10. If desired, on the Virtual Map screen menu bar, click Print Maps to create a hard copy map of the virtual system. If you send the map to a color printer (select the printer by clicking on File > Select printer on the main screen), the map prints with the red plane mapped in red, the green plane in green, the blue plane in blue, the horizontal plane in black, the vertical plane in yellow, and the audio plane in olive.

The printed virtual map is invaluable as a wiring guide during installation, or as a reference at any time. See chapter 2, “Installation”.

11. On the Virtual Map screen menu bar, click Return to Main to return to the main screen (figure 3-2). Note that the number of inputs and outputs on the main screen matches the number of inputs and outputs that were created by the virtualization.

The system virtualization is now complete and the virtual map has been stored in BME 0. Unless the map is destroyed (the memory of the BME is corrupted), or the system configuration changes (the size, type, or number of BMEs changes), there is no need to run the Virtualization/Control program again. The program can, however, be run for the control functions (such as establishing ties and setting audio gain and attenuation) at any time.

Reasssigning virtual I/O connectors

The Virtual Map screen lets you make simple corrections to the virtual map to reflect actual physical input and output connections.

Assume a 42-input x 42-output system consisting of one wideband, one sync, and one audio BME (figure 3-3); the wideband BME has 126 inputs and 126 outputs, leaving 2 input BNCs and 2 output BNCs unmapped. Further assume that a cable in the middle of the bundle, say the virtual input 20 green video plane cable, breaks. If the switcher is mapped in a repeating pattern (RGBRGB...RGB), physical input connector 59 has the bad cable connected.

Depending on the cables used and how the cables are arranged in the system, removing the cable connected to physical input connector 59 could entail removing numerous cables that block connector 59. Removing so many cables risks further cable damage or reconnecting the cables to the wrong connectors.

A different solution is to map one of the unused physical input connectors as the virtual input 20 green video plane cable. Mapping an unused connector eliminates the need to remove all of the cables, including the cable on input connector 59.

Each video plane on the Virtual Map screen is represented by a different color. In an RGB matrix, the R, G, and B BNCs are represented by red, green, and blue circles. Unused connectors are shown in white. You can select a virtual input on the Virtual Map screen, either by clicking on one of the BNC connectors for that input or by selecting a specific virtual input in the Virtual Ins or Virtual Outs Map field, the boxed list to the right of the screen (figure 3-6). When a virtual input is selected, all of the associated connectors for the selected virtual input, on all BMEs on the Virtual Map screen turn light blue.

When a virtual input or output is selected, the Virtual I/O Map field identifies the physical connectors for each virtual plane on all BMEs for a selected virtual input or output. The field identifies each physical connector with a 5-character code. On the Before reassignment view of figure 3-6, the virtual input 20 green video plane connector is coded 0i059, which translates to BME 0, input connector 059. If the List-View Inputs radio button is selected, the Virtual Ins list field displays the same information.
