6 PC Moderator ™ Installation and User Guide

PC Moderator Installation

The PC Moderator plugs into (and is mechanically mounted to) the VGA port of your

computer. The video display cable then connects to the connector on the VGA cable

exiting the rear of the PC Moderator. This is how the PC Moderator intercepts the video

signals. The PC Moderator intercepts the keyboard signals by cabling to the PC’s PS/2

keyboard port and to the keyboard itself. The PC Moderator receives its power via the

cable connected to the computer’s PS/2 keyboard port. If this cable is disconnected, the PC

Moderator and the VGA display are turned off. An internal lithium battery provides back-

up power for the built-in real time clock when the computer us powered off or the PC

Moderator is unplugged or removed.

The cover of the PC moderator is open only for installation and to change the battery. A

jumper inside can also be removed temporarily in the event that the setup password was

forgotten or otherwise unknown. Only when the cover is removed are the screws that

attach the PC Moderator to the VGA port of the computer accessible. To install follow the

steps below:

1. Turn off your personal computer and unplug the computer from the AC outlet.

(This is important as many PCs supply live power to the keyboard port even when

“turned off”.

2. Find the cable connecting the computer’s VGA port to the video monitor/display.

Remove the cable from the computer port by unscrewing the set screws, either by

hand or with an appropriate screwdriver.

Note: The PC Moderator only operates with monitors that provide a VGA connection. If

your computer or video display adapter provides one or more DVI (Digital Visual

Interface) ports, you will need the DVI Upgrade Kit (included with the PC Moderator DVI

model) to ensure compatibility and security. The upgrade kit includes a DVI to VGA

Shield allowing the PC Moderator to connect to and securely lock to a DVI to VGA

adapter plug. The DVI Cover Lock locks access to DVI ports on the computer or video

adapter to prevent users from using alternative port connections. Refer to

www.pcmoderator.com for product and compatibility information.
