector in the chain, so that only the last projector has an
empty 
RS-232 OUT (or RS-422 PORT, if applicable). See examples below.
Figure 2.31. Assorted Networks (NOT split)
Note that communication parameters such as baud rate must be set to match the
particular controlling device before connecting as a network—refer to the
documentation that...

Roadster/Vista User’s Manual
In a typical network, broadcast serial communications or messages destined for a
specific projector travel through all serial ports in each projector regardless of
whether the messages originate from an RS-232 or RS-422 source (refer back to
Figure 2.31, bottom example). The communication path depends on the serial cabling
connected at each projector.
You may prefer the option of two separate communication paths—RS-232 or RS-
422—in your network,...

Figure 2.33. Two Types of Split Networks
Each projector can be assigned a unique 3-digit projector number (for example, 001).
These numbers are necessary when you are working with multiple linked projectors,
enabling you to direct commands to a certain projector rather than always
broadcasting to the entire network. For complete information on how to assign
projector numbers, see 3.7, Configuring System Parameters.
NOTE: To loop a single incoming...

At manufacture every keypad is assigned “A” as its default protocol, which is simply
a collection of settings that determine how the keypad operates. Once assigned, this
protocol remains in effect until it is changed—that is, the keypad will operate as it
currently does until you change its protocol.
Protocols are most useful for multiple-projector applications. For example, you might
want to change a keypad protocol if you are working with two...

Step 1
Unplug the keypad from the projector (applies to wired remote only).
Step 2
Unlatch and open the empty battery compartment on the back of the keypad as shown
in Figure 2.35.
NOTE: A wired keypad opens as shown, but a cable passes through the battery
compartment cover.

Step 3
Find the 4 jumpers located along the latching side of the battery compartment. These
jumpers set the keypad protocol and other settings so...

NOTE: A wired keypad can be converted into an IR remote keypad, and vice versa.
Follow the settings shown above, adding or deleting the cable and batteries as required.
The cable with 3-pin XLR connector is available separately from your dealer.
SHORTCUT METHOD:
You can also issue software protocol settings through the keypad. These software
commands will be lost when the keypad is either unplugged or...

If desired, you can convert an IR remote keypad into a wired remote keypad and vice
versa (available February 2000).
TO CHANGE FROM INFRARED TO WIRED:
• Remove battery compartment cover from back of keypad.
• Remove batteries.
• Wait 1-2 minutes.
• Plug the keypad cable (available separately) into the empty battery
compartment. Make sure that the battery cover is notched smoothly to
accommodate the cable.
• Set keypad protocol as desired, using...
