5. Cables 101
• Wires in a wireless world
– What’s up with all these cables?
• Cables and their connectors
– How they look and how they are used
• Care and Feeding

6. 3 Prong Extension Cord
Notice how relaxed the coil is; large diameter and no twist. The pointy end
goes into the wall. Do not unplug by pulling on the cord, grasp the plug. Keep
extra length coiled near the wall or equipment to avoid tripping hazard.

7. VGA – Still the standard; now with audio
Be sure to insert and remove straight, or risk bent pins. Also note that the
connection is trapezoidal and be sure to align properly. The screws are very
important in cases where the female connection is positioned vertically.

8. 3.5mm TRS aka Headphone
Carry signals on 1-3 channels, usually audio. Our VGA cables have one
built in for connecting laptop headphone jack to computer audio port on
input panel. Also comes in larger ¼” size.

9. HDMI – The new hotness
Carries both audio and video signal. Compatible with high definition
devices and HDCP. May be converted directly to/from DVI without audio.
Silly expensive cables, do not lose.

10. Mac Adapters – Why don’t they come with the laptop?
Clients wishing to connect an Apple laptop will need the appropriate adapter.
Most recent models use Mini DisplayPort; older models may use any number
of others. Refer to http://support.apple.com/kb/HT3235. iOS devices require
a different specialized adapter.

11. RCA – Aka Yellow, Red, White
Connect DVD/VCR. Typically color coded for convenience: yellow for
composite video, red for right audio channel, white for left or mono audio.
This is an analog signal. With HD component video, the video is split into 3
channels and carried on separate wires.
Boston University IT Help Center; Classroom Technology Services
12. XLR – Microphones and broadcast audio
They make a satisfying click when fit together securely. When used with a
microphone and amplifier these cables carry phantom power and
produce a loud hum/buzz if there is a faulty connection or grounding.

13. Cat5 with RJ45 connector - Ethernet
Plug it in to connect to the network. Or just connect to 802.11x like
everyone else.
Boston University IT Help Center; Classroom Technology Services
14. Care and Feeding
• Take time to align ends when making
connections and avoid bent pins.
• Grasp at the connector when unplugging, not
cord. Make sure to activate any mechanical
latches.
• Coil in loose loops using the natural lay of the
cable. Do NOT wrap around your arm.
• Report and replace damaged cables.
