RS-232 Swap Cable
Swap Cable Construction
A swap cable is used for communication of RS-232 (BKC-DIP, Device Interface Protocol) data between units
by swapping transmit and receive pins. A swap cable can be used between a CT Receiver and a home the-
ater or a swap cable can be used between CT Receivers. A swap cable is intended for one-way communi-
cation between the sender and recipient. RS-232 is not prone to outside interference such as plasma or flu-
orescent light. A CAT5 T568B B&K swap is illustrated below.
Using the CT-1 for System Expansion
One CT-1 IR Routing System Integrator provides a system with connections for up to:
One B&K Home Theater Preamplifier or Receiver with Keypad(s)
And
Three CT Multi-Zone Receivers with Keypad(s)
And
Nine shared identical sources.
The CT-1 IR integrator is the keystone to any multi-CT Receiver install. A single CT-1 can integrate control
for up to three CT Receivers, one B&K Home Theater preamplifier/receiver, nine shared sources and one
CK1.2 Keypad. The CT-1 uses IR as the communication interface between units, it can also pass RS-232
for control of a Home Theater piece. Should future expansion be desired, a CT-1 easily allows additional CT
Receivers to be added to the whole house system. Up to 11 CT-1 IR Integrators can be combined to accom-
modate 21 CT Receivers or 126 zones. The CT-1 can be thought of as the common hub for IR control of the
entire CT system. Each source is connected directly to the CT-1 along with any CT Receivers installed in
the system. All zones will have the ability to control all nine sources when the CT-1 is used.
