Pre-wiring the BA-2430 System
The 2430 System is designed to operate using two types of wire. Standard Cat-5 Network cable is used for keypad control of the system. Two- or
four-conductor audio cable sends the audio signal to each pair of speakers in the four listening zones. Both types of wire should be concealed in the
walls of the home and are installed on the back side of the BreatheAudio Allport™ (fig. 1). Proper termination of each of the cables is crucial to reliable
operation of the entire system.
Be sure to label each Cat-5 for its appropriate zone. This is important for future reference.
Terminating Cat-5
Be careful not to place the Cat-5 runs next to AC power cables. Doing so will cause noise and interference in the data being sent to and from each zone.
To avoid this interference it is best to leave at least one stud space between the Cat-5 and AC power lines. If it is necessary to cross AC wires, it should
always be done at a 90 angle.
The Cat-5 cables are terminated using a modular RJ-45 jack (fig. 2). This is the same type of jack used on computer Ethernet cables. Each Cat-5 cable
has four colored wires twisted together in pairs inside an outer jacket. Each pair consists of a solid and striped wire. The colors are green, orange, blue,
and brown. The order of the colored wires inside the RJ-45 determines proper communication between the keypads and the main amplifier unit. The
2430 System uses the standard Ethernet or network color scheme referred to as 568A.
