2 Modula SDI Digital Video Enclosures This Boards & Specifications section contains specific board installation information for boards available for the following SDI Modula enclosure models: Modula Enclosure Models 3-0 3x3 SDI Digital Video Enclosure 3-7 3x3 SDI Digital Video & Wideband Video Enclosure x3 SDI Digital Video & Standard Video Enclosure x3 SDI Digital Video & S-Video Enclosure These enclosures primarily hold SD-SDI and HD-SDI digital video boards. Depending on the enclosure model, other boards may also be included for switching other video and audio signals within the enclosure. The chart on the following page indicates which boards are available for each enclosure model. Cabling information and specifications are found in the subsequent chapters based on signal type. These enclosures can hold up to boards ( input and output) with connectors each. This allows for a full configuration of 3x3, as well as subsets such as x3, x, or x. Upgrading in the Field One of the advantages of a Modula enclosure is that boards can be added (or replaced) in the field. To determine which boards can be added to your model, see the chart on the following page and contact your sales representative. Boards can only be added to their respective slots, i.e., input boards can only be added to input slots. See the Installation & Setup section of this binder for board installation information. If you have questions, contact your AutoPatch Dealer or Technical Support. Modula Boards & Specifications i

Follow the sheet exactly; the system was programmed at the factory to operate only as indicated on the sheet. Modula S-Video boards are equipped with locking S-Video connectors. When used in conjunction with AutoPatch S-Video cables, the connectors and the cables lock into place. Cables with standard S-Video connectors may also be used, but will not lock. To connect S-Video inputs and outputs, fasten the cables onto the input and output S-Video connectors (see Figure ). S-Video OUT 7 Figure : Fasten the cable onto the connector To fasten a locking S-Video connector, either pull back on the housing of the connector (see Figure 9) while pushing the connector in, or hold the connector at a slight angle to the right while pushing in. Housing Figure 9: Pull back the housing to fasten the connector To remove a locking S-Video connector, pull back on the housing of the connector. Caution: To avoid damaging a locking S-Video connector or board, be sure to pull on the connector housing instead of the cable. 3- Modula Boards & Specifications

12 S-Video Configuration Files 3. S-Video Configuration Files X N Connect (the configuration software program on the AutoPatch Software CD shipped with the Modula) supports Modula systems with S-Video connectors. Important: Use this software only if you need to change the configuration information from the original specification. In Modula systems, each signal in a component signal has its own signal path. When you select a connector in the virtual matrix view, the properties box in the right pane indicates the two signals for each S-Video connector as appended numbers. Signal Paths Example The connector for Input contains two signal paths (see Figure 0): S-Vid V_IN_00. for the Y signal path S-Vid V_IN_00. for the c signal path S-Video Figure 0: Input connector properties showing signal paths for one S-Video connector See Chapter of the Installation & Setup section of this binder for information on managing configuration files with X N Connect.

24 Adjusting Output Controls. Adjusting Output Controls Stereo output boards in a Modula SDI Digital Video enclosures come with potentiometer gain control which can be adjusted at any time during normal operation. A small AutoPatch screwdriver for adjusting gain is included with every Modula Distribution Matrix. Stereo output boards are set to unity gain at the factory. To adjust output gain control using potentiometers:. Route a source (input) to the first destination (output).. Adjust the output gain for the destination to the desired decibel level by turning the corresponding potentiometer (see Figure 7) clockwise to decrease gain, counterclockwise to increase gain.

25 Stereo Audio.3 Adjusting Input Gain All stereo audio input boards in Modula SDI Digital Video enclosures come with potentiometer gain control. Adjustments can be made at any time during normal operation. Caution: Only a qualified dealer should adjust input gain. The purpose of controlling the input gain (the nominal level of the signal from the source device) is to allow source signals of various amplitudes to be equalized before they are routed and the volume is adjusted. Equalizing source levels provides a consistent reference for volume adjustments and eliminates jumps when routing a new input to an output. Typical uses for input gain include switching consumer and professional grade audio equipment (whose levels can vary noticeably) in the same routing system. Input gain adjustment is also used for equalizing amplitudes between balanced and unbalanced inputs. Stereo audio input boards are set to unity gain at the factory. A small AutoPatch screwdriver for adjusting gain is included with every Modula Distribution Matrix. To use potentiometer input gain to equalize input levels:. Route a source (input) to the first destination (output)..
