Occasional counts are acceptable but more than 10 per minute indicates a problem that needs attention (refer to Troubleshooting section).
DAC-2202 Antenna Control Unit Operation antenna, by referencing timing pulses issued by the PCU in each of the 4 quadrants (defined by DishScan Phase), to determine where the strongest signal level is and will issue the appropriate Azimuth and/or Elevation steps to the antenna, as needed, 60 times per minute towards that quadrant. Both DishScan Phase timing mark and Amplitude drive are adjustable by the N7xxxx Remote Command parameter.
Operation DAC-2202 Antenna Control Unit SEARCH LIMIT – initially set to the default value. After targeting has been optimized (refer to Ch 5 in your antenna manual), the search limit can be adjusted if desired. SEARCH DELAY – default, or any number of seconds from 1-255 that you would prefer that the ACU wait before starting an automatic search. SWEEP INC – default value (this parameter is not used in this search pattern). GYRO TYPE – must NOT be set to zero.
DAC-2202 Antenna Control Unit Operation You can configure the ACU to do a special search pattern for a satellite that is in an inclined orbit by using the following settings: SEARCH INC - set to the default value for the frequency band that your antenna model is currently being used for (typically 10 or 20 counts). SEARCH LIMIT – leave this set to the default value for your antenna model.
Operation DAC-2202 Antenna Control Unit Target any satellite longitude value which includes even tenths digit values (ie SAT 101.0 W or SAT 101.2 W). If the desired satellite longitude includes an odd tenths digit, you must round it up, or down, one tenth to make the tenths digit EVEN. The Antenna Control Unit calculates the Azimuth, Elevation and Polarization values it will use to target the antenna. However, without heading input, the ACU cannot target a “true azimuth” position (relative to true North).
DAC-2202 Antenna Control Unit 3. Basic System Information Basic System Information This section provides you with some additional information about the satellites you will be using, some basics of your satellite antenna system and other equipment within your system configuration. For more information about you specific antenna, refer to its manual. 3.1. Satellite Basics The satellites are in orbit at an altitude of 22,754 miles (36,619 kilometers) and are positioned directly above the equator.
Basic System Information DAC-2202 Antenna Control Unit 3.1.4. Rain Fade Atmospheric conditions that may cause sufficient loss of signal level include rain, snow, heavy fog and some solar activities (sun spot and flare activity). The most common of these is referred to as “rain fade”. Rain drops in the atmosphere reduce the signal from the satellite. The heavier the rain the higher the amount of signal loss.
DAC-2202 Antenna Control Unit Basic System Information When you are at the same longitude as the satellite, its’ horizontal and vertical signals will be aligned to your local horizon. When you are east or west of the satellite, the signals will appear to be rotated clockwise or counter-clockwise from your local horizontal and vertical. Both horizontal and vertical signals from a satellite will appear to be rotated the same amount and are always perpendicular to each other.
Basic System Information DAC-2202 Antenna Control Unit 3.2.4. Antenna polarization If you have a circular polarization LNB installed, you do not need to adjust the “polarization” of the antenna. If you have a linear polarization LNB installed, the system should have been adjusted properly and set-up in Auto-Polarization mode. AutoPolarization makes small polarization adjustments periodically as the boat changes geographic locations by a significant amount of latitude and longitude.

Radiation Hazard and Blockage Mapping (AZ LIMIT parameters) The ACU can be programmed with relative azimuth sectors (zones) where blockage exists or where transmit power would endanger personnel who are frequently in that area. Your ACU software may allow you to set four zones or it may only three zones and include +5 volt polarization.
DAC-2202 Antenna Control Unit Setup When used as simple “BLOCKED” logic output for a single Sea Tel antenna, this output could be used to light a remote LED and/or sound a buzzer to alert someone that the antenna is blocked, and therefore signal is lost. In a “Dual Antenna” installation, this logic output(s) is used to control Dual Antenna Arbitrator panel of coax switch (or switches) to switch the source inputs to the matrix switch from Antenna “A” to Antenna “B”, and vice versa.
Setup DAC-2202 Antenna Control Unit 12 to 0500. If the antenna is between these two AZ Limit points but the elevation is greater than 50 degrees, the antenna will no longer be blocked. ZONE 2 begins (AZ LIMIT 3) at 82 degrees Relative and ends (AZ LIMIT 4) at 106 degrees Relative. Multiply these Relative positions by 10. Enter AZ LIMIT 3 value of 0820 and AZ LIMIT 4 value of 1060. In this case the Inmarsat antenna height only causes blockage up to an elevation of 12 degrees, so we set EL LIMIT 34 to 0120.
DAC-2202 Antenna Control Unit Setup ZONE 3 begins (AZ LIMIT 5) at 342 degrees Relative and ends (AZ LIMIT 6) at 348 degrees Relative. Multiply these Relative positions by 10. Enter AZ LIMIT 5 value of 3420 and AZ LIMIT 6 value of 3480. In this case the mast height only causes blockage up to an elevation of 41 degrees, so we set EL LIMIT 56 to 0410. If the antenna is between these two AZ Limit points but the elevation is greater than 12 degrees, the antenna will no longer be blocked. ZONE 4 is not needed.
Setup DAC-2202 Antenna Control Unit ZONE 2 begins (AZ LIMIT 3) at 352 degrees Relative and ends (AZ LIMIT 4) at 008 degrees Relative. Multiply these Relative positions by 10. Enter AZ LIMIT 3 value of 3520 and AZ LIMIT 4 value of 0080. In this case the mast height only causes blockage up to an elevation of 70 degrees, so we set EL LIMIT 34 to 0700. If the antenna is between these two AZ Limit points but the elevation is greater than 70 degrees, the antenna will no longer be blocked.
DAC-2202 Antenna Control Unit Setup Use the LEFT or RIGHT arrow key to move the cursor left or right to select other characters to modify. When you are finished modifying press ENTER to execute the new value OR press NEXT to abort and exit setup mode. 5.22.
