Abstract:

The DTAGS telemetry system consists of the following assemblies 1 PCM Uplink Encoder, 2 FSK Downlink Control, and 3 Cable Interface. The PCM Uplink Encoder includes the following towfish printed circuit boards 1 Analog Interface, 2 Analog Mux, 3 Floating Point Amplifier, 4 PCM Mux and control, 5 PCM Submux, 6 Shield Board, and 7 Motherboard. The motherboard includes space for 8 GFE printed circuit boards. Also, a part of the PCM Uplink assembly was the towfish encoder chassis and a single channel digital to analog converter to be located topside. The FSK Downlink Control assembly included the FSK Encoder, located topside, and the following printed circuit boards located in the towfish 1 FSK Decoder - 1, and 2 FSK Decoder - 2. The Cable Interface included the following towfish printed circuit boards 1 PCM Driver, and 2 Power Isolator. Also included is a topside cable interface and equalizer which provides power isolation, separates uplink and downlink signals on the cable, and equalizes the attenuation characteristics of the cable.
