B&K CT600 - Manual (Page 34)

Adding a Home Theater
B&K manufactures Home Theater preamplifier/processors and receiver/processors. Any of these products
can be combined to share sources in a CT system. Depending on which form of control communication you
wish to use (IR or RS-232), B&K can accommodate either or both. Typically only one form of communication
is needed, however for some advanced installations, both forms may be required. The following diagrams
depicts both IR or RS-232 being used to control the home theater product.
The CT-1 allows an easy method to interface between a home theater and a whole house distribution system.
Once a B&K home theater is added to the system, the theater becomes a sub-system of the main CT sys-
tem. You are making the theater a CT zone. IR Code-sets work consistently with the home theater line as
they do with the CT line. Code-set 001 is used for zone 1, code-set 002 is used for zone 2. Typically you
should use the RS-232 connection method because RS-232 will not pick up outside interference such as
plasma or fluorescent light. An RS-232 swap cable does not need to be installed when using the CT-1.
The illustrations below will also allow for sources that are only used in the theater zone. Control of those
sources is maintained through the theater keypad or IR sensor. Set the DIP switches accordingly. Refer to
the CT-1 manual for more detailed information regarding the CT-1.
You may not need both forms of communication connected, only connect what you need.
IR = 1/8” mono mini jack
RS-232 = CAT5 straight through cable
The Home Theater sensor plug (three position phoenix) can be used either for a Keypad (CK1.2) or for an IR
sensor located in the theater room. RS-232 XMIT ports on the CT Receiver back panel are outputs only.
RS-232 Data (BKC-DIP) can be obtained from any zone RS-232 XMIT pin. If all keypad ports are being used
by keypads, the RS-232 data, 12VDC power, and GND can be obtained from the SLAVE OUT RJ-45 jack
(PINs 5, 1, & 3 respectively) on the panel of the CK1.2 Keypad. Simply run a three position wire (or extra
CAT5) to the nearest keypad.
