Can you use regular data routers to transmit C-Bus signals

[thelauman]

Hi there,

I had a thought the other day and was wondering if is possible, here goes:

Since C-bus signalling is pretty much using the InternetProtocol to transmit its signals would it be possible to use a normal computer data router/switch and plug in the pink Cat-5 cable since after all it is transmitting data. What Im getting at is if so, then would it be possible to use the wireless flavour of router/switches and virturally transmit C-bus signals via Wi-Fi across the appropriate equipment (PC networking gear)?

For example, would it be possible to plug a regular PC interface into my laptop and one end of the pink Cat-5 fly lead into the PC interface while the other end into a wireless module (or a USB to ethernet adapter using a serial to usb adapter). At the other end of the wireless bridge the wireless router also has one end of a fly lead and the other end into say a dimmer (or onto the network). This would allow me to move throughout an installation and quick toggle the channels to make sure they turn on the right loads in the same room, rather than having someone in there yelling back as i sequentually go through each and ever channel.

Long winded i know but hope you get the idea....
Any ideas are welcome

Mate C-BUS, or at least at the 'pink cable' end isn't using any internet protocol, it is using a proprietary C-Bus protocol which is nothing at all like TCP/IP. Nor is the cable ethernet, RS-232, USB or any protocol except C-Bus. It isn't possible at all to run C-Bus through any router or network device the way you have described.

If you had a C-bus network interface (5500CN), then it would be possible to kind of do what you want to do but connecting the IP side of it to a wireless device (router), and have you PC running some of the IP enabled software. The 5500CN is what is doing the 'translating' between the app running on the network and C-Bus.

Cool.

Thanks heaps for your help buddy...

I also suppose the voltage difference of C-Bus (36vdc) and the data network (5-12 vdc) might come into as well.

Although i do like my "chips" well cooked, bit of vinegar too..

Well yes and no. They are certainly different voltages, but the whole point is they are complete and different protocols that are not compatable with one another, its that simple.

The only thing they share is the cable, but even with this the pinouts are not even close to be alike.

You need to look at the basics.

Do a bit of reading on OSI. You need to consider the Physical Layer, Network Layer and Transport Layer etc. Study the fundamentals they never change.

TCP/IP on ethernet is a complete different kettle of fish to C-Bus comms, however C-Bus does conform to the OSI model for communications as does IP.
