Start with the basics.
TS2 should have told you a line of text comprising all the configuration parameters. Have you loaded this successfully ?
TS2 should have told you what satellite and nominal polarisation to receive. What nominal polarisation have you been told to receive?
Use dish pointing iraq to find your polarisation adjustment angle, beam elevation angle and compass azimuth.
Connect the small LNB module to the LinkStar modem receive input. WARNING: You must never get the coax cables crossed over as this will permanently damage the modem.
First set the nominal feed polarisation. Vertical means that the broad faces of the LNB rectangular waveguide are on top and underneath. Do it. If the LNB is on a side arm, the arm is probably now sticking out at one side or the other.
Second, apply the polarisation adjustment angle. A positive adjustment angle requires a clockwise movement, while facing towards the satellite.
Set the beam elevation using the elevation scale on the bracket behind the dish.
Swing the dish boldly sideways around the approx compass azimuth and the RX LED will lock up on the satellite on the first sweep, unless the dish is sagging down a bit in which case add a couple of elevation degrees. Initially it will go to slow green flashing.
Spend at least 30 minutes peaking up. The centre is half way between the points where the LED drops out.
As you tighten the antenna, keep readjusting to the peak. Read the QPSK BER by typing tcmp at least 30 times (possibly 50 times !). Get it down below 0.00009 if you can.
Power off at the mains and connect up the TX cable. RX LED will go slow flashing green, fast flashing green and solid green. Don't interrupt this process. Talk to the hub while they test your x-pol. You may have to get yourself under the feed arm and reach up to rotate your feed polarisation a degree or two either way. Be patient between movements; it takes the hub time to test for your x-pol null.
Your modem will reboot and end up with new gateway IP address and subnet mask, as told to you by TS2.
Best regards, Eric.
