3. Set the termination jumper for each CCI-22 channel to position “A”
(termination connected) as described in “Termination of
Party-Lines.”
If the power supply does not have a termination-disconnect switch,
wire the system as shown in Figure 2-5 on page 2-5. In this
configuration, only the power supply channel’s power and ground lines
are connected to the party-line.
Note: Do not connect the power supply output’s terminated
audio line to the party line.
Do not let the power supply output’s current rating exceed the total
current drawn by the devices powered.
