menu.
Use the
AUX1
or
UP
arrow key to turn Tracking
ON/OFF.
Use the
DOWN
arrow key (two times within 3
seconds) to toggle the BAND selection ( Ku or
C/X ). Then use the DOWN arrow key once to
toggle between KuHi/KuLow OR C/X. Band
selection controls the
local logic output state of
SW1 output terminal on the 25 pin Terminal
Mounting Strip PCB and
remote C/Ku relays on
the antenna pedestal. When KuHi or X band is
selected the SW1 output will be shorted to
ground (current sink of 0.5 amps
max ) to control
below decks band selection tone generators or
coax switches. When KuLo or C is selected the
SW1 output is open (floating).
If AZ Limits have been set to represent relative
position(s) of the antenna that are blocked from
receiving satellite signal (Blockage Zone) or
where transmit must be disabled to protect
people who may congregate in the location of
the ship (RF Radiation Hazard –
TX/RX systems
ONLY ), “ BLOCKED ” will appear at the end of the
second line when the antenna is within in the
described blockage/hazard zone(s) [OR is
searching or targeting]. This function controls
the logic output state of SW2 output terminal on
the 25 pin Terminal Mounting Strip PCB. When
BLOCKED the SW2 output will be shorted to
ground (current sink of 0.5 amps
max ) to control
below decks dual antenna coax switches or TX
inhibit control to a satellite modem for radiation
hazard control or TX mute for FCC compliance.
To test the blockage output press the
5
key,
BLOCKED will appear on the second line of the
display and the SW2 output terminal will be
shorted to ground. Press the
UP arrow key to
turn the BLOCKED condition OFF and open SW2
contact to ground.
