•  Do not loop the last device in the chain back to the 

TV.  When the device chain is looped, the TV may not 

be able to work with the other devices.

•  Place devices that have only a mechanical (two-

position) power switch at the end of the chain or 
leave the power switch in the On position.  When 
turned Off, IEEE 1394 signals may not be able to 
pass through the device to other devices.

•  Place devices with the slowest communication 

speed at the end of the chain.  Sometimes the 
communication speed will be marked near the IEEE 

1394 connector with an “S” number.  The higher the 

number, the faster the communication speed.  This 

TV has a communication speed of S400.  Devices 

with slow communication speed can interfere with 
IEEE 1394 signals from faster devices.  When using 
NetCommand to set up a digital recording between 
a faster device and a slower device, make the slower 
device the source and make the faster device the 

recorder.

•  Do not use an IEEE 1394 cable over 15 feet in length 

between each device.

•  This TV is an IEEE 1394a device.  It can be used 

with a 1394b system when an IEEE-1394a-to-1394b 
convertor is used.  1394b systems are capable of 
greater distances and multi-room applications.

Compatible A/V devices include some, but not all, cable 

boxes, D-VHS VCRs, A/V discs, and future products.  It 
is also possible to connect devices to the TV that have 
IEEE 1394 connectors but are not compatible with the 

TV or with the NetCommand® control system.  Areas of 

compatibility to consider are:

1.  Digital Video Signals
The TV is able to decode MPEG2 and DV video as 

provided by some camcorders.  If the TV is unable to 
decode the digital signal supplied by your camcorder, try 
S-video with analog audio connections instead.  Other 
types of digital video, such as PC video provided by 
some computers, must be decoded by the source device 
and sent to the TV as analog video, S-video, or HDMI 

video.

2.  Digital Audio Signals
When received with video signals, the TV is able to 
decode Dolby Digital signals and MPEG audio signals.  
Other types of digital audio as provided by some digital 

recording devices, such as MP3 audio and DTS audio, 

cannot be decoded by the TV when received over IEEE 

1394

The TV may not be able to pass incompatible digital audio 

signals on the coaxial digital audio output, however, these 
signals may pass on the IEEE 1394 cable to other devices.

The TV can serve as the control center for IEEE 1394 

audio/video devices, such as VCRs, A/V Discs, tuners, 
cable boxes and amplifiers that are compatible with the 
following IEEE 1394 control standards.

• 

EIA-775 is designed for tuning devices such as cable 

boxes, allowing the device to send simple graphics.  

This standard does not, however, allow the TV to 

control the cable box by IEEE 1394.

• 

AV/C (Audio Video Control) is designed to provide 

basic controls such as play, stop, channel selection, 
and volume, as appropriate for the device.

The IEEE 1394 interface may not provide reliable control 

signals for some DV camcorders, especially older models.  
If your camcorder operates incorrectly or not at all, use 
the camcorder’s control buttons instead of the IEEE 1394 
connection.

Some devices may be a combination of two or more 
types of devices.  For example, there may be a recording 
device that is also a tuning device.  Each portion of the 
device is called a sub-unit.  When you select a device on 
the Device Selection menu that has sub-units, a pop-
up menu will appear so you can select which sub-unit 
section you wish to use.
