A flashing ‘8’ indicates an Elevation Up command
A flashing ‘4’ indicates an Azimuth Down (CCW) command
A flashing ‘6’ indicates an Azimuth Up (CW) command
A flashing ‘0’ indicates No antenna drive command
10. Repeat steps 2-9 driving antenna the other 3 directions, (Replace Step 5 with below steps as each direction is
tested)
11. Using the LEFT arrow to drive antenna down (CCW) in Azimuth
12. Using the
DOWN
arrow key to drive antenna down in Elevation
13. Using the UP arrow key to drive antenna up in Elevation
If problems are encountered with tracking recovery refer to 123400_C DishScan® document available on our dealer
support site.
15.6. Blockage Simulation Test
Blockage output function is used to modify the behavior of Tracking and Searching when there is a known blockage
zone. The ACU provides a contact closure to ground on the SW2 terminal of the Terminal Mounting Strip when the
antenna is pointed within any one of the blockage/hazard zones or the system is searching, targeting, unwrapping or is
mis-pointed by 0.5 degrees or more (FCC TX Mute function for Transmit/Receive systems only). The contact closure
is a transistor switch with a current sinking capability of 0.5 Amp. This logic output control signal is used for:
•
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 signal is lost.
•
In a “Dual Antenna” installation, this logic output(s) is used to control Dual Antenna Arbitrator panel of coax
switches to switch the source inputs to the matrix switch from Antenna “A” to Antenna “B”, and vice versa.
•
When used as simple “ RF Radiation Hazard ” logic output for a single Sea Tel TX/RX antenna, this output
could be used to suppress RF transmissions while the antenna is pointed where people would be harmed by
the transmitted microwave RF power output. The SW2 output would be interfaced to the satellite modem to
disable the TX output signal from the Satellite TXRX Modem whenever the antenna is within the RF
Radiation Hazard zone(s).
•
When used for “
FCC TX Mute
” logic output for a single Sea Tel TX/RX antenna, this output could be used to
suppress RF transmissions whenever the antenna is mis-pointed 0.5 degrees or more, is blocked, searching,
targeting or unwrapping. The SW2 output would be interfaced to the satellite modem to disable/mute the
TX output signal from the Satellite TX/RX Modem. When the mute condition is due to antenna mis-pointing,
it will not un-mute until the pointing error of the antenna is within 0.2 degrees. The default output is
contact closure to ground when the antenna is mis-pointed, therefore provides a
ground
to “Mute” the
satellite modem on the SW2 terminal of the Terminal Mounting Strip. If your satellite modem requires an
open to “Mute”, refer to SYSTEM TYPE parameter 16 value to reverse the output logic from the ACU.
To Test the blockage function:
1. Press the NEXT key until you are at the Status menu. Press ENTER to access the Tracking menu.
2. Press the RIGHT arrow key to bring up and move the cursor to the far right. Press the UP arrow to simulate a
manual BLOCKED condition. BLOCKED will appear in the Tracking display.
3. Verify that SW2 terminal shorts to ground (or open circuit if you have SYSTEM TYPE configured to reverse
the output logic) and that the external alarms actuate OR the Dual Antenna Arbitrator coax switches toggle
(if antenna B is not blocked) OR the Satellite Modem TX is disabled/muted.
4. Press the LEFT arrow key and then press the UP arrow key to turn the simulated blocked condition OFF.
BLOCKED will disappear from the Tracking display.
5. Verify that SW2 terminal is open circuit (or ground if you have logic reversed) and that the external alarms
deactivate OR the Satellite Modem TX is un-muted. The Dual Antenna Arbitrator coax switches should not
toggle until you manually block Antenna B ACU.
15.7. Test Broadband Operation
Open your Internet Browser and access several internet sites, email or other functions as you normally would.
Operation should be the same as any equivalent service ashore (based on your subscription rate).
