Rs-232 Serial Port - Harman Kardon AVR 354 Owner's Manual

CONNECTIONS
The FM antenna uses a 75-ohm F-connector. See Figure 13.

The AM loop antenna needs to be assembled. Connect the two leads
to the spring terminals on the receiver. As AM antenna leads have no
polarity, it doesn't matter which of the two terminals is used for either
lead. See Figure 14.

To enjoy XM satellite radio, purchase an XM antenna module designed
for use with XM Ready devices and a subscription to the XM service.
We recommend the XM Mini Tuner and Home Dock Bundle, available
at www.xmradio.com. The older Connect and Play module is also com-
patible with the AVR 354, but it may no longer be available in your area.
An XM Ready-compatible module uses the special connector on the
AVR 354's rear panel that allows you to use the AVR's tuner, including
its 40 preset station locations and remote control. Although you may
use a module with standard audio connections, which may be indicated
for "car and home use," you will not be able to enjoy the AVR 354's
ease of control.

RS-232 Serial Port

The RS-232 serial port on the AVR 354 is used only for software
upgrades. If we release an upgrade for the receiver's operating system
at some time in the future, it may be downloaded to the AVR using this
port. Complete instructions will be provided at that time.
