Long shot with TBS6909X card

[thatnewguy]

I'm trying to *receive* Diseqc data from my DS 2800 motor. I can send movement commands just fine, but I get nothing when I tried to query it for its current position. I think it has a STiD135 chip and that can't receive the results of the FE_DISEQC_RECV_SLAVE_REPLY command.
I think this is a failure of the card to receive, not a failure of the motor to send data.
Has anyone run into this - and if so, does anyone have a workaround?

Welcome to the forum, thatnewguy !


So, what diseqc motor is that?
I can find the DM2800 (diseqc 1.2) motor, not a DS2800 motor.
Added: And does that DS2800 motor support diseqc 2.2 (bidirectional diseqc)?

That is the 'typo' brand of motor.

It's a DM2800.

It doesn't say it supports 2.2 but when I connect my V8 Finder 2, it immediately moves the dish if it's not in the correct position. I assume it did that by querying the motor for current position. Valid assumption, or not?

Valid assumption, or not?

Alas, no. Normally a diseqc command is sent when you switch to a new channel (or (only) to a new satellite, when "fast diseqc" is ON). It does not first check, at what satellite position the motor is.
The receiver then expects that it gets a "lock" on the new channel.
If not, the diseqc command is repeated (the period of checking is very different for different receivers, I noticed).

That is how I've seen it work with diseqc switch commands. I assume it is similar with motor commands.

I do not know if a receiver gives an immediate diseqc command, after it notices that a current has started flowing (so: after connecting). That could very well be the case. I don't have an oscilloscope, alas...

Thank you! I was worried that was the case.
