INSTALLATION AND CONNECTIONS RS-232 Connections The AVR 630 is equipped with an RS-232 Serial Connection Port e that may be used for two purposes. When the port is connected to a compatible, optional, external computer, keypad or control system the AVR 630 is capable of bi-directional communications that enable the external system to control the AVR, and for the AVR to report status and handshake data back to the controller. Use of the RS-232 port for this type of control requires specific technical knowledge, and we recommend that any connection and programming for control be made by a trained installer or technician familiar with the equipment being used. The RS-232 port may also be used as an access point through which the AVR 630's operating system and surround mode memories may be updated via connection to a compatible computer. At the time that any upgrade is available, instructions for making the connection and installing the upgrade will be available through the Product Support area of the Harman Kardon Web site at harmankardon.com. The physical connection to the AVR 630's RS-232 port is a standard D-SUB 9 connection but to assure compatible and proper operation, specific software commands and pin wiring schemes may be required. AC Power Connections This unit is equipped with two accessory AC outlets. They may be used to power accessory devices, but they should not be used with high-current draw equipment such as power amplifiers. The total power draw to each outlet may not exceed 100 watts. The Switched AC Accessory Outlet ⁄ is powered only when the unit is on. This is recommended for devices that have a mechanical power switch that may be left in the "ON" position. NOTE: Many audio and video products go into a Standby mode when they are used with switched outlets. This type of product may not operate properly when used with the switched outlet. The Unswitched AC Accessory Outlet ¤ is powered as long as the AVR is plugged into a powered AC outlet. The AVR 630 features a removable power cord that allows wires to be run in advance to a complex installation so that the unit itself need not be installed until it is ready for connection. When all needed connections have been made, connect the AC Power cord to the AC Power Cord Jack ‹. The AVR 630 draws significantly more current than other household devices, such as computers, that use removable power cords. For that reason, it is important that only the cord supplied with the unit (or a direct replacement of identical capacity) be used. Once the power cord is connected, you are almost ready to enjoy the AVR 630's incredible power and fidelity! 18 INSTALLATION AND CONNECTIONS

INSTALLATION AND CONNECTIONS
RS-232 Connections
The AVR 630 is equipped with an
RS-232 Serial
Connection Port
e
that may be used for two pur-
poses. When the port is connected to a compatible,
optional, external computer, keypad or control system
the AVR 630 is capable of bi-directional communica-
tions that enable the external system to control the
AVR, and for the AVR to report status and handshake
data back to the controller. Use of the RS-232 port for
this type of control requires specific technical knowl-
edge, and we recommend that any connection and
programming for control be made by a trained installer
or technician familiar with the equipment being used.
The RS-232 port may also be used as an access
point through which the AVR 630’s operating system
and surround mode memories may be updated via
connection to a compatible computer. At the time
that any upgrade is available, instructions for making
the connection and installing the upgrade will be
available through the Product Support area of the
Harman Kardon Web site at harmankardon.com.
The physical connection to the AVR 630’s RS-232
port is a standard D-SUB 9 connection but to assure
compatible and proper operation, specific software
commands and pin wiring schemes may be required.
AC Power Connections
This unit is equipped with two accessory AC outlets.
They may be used to power accessory devices, but
they should not be used with high-current draw equip-
ment such as power amplifiers. The total power draw
to each outlet may not exceed 100 watts.
The
Switched AC Accessory Outlet
⁄
is powered
only when the unit is on. This is recommended for
devices that have a mechanical power switch that may
be left in the “ON” position.
NOTE:
Many audio and video products go into a
Standby mode when they are used with switched out-
lets. This type of product may not operate properly
when used with the switched outlet.
The
Unswitched AC Accessory Outlet
¤
is
powered as long as the AVR is plugged into a
powered AC outlet.
The AVR 630 features a removable power cord
that allows wires to be run in advance to a complex
installation so that the unit itself need not be installed
until it is ready for connection. When all needed
connections have been made, connect the AC
Power cord to the
AC Power Cord Jack
‹
.
The AVR 630 draws significantly more current than
other household devices, such as computers, that use
removable power cords. For that reason, it is important
that only the cord supplied with the unit (or a direct
replacement of identical capacity) be used.
Once the power cord is connected, you are almost
ready to enjoy the AVR 630’s incredible power
and fidelity!
