Phyxsius7 Posted September 27, 2022 Share Posted September 27, 2022 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. Quote Link to comment
Griga Posted September 28, 2022 Share Posted September 28, 2022 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. Quote Link to comment
Phyxsius7 Posted September 28, 2022 Author Share Posted September 28, 2022 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) Quote Link to comment
