Connecting a Home Theater Product
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 installations, both forms may be required. The following diagrams depicts both
IR or RS-232 being used to control the home theater product.
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 switche(s) to pass IR an un-used
IR flasher output. Otherwise the theater receiver/processor Control Outputs can be set to pass IR.
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
Data souce 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.
B&K RS-232 (BKC-DIP) Information
The CT Receiver automatically generates RS-232 (BKC-DIP) message(s) whenever a B&K IR
command is received. A RS-232 (BKC-DIP) message will not be generated if the IR is not a B&K command.
This RS-232 information is transmitted out the CT Receivers six RS-232 XMIT pins and the main RJ-45 jack.
In order to control your home theater piece using RS-232, the IR information must first be received by the CT
receiver. Once the IR is received by the CT receiver, a RS-232 (BKC-DIP) message will be generated and
transmitted to control the home theater unit. The theater receiver will then become an integrated part of the
CT system via RS-232. The generated RS-232 (BKC-DIP) messages only control functions associated with
the home theater processor. These RS-232 (BKC-DIP) messages will not control non-B&K source pieces.
