• When the RS-232 control mode is active, if the iPod is placed in the dock while in the
Play mode, it will automatically
enter the
Pause mode. The installer or programmer may wish to set the RS-232 control system to automatically send a
Play command to return the iPod to the last playing song when it is inserted in the dock. For RS-232 commands and
programming information, please go to iportmusic.com.
iPort Status Indication (IW-21/IW-22 only)
The logo on iPort IW-21 and IW-22 front panels serves as a Status Indicator (see
Figure 14).
Factory Default Settings:
• When the iPort is first installed and powered-up, the indicator illuminates
DIM* for 2 minutes, then turns OFF.
• When an iPod is docked in the iPort, the indicator illuminates BRIGHT* for
2 minutes, then turns OFF.
• When the iPod is un-docked from the iPort, the indicator illuminates DIM*
for 2 minutes, then turns OFF.
* The user can change these settings to any of three illumination
levels (bright, medium, and dim) via RS-232 or the iPort remote.
Always ON Mode:
The installer or user can defeat the 2-minute turn-off
function (the indicator will operate as above, but will not turn OFF after two
minutes) via RS-232 or the iPort remote.
Always OFF Mode:
The installer or user can turn the indicator OFF in all
modes via RS-232 or the iPort remote.
Note: If power to the iPort is lost or the power supply is disconnected, the Status Indicator will return to the
factory default settings.
