Coupling Two CT Receivers - Maximum 12 Stereo Zones

Two CT Receives can be coupled together using IR for some simple installations. The following diagram depicts a system for up to 12 stereo zones, with NO identical sources, and two-way communication. IR is simply being allowed to flash both receivers regardless of which keypad generates the IR command. All key- pads can be programmed using the code-set 128. Whole House control (code 000) as well as control of any zone, from any zone is also possible. The flasher outputs for this configuration need to be set to “ALL INPUTS”. IR output number nine is used to pass IR from the back panel of one CT Receiver to the front panel of other CT Receiver. Tab nine of BKcSuite is used to configure the flasher settings. Be sure the Front Panel to IR Flasher is set to “NO” (Default Setting).

RS-232 (BKC-DIP) can be used as the communication interface for a second or third CT Receiver. When linking CT Receivers together with RS-232, a swap cable should be used (see page 27). A swap cable will connect between the pri- mary receiver’s RS-232 XMIT (Transmit) port and the RJ-45 jack of the subse- quent receiver(s). Data will transmit in one direction only. A swap cable

should not be connected between RJ- 45 jacks.

Additional CT Receivers can be added in a chain. RS-232 data will transmit in one direction only.

To simplify the installation, use the RJ- 45 to 5 position phoenix adapter, see page 8.
