2.0 Installation & Initial Configuration 2.1 Overview This chapter discusses the installation procedures for the Cohu 7100 Series camera. To install the camera: 1. Connect Ethernet and Power 2. Assign a valid IP address 3. Go through basic configuration After these steps, the camera should be ready to serve high-quality images to network users. Further configuration topics are covered in later sections. 2.
2.3 Assign the IP Address There are two basic methods to assign the IP address: DHCP or a directed ping packet. Another method is available for advanced users, by using Telnet or HyperTerminal. This information is available in the Cohu 7100 Series Reference Manual. 2.3.1 DHCP If the camera sits on a network that has a DHCP server, the camera can get its address from that server. This feature can be used to have the camera email the administrator with the dynamic IP address it receives from a DHCP server.
Note: For ARP/Ping to work properly on Windows machines, there must be at least one IP address in the ARP table. Type ARP -A at the DOS prompt to ensure that one entry is present. If there is not another IP Address in the table, ping a known device on the network to build an entry (See step 3 below). Once an entry is established in the ARP table, repeat the process to set the IP address for the camera. 3. Ping the camera s IP address. The camera must be fully booted to accept the ping.
2.4.1 Focus If the camera is out of focus, the rapidly updating image on the first page of the wizard can be used to help bring the camera into focus. The image that appears on the page is a reduced image from the center of the camera's field of view. The image on the Focus page displays a number that corresponds to the level of focus. Maximize this number to properly focus the camera.
The image that appears on this page is a half size image that updates more rapidly than a full size image. Watch this image when positioning and framing the image. Use the settings on this page to finalize the general characteristics of the image. crop Cropping an image involves selecting one region of interest in the image and discarding the rest, creating a smaller image. When the image is cropped, rate at which the camera can process and transmit images will increase.
The settings on the Image Settings page of the installation wizard include: lighting Choose the type of lighting that illuminates the camera's surroundings, which determines the color corrections that are needed to account for specific types of lighting. Each category of lighting correction will change the basic color matrix the camera uses to process its images. brightness Set an average value for the overall brightness (gain) control.
2.4.4 Server Settings The final step on the installation wizard contains the most important of the server settings. If necessary, consult the network administrator or ISP service for the appropriate information. Use the text input fields and pull-down menus on this page to adjust the camera s necessary server settings. All settings will be activated once a setting is selected. name Enter a descriptive name for the camera (or leave as default), up to 16 characters long.
set time Sets the time of the camera. The time should be entered in 24-hour format as HH:MM:SS (for example, 20 seconds past 3:15 PM would be 15:15:20). Before adjusting the clock, make sure that the correct time zone is set. Note: A network timeserver can be used to keep time for the camera. See the Cohu 7100 Reference Manual for more information. After completing the settings on the Server Settings page, the installation wizard is finished.
View live, updating images from the camera Retrieve (save) still images Pan/tilt/zoom within images Access the camera's configuration pages Note: Because Netscape and Internet Explorer behave differently, the cameras operate two live connection pages: a server push page for Netscape users and a Java Applet-based server push page for Internet Explorer users. The cameras automatically sense the browser being used and route users to the appropriate live connection page. 2.5.
2.5.2 View Still Images To view still images, click the stop button that appears at the top of the View Images page. Once the stop button is clicked, the camera will take an image and then display it in a new browser page.
