Overview of External Monitor & Projector Connections

Overview of External Monitor & Projector Connections for the ACUSON® SC2000 Ultrasound System   Upon completion of this course you should be able to:   • Identify and describe the various analog and digital video connections • Identify and describe the input and output connections on the ACUSON SC2000 system • Distinguish between active and passive adapters and provide examples for both Analog •  Found in most labs •  More adaptable •  Max cable length (100 ft) •  More susceptible to image degradation Digital •  Best image quality •  Dependable signal strength & quality •  May include audio signal making it incompatible with older monitors •  May require a conversion  •  Max cable length (50 ft) Video Graphics Array (VGA) • Used for high-definition video • Most common of the analog signals • Only contains the diagnostic area • May support higher resolution playback, but image quality degradation may occur due to cable quality and length Full Screen Diagnostic Area Digital Visual Interface (DVI) • Supports digital and/or analog video • DVI-I (Integrated) - combines digital and analog in the same connector • The analog signal is carried over the 4 additional pins near the blade • This analog signal is the same signal as the VGA format • DVI-D (Digital) - contains a digital signal only   DVI-I DVI-D                                                                                                   DVI-I vs DVI-D Biosense Webster Industries Ultrasound Cable (BWIUS or BWI) • Analog VGA cable • Converts VGA signal to DVI-I signal • Usually around 30 meters (100 feet) long High-Definition Multimedia Interface (HDMI) • HDMI cables commonly used with TVs and computers/monitors • Transfers uncompressed video data and audio data • Can also transfer compressed audio data from an HDMI-compliant source • Displays the full screen DisplayPort • A variation of the HDMI connector • Carries the same digital information as HDMI • Some monitors include both HDMI and DisplayPort adapter ports Phase Alternation by Line (PAL) & National Television System Committee (NTSC) • The two most common video formats are PAL and NTSC • Location/country will determine which of the two video formats will be utilized • Each video format encodes colors differently but both reduce resolution in order to achieve appropriate video format • Displays only the diagnostic area Composite Video • Most basic of video signals • It is a one channel analog video signal that does not contain audio • Displays only the diagnostic area  S-Video  • Different format for standard definition video • Analog video signal • It separates black, white, and color signals to achieve better image quality than composite video • Color resolution is given up in order to achieve better image quality • Displays only the diagnostic area 3 Analog Video-only Outputs:  • VGA • Composite • S-Video 1 Digital & Analog Video Output • DVI (Digital & Analog) 2 Digital Video Outputs • HDMI (Digital Only) • DisplayPort (Digital Only) Full Screen Diagnostic Area Only Input/Output Panel Connections       1. Ethernet ports:  LAN 1 (hospital network connection only)                             LAN 2 (CARTO system connection only) 2. USB ports  3. HDMI port (out to an external monitor) 4. HDMI port (out to a video recorder for recording) 5. HDMI port (in from a video recorder for playback) 6. S-Video port (out to a video recorder for recording) 7. Composite video port (out to a video recorder for recording) 8. VGA port (out to an external monitor) 9. System status LEDs (for use by your Siemens service representative) 10. Disable battery button (for use by your Siemens service representative) 11.  Power cord connector Video Adapters A video adapter may be needed if the following is required: • Conversion must occur between connector types • An analog signal needs to be converted to a digital signal • An audio signal must be removed from a digital/audio video signal Adapter Pros Cons Example Passive  • No power requirement • Not always compatible • Inexpensive • Maximum of 2 outputs (splitter) • Compact • Image quality may be inferior  Active • Virtually no incompatibility issues • Power source required • Multiple outputs (splitter) • Expensive • Maintain high image quality • Size (large) You have now completed the course Overview of External Monitor & Projector Connections for the ACUSON® SC2000 Ultrasound System.  You should now be able to:   • Identify and describe the various analog and digital video connections • Identify and describe the input and output connections on the ACUSON SC2000 system • Distinguish between active and passive adapters and provide examples for both
