Wow you still dont understand that 9600bps is all that is needed for a lighting bus speed, You need to get out there and try some systems. You do understand that electricity runs at the same speed on the same diameter cable no matter what its bit rate. The faster the bus speed the closer the...

Can you point me to this pc, I need a serial line or 5 and 40 12v-24v inputs 20 24v outputs and 16 240v outputs, a dozen analogue inputs would be nice too. All I/Os must be 5Meg isolated. I need it to drive all this if there is a power outage for 48hrs, dont want someone cutting the power and...

wow my spec put the the m1 gold at $500NZD each 16 channel input at $100 and each 16 channel output for $300 Now thats the same price if I was to use din rail relays for each input/output. I'm not going with the M1/cbus interface now. I'm just going to use CQC to talk to the CBUS and M1 Can...

I talked to a sparky at the wholesalers the other week who has done a cbus install in a building with 190 units and there is no delay at all. Why do you keep saying 9600bps is slow???? do you know how much data is sent on startup? If its anything like the systems i am used too, each switch has...

If your going to design your own security system using a serial I/O card connected to relays or a PLC? Why not design your own lighting control, You can use 10v analog outputs to do your dimming, I thought about using a PLC as lighting control but changed my mind when i thought about what...

so everything including alarm equipment is controlled by a PC? What happens if a HDD or something fails late at night? no lights no video distribution no alarm.

in this case the cars (0's and 1's) all travel at the same speed. the speed of electricity (v=1/QeR^2pie) You will only get gridlock if there are more cars then can fit into the lanes. Your talking turning a light on/off, something that in the real world is only 1 bit wide its not HD video...

Think of a motion sensor as a switch and it switches when it detects motion. Most need 4 wires, 2 for powering it 12v/24v, 2 wires for the contact (switch) So you need some way of telling your lights what to do when it switches on/off In my case the sensor switches and turns a zone input...

It works like this. You press a button that has an address This command (button press) is sent to a logic engine ie PACA or Touch screen. How many bits is needed for this? a light switch is 1 bit (on or off) + data for its address (i dont know 8 bits maybe?) The logic engine sees the command...

Dont know how you did your maths but i have a small test setup and i can switch all loads on/off with no noticeable delay 4x 4way switches 2x 4way dimmer 1x 12way relay 1x 5500cn Your maths is way out. please remember you are scanning units not loads I dont no the math and dont care for it but...

just read your edited 1st post. Why would you build your own lighting/pc/txt/security interfaces? note also that cbus can tie the lot in for you without a pc, but it will cost you. wiser(pc) $1100NZD (get this and you dont need a computer) NIRT (IR control for equipment) $550NZD 5500CN...

Yes Clipsal have a C-Bus Open Protocols website have no idea about how it works, I dont do software. Have a read at the CIS (clipsal cbus) technical website there is docs for all their products. You cannot buy american products they do not work at 230V you can use UK stuff but good luck...

being a registered electrician i have a fair idea of what is available in NZ. Yes some of the other brands are available in NZ but the selection for a 230v product is very slim or very pricey. Plaese let me know is you find a good source for 230v z-wave or UPB products

I'm in the same boat as you,building my first house and living in New Zealand. I am going with C-BUS lighting, NESS(ELK) M1 alarm for security and automation and CQC for software to tie it all together. Down in this part of the world half the products are not available, but products like CBUS...
