Board Troubleshooting
If you cannot execute switches with the new board after it has been installed, the first thing to do is
verify the system’s configuration by entering ~scri5v3! in a terminal emulation program (FIG. 113).
This command retrieves information on the crosspoint size of the virtual matrices (VMs), which
determine the routing of signals.
Note: The configuration file is automatically generated by the system based on its hardware – input
and output boards, expansion boards, front control panel, CPU, etc. If boards are added during
runtime, they are immediately added to the system’s configuration.
From the factory, the automatically generated configuration contains two VMs: VM 0 = all signals and
VM 1 = video signals. The crosspoint size for each VM is set at a full 32x32 for an Enova DGX 32 (eight
input and eight output boards), at 16x16 for an Enova DGX 16 (four input and four output boards), and
at 8x8 for an Enova DGX 8 (two input and two output boards).
If the crosspoint size is less than full (e.g., 24x24 in an Enova DGX 32) and the new board increases the
size past the size indicated on the splash screen, then the system was customized for a non-standard
crosspoint size that is not large enough to accommodate the new board. The configuration file must be
updated before the new board will work (see “Updating the Configuration File” below).
If the crosspoint size is large enough to accommodate the new board and you still cannot execute
switches, contact technical support (see page 62).
Updating the Configuration File
If the configuration file requires updating (as explained in the previous section), read both choices listed
to determine how to proceed.
If the system’s configuration file has not been modified since it was shipped from the factory,
enter ~def! in a terminal emulation program (e.g., DGX Configuration Software – see
page 173) to establish the default configuration of 8x8, 16x16, or 32x32 with two VMs.
If the original configuration has been modified in any way (e.g., local presets were added),
we recommend sending a copy of the modified file to technical support (see page 62),
so they can add support for the board change to the modified file before you download the file
to the CPU (downloading requires XNConnect software; see page 184).
