Hi All,

Hopefully you can advise or point me in the right direction.

I have a TM2600 Super DiSEqC motor and wish to add a Televes ISD 830.

As you can see from the video on the dish manufacturers website the dish has a mounting bracket that is centered, so any motor arm would go to the left hand side of this (looking from the back).

I have never setup a DiSEqC motor but I believe that the motor arm and LNB should be aligned.
How do calculate or I achieve this with the above named equipment?

The link above mentions an offset angle but I assume this refers to the LNB angle to the dish face.
 
It's no different, as long as the dish is pointing due south when the motor is zeroed it will operate like a dish with a normal bracket. The elevation and declination angles are exactly the same. It just means the dish will be slightly higher on one side of the arc and lower on the other, but it will still follow the arc.

Thank you.

To avoid being slightly out, could I do some measurements from horizontal of the bracket and the vertical of motor arm from underneath and calculate the angle with some basic maths?
 
I'm not sure what you mean but you could check to see if the dish bracket is parallel to the motor bracket.

Most (but not all ) DiSEqC motors have a ridge on the shaft - oooerrr ! - and most (but not all) dish brackets have a hole through which the ridge of shaft can be seen and should be centred - ooooerrrr ! - but only when the dish face is removed.

Three things to look at.

1. The mounting pole or mast must be absolutely vertical as possible, left to right, front to back, if off one way it will affect the tracking.

2. The dish and motor must be at zero, any skew on the dish or LNB must be set to zero, then the dish and motor assembly is aligned to True South. (180 degrees true, or if you use a compass you must correct for magnetic deviation at your location)

3. Elevation, this must be set by a combination of the motor elevation and the dish elevation settings, this info should be in the motors instruction manual.

Once this is all done, you can find the nearest satellite to Due South from your location, this will be your go to zero satellite.
