System Expansion
There are many ways to expand upon a CT system. The pages in this section will highlight simple methods
for adding zones to a CT system. For some installations, simple back and forth IR communication will be
needed, other installations will require the use of the CT-1.
General guidelines for expanding a CT system are as follows:
• If identical
sources are being installed, a CT-1 will be required for system expansion.
• If more than two receivers (CT and/or Theater) are to be linked, a CT-1 is required.
• Any source can be shared between the CT system and a home theater system.
• IR can be used as the communication interface or RS-232 can be used as the communica-
tion interface. Typically only one form is used. Both can be used to extract advanced features
such as using Serial Macros.
• IR will have an immediate response time, but IR is more prone to outside interference. RS-
232 could have a slower response time than IR, but it is more reliable. RS-232 will be used for
unidirectional communication only.
• A CT system is not limited to using one of the methods described.
