III. DISCUSSION 23Interfaces andCompatibilityCamera Direct PrintingThree interface terminals are provided on the side of the body. The EOSDigital Rebel XT camera has a USB 2.0 Hi-Speed, mini-B connector thattransfers data from the camera to a computer approximately ten timesfaster than the USB 1.1 connector on the EOS Digital Rebel camera.Video output is provided for both NTSC and PAL, and provision is madefor the RS-60E3 Remote Switch.It is possible to operate the XT wirelessly via either the RC-1 or RC-5 Remote Controller.The camera’s grip has a built-in wireless remote control receiver. The system iscompatible with all shooting modes and has a range of about 5 meters/16.4 feet, frontand center. To enable this function, press the Drive Mode button to display theSelf-timer/Wireless remote control icon on the top LCD information panel.The XT complies with Design rule for Camera File System 2.0 and Exif 2.21, updated tosupport the expanded Adobe RGB color space often used for printed materials. Whensoftware compatible with Exif 2.21 is used, images captured with the XT and tagged asAdobe RGB will open automatically in the Adobe RGB color space. Also, when a printer thatcomplies with Exif 2.21 is used, the printer will adjust color saturation for improved results.As with the EOS Digital Rebel camera, the EOS DigitalRebel XT camera is currently compatible with PictBridge,CP Direct and Bubble Jet Direct printers. By operating thecamera without the involvement of a computer orspecialized software, all three of these systems printJPEG images that comply with DCF. DPOF print orderingfor direct printing is also possible, as is batch printing of specified images. The basicspecifications for these three printing methods are the same as with the EOS 20D. Alsoshared with the EOS 20D is the XT’s compatibility with highspeed printing when thecamera is connected to a BubbleJet printer via PictBridge. To promote direct printing, theXT’s default Communications menu setting is Print/PTP. PC connection is the alternative.The EOS Digital Rebel XT camera alsohas the same Direct Print or Easy Printingfeature found in the latest PowerShotcameras. (Unlike the PowerShotcameras, the XT does not have a featureto transfer images directly to a personalcomputer.) When the XT is connected toUSB TerminalRS-60E3 RC-5
