D-73d Series Installation/Operation Manual 93
• Diagnostics: Select Diagnostics from the Display Device - Configure menu, then
select Red, Green, Blue, Yellow, Cyan or Magenta to display only that color channel
(simulating a filter of that color). This can be useful for calibration or measurement
purposes.
To restore the normal picture (all colors), select White.
• Altitude: Select Altitude from the Display Device - Configure menu to control the
operation of the projector’s cooling fan.
In most cases, the default setting (Auto) will maintain the correct operating
temperature. If the display frequently turns off due to overheating, or in certain
high-altitude operating environments, you may need to change this setting to High.
Network: The options in the Network menu allow you to configure the network
communication features.
• IP Configuration: Select IP Configuration from the Network menu to either set the
IP address, subnet mask and default gateway of the Dimension Digital Controller
manually or obtain these settings automatically, from a DHCP (Dynamic Host
Configuration Protocol) server. (Most broadband routers and gateways support
DHCP.) You can also test the network connection from this menu.
• DHCP: To enable the DHCP client in the Dimension Digital Controller, select
DHCP from the IP Configuration menu and set it to On. With this setting, the
Dimension Digital Controller’s IP address, subnet mask and default gateway are
assigned by the local DHCP server.
To manually configure these values, set DHCP to Off.
• IP Address: Select IP Address from the IP Configuration menu to manually
configure the IP Address of the Dimension Digital Controller, as follows:
1. Press or to select the first, second, third or fourth byte of the address.
2. Press or to set the value of that byte. The range is from 0 to 255 inclusive.
3. Repeat Steps 1 and 2 for all four bytes of the address.
4. Press MENU when you have finished setting the address.
• Subnet Mask: Select Subnet Mask from the IP Configuration menu to manually
configure the IP subnet mask. The procedure is similar to that for setting the IP
address.
• Default Gateway: Select Default Gateway from the IP Configuration menu to
manually configure the default IP gateway. The procedure is similar to that for
setting the IP address.
• Communication Test: Select Communication Test from the IP Configuration
menu to verify proper operation of the network communication link.
To start the test, select Start Test from the Communication Test menu. The
Dimension Digital Controller displays the message “Performing Communication
Test.” When the test completes, the Dimension Digital Controller displays either
“Failed” (along with the error that occurred) or “Succeeded.”
The IP Address, Subnet Mask and Default Gateway items in the
IP Configuration menu are disabled (grayed out) when DHCP is
enabled.
