Temperature sensors 7 series WebBricks - Use star wiring now.

We've changed the one wire data interface circuit with the 7 series. You can now use star wiring where any one run does not exceed 68 metres. If your need a run above 68 metres we can make some bus accelerators available. Testing 4 x 50m + 1 x 68m OK 4 x 50m + 1 x 86m Fail(i.e. we found the limit...

Re: Cabling of the Dallas Temp Sensors,

Hi Anthony, I am glad to hear that you have got the sensors working now. Going by the description of your problem, the wrongly connected 18b20 was shorting out the external 5V rail and causing a brown out of the internal 5V rail. In turn leading to the processor not starting properly and the webserver...

Re: Cabling of the Dallas Temp Sensors,

Further to a conversation with one of my colleagues, I have been looking at the Dallas datasheet thinking that the plan view of the sensor was the top looking down, inspite of the diagram stating bottom. He explained the details that bottom was looking up the legs of the connector not the top down, hence...

Cabling of the Dallas Temp Sensors,

HI All, Playing with the Web brick and the dallas sensors and when I use a Breadblock and made up cable to connect the sensor and reboot the Webbrick the webbrick does not connect back to the network. When I disconnect one of the leads from the sensor the Webbrick is able to log back to the network....

Re: Temp sensor question

Thanks for the response, but that seems to differ from the posting Andy made here http://community.webbricksystems.com/forums/p/222/588.aspx#588 . The maximum number of sensors on a run I have is 5, but for the Dallas sensors on the T1 input, they can connect 5 sensors in a bus design (so I believe)...

Re: Temp sensor question

Hi I have seen that if I have temp sensors running in a serial run, if I connect one at the end of the line then it seems to pick up, but when I connect one in-line using one of these http://cpc.farnell.com/jsp/search/productdetail.jsp?SKU=CN04645 and punching the connectors for temp sensor and RJ45...
