I am using the dCSR-54 not the dcss-422. The dSCR-54 only has Sky frequencies (but was easier to install in my setup).
However I have been able to get this work by selecting userbands and frequencies from the dSCR-54 that the Gigablue box likes.
In my case I added a line for the dSCR-54 to unicable.xml as suggested by twol. So the Unitron-Johnson entry now reads:
Code:
<manufacturer name="Unitron-Johansson">
<product name="9732" format="dSCR" scrs="1210,1420,1680,2040,985,1050,1115,1275,1340,1485,1550,1615,1745,1810,1875,1940"/>
<product name="dSCR-54" format="dSCR" scrs="0000,0000,1680,0000,0000,0000,0000,0000,1280,0000,1380,0000,0000,1480,980,1030,1080,1130,1530,1580,1630,1730,1780,1830,1880,1930"/>
</manufacturer>
(the 0000 entries are to pad out the frequency array for userbands that the dSCR-65 doesn't offer).
However it is not necessary to do this. Add Tuner A using UB 3 from the 9732 Unitron-Johansson switch (per my original post), all subsequent tuners can be set up using:
HTML Code:
(Unicable/JESS) type = SCR (Unicable/JESS) User defined
which allows the Channel/userband and frequencies to be defined manually.
The frequencies which worked for me are:
Tuner A UB=3 Freq=1680
Tuner B UB=22 Freq=1730
Tuner C UB=24 Freq=1830
Tuner D UB=26 Freq=1930
Tuner E UB=25 Freq=1880
Tuner F UB=16 Freq=1030
Tuner G UB=19 Freq=1530
Tuner H UB=18 Freq=1130
I did a full scan of 28.2 frequencies after adding each tuner to verify. It can be terminated after a few seconds as it's obvious which frequencies work and which don't.
I don't know if other UBs/freqs will work. For "bad" UBs/frequencies I was getting tune failed which writes a zero duration file. With these settings I can get 8 simultaneous good recordings.
I've been stress testing over the last couple of days and this works reliably over multiple reboots and multiple timer records torture tests.
I thought this might be useful given that these switches are pretty ubiquitous and cheaply available on ebay. You will probably need to budget for a power supply. Mine would work powered from the quattro LNB inputs of my multiswitch, but I had the feeling it was on the edge (20v PSU fashioned from old lenovo PSU).
