It provides immediate system information, power status and serial port settings for the DVS 304 unit. Figure 4-2 — System Status page DVS 304 • Ethernet Control 4-3 Ethernet Control, cont’d Configuration The Configuration tab includes pages that show the current system settings, scaler settings, passwords and firmware upgrade data for the DVS 304 series. System Settings page The Systems Settings page (figure 4-3) consists of fields where you can view and edit IP administration and system settings. Date and time information can be easily updated. Figure 4-3 — System Settings page IP settings fields The IP settings fields provide a location for viewing and editing settings unique to the Ethernet interface. After editing any of the settings on this page, click the Submit button. Explanations for some of these fields follows. Unit Name This name field can be changed to any valid name, up to 12 alphanumeric characters. N The following characters are invalid in the name: {space} ~ @ = ‘ [ ] { } < > ’ “ ; : | \ and ?. DHCP The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating the configuration of computers that use TCP/IP. DHCP can be used to automatically assign IP addresses, deliver TCP/IP stack configuration parameters such as the subnet mask and default router, and provide other configuration information such as the addresses for printer, time and news servers. For specific settings information, see your system administrator. IP Address The DVS 304 IP Address field contains the IP address of the connected scaler. This value is encoded in the flash memory in the scaler. Valid IP addresses consist of four 1-, 2-, or 3-digit numeric subfields separated by dots (periods). Each field can be numbered from 000 through 255. Leading zeroes, up to 3 digits total per field, are optional. Values of 256 and above are invalid. 4-4 DVS 304 • Ethernet Control The default address is 192.168.254.254, but if this conflicts with other equipment at your installation, you can change the IP address to any valid value. N Editing the Extron IP address while connected via the Ethernet port can immediately disconnect the user from the scaler. Extron recommends editing this field using the RS-232 link and protecting the Ethernet access to this screen by assigning an administrator’s password to qualified and knowledgeable personnel only. Edit this field as follows: 1. Click in the DVS 304 IP address field. The graphic cursor becomes a text cursor. 2. Edit the address as desired. 3. Press the Tab key on the keyboard or click in another field to exit the IP Address field. 4. Click on the Submit button to make the address change take affect. Gateway IP Address The Gateway IP Address field identifies the address of the gateway to the mail server to be used if the DVS 304 and the mail server are not on the same subnet. The gateway IP address has the same validity rules as the system IP address. Subnet Mask field The Subnet Mask field is used to determine whether the DVS 304 is on the same subnet as the controlling PC or the mail server when you are subnetting. Date/Time Settings fields The Date/Time Settings fields (figure 4-3) provide a location for viewing and setting the time functions. The adjustable variables are month, day, year, hours, minutes, AM/PM, and (time) zone. Change the date and time settings as follows: 1. Click the desired variable’s drop box. A drop down scroll box appears. 2. Click the desired value. N For quick setting of the date and time, click the Local Date/Time. Click Cancel at any point before submitting to exit any field changes. The unit is not updated with those changes The screen refreshes and shows the current device settings. 3. Repeat steps 1 and 2 for all variables that need to be changed. 4. If appropriate, select the Daylight Savings radio button for the DVS’s region, to turn on the daylight savings time feature. N When a locations daylight savings time is turned on, the switcher automatically updates its internal clock between Standard Time and Daylight Savings Time in the spring and fall on the date that the time change occurs in the country or region selected. When Daylight Savings Time is turned off, the switcher does not adjust its time reference. 5. Select the Zone variable that is relevant for the DVS’s location. N The Zone field identifies the standard time zone selected and displays the amount of time, in hours and minutes, that the local time varies from the GMT international time reference. 5. Click Submit. The device is updated with the new settings. DVS 304 • Ethernet Control Ethernet Control, cont’d Scaler Settings page The Scaler Settings page (figure 4-4) simulates elements of the DVS 304 menu system, but also allows you to set video input signals (for inputs 2 and 4 only), define output resolutions, and remotely define advanced configurations. Note that resolutions in the Resolution drop-down menu are linked to refresh rates as shown in the “Available Scaler ...
