must be turned OFF
Antenna and Feed Assembly
Incoming signals from the satellite are int ercepted by the antenna
reflector ("dish") and focused into the feed assembly. The feed
assembly collects receive signals and passes them to the LNB.
The anten na geometry is termed an Offset Feed Parabola, with the
beam (satellite direction) typically orie nted 22.6
o
above a line
perpendicular to the antenna face, as shown above. The antenna
mount allows the antenna to be pointed toward the satellite by pivoting
around the mounting mast (azimuth) and by tilting about the mounting
head (elevation). The entire Antenna Assembly can be rotated about
the feed axis to set polarization.
Note that it is not a rule that an antenna offset is 22.6
o
. Refer to the
documentation that accompanies the antenna for the actual offset
specification.
LNB
The LNB provides the low noise amplification and down conversion
from Ku - band or C - band to L - Band. The down converted signals are
then routed to the RCST via coaxial cable. Based on the satellite
downlink frequency bands, the LNB is available to receive the
frequencies as spe cified below.

BUC
The BUC (Block up converter) accepts transmit signals from the
RCST and provides up conversion to the satellite uplink frequency and
transmits them to the satellite .
For the StarPro1 ODU, the BUC includes a Solid State Power Amplifier available as Ku- Band
transceivers for .5 - , 1 - , 2 - , or 4 - Watt operation and as C - Band transceivers for 2 - and 5- Watt
operation. The RCST provides a 24VDC source to power these units. For the 4- Watt Ku - ba nd
and 5 - Watt C - band units, the RCST is equipped with an external power supply adapter to satisfy
the additional power requirement.

Return Channel Satellite Terminal (RCST)
The StarPro1 RC ST combines a DVB receiver, a burst MF - TDMA modulator, and a terrestrial
traffic interface on a single integrated circuit board.

InternetVSAT.com Proprietary
The RCST terrestrial interface is a standard 10/100BaseT. The TCP Acceleration processing
engine is built into the RCST soft ware. The maximum aggregate TCP data transmission rate for
each RCST is 10Mbps.
The RCST comes with L - Band IF interfaces and can be rack - mounted. Depending upon the
satellite link requirements, the StarPro1 RCST is deployable in VSATs ranging from sub - met er
0.96m/1 - Watt Ku - band units to 2.4m/. 5 - Watt C -

A rack mounted RCST must occupy 3U space where the top 2U space is left empty as to ensure
adequate cooling. Less space can cause overheating and failure of the terminal.
Similarly, a tabletop mounted RCST requi res the placement to be cool and well ventilated. No
other items may be resting on top of the unit to ensure adequate cooling.

IFL installation.
Cautions:
1. Ensure installation meets all applicable cable codes, including National Electrical Code
(NEC) and local requirements.
2. Do not pull IFL cables using center conductor of the coax. Cable insulation is foam;
pulling by center conductor will damage electrical performance. Use full grip only.
(1) Pull the IFL cables, using good installation practices . Leave 3
meters (10 feet) of cable beyond the antenna post for adequate
service loops. At the indoor end, allow adequate service loop for easy
access and service of the RCST.
(2) At the outdoor end, dress the IFL cables to the antenna mounting
post using one of the tie wraps (included in the installation kit)
positioned 30 cm (12 inches) from the bottom of the post.
(3) Terminate cable ends with connectors to mating connectors on
antenna feed assembly and RCST. Dress cable to the support arm,
using tie wra ps.
(4) Use standard self - fusing tape on all outdoor connections as to
ensure a watertight system. Approximately 3 of tape is required per
connection.
Antenna Pointing
Record the following site parameters as determined with GPS:

Star Pro IDU Installation
Before a terminal can be operational InternetVSAT must be informe d of certain parameters and
your GPS position then INTERNETVSAT can enable your terminal. You must email
INTERNETVSAT with the correct activation form 2 working days before installation of terminal to
enable INTERNETVSAT to program your system and respond with your Network IP address.
Please note that PAS1R activations make take slightly longer.
Computer specification and telnet window operation
300MHz & above should be good for video etc.
Network card essential
1) IP Address Calculation
To calculate the I P address from the Ethernet address use the Microsoft default calculator .
S elect view/scientific .
Convert the last two octets of the MAC address (labelled Eth Addr) on the reverse of the unit
and convert from HEX to DEC. For example 9C.D0 converts to 10 .0.156.208. 10.0 will always
complete the first 2 parts of the default IP address.
2) PC Configuration
Windows NT
From desktop right click on Network Neighborhood
Left click on Properties
Left click on Protocol flag
Highlight TCP/IP protocol
Left click o n Properties
Left click on Specify an IP address for pc
Then enter the IP address you converted in step 1) as your gateway, and the pc ip address will
be one up from that address. So for the 9C.D0, we have: -
IP 10.0. 156.209
Subnet Mask - 255.255.255.0
Ga teway 10.0.156.208

InternetVSAT.com Proprietary

Subnet Mask - 255.255.255.0
G ateway 10.0.156.208
Left click on OK for reboot
No use of proxy within Internet Explorer or Netscape .
3) StarPro1 Network T est
Connect PC to the Star Pro with cross over Ethernet cable , or with straight cable through hub,
router, etc.
Te st connection by going to Command line and typing
Ping 10.0.xx.xx (Where xx is your converted IP from step 1)
If you are connected you should ha ve a roundtrip time of around 10 ms to StarPro1 & back .
Troubleshooting: -
If you are unable to ping your box, then check that t he default IP address you converted is
correct, and that you have configured your network card correctly.
4) Star Pro Configuration

6) Alignment Confirmation
To check the receiver has locked to the correct carrier type in tcmp and confirm the following .
Also ensure that you have a m inimum of 0.000 1 QPSKBER reading. If not, please adjust your
dish until you reach at least this figure. Note that the more zeros after the decimal point, the
better your rx and tx signals will be.
Troubleshooting:
If the CarrierPhase is reading (!) LO CKED and the RSVIT is (!) LOCKED, then check your dish
pointing, and also your boot parameter configuration using the pconf command mentioned
above. Ensure also you have the correct polarity set, which is Horizontal RX.
If you are sure that the dish is poi nted correctly, then check your cables are securely connected
at both ends, and no water etc has got into the cables.
7. CW Test
This procedure is for enabling the RCST to transmit a CW carrier from the remote site.
Before starting this test, the PWR a nd ODU lights should be on, and the SAT light should
be flashing. If not, then consult the troubleshooting steps above.
1. The CW carrier is measured in the InternetVSAT / Hub office.
For this measurement, the RCST must transmit a CW signal over the satel lite. The
Transmit frequency is specified on the CW commands .
DO NOT TRANSMIT A CW CARRIER UNLESS TRANSMIT
AUTHORIZATION IS GIVEN BY INTERNETVSAT / HUB!

InternetVSAT.com Proprietary
2. Before transmitting the CW signal, the RCST must establish receive
Synchronization . After receive synchronization is established:
On The W1 Network please enter the following commands and ensure correct reply from box
do not enter final command until authorized to do so by InternetVSAT .

authorization to do so by the PanAmSat hub: -
cacsetcw - power - 26 - fr eq 974.2 - time 12000
4. The transmission of the CW carrier will terminate after the Time has expired. To
immediately stop transmission of the CW signal, enter hw . This will reboot the
RCST.
5. The RCST will restart acquisition and synchronization after en tering the hardware
reset command, hw .
6. You may be required to re - send these commands again at a higher or lower power level if the
CW test is not at an acceptable level. InternetVSAT will instruct you to do this if required.
7. Once an adequate power le vel has been achieved, you will be asked to enter save t xx
(where - xx is the power level to be set on your box), then enter the hw command to reset the
box.
Troubleshooting:
If InternetVSAT / Hub are unable to see th e carrier, please check that the CW commands you
have entered are correct for the network you are on, and if not enter the hw command and re-
enter the commands. Also verify that all of the installation and configuration steps above have
been checked and completed.
The SAT light in the termi nal should start blinking after approximately 20 seconds. Leave the
terminal running in this state for 5 minutes.
After reboot all the lights in the front of the terminal will become solid for a second and the
satellite light will start blinking afterwards.
After a short while, the sat light on the terminal should lock solid, and you will acquire the
net work IP address and subnet mask which you will have received from InternetVSAT prior to
installation.
Note:
The default address is only effective until the RCST becomes Transmit Acquired. Once
th e RCST is TX Synced, it receives its Network IP Address from the NMS and the default
address is no longer valid. To re -establish the default address, remove the TX/Rx cables
from the back of the terminal, and it will automatically reset to default.
