A little less analogue, and a lot more crap.

From memory, 'E0 30 6B 00' is the centre position for the motor, it is not a 'go to 0 degrees / true south', and does not relate to a specific satellite.

The parameter byte ‘00’ (i.e. Satellite Position 0) is reserved as a “referenceposition” which is not valid for storing satellite position data. However, someapplications may require a specific command to Enable (Soft) Limits, so allMasters (i.e. Tuner-receiver/IRDs) should be capable of transmittingcommand ‘6A’ with a data byte ‘00’, either specifically as an “Enable Limits”user-command, or by allowing“Position 0” to be selected for the “StoreSatellite Position” installation command.

Hello,

Trust has designed and built this Lnb Changer for a satellite dish Laminas 180, Trust helped me a lot in assembling and adjusting the Lnb Changer and for many other things, I thank him again.

I increased the rotation of the disecq "rotor" to about 350 °

does Trust and trust1 are the same person ?
for Trust or anyone who know :
on diseqc motor , when we select "goto 0" does the motor go to 'mechanical south ' or on a preset position?
in some notice it s write "go to pos 0 with east/west buttons and press reset" , does this way erase limits ?
do i have to set them before anything else ?

At most boards my name is Trust , for some reason I could not register here with that name , so I used Trust1
When you select Go to zero or Reference , the rotor moves to a mechanical switch at the zero position .
At some rotors thats automaticly a reset , but has no effect on the limits you activated before

Mod. Note

I've checked the Members' list and the name "Trust" is not in use - would you like to change to that? If so, suggest you PM @Analoguesat or @rolfw :cool:


Edit: I see it's all sorted :)

trust or someone else ! Did you read firmware in rotor or positionner ?
On different view about Diseqc Motor internal pictures its seems it’s the same chip!!
I tried to read the holtek 48r50 but unsuccessfully.
i am curious to see how they have managed diseqc command .

I dont have the equipment to read those chips , just use a old Maxplus 2100 receiver to control my lnb revolver

thanks Trust !
i know very well all the basic diseqc command , in case of rotor (lnb changer) there is very few informations about gotox.x command :
as i see on my receiver it s different from eutelsat datasheet ! (eutelsat says "Command byte ‘6E’ is not yet fully defined" !!
about lnb changer Cardiff said to me he had removed the limit switch and limits are not managed anymore.

i had put another question on this thread:

...about gotox.x command :
as i see on my receiver it s different from eutelsat datasheet !

There are indeed two types of GotoX commands.
Tested in this thread: USALS/ GotoX; Raw diseqc commands
Or in the parallel dutch thread: USALS/ GotoX, Raw diseqc commands

Copied from satelliteguys:
The GotoX command always starts with E0 31 6E ..,
....
in the dvbdream program I notice that two different ways are used to turn left or right from zero, for different diseqc motors:

motor:_______________________to the left (+ no. degrees)____________to the right (+ no. degrees)
STAB and SM3D12____________Ex xx_______________________________Dx xx
SG2100_______________________Ex xx_______________________________0x xx
Geotrack H120 and generic____Fx xx (counting back from FF FF)____0x xx
(For the test results: see the links...)

greetz,
A33
