FAO: Developers!! Zapit.Conf and SMW Switch band lnb

[BoSSpak]

I have a SMW X-line type E lnb with chapparal wideband ku polorator. I use a Drake ESR 2000XT analog receiver to drive the servo-motor to change the polarity(H/V).

With my nokia 9600s with dvb2000 setup switching between low to high band is working fine like a normal universial lnb functions but when using on a nokia dbox2 with Netutrino image and i can not seem to get the bands to switch. This what i have in the zapit.conf.

diseqcType=0
lastChannelRadio=23
lastChannelTV=4397
lastSatellitePosition=192
lnb0_OffsetLow=9750000
lnb0_OffsetHigh=10600000


I think i need an extra line in the zapit.conf so it has the switching frequency for bands to switch between each other correctly. I need to know the tag name so i can add the switching frequency 11700000

Thanx for the help

no you don't. The switching frequency is hardcoded in apps/dvb/zapit/src/zapost/frontend.cpp:608 as 11.7 GHz.

You probably need to recompile zapit with debug support to find out what is going one there.

Does it work with a standard setup? It could simply be a hardware defect...

EDIT: I have just read the specs of the X-line LNB. It does band switching by 14/18V (which is normally used for H/V switching), not via 22kHz tone. So you need to configure all your high band transponders to be on H and all the low band transponders to be on V (or the other way round) and it should work.

Good luck ;-)

Thanx seife for the tip m8, all working now well i only got to test on Thor 0.8W The rest i will do over the weekend.

At first i was editing my existing service.xml which had no effect on the switching of the bands not sure why?? in theory it should have worked anyhow then tryed editing the satellite.xml, a complete new search.. bingo!! it worked.
This is the method i used. (BTW I used Bouquet Wizard v3.0.3 to sort the channels in to groups in no time, kept all Verticals in one group and Horizontal in the other, makes sense and save the hassel)

LH = LowBand Horizontal
LV = LowBand Vertical
HH = HighBand Horizontal
HV = HighBand Vertical

<!-- H = 0 Low Band set to pol = 1 (13v) -->

So the standard in the satellite.xml is that Horizontal polarisation = 0 and Vertical = 1, but in our case our polarisation is by the external analog receiver so these polarisation value we use to switch our lnb band from lower to upper. so therefor 1 = LowBand which is 13v and 0 = HighBand which 19V. here is my extract of satellite.xml just for Thor 0.8W
