Hi,
I'm testing with scan-s2 and szap-s2 as described in the README_TBS6981, but I'm getting problems which I think are something to do with DiSEqC switching.
Firstly, it seems that the scan-s2 default output format (VDR) doesn't include the DiSEqC switch position (and szap-s2 has no option to specify switch position), so that subsequent attempts with szap-s2 always look on "sat 0" which fails with the other satellites. But if I add the "-o zap" option to the scan-s2 commands (and pass the shorter channel names to szap-s2), it looks on the correct switch position and I am able to get a lock from all four satellites.
However, the switching still seems to be intermittent... sometimes a zap will work and sometimes it won't. In particular switch positions 0 and 1 seem to get a lock every time, but switch positions 2 and 3 often fail. Sometimes I can get a lock when I CTRL-C and retry, sometimes I try a scan or I zap to another switch position first and then I can get a lock but not necessarily on the first attempt.
When the same cable is connected to an alternative set-top box (a Technomate TM-5000, I can't easily see the DiSEqC switch but I think it's a Technomate TM-4S) channels on all 4 satellites are received with no problems. For sure something isn't working between the TBS6981 and the DiSEqC switch but I don't know what.
I'd really appreciate some advice on diagnostics I can do to identify the problem and hopefully the solution.
Many thanks,
Nick
