BEV Multiport Switches vs. *Choice

I've just cancelled my Starchoice and I am now installing a 9200 system.

I had a 5x8 switch (Eagle Aspen S-4180GX+) with Starchoice.

Can I used the same switch with Expressvu if I connect all 4 feeds from the dish correctly?

It 'seems' that this switch uses both +18V/+13V and 22khz for signalling, but I'm unsure.

I could use the SW44 that comes with the 9200 system, however, I might want to feed more than 3 receivers.

Any guidance would be appreciated.
 
it should work........
follow the instructions exactly, or you will have issues
i have only seen 1 of the switches you were talking about, and it was defective, so i am not sure it will work
the 4x4 bell is gonna give you, will be able to power 2 additional boxes, on top of the 9200
ask the installer to try it (since the job is easy, being an ex *choice customer and all)
 
Your talking to the installer! ;)

I'm starting to understand the technology, just need to fully understand the switching. I would gather that it doesn't matter which I connect to Sat A or Sat B on the switch, as long as I'm consistant and don't mix the polarities.?

Just to confirm, I take 1 Even/18V and 1 Odd/13V from each LNBF (for the ExpressVu dish).

Starchoice had a Y-Type integrated Quad Multiswitch, and what I can tell from the diagram, the connection was slight different based on the conversation I had with the Starchoice installer.

Thanks.. this is tomorrows project.

I have no experience with this switch but I'd be very surprised if it worked, especially feeding more than 4 receivers. Over in the 9200 Installation 101 thread, no one has ever offered this as a solution to connecting more than 4 receivers (or any Bell receivers for that matter).

Don't forget that your receiver has to be able to identify the switch type, and I doubt this is a supported model, if it was even compatible.

I remember reading that *C and BEV lnb's do not work together. I don't remember why though.
 
This is not an LNB issue, it is a switching issue.

I'm using a BEV dual dish (4 feeds).

I'm going to align it with an SW44 first, and then see if I can get the 5x8 switch to work. The 5x8 is nice, as I can run an antenna or cable in on the 5th port.

The drawings that come with the 5x8 switch show the same setup as the SW44.
 
First, he's right, the LNB's are different, but the question is SWITCHING.

*C uses Voltage and Tone to select polarities and satellites.
Bev uses a proprietry switch, loosely based on DiSEQc.

The BEV receiver firmware must do a 'check switch' to determine what LNB's are connected to what port and what kind of switch.

Because of the intelligent nature of the switch and protocol, various cascaded combination are possible, but the *C swith is NOT one of them.

This is how Echostart is able to have 7 sats connected to a cascaded switch system.
For example, I run an SW64 with 148/110/119 on the 3 pairs of inputs, but then cascade in a sw21 with 61.5 on 1 of the outputs.
The DN6000 is able to scan the configuration and determine what is where.
This design puts Bell ahead of *c should they require a 3rd sat at a new orbital slot.

I beleive that to feed more than the # of outs a SW44 allows, would require a set of DTV3x4 multiswitches that will replicate the 2 ports of each LNB into 4 and then feed 2 sets of SW44's.

Alternatly, using DishPro Stacked LNB's and their associated switches would also be a neat solution.
Stacked LNB signals are the ONLY type of sat signals that can be truly split in the conventional way, but still reuire a supported multiswitch when dealing with multiple satellites.

So a pair of STACK LNB's into say a pair of 16 port splitters and 16 SW21's using a line from each would drive 16 lines/receivers.
 
*C LNB's are linearly polarized.
They receive signals that are either VERTICALy or HORIZONTALy polarized as is standard in all DTH/FSS satellites.

In Bev's case the signals are either RIGHT Hand or LEFT Hand CIRCULAR Polarized as is standard for all DBS (Dish, DTV) satellites.

For this reason, DBS alignments need only be concerned with Azimuth and Elevation, where as DTH must also include SKEW, the Vertical is only vertical when looking due South. East or West creates aslanted look angle at the satellite the the LNB must compensate for.

Of course SKEW also comes into play when dealing with more than 1 satellite since SKEW is created by the elevation differences of multiple sats.
