PIP 422 and PIP 444 Picture-in-Picture Processors 1 Chapter One Introduction About the Picture-in-Picture Processors Features
Introduction, cont’d Introduction About the Picture-in-Picture Processors The Extron PIP 422 is a 2-input video picture-in-picture processor. The PIP 444 is a 4-input picture-in-picture video processor. The processors accept up to two (PIP 422) or four (PIP 444) composite video, S-video, or component video input signals. Both units can output the signals simultaneously to three displays: one composite, one S-video, and one component. Both PIPs feature window effects and freeze control.
PIP 422 and PIP 444 Picture-in-Picture Processors 2 Chapter Two Installation Mounting the Processor Rear Panel Connections Setting Up Genlock and Vertical Interval Switching
Installation, cont’d Installation Mounting the Processor The PIP 422 and PIP 444 are housed in 1U high, 17.4" wide metal enclosures that are rack- or desk-mountable. The appropriate rack/desk mounting kit (#70-077-03) is included with the processor. The processor may also be surface-mounted under a table, desk, or podium, or on a wall, using an optional Extron 1U enclosure under-desk mounting kit (#70-222-01).
Mounting Screws (2 Plcs) Each Side Supplied Rack Mounting Bracket or #8 Screw (4 Plcs) Each Side Optional Furniture Mounting Bracket Figure 2-1 — Mounting a PIP 3. Insert the processor into the rack, align the holes in the mounting bracket with those of the rack. 4. Secure the processor to the rack using the supplied machine screws. Table or wall mounting The table/wall mounting brackets extend approximately 1/4" (6.4 mm) above the top surface of the processor enclosure.
Installation, cont’d Through-desk mounting Mount the PIP through a desk or podium as follows: 1. Remove the feet from the underside of the PIP, if installed. 2. Attach the supplied mounting brackets to the processor with the machine screws provided (figure 2-1). 3. Cut the proper sized hole in the mounting surface (figure 2-2). Figure 2-2 — Through desk mounting a PIP 2-4 4. Hold the processor with the attached brackets against the underside of the table or other furniture.

Installation, cont’d 3 Input loop-through (bottom) connectors — If desired, connect local monitors to these female BNC connectors. The processor buffers the video input and loops it out on these connectors. The processor does not alter the video signal between the input and the buffered loop-through in any way. The processor’s buffered loop-through output is in the same format as the input.
Setting Up Genlock and Vertical Interval Switching For vertical interval switching (to allow clean switching between signals from several devices during the vertical blanking period of each signal), a composite sync signal can be applied at the Genlock In connector, and also passed to another device via the Genlock Out connector. If the genlock connectors are used only for vertical interval switching, no horizontal or subcarrier phase adjustments are required.
Installation, cont’d 8. View the horizontal phases again. If the phase difference is not zero, repeat steps 6 and 7 until the settings do not change. 9. Once the settings are stable, disconnect the oscilloscope, and reconnect the genlock cables. 10. Check the display(s) for proper colors and for undesirable artifacts in the image(s). Make adjustments as necessary. 11. If other PIPs are part of this genlock daisy chain, connect the oscilloscope to each device, and repeat this procedure.
