5. Before mounting the balanced audio wall plate into its electrical
box be sure the IR/RS-232 control switch is in the
RS-232
position
(see
Figure 11).
IMPORTANT: The switch must be in the RS-232
position,
even if the system will only be using IR control.
6.
For installations where the balanced audio wall plate is located more
than 250 feet from the iPort:
Run a length of 16/2 speaker wire through
the wall from the wall plate’s A
UX
P
OWER
connector to the iPort’s
S
UPPLEMENTAL
P
OWER
connector as shown below in
Figure 12. (The
S
UPPLEMENTAL
P
OWER
connector has two parallel sets of terminals — you can
use either set.) This will avoid performance degradation caused by a loss of
DC voltage over Cat5 wire runs longer than 250 feet.
7. Install the wall plates into electrical boxes in the rooms near the audio and
video systems.
IMPORTANT: Do
not install the iPort wall plates in the same electrical
boxes as AC house wiring, a light switch, or any other high-voltage
device or control. The two wall plates can share a gang box with each
other or with controls such as A/B speaker switches, infrared receivers,
and volume controls, if these other devices are rated as Class 2 devices
according to the National Electrical Code.
8. Use a stereo RCA audio cable to connect the balanced audio wall plate’s
A
UDIO
connectors to a source input on the audio system, as shown in
Figure 10, page 13.
9.
For IR control systems:
Use a 3.5mm cable (mono or stereo) to connect the
balanced audio wall plate’s IR connector to the IR control output of a com-
patible IR control system. (Please go to iportmusic.com for a complete list
of compatible control systems.)
10.
For RS-232 control systems:
Use the supplied RS-232 cable to connect
the balanced audio wall plate’s RS-232 connector to the control output of
a compatible control system, as shown in
Figure 10, page 13. The wall
plate RS-232 connector pinout is:

operation go to iportmusic.com.
11. Use a composite video cable to connect the unbalanced video wall plate’s
V
IDEO
connector to the composite video input of the local-zone video sys-
tem, as shown in
Figure 10, page 13.
