3. Select the desired default control mode (General or Extended). See Figure 1. Note: This switch only sets the control mode
the iPod first enters whenever it is docked in the iPort. The iPod can be commanded into either control mode at any time
by the RS-232 controller.
• Dis = Defaults to general (normal) control mode
• En = Defaults to extended (RS-232) control mode
Note: Extended control is only available in the IW-22, and in IW-21 units with RS-232 and Balanced Audio
Upgrade Kits installed.
iPort Rear Connections
See Figure 2
Audio Connector: RJ-45 jack connects to the
audio wall plate via Cat5 cable. The A
UDIO
connection transmits unbalanced or balanced
audio to the audio wall plate, receives IR control
signals from the balanced audio wall plate,
transmits and receives RS-232 control data to
and from the balanced audio wall plate, and
receives DC power from the audio wall plate.
Video Connector (IW-21/IW-22 only): RJ-45
jack connects to the video wall plate.
Unbalanced video wall plates use the included
5-foot RJ-45 to female RCA cable, and require a
male-to-male RCA cable (not included).
Balanced video wall plates require that the
installer make a Cat5/RJ-45 cable, as described
on page 6. The V
IDEO
connection transmits
unbalanced or balanced NTSC video to the
video wall plate.
Supplemental Power Connector (IW-21/IW-22
only):
Removable 4-Pin screw connector that
connects to the balanced audio wall plate’s Aux Power connector via 16/2 speaker wire, for use when the audio
Cat5 cable run is longer than 250 feet in IW-22s and IW-21s with the Balanced Audio Upgrade Kit installed. This supplies DC
power to the iPort in addition to the DC power wires in the audio Cat5 cable, avoiding the voltage drop and associated
performance degradation that can occur when transmitting DC power over long runs of Cat5 cable.
In addition to the connectors, the rear panel also has two Roto-Lock ® clamps. When properly tightened, the Roto-Lock clamps
hold the iPort firmly on the mounting surface.
