Audio and video inputs for two computers and an auxiliary source are provided on the sides of the cart. Facing the front of the cart, the "COMPUTER 1" and "AUX" inputs and a pair of AC power outlets are located on the right. The "COMPUTER 2" input, power supply cable, and multi-pin system input/output cable is on the left. The multi-pin cable carries audio, video and control signals between the cart and devices located elsewhere in the courtroom. The "AUX" input can be used to connect to various external audio and/or video sources.

To use the computer inputs, connect a cable between the computer input connector on the cart and a laptop or other computer's VGA output. The system is capable of displaying computer resolutions up to 1280 x 1024. A cable may also be connected between the computer audio input connector on the cart and a computer's headphone or line level audio output. If the computer's headphone output is used, the volume level of the computer may need to be adjusted to avoid distortion.

Once connected, computers or auxiliary sources are selected using the touch panel.
