About this file
This document is a technical schematic and specification drawing for a satellite television system installation on the NOAA Ship Thomas Jefferson. The drawing was prepared by Ritchard E. Conway on August 17, 2018, and consists of three pages detailing the SWM (Switched and Managed) assembly for DirecTV satellite television service.
The system design includes four SWM Tuner Modules (A, B, C, and D) that collectively support 32 tuners, with an SWM Expander component managing signal distribution across multiple deck levels (Above Deck, Main Deck, 2 Deck, and Below Deck). The configuration utilizes four satellite receivers (BBSAT1-A, BBSAT1-B, BBSAT2-A, BBSAT2-B, BBSAT2-C, and BBSAT02-A through BBSAT02-B) connected to an 8-way splitter and multiswitch components. Power inputs of 24VDC are provided at multiple distribution points. The system includes legacy ports and flex ports for signal routing, with voltage specifications of 13V and 18V at 22kHz frequencies. The schematic shows two distinct configurations: a normal HD configuration and an L.A. (Local Area) configuration that incorporates a 4X8 multiswitch for non-SWM compatibility. DirecTV LA receivers are specified for specific locations including the Lounge, Mess, and Deck 1 Voice/TV Box areas. Technical notes emphasize proper component selection to avoid signal attenuation and recommend HD splitters for HD systems when converting between configurations.
