8x8 DVI Board: Special Information

Application Code for the 8x8 DVI Board
Important: The Optima 8x8 DVI board requires Application Code v1.2.2 or later to work properly (to
determine the version, see directions below). If the enclosure's Application Code version is not at
least v1.2.2, contact technical support (see page 38) for instructions on upgrading the Application
Code.
To determine the enclosure's Application Code version:
1.
Before applying power to the system, attach a PC to the Optima's Control port with a null modem
serial cable (for full instructions, see page 29).
2.
Open HyperTerminal (or other terminal emulation program) on the PC.
3.
Apply power to the system.
4.
Enter ~scrv1i1! to access the splash screen that displays the hardware driver (appcode) version.
5. View the displayed splash screen for system information including the Application Code version
(referred to as the "hardware driver").
An example of an Optima splash screen is shown in FIG. 39.

High-Amperage DVI Outputs on the 8x8 DVI Board
The first set of four connectors (Outputs 1 through 4) on the 8x8 DVI board are high-amperage outputs,
supplying 1 A of maximum cumulative power to destination devices across them. The second set of four
connectors (Outputs 5 through 8) supply 270 mA of maximum cumulative power capability across them.
Important: We recommend checking the documentation for the destination devices for information
about specific power requirements.
If the total power draw of all destination devices connected to either set of four connectors (see above)
exceeds the DVI board's maximum over-current level for those connectors, that set of four connectors
will go into a "protection" condition and shut down to avoid damage to the system. To avoid over-
current shutdown, check the system (during initial installation) for destination devices that may exceed
the DVI board's over-current level using the steps on the following page.
