DAC-2202 Antenna Control Unit Operation
2-11
CONTROL
TRACKING OFF C
Press the
ENTER
key once to display the
Status – Control Tracking sub-menu
.
This is the display of the current Tracking and Band Selection information.
To turn the Tracking status On or Off, press the Track key, or press the RIGHT
arrow to bring up a cursor under the current tracking condition and then Press the
UP arrow to toggle status ON/OFF. Press Enter to exit the selection mode.
To toggle the Tracking band selection, Press the RIGHT or LEFT arrow and then
press the DOWN arrow to toggle through the list of possible BAND selections (i.e.
KuLo, KuHi, DLA or DSS
). The actual band selections available are dependent on
the parameter value entered for TRACK DISP. Press
ENTER
to submit and exit the
selection entry mode.
Band selection controls the local logic output state of SW1 output terminal on the
25 pin Terminal Mounting Strip PCB and if configured, remote C/Ku relays on the
antenna pedestal. When KuHi/DSS band is selected the SW1 output will be
shorted to ground (current sink of 0.5 amps max or when KuLo/DLA band is
selected the SW1 output is open (floating).) to control (but not limited to):

Band selection tone generators

Coax switches.
If AZ Limits have been set to define a known blockage zone “ BLOCKED ” will
appear in place of ON/OFF tracking status when the antenna is in the described
blockage zone(s). This Tracking condition controls the
local
logic output state of
SW2
output terminal on the 25 pin Terminal Mounting Strip PCB.
If the Antenna Pedestal, during normal operation fails to meet FCC stabilization
compliance “
MUTE ” will be appear in the place of the ON/OFF tracking status
Whenever in the “BLOCKED” or “MUTE” tracking condition, the SW2 output will be
shorted (or open, if SYSTEM TYPE is set to reverse this logic state) to ground,
providing a current sink of 0.5 amps
max , to control (but not limited to):

Below decks dual antenna coax switches

TX inhibit control to a satellite modem for radiation hazard control

TX mute for FCC compliance.
To test the blockage output, press the RIGHT arrow key 5 times (to bring up and
move the cursor to the far right). Press the UP arrow to simulate BLOCKED
condition and short (or open, if SYSTEM TYPE is set to reverse this logic state) on
SW2. Press the LEFT arrow key twice and then press the
UP arrow key to turn the
BLOCKED condition OFF and open (or short, if SYSTEM TYPE is set to reverse this
logic state) on
SW2
.
CONTROL
SEARCH 2 OFF
Press DOWN arrow or ENTER to access the Control Status – Search sub
menu.
This is a display of the current Search condition.
To initiate an automated SEARCH, press the RIGHT arrow to bring up a cursor
under the current Search status, and then press the UP arrow.
To terminate a SEARCH in process, press the RIGHT arrow to bring up a cursor
under the current Search status, and then press the DOWN arrow or press the
TRACK key
Press Enter to exit the Search Control mode.
