SeaTel DAC-2202天线控制单元 125411-3 REV W.02

The DAC-2202 Antenna Control Unit has been designed and manufactured so as to be inherently reliable, easy to maintain, and simple to operate. Except for start-ups, or changing operation with different transponders or satellites, the equipment essentially permits unattended operation. The DAC-2202 is housed in a standard 19 x 1.75 rack mount enclosure. The front panel contains function keys used to select the desired information to be displayed, and/or changed. Data is displayed on a 2 line 20 character display. All external connections are made through connectors mounted on the rear panel. The DAC-2202 automatically calculates the Elevation, Azimuth and Polarization pointing angles based on the ships Latitude, Longitude and the desired Satellite Longitude position. A programmable pattern search will automatically scan the area for a desired satellite if no signal is found. These two features make locating a new satellite very easy. The DAC-2202 requires satellite signal input to its internal Satellite ID Tracking Receiver to keep the antenna peaked on satellite. This internal receiver is a DVB compliant DSS compatible Satellite Identification receiver. Its input allows full coverage wide L-Band (950 to 2150 MHz) for tracking video transponders in all TVRO satellites and may be set to Single Channel Per Carrier (SCPC), or Narrow Band IF (NBIF) mode to allow tracking an L-BAND satellite beacon or narrow band data carrier.
