As a  pre-cursor to a new releasse of the full TVSource DVBLogic have issued a version of their DVBLInk TVSource Preview App which supports the Diseqc 1.1 and 1.2 standards. For those of you who haven’t seen it before the TVSource Preview app is a way of checking that the DVBLink software will be able to use your tuner without actually having to install the whole DVBLink suite.

For a long while Satellite users on the DVBLogic forums have been bemoaning the lack of control over their dishes that DVBLink gave. Diseqc is the stnadard method for controlling dishes and allows automating of such things as rotating dishes and choosing between multiple LNB’s (I’m not going to explain satellite technology here but – over simplifying – the LNB is the bit of the dish that actually receives the signal and you could possiibly have more than one in a physical dish) The prime cry from users has been for at least 1.2 support and to some extent DVBLogic have now answered that cry.

They have released for testing today TVSource Preview application with Diseqc 1.1 and 1.2 support.

Diseqc 1.1 is supported as a selection of up to 16 LNBs on a single uncommitted switch. The LNB selection is done via Diseqc dropdown box on Headends tab of TVSource preview.

Diseqc 1.2 is supported in the form of custom diseqc commands. Headend tab contains a button (Diseqc commands…) that invokes a command editor. Each command consists of a name and a unique string with HEX command bytes. Each command byte should consist of exactly two HEX characters (for example E0 10 38 F0). Command can be up to 16 bytes long and the string can contain spaces for improved readability. Once added, each custom diseqc command will appear in the Diseqc dropdown box of each headend.
This dialog also contains tuning timeout value that will be used by TVSource to wait for motor to turn the dish.

At the moment TVSource supports sending of raw diseqc commands for the following tuner brands and their clones:
AnySee, Hauppauge, Technotrend, Technisat, TeVii, TBS, Twinhan

DVBLogic would also like to ask you to run DebugView utility from Microsoft in parallel to TVSource Preview to see what is actually going on. It will greatly them to understand what is going on if the functionality will not work properly.

The TVSource Preview application with diseqc 1.1 and 1.2 support can be downloaded here:
