9711QOR-86 C & Ku-Band TXRX
Installation
3-39
[If you find the AGC reading for locked and unlocked conditions need to be reversed you
must add 128 to your current SYSTEM TYPE parameter].
Turn tracking OFF when checking the external AGC inputs. Be sure to properly retune the receiver
frequency when you are finished testing the external input.
•
Operation - In
NORMAL
operation, AGC must be above Threshold AND external MODEM
Lock input must be locked to Track the satellite. If you are tracking a satellite signal and the
AGC is above threshold (Tracking light on solid) but the external AGC signal rises above 2.5
volts for more than 20 seconds (external MODEM input UNLOCKED) the ACU will
automatically retarget the selected satellite.
SW1 - Band Selection control output. This output is used to control below decks tone
generator(s), or coax switch(s), for band selection functions. The band selection control output is
driven by the band selected in the MODE – TRACKING display.
SW2 - The Blockage
/
TX Mute Control output is driven by Blockage and RF Radiation Hazard
functions. This output will short to ground whenever the antenna is within the programmed AZ
LIMIT zone(s) or is Searching, Targeting or is mispointed 0.5 degrees from satellite peak. This
output is commonly used to drive:
If your modem cannot use the Modem Console Port connection you will have to
provide a transmit inhibit output from the ACU by connecting a SW2 wire connection
to the modem to comply with FCC Order 04-286 and WRC-03 Resolution 902.
•
Dual or Quad Antenna Arbitrator coax switches in dual antenna configurations. The coax
switches select which antenna is feeding signal to the below decks equipment.
•
Mute the Transmit output of the Satellite Modem used in TX/RX antenna configurations
when the antenna is positioned where people may be harmed by the transmit power
emanating from the antenna (RF Radiation Hazard).
•
Mute the Transmit output of the Satellite Modem used in TX/RX antenna configurations
when the antenna is mispointed by 0.5 degrees, or more, and keep it muted until the
antenna has been within 0.2 degrees of peak pointing to the satellite for a minimum of 5
seconds (FCC part 25.221 & 25.222 TX Mute requirement).
3.10.7.5.
TS2 Synchro Gyro Compass Input.
Use the R1, R2, S1,S2 and S3 screw terminals to connect the Synchro Gyro Compass to the ACU.
3.10.7.6.
TS3 Step-By-Step (SBS) Gyrocompass Input.
Use the COM, A, B and C screw terminals to connect the SBS Gyrocompass to the ACU. Some SBS
Gyro distribution boxes have terminals which are labeled S1, S2 & S3 instead of A, B and C.
3.10.7.7.
TS4 Power
•
VREG Screw terminal is used to provide a regulated DC operating voltage to ancillary
equipment. Voltage out is dependant upon which terminal mounting strip assembly is
provided. 126865-1 supplies 8Vdc @ 1Amp, while the 126865-2 assembly supplies 5Vdc
@ 2Amps.
•
GND Screw terminal is the ground reference for the regulated and unregulated power
terminals.
•
12/24 Screw terminal is commonly used to provide operating voltage to a external GPS,
Dual Antenna Arbitrator or other below decks tone generators or switches. Voltage output
is based on the T.M.S assemblies JP5 jumper settings.
3.10.7.8.
TS5 NMEA A/B, GPS output.
•
RxA- and RxA+- screw terminals, which are defined as the NMEA A connection is used to
connect to the ships Gyro Compass (Heading). The NMEA0183 compliant inputs are then
connected via a 9 pin ribbon cable to the ACU’s J2 NMEA communications port. A GPS
(Latitude and Longitude) input may also be connected, but is not required because there is
a GPS device already installed in your antenna.. NOTE:
If you connect a ships GPS to the
terminal mounting strip, you
MUST
disconnect the GPS antenna on the antenna
pedestal.
•
RxB- and RxB+ screw terminals, which are defined as the NMEA B connection is used to
connect to the ships Gyro Compass (Heading). The NMEA0183 compliant inputs are then
