Question about a QAM modulator for a headend

[d00d3l]

Hello all, hopefully I am posting this in the right spot - I've seen numerous others post about their FTA headend's QAM modulators here so I figured I'd give it a go

I have a Scientific Atlanta D9477-1 MQAM modulator. I have a device which outputs a DVB-ASI signal, and I'd like to modulate it onto a digital QAM channel coming out of my micro-headend (yes, I am that much of a geek!)

Issue is, I can't seem to get it to do so. It says the encryption mode is PowerKey, and I have no clue how to turn it off. Countless tries in the serial console have led to nothing, yet at the same time I see many others here using this same modulator to put out clear QAM signals. I assume I'd also have to map the PID of the input to one of the 4 RF outputs. Does anyone know how I'd go about modulating the ASI input onto a clear channel, for my FTA headend? Any advice is well appreciated!

I don't use this device and I see nobody else has any knowledge of it or is willing to share knowledge. I expect that it is more of the former. There is a document on the Cisco web site that looks to define installation and operation of this device. Search for file name

It appears to me that it can answer your questions.

If the device could be had for a decent price, it looks like a great way to make your own mini headend with QAM channels.

Hope this helps someone.

What sat and TP are you trying to use? Are you sure it is Power Key and not PowerVue?
