Digital Devices Octopus + Duoflex T2 -- no scan data

Added by Martin Bednar almost 6 years ago

Hi,

I have a DigitalDevices Duoflex T2 card, which gets recognized by the OS. However, neither tvheadend nor w_scan find any channels.
The cable is good -- a normal TV works just fine.
Anyone got a digitaldevices hardware working?

Gentoo, kernel 4.20.3.
I compiled and installed the linked driver.
Although this isn't a long term solution, since I also need to use a cx23885 card.
Still got no channels (w_scan)

edit: It seems i2c calls fail in general on these devices. I guess I'll check the power connector is connected correctly.

RE: Digital Devices Octopus + Duoflex T2 -- no scan data - Added by saen acro almost 6 years ago

Are you shure that you installed latest driver from git? (there is change 4 days ago)

ddbridge.conf
options ddbridge adapter_alloc=3 msi=0

RE: Digital Devices Octopus + Duoflex T2 -- no scan data - Added by Martin Bednar almost 6 years ago

Yes I'm sure. The version string in the dmesg output is a giveaway: 0.9.37. Which is the version bumped to a few days ago.
I already played around with the msi option, changed nothing. Will try fooling around with adapter_alloc.

RE: Digital Devices Octopus + Duoflex T2 -- no scan data - Added by Martin Bednar over 5 years ago

Necro posting to finalize this:

Per communication with digitaldevices support, their cards require a signal level of at least -44dBm for good reception.
I have no idea about the validity of the data reported by tvheadend, but on my installation I get a reported signal of -60dBm.

I switched to a TBS 6281SE, and on the same setup (and still a reported signal level of -60, I get an image).

I don't know whether the TBS includes an LNA, or the source of the difference, but here it is...
