I corrected the lnb.c files in both scan-s2 and szap-s2. I'm able to lock, and the scan has produced a channels.conf file. I will run more to see if results are consistent.

I've been running both szap-s2 and scan-s2 all evening, and I get variable results! Sometimes it will lock, sometimes not. Once I even got a scan with data in my channels.conf file. The next time it fails all scans! I'm not seeing any stability here. Something must be wrong - My experience...

Has anybody gotten scan-s2 to work successfully with the prof 7500? I need some comparison points here - maybe I expect results that can't happen? I need to build a channels.conf file for Mythtv. Thanks

Interesting... When running scan-s2 I have also run with the -5 option, which increases the time (Tho I'm not sure it increases the CORRECT time) per channel. At this point I'm just supplying one known working set of numbers and it still can't seem to return anything useful. See post #35 above...

OK, I got a fresh set of files from mercurial for scan-s2, fixed the API check (to 5.1) and it is installed. I still can't get good results, using the prof7500. Tune-s2 works great, get lock. What is up with scan-s2? Does this need to be modified to work with the prof? Here is what I get with...

I had a problem with scan-s2 from mercurial. I didn't look at the source, though. I got your demux program, but I haven't installed it yet. Can you think of any reason the assignments of the prof and the TBS card might change around after reboot? Or, is there a way to ensure persistence of...

Heh, the compiler barfed, complaining because the S2 API was not 5.0 (It is 5.1). So I didn't pursue that any farther. Maybe I pulled an old set of files?? I'm pretty sure I built both scan-s2 and szap-s2 from the TBS files. I can't get a sucessful scan, but I'm sure I'm doing something wrong...

Tune-s2 has been running almost 24 hours, the prof has lock and no problems. What app can I use to check the video?

updatelee, I just realized you were talking about scan-2, not the dvb-s2 files. I'm not sure where the scan-s2 came from, probably either the TBS or dvb-apps. I'll get scan-s2 from mercurial and try that.

That is correct. I'm going to just focus on the prof7500 because the devices change assignments every time I reboot or make any changes. I wanted more than one tuner to handle both sat and local OTA HD TV antenna stuff. I didn't know if there were any other files needed for the prof. Thanks...

updatelee, can you tell me which files are needed for the prof7500? I just killed it by rebuilding the modules. ARRGH!

It sure does! tune-s2 12060 H 26700 -adapter 2 -lnb STANDARD LNB: low: 10750 high: 0 switch: 0 opening: /dev/dvb/adapter2/frontend0 LOW band Tuneing specs: System: DVB-S Frequency: 12060 H 26700 22khz: OFF Modulation: QPSK FEC: AUTO Inversion: AUTO Rolloff: AUTO...

Eh, ya caught me! I've gotten confused more than once... The TBS card is dual, it maps to Adapter0 Adapter2 The Prof shows up at Adapter1 Yet Mythbackend identifies them differently, in different order. Doesn't matter as all scans fail with myth anyway. Clear as mud?:D

updatelee, I ran tune-s2, and the TBS card appears to tune just fine: tune-s2 12060 H 26700 -adapter 2 -lnb STANDARD LNB: low: 10750 high: 0 switch: 0 opening: /dev/dvb/adapter2/frontend0 LOW band Tuneing specs: System: DVB-S Frequency: 12060 H 26700 22khz: OFF Modulation: QPSK...

The TBS 6981 using szap-2: szap-s2 -c channels.conf -p -r -S 0 "HEST" -l 10750,10750,11700 -a2 reading channels from file 'channels.conf' zapping to 1 'HEST': delivery DVB-S, modulation QPSK sat 0, frequency 12060 MHz H, symbolrate 26700000, coderate auto, rolloff 0.35 vpid 0x04ba, apid 0x04b0...

All right, I found a working syntax, but the tuning failed: scan-s2 -X -a 1 -f 0 -l 10750,10750,0 -o zap 'ses1-101w' > newchannels.conf API major 5, minor 1 ERROR: Cannot open rotor configuration file 'rotor.conf'. scanning ses1-101w using '/dev/dvb/adapter1/frontend0' and...

I think the TBS card is cx23885-based: [ 12.672121] cx23885 driver version 0.0.2 loaded [ 12.672527] cx23885 0000:04:00.0: PCI INT A -> Link[LN3A] -> GSI 19 (level, low) -> IRQ 19 [ 12.672565] CORE cx23885[0]: subsystem: 6981:8888, board: TurboSight TBS 6981 [card=29,autodetected] [...

Running szap-s2: szap-s2 -c channels.conf -S 0 "HEST" -l 10750,10750,11700 -a1 I see this on the terminal: status 1e | signal df08 | snr ea00 | ber 00000000 | unc 00000000 | FE_HAS_LOCK I assume this is a good thing! dmesg shows: [ 9807.156044] stv0900_get_rf_level [ 9807.196032]...

OK now, keeping in mind I'm totally NOOB here: Trying to tune one channel, SES-1@101W, 12060 H 26700, which is History E. although it scans as enc test 11 or somesuch with the DSR200. The TBS card is at /dev/dvb/adapter1/frontend0 The Prof7500 is at /dev/dvb/adapter2/frontend0 The sat cable...

I got started in this adventure by buying a Geosatpro dish, lnb, and DSR200 receiver. My intent has been to incorporate the sat into Mythtv so I could have a "convenient" mix of media. My assumption was that I could use the receiver to help get the dish set up and peaked, find some viewable...

A little more tinkering with menuconfig got the TBS card initialized OK as well: [ 12.672121] cx23885 driver version 0.0.2 loaded [ 12.672527] cx23885 0000:04:00.0: PCI INT A -> Link[LN3A] -> GSI 19 (level, low) -> IRQ 19 [ 12.672565] CORE cx23885[0]: subsystem: 6981:8888, board...

Looking at dmesg, appeard the prof 7500 is being detected and initialized OK. The TBS card is having some issues: [ 11.344685] Linux video capture interface: v2.00 [ 11.348834] cx23885: disagrees about version of symbol v4l2_i2c_new_subdev_cfg [ 11.348837] cx23885: Unknown symbol...

http://www.buydvb.net/download2/TBS6981/linux-s2api-tbs6981_v1.92.2.rar I didn't know if the board would allow URL... Modinfo shows the kernel module is proprietary to Turbosight. Maybe I answered my own question.. However the system is not loading this module, so I borked something. I know...

I have 3 sets of files: from Liplianin, from TBS, and now fromlinuxtv/ v4l-dvb. The TBS driver files are not in the distribution at v4l-dvb. I assume they were added by the manufacturer, which means they might show up at a later date in one of the other packages, but who knows? I'm working...

I am working on both the prof7500 USB DVB and the Turbosight TBS6981 DVB PCIe card. I am using the S2-Liplianin driver files for the Prof7500, and a modified version for the TBS card. Right now only the prof7500 is responding, the TBS module does not load as it should. I don't know if the...
