Sonance CB1 - Manual

The Model

CB1

provides a quick low cost means of

connecting all Sonance IR Receivers and Keypads
to four single or four dual emitters and a power
supply in an infrared repeater system. It can also
provide a low cost means of emitter expansion in
existing systems, or to connect multiple emitters at
the output of other Sonance devices, such as the
ACB1 Amplified Connecting Blocks.

NOTE: A power supply is not

connected to the CB1 when it is used as an emitter expander.

• 2.1 mm coaxial power jack.

INSTALLATION

Fig. 2, next page, illustrates a typical installation using the

CB1

in an IR repeater system. A variety of

Sonance IR Receivers are shown. When configuring a system, please keep the following items in mind:

1. More IR Receivers may be wired in parallel, in the same manner as shown, up to a maximum of twelve.

More than twelve is not recommended because IR noise picked up by the many IR receivers may cause
erratic operation and reduce remote control range.

2. Be sure to connect the +12V, Output, and GND of each IR Receiver and keypad to the respective

+12VDC, SIGNAL, and GND of the connecting block as shown.

3.

Please Note:

a) Each IR receiver draws 10 milliamps.
b) The maximum current for proper operation from the

PS1

Power Supply is 200 milliamps.

c) The maximum current for proper operation from the

PS2

Power Supply is 1000 milliamps.

d) When using combinations of keypads and receivers, do not exceed the maximum current of the power

supplies as noted above.

For example, 6 receivers and 8 emitters could be used with one

PS1

Power Supply. If the current

capability of the

PS1

will be exceeded, use the

PS2

Power Supply instead.

CAUTION: Do not use unregulated 12V power supply adapters from other manufacturers. These
may deliver excessive voltage to the IR receivers and cause them to “latch-up”

. When this occurs,

the “talk-back” LEDs and

VE1

Visible emitters (if used) will stay on continuously!

4. For clarity, connections in this illustration are shown going to a 3-conductor bus in a "daisy chain"

fashion. In an actual installation, however, it is recommended that 3-conductor "home-runs" be pulled from
each room to the

CB1

Connecting Block in the main room. This maintains higher power supply voltage to

each IR receiver and keypad for best operation.

5. The "IR RCVR" jack on the

CB1

allows the

SMR1P

and the

CR1

(with a 3.5 mm stereo mini plug) to be

plugged directly into the

CB1

. You can do this when the

CB1

Connecting Block is within reach of the 7-foot cable;

such as when installing the

SMR1P

in a cabinet where the controlled equipment is behind closed doors.

CAUTION: Plug only Sonance IR Receivers equipped with a stereo mini plug into the IR RCVR jack.
Do not plug in emitters or other devices; to do so will destroy emitters and damage power supplies!

6. The emitter ports are driven in parallel with a 470 Ohm resistor connected in series with each port. The

resistors ensure proper current sharing to each emitter. When using less than 4 emitters, you may plug
them into any of the 4 emitter ports without regard to order.
