The 100C kit consists of:

New Features

The 100C has several new features to improve functionality and maintenance

Removable cables - All 100C cables are now connectorized. This not only removes one of the most common points of failure, but also allows for easily replacement and packing:

USB power and control - The 100C is now equipped with a micro-USB connector for both power and control. Power can be provided by an wall mounted power supply (included), a USB battery pack (for mobility) or a laptop. The USB port, when connected to a PC, can also control the 100C as well as provide the moderator with an additional view of the front panel information. For more details, download the 100C Application Note (PDF)

Five second countdown - Assisting the moderator to time the interval from the end of asking the question and waiting for a team to respond, the five second countdown timer will beep if no team has responded in the allowed time.

Single button moderator control - The moderator can now control the 100C with a new streamlined single button control. A single click will start the five second countdown (above) before a team has responded or reset the clock once a question is active. A click and hold will reset all in preparation for the next question.


The 100C consists of one timer and three touch bars along with required cables and power supply.
