  1. Expansion cards Unit objectives: • Describe video adapters and standards, and install a video adapter • Define sound cards, identify the components of a sound card, and install a sound card • Describe modem standards and identify the components of a modem • Identify the symptoms, probable causes, and potential solutions for problems related to expansion cards

  2. Topic A • Topic A: Video cards • Topic B: Sound cards • Topic C: Internal modems • Topic D: Expansion card troubleshooting

  3. Video adapters • Produce signals displayed by the monitor • Text, images, video • Black & white and color

  4. Creating an image • Phosphorescent coating • Electron beam • Refresh (scanning) rate • Interlacing • Resolution • Color (pixel) depth

  5. Maximum colors

  6. Video standards

  7. SuperVGA • No official standard • Various proprietary schemes • Resolutions and colors varied from: • 640x400 at 8 bits per pixel to • 1600x1200 at 16 bits per pixel • Most common is 800x600 at 8 bpp

  8. eXtended Graphics Array

  9. 15-pin VGA (DE-15) connector

  10. VGA socket

  11. DVI connection types

  12. DVI-D port

  13. DVI-I port

  14. HDMI • Digital format without conversion • TMDS protocol • Eight channels of digital audio • Higher-resolution support • Four connector types: • Types A, B, C, D • Type B has 29 pins, the rest 19 • Compatible with DVI-I and DVI-D

  15. HDMI Type A port

  16. Activity A-1 Identifying video adapter types

  17. Safe handling • Unplug your computer • Work at static-safe workstation • Ground yourself to the chassis • Keep cards inside static-protective bags • Handle cards by their edges or slot cover plate • Don’t touch board components, traces, or edge-connector pins

  18. Drivers • Software that interacts with a device and enables its functions • Some are provided by operating system • Others you must install

  19. Installing an expansion card • Configure DIP switches or jumpers on the card • Shut down PC, unplug it, remove peripheral cables, and open case • Locate empty and available expansion slot of correct type • Remove cover for that slot • Move or remove wires or other expansion cards so you can access the slot • Connect wire assemblies to the expansion board continued

  20. Installing an expansion card, continued • Begin inserting the end of edge connector that’s farthest from the slot cover; when it’s level, gently push card into place • Fix card in place with screws or clips • Connect any wiring assemblies • Close the case, connect peripherals, and start the system • Configure the card • Install required drivers

  21. Video adapter slot types • Built into motherboard • Don’t take up an expansion slot • Common on low-end systems • Might be able to disable on-board video adapter in BIOS • Three types of video expansion slots • PCI • AGP • PCIe

  22. Activity A-2 Installing a video adapter card

  23. Topic B • Topic A: Video cards • Topic B: Sound cards • Topic C: Internal modems • Topic D: Expansion card troubleshooting

  24. PC sound • Motherboard speaker • Beeps and clicks • Creative Labs SoundBlaster • Music, plus beeps and clicks • Digitizing input music • SoundBlaster Pro = the base standard • Sound card functions • Convert digital to analog, and analog to digital

  25. Sound card components • Digital signal processor • Analog-to-digital converter • Digital-to-analog converter • Jacks and ports

  26. A sound card

  27. Sound card connectors Center speaker Rear speakers Microphone Line in Main speakers or headphones

  28. Speakers

  29. Activity B-1 Identifying the components of a sound card

  30. Installation of sound cards • Adapter card type must match expansion bus • With older drives, must attach CD drive’s audio-out cable to sound card • Some sound cards require device drivers from the manufacturer

  31. Activity B-2 Installing a sound card

  32. Topic C • Topic A: Video cards • Topic B: Sound cards • Topic C: Internal modems • Topic D: Expansion card troubleshooting

  33. Modems • Send data signals over phone lines • Modulation • Demodulation • Forms

  34. Riser cards • Specialized slots and cards • Never became popular • Types • AMR • CNR • ACR • Add-on modems generally use PCI

  35. Activity C-1 Identifying your internal modem’s interface

  36. Modem connections RJ-11 connectors RJ-11 jacks: Connect to phone line Optional: connect to a phone

  37. Data transmission speed • Measured in bits per second • Baud = a measure of signal changes per second • Comparable to the frequency of an analog wave • Bits-per-second rate = baud rate × number of bits sent per signal change • ITU defines standards for modems

  38. Activity C-2 Identifying modem connections

  39. Topic D • Topic A: Video cards • Topic B: Sound cards • Topic C: Internal modems • Topic D: Expansion card troubleshooting

  40. Updating drivers New drivers released to Resolve conflicts Update faulty code Add functionality to device Look for most up-to-date drivers on manufacturer’s Web site Usually free download Look for links such as Drivers, Support, or Downloads Update driver via Device Manager or run driver’s installer

  41. Activity D-1 Searching for and installing updated drivers

  42. Video card problems • No video at all • Video scrolls, flips, wavers, or is too large; lines are doubled up • Video flickers • Video is blurry • Image artifacts are displayed across the screen • System freezes during a video change • Video is connected to DVI connector, but monitor displays message that analog connection is disconnected

  43. Sound card problems • No sound • Sound is very low • Sound is distorted • No audio captured • No audio from CD

  44. Modem problems • Modem picks up line and dials, but doesn’t connect • Modem reports no dial tone detected • Connection drops frequently • Modem connects, but only at low speeds • Modem doesn’t work at all • Configuration-related error messages

  45. NIC indicator lights • Observe to see if device is working • Green is typically good • Flash when sending or receiving data • If not illuminated, check Device Manager • Check device properties

  46. Activity D-2 Troubleshooting expansion card problems

  47. Unit summary • Described video adapters and standards, and installed a video adapter • Defined sound cards, identify the components of a sound card, and installed a sound card • Described modem standards and identified the components of a modem • Identified the symptoms, probable causes, and potential solutions for problems related to expansion cards
