WxGoos-1 Climate Monitor Installation Instructions Click here to download these instructions in PDF format

Connections

The WxGoos-1 is a self-contained web server and requires 6vcd of power at 600ma. A center-positive plug is used.

There are five ports:

  1. 10/100 Ethernet RJ-45 receptacle
  2. Power input
  3. Eight RJ-11 ports for remote sensors and accessory communication
  4. Three (C,1,2,3,C) general purpose 0 - 5vdc analog sensing ports with built-in loop current. Typically used for door position sensing, but can measure and low-impedance (>5K ohm) dc signal.
  5. Two LED lamps show serial bus activity.

Setting an IP Address

The WxGoos has permanent IP address used for initial set-up and to access the unit if you forget the address that you assign it. The permanent address is shown on front of the WxGoos case:

IP 192.168.123.123
Mask 255.255.255.0
Gateway 192.168.123.1

First time setup:

  1. Connect the WxGoos to your computer using either a hub or a cross-over cable.
  2. On your computer, go to "Start > Settings > Control Panel > Network and Dial Connections"
  3. Right Click on "Local Area Connection" and select "Properties."
  4. Highlight "Internet Protocol (TCP/IP)" and select "Properties."
  5. Select the option to "Use the following IP address" and enter:
  6. IP 192.168.123.1
    Mask 255.255.255.0
    Gateway 192.168.123.1
  7. Click "OK" twice.
  8. You can now access the unit using your web browser


Typical Network Card Settings

The PC or Laptop's Network Interface Card must be configured to recognize the 192 class address.

Go to "Control Panel" or "Network Settings" and temporarily set your Network Card to the addresses shown on the drawing.

Be sure to disable the DHCP setting button. The WxGoos-1 is capable of DHCP operation but that setting can be used once the unit is installed.

Note that some computers will require a reboot to change the IP address.

Remote Temperature Sensors

Up to 16 Remote Temperature Sensors can be attached to the WxGoos-1. Each Sensor has a unique 64 bit address. The sensors are automatically discovered and added to the web page information.

The supplied wires can be extended (or shortened) using Cat 3 wire or other telephone-type wire.

Note that the sensor wiring must be straight-through: reversing polarity will cause all sensors to become temporarily disabled until the crossed-over wire is removed.

The sensors use a low speed serial network which is subject to network signalling constraints. Star configurations limit cable length; long, single sensor installations give maximum cable length.

Typical installations should yield runs of hundreds of feet. Users report that six Remote Temperature Sensors with 100' cables function, but the seventh will not discover.

Current Transformer - Direct

Current Transducers convert alternating current (ac) current into 0-5vdc signals. The output is linear.

Connect up to three directly into the small screw terminals labeled C,1,2,3,C. The "C" terminals are negative or ground and the numbered terminals are positive.

You can rename Current Transformers in the Display tab.

Current Transformers - Serial Bus Interface Units

Where more than three current measurements are needed, Serial Bus Interface Units can be used. Each Sensor has a unique 64 bit address. The sensors are automatically discovered and added to the web page information.

The supplied wires can be extended (or shortened) using Cat 3 wire or other telephone-type wire.

The pig-tail wires extending from the small interface units are 24 awg stranded wire and can be extended by at least 100' using wire nuts or by soldering extension wire and insulating with shrink wrap.

Door Switch Wiring - Three

The most common door switch configuration uses three magentic door switches.

No polarity observance is required. Use 24 awg solid wire.

Either Normally Open or Normally Closed switches can be used. NC switches are recommended as the door will be declared open if the connecting wire is broken.

Door Sensors can be renamed in the Display tab.

For emailing to occur upon each opening of the door, make sure that the upper trip limit is set to a value of 120 or above.

Note that there is a significant delay in reporting door open due to inherent Internet delays.

Extending Door Switches

If more than three door switches are needed, additional switches can be added in serial. If one opens, the chain is broken, and thus the entire group is classified as open.

There is no limit to the number of switches that can be used except for wire length, which maxes out at around 400'.

Water Sensor

Water sensors act as conductivity bridges. To function, the water sensor must be set directly on the floor.

A dry sensor reads 99 and a wet sensor reads 30 or below. As with door sensors, make sure the upper limit is set to 120 or above.

Connect using awg 24 wire with a maximum aggregate length of around 400'

Up to three sensors may be used independently. The illustration at right shows two sensors.

Water sensors can be renamed in the Display tab.

AXIS IP-Enabled Web Cam

To set up the AXIS web cam for use with the WeatherGoose, complete the directions included with the camera and then follow these steps:

  1. Make sure that the camera is set to allow anonymous access:
    • Select "Setup" on the AXIS Camera's main page.
    • Select "Users" from the list at left.
    • Check the box that says "Enable anonymous viewer login (no user name or password required)."
    • Save the changes and close the window.
  2. Enter the IP address of the camera into the "AXIS Camera Configuration" box under the "Configuration" tab of the WeatherGoose and hit "Save Changes."
  3. A live image will appear on the "Display" tab, under the internal sensor readings.


Power Egg

The Power Egg may be used as a standalone device or attached to a WeatherGoose via a "straight through" phone cable.

Standard phone cable will not work, as the wires on both ends are not in the same orientation.

The standard order for both ends of a straight through wire is (from left to right): Yellow - Green - Red - Black

The order for one end of a crossover wire is (from left to right): Black - Red - Green - Yellow
The other end uses standard order.

Note that wire type is determined by the pinouts of the connectors when the connectors are held with the pins facing upward.



Using Splitters and Hubs

Any serial device (Remote Temperature Sensors, Power Eggs, Serial Bus Interface Units, etc.) may be attached to the WeatherGoose via a telephone splitter or 5-port hub.

Connect devixes without built-in cables to the splitter or hub using straight through cables.

Devices with attached cables should be plugged directly into the hub or splitter.

Connect a 2 or 3 port splitter to the WeatherGoose using a crossover cable.

Connect a hub to the WeatherGoose via the hub's built-in cable.

An example configuration is shown at right.
