How to Connect Your Laptop to Equipment in a COL Room
This guide explains how to connect your laptop to the COL system so that your screen content is displayed on the projector, included in the lecture recording, and so that you may access the Internet.
Please note: The image that shows on the projector is what will be displayed in the recording.
Cables at the Instruction Desk
At the front of the room, the instruction desk will have one or more cables available for connecting your laptop to the system:
HDMI Cable
The HDMI (High-Definition Multimedia Interface) cable is the most commonly available connection in COL rooms. It transmits both video and audio into the COL system. Most laptops made in the last five years are equipped with an HDMI port. If your laptop lacks an HDMI port, you'll need to bring your own adapter to connect the cable.
To connect via HDMI:
- Insert the HDMI cable into your laptop.
- If the room has a Crestron touch panel, tap "INSTRUCTOR HDMI" to project the display.
- In rooms without a Crestron touch panel, the laptop display should automatically appear on the projector within a few moments of connection.
Note: COL does not provide HDMI adapters; bring one if needed.
Ethernet Cable
Some classrooms also have an Ethernet cable for wired Internet access. If you are unable to connect to the University’s Wi-Fi, use the Ethernet cable to get online.
To connect via Ethernet:
- Insert the Ethernet cable into your laptop’s Ethernet port, or use an Ethernet-to-USB adapter if needed.
- To disconnect, press down on the tab to release the cable.
Locating the Cables
Laptop cables may be stored in one of these locations around the instruction desk:
Laid on the Desk
The cables may located in the labeled silicon holder on top of the desk.
Under an Outlet Cover
If the cables are stored under an outlet cover, gently pull up to extend the cables.
Important: Do not unplug the data cable connecting the Crestron Touch Panel to the system.
In a Cable Retainer
Pull the needed connectors upwards to extend their cabling.
