Modem question
Hi all non car question sorry but im sure someone on here can help
I have seen one of these http://www.vaillant.co.uk/trade/products-t/controls-t/diagnostics-t/vrdialog-t/
In action lately and I'm pretty impressed.
Now the software is downloadable for free and i have the leads already so its just the black box that i need really
The one i have seen in action has a usb out, a adsl in and a ethernet port But has no details on the box.
Am i right in thinking the box is just a usb modem
like this http://www.edimax.co.uk/en/produce_detail.php?pd_id=216&pl1_id=2&pl2_id=11
Is it just a manufacturers tax they have put on it or would the box be unique to there product.
Possible saving of £80 if it is so fingers crossed
Thank you Adam

I can guarantee that it is not an ADSL modem! It will almost certainly be a proprietary interface and protocol.

Modem?
It looks like a Boiler Interface for Valiant Boilers.
So you can interrogate and read the fault codes.
A bit like an OBD reader for a Car ECU.
Comms related, in only as far as it connects your PC to a boiler to read the fault codes.
The only thing where ADSL or Ethernet comes into it, is so that it can be communicated with over the internet, ie remotely. Providing you have opened
the correct ports and protocols on the firewall (Needs the network set up properly to be able to route to it). Again to remotely access the Boiler for
diagnostic purposes.
I cant see why you would need one Unless you are a Heating Engineeer, or have a troublesome boiler!
Just my 2d's worth.
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

It's more likely that the unit is a rs485 to usb interface.
The vast majority of heating systems use rs485 to communicate and having had a quick look at the instructions it would seem likely that its rs485 4
wire ( they call it ebus).
The interface has only the ebus port and the usb port on it, however there are apparently two versions available.
If you could work out the ebus pins i would expect you could get most rs485 interfaces to work.

Only if the USB vendor and product ID are correct for the application/driver. It may use a virtual comm port which makes thing a lot easier.
