Introduction The S-Video Switch 8 to 1 (AC041A) Your Video Switch package consists and Composite Switch 8 to 1 of the following: (AC042A) are designed for maxi- mum flexibility and economy. The • Video Switch unit Video Switches feature roll-free, • P6 Remote Control Unit vertical interval switching controlled • 25-foot remote control cable by a wired, electronic remote control with modular plugs which selects from up to 8 inputs • 9 VDC 500 MA plug-mounted (2 on the front panel, 6 on the transformer rear panel). • User Manual The AC041A is a 30-MHz S-Video (Y/C) switch for S-VHS, ED-BETA, Hi-8, and other video applications which use the 4-pin mini-DIN connectors. The AC042A is a 30 MHz Composite Video switch with BNC connectors. The single-digit, front-panel LED indicates the selected channel or flashes when there is no attached video input. Features include: • 30 MHz bandwidth • 8-button illuminated, wired remote control • 1000-foot range on the remote unit • Vertical interval switching • Unity gain • Table-top or rack mounting • Single-digit LED to indicate selected channel 3 P6 REMOTE CONTROL 1 5 2 6 3 7 4 8 Video Swithes 8 to 1 3.

For a permanent instal- lation, you may want to use an optional rackmount tray (RM001 or RM002). You can place up to two (2) units side by side on the tray. In a table-top installation, a minimum of 3 inches (7.6 cm) is required behind the unit in order to connect the input signals and the output signal to your monitor. With multiple video sources, you may want to consider placing your Video Switch as close as possible to the video sources in order to conserve wire. 3.2 Remote Control (P6) Connection To connect the P6 remote control unit, first insert the modular plug (RJ-11) of the 25-foot cord into the plug on the P6 remote (see Figure 1). Connect the other end of the cord to the rear-panel, female RJ-11 connector on the Video Switch (see Figure 2). Make sure the Figure 1.
