Chapter 1 Hardware Installation
1.2 Watchdog Installation for GV-600 / GV-650 / GV-750 / GV-800
The Watchdog is a mechanism that is used to determine whether another mechanism is alive or not.
In other words, if for some reason a system is down or "hang up", watchdog will automatically reboot
the PC. The watchdog will restart the computer automatically if it did not receive any response
from the system for more than 5 minutes.
The GV-Series video capture card has two units of reset button pin located in the lower right corner
area. One set should be connected to the motherboard’s reset jumper and the other to the PC’s
reset switch (please see illustration below). Your motherboards’ RST pin position might be
different from the illustration below. Please refer to your motherboard user’s manual for the actual
position.

1.3 Video Extension Card Installation
The GV-System comes standard in 4 video input channels with option to expand to 8, 12, or 16
channels. If you are installing an 8, 12, or 16 channels system then you will need to add video
extension cards to the video capture card. Each capture card can be connected up to 3 video
extension cards and each extension card will provide an additional 4 channels. The video
extension card’s output cord should be connected to the captured card’s video extension port
located in the upper left corner area as illustrated below. For model GV650, GV750, and GV800
users, the video extension ports are located in the right hand side area of your capture card.
