DiSEqC setting is not changing switch ports

[Phyxsius7]

OS: Windows 11
DVB-S2 PCI-E card:1x  TBS6982
Driver version 1.0.0.6
Diseqc Switch: 2x Venton 418-P
LNB: 3x ALPS twin
Software: DVBViewer Pro 
Software: DVBViewer Transedit 4.2.4.1

Setup:
TBS6982 card has 2 tuners, both tuners have there own DiSEqC Switch (Venton 418-P) and each Switch is connected to 3 LNB's (ALPS twin LNB)

 

Problem:
Trasnedit and DVBViewer Pro are not generating the correct DiSEqC command so that the Diseqc Switch would switch ports. 

 

Test hardware setup:
I simplified my setup for testing purpaces and did the following tests to confirm my suspision:
Connected only to 1 tuner (tuner port B) to 1 switch, connected that switch to 2 LNB's (Input A & B of the switch)
A to Sat 23.5
B to Sat 19.2

 

Test software setup:
Using the software Transedit locally and without DVBViewer media.
I added both tuners in Transedit > settings > hardware where all groups (A to H) are selected and tuner A is disabled.
Added transponder list for 19.2 and 23.5 and both are set to group A.
The DiSEqC settings are set as following and apllied and saved:
23.5 > Pos A/Opt A
19.2 > Pos B/Opt A

 

Testing:
1#
Within transponder list 23.5 I select frequency 12363 (free to air) and I "Scan selected", positive result 
Within transponder list 19.2 I select frequency 11347 (free to air) and I "Scan selected", negative result 

 

2#
Keeping everything as discribed in "Test software setup", the same 
I only change DiSEqC to Pos B/Opt A, apply and save and I "Scan selected" with positive result.
then
change DiSEqC to Pos A/Opt B, apply and save and I "Scan selected" with positive result.
then
change DiSEqC to Pos B/Opt B, apply and save and I "Scan selected" with positive result.
>> It seems that it does not matter what the DiSEqC is set to it always end up on port A of the switch.

 

3#
from here on I disconnect cable from the switch that leads to LNB Sat 19.2 and moved the cable that leads to LNB Sat 23.5 from input A to input B othen Switch and change DiSEqC settings in Transedit software accordingly and selected apply and save;
So to some up:
Switch port A = not connected
Switch port B = connected to LNB Sat 23.5 and with DiSEqC settings Pos B/Opt A
Within transponder list 23.5 I select frequency 12363 (free air) and I "Scan selected", negative result
Negative result is also true with any other DiSEqC setting with this setup

 

4#
I switch to the second Diseqc Switch with same results.
I both a brand new Diseqc Switch and repeated the test process with same results.

 

5#
I contacted TBS (maker of the DVB-S2 PCI-E card).
With their help we could reproduce the issue.
But when using two other software packeges (DVB Dream & TSreaderpro) there where no problem switching between the Diseqc Switch ports.

 

So, I could use some help finding out why DVBViewer and Transedit doesn't sen the correct commands to make the Diseqc Switch change ports.

Please perform the following steps:

• In TransEdit select Info -> Configuration Folder (opens an Explorer Window).
• Close TransEdit.
• Open the file TransEdit.ini from the configuration folder with a text editor (Notepad) and search the [Hardware] section.
• Make sure that for each TBS tuner there is a Vendor.x=31 entry (where x is the tuner number 0, 1, 2...). If the vendor code is not 31 (= TBS), correct it and attach your TransEdit.ini here.
• For each DVB-S tuner there is a line DiSEqCCount.x=1. It specifies how often DiSEqC commands are sent. Increase these values to 2 or even 3 for one or two repetitions.
• Save the changes, relaunch TransEdit and try...

DiSEqC only works if the device has been detected correctly as TBS, because it requires a TBS-specific handling. Additionally there may be a timing issue. TBS devices switch the LNB power off when they are not used. When a scan starts, the power is switched on. However, a subsequent DiSEqC command may be sent too early, before the voltage has reached a stable state or the switch has completed its power-up procedure, so that the command gets lost. Repeating the DiSEqC command usually fixes this issue.

 

For DVBViewer it can be handled in a similar way by editing the file hardware.xml in the configuration folder. I think you will see what has to be done without further explanation.

Many Thanks Griga,

Clear instructions and with great success, I have applied it to Transedit, DVBViewer Pro and finally to DVBViewer media which made it possible for Transedit and DVBViewer Pro to connect remotely.

It is still a mystery why it work for years without issues, could a software and/or driver update be the cause? Also the whole debacle resulted in wasted time and money (new switch and cables)

I have the same problem, upgraded from windows 10 to 11 (fresh install and can't switch back to the old configurations) and now DVBViewer  won't scan satellites via diseq1.1 and 1X8 switch beside the one attached to port 1. I mean it finds same signal and channels on all ports from port 1. I have these satellites attached on diseq switch: 
Port 1 - 4W

Port 2 - 0.8W

Port 3 - 9E

Port 4 - 13E

Port 5 - 16E

Port 6 - 19.2E

Port 7 - 23.5E

Port 8 - 36E

I set all ports uncommitted switch everyone of them set separately from 1 to 16 inserted, applied, scanned and so on but on every port I scan I only get signal from 4W and it only scans the cannels from there.
My DVB card is Tevii S464 and using DVBVier 5.0.0 which worked fine including switching ports via diseq switch on windows 10 but now on 11 it won't do it anymore no matter what I do. Not tested to see if it works on 10 anymore yet but i am tended to do it soon. Any idea what is the problem, is it the driver or any DVBViewer setting that i forget to do it? I tried every driver for Tevii DVB card from 5.1.3.0 to 5.1.9.3 with same results. Thank you in advance for any advice.

Please attach the (zipped) hardware.xml from your DVBViewer configuration folder.

Your hardware settings are ok, your DVB device has correctly been recognized as TeVii, so the TeVii-specific DiSEqC code in DVBViewer should work.

 

The only reason I can think of are timining issues. I would try to change the DiSEqCCount value in the hardware.xml from 1 to 2 or even 3. This lets DVBViewer send the DiSEqC command repeatedly. Please note that DVBViewer must be closed while changing the hardware.xml with a text editor (Notepad or such).

Did that too, replaced  <entry name="DiSEqCCount">1</entry> with  <entry name="DiSEqCCount">2</entry> then with  <entry name="DiSEqCCount">3</entry> copied the same hardware.xml in both c:/Program Files(x86)/DVBViewer and C/:Program Data/ CMUV and still same result. it only scans 4W, no matter which satellite or port I choose. And it finds only the 4W channels on every satellite or port I scan.

Did you perform a Windows 10 -> 11 upgrade installation, where your applications and their configuration remained unchanged, or did you perform a clean install from scratch, including a new DVBViewer installation?

 

Please also provide the file DiSEqC.xml from the configuration folder as attachment.

 

BTW: It would be nice if you could avoid full quoting of the complete previous post every time, which creates a lot of useless text. If you want to refer to a certain part of a previous post, use the mouse to select it and click on the "Quote selection" pop-up, like I did it above.

Sorry for quoting, will try to avoid this in the future. I did a clean install of Windows 11 after formatting the SSD entirely and also reinstalled the DVBViewer from scratch.

Port 1 - 4W

Port 2 - 0.8W

Port 3 - 9E

Port 4 - 13E

Port 5 - 16E

Port 6 - 19.2E

Port 7 - 23.5E

Port 8 - 36E

 

This doesn't match the DiSEqC.xml content:

• The 4W command is a positioner (motorised dish) command, not a command for an uncommitted switch.
• For 13E there is a command sequence that first selects port 1 and then port 4.
• The entry for 19.2E is missing.

The other positions should work, though. The according DiSEqC.xml entries are correct. Please note that you have to set DiSEqC to "Extended" in DVBViewer for letting it use the DiSEqC 1.1 commands in the DiSEqC.xml. Additionally the transponder list INI files used for scanning must contain a correct orbital position information.

 

I would rather use the DVB scanner & analyzer tool TransEdit (download from the customers area, read the ReadMe!) for DiSEqC setup and scanning, because it makes the settings you are working with more obvious.

I scanned with Transedit and same results, only port 1 signal on all ports, so it must be the incompatibility with the Tevii drivers on windows 11 I guess since it worked fine on windows 10. Not sure it is still working on windows 10 anymore since I don't have it now, but as soon as I get an empty SSD I will try and see.
