CONNECTIONS

Figure 14 – AM Antenna

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 254, but it may no longer be available in your area.

An XM Ready-compatible module uses the special connector on the AVR 254’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 254’s ease of control.

RS-232 Serial Port

The RS-232 serial port on the AVR 254 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.
