Page 4 Wireless Temperature Station S ETTING THE T RANSMITTER ID Each wireless transmitting station must be set to one of eight transmitter IDs. Dip-switches #1, 2 and 3 on the SIM allow you to control the ID — the “chan-nel” the station will transmit on. (Dip-switch #4 is used for transmission test-ing, not for transmitter ID.) The transmitter and receiver communicate with each other only when both are set to the same ID. The factory default transmitter ID is ‘1’. Looking at the table below, you can see that means the dip-switches are in the OFF position when each transmitting station leaves the factory, whether it is an ISS, a wireless temperature station, or another kind of station. The ISS is included with every Wireless Vantage Pro, so the console/receiver is set to find the ISS on ‘1’. Set your temperature station to its own ID number. Use a ballpoint pen or paper clip to toggle dip-switches #1, 2, and 3. The set-tings for transmitter IDs 1 – 8 are shown in the table below: Use this table to ensure that each wireless transmitting station in your system is broadcasting on its own transmitter ID.

Setting the Transmitter ID Page 5 Setting Console/Receiver(s) to Same ID 1. Put your console into Setup Mode — press and hold the DONE key and press the DOWN arrow key. The console will show you Screen 1: Transmitters. You should see the words: “RECEIVING FROM...” and “STATION NO.” followed by the transmitter IDs that your console detects. One of these should be the ID number you just set on the temperature station transmitter. If you don’t see it, make sure the console is within 10' of the transmitter, and verify that you set the dip-switches correctly. If you still don’t see it, go to “Put the transmitter in TEST mode” below. 2. Press the DONE key to move on to Screen 2: Selecting Transmitters. Setup Mode – Screen 2 is where you will set the console to recognize signals on that ID as coming from a temperature station. 3. Press the LEFT or RIGHT arrow key, or the STATION key, to scroll through transmitter IDs. When you see the ID you chose for the temperature station, use the UP or DOWN arrow keys to activate reception of that ID code. Make sure the screen shows “ON”. 4. Press the GRAPH key to change the type of station assigned to that transmitter ID. Press the GRAPH key until the word “TEMP” appears. 5. To exit Setup Mode, press and hold the DONE key. (See the Vantage Pro User’s Manual & Setup Guide : “Setup Mode – Screen 2: Selecting Transmitters.”) Viewing Current Temperature Press the TEMP key until you see an ‘outside’ temperature displayed on the console screen, with the correct Station No. displayed above or below it. This confirms communication between your temperature station and the console — go on to “Choosing a Location for the Wireless Temperature Station” on page 6. If You Do Not See Current Values from the Correct Station No. First, verify that the console/receiver is powered and is not in Setup Mode (exit Setup Mode by pressing DONE key and holding it for a moment). Then, on the temperature station, check that the battery is properly installed. Walk around the room with the console, standing for a few moments in various locations to see if you are picking up signals. Wireless Temp Page 5 Thursday, November 30, 2000 9:55 AM
Page 6 Wireless Temperature Station If you don’t see readings no matter where you stand with the console, Put the transmitter in TEST mode Dip-switch #4 on the SIM (see illustration on page 4) is the TEST dip-switch. Switch it to the ON position using a ball-point pen or paper clip. This puts the transmitter in Test Mode. An LED indicator light will flash each time it trans-mits: ✦ The LED will immediately flash once to show that the light itself functions. ✦ Then it will flash each time the transmitter broadcasts a signal, which should be every 10 seconds. If the LED flashes only once and then remains dark, there is a problem with the transmitter. See “Contacting Davis Instruments” on page 10.If the LED flashes repeatedly but your console isn’t picking up a signal any-where in the room, it could be related to one of the following causes: 1. The dip-switches were not correctly set on the transmitter. Review the procedure on page 4. 2. The ID was not correctly set on the console/receiver. Review the procedure on page 5. 3. Reception is being disrupted by RF (radio frequency) interference.4. There is a problem with the console/receiver. See “Contacting Davis Instruments” on page 10. Note: Remember to turn the Test dip-switch OFF when you’re finished testing wireless transmis- sion. If it is left ON, the blinking LED will reduce battery life significantly. C HOOSING A L OCATION FOR THE W IRELESS T EMPERATURE S TATION Taking care to choose a good location improves the accuracy, reliability, and durability of the sensor. The ideal location would be under the eaves on the NORTH SIDE of a building in the Northern Hemisphere (on the south side in the Southern Hemisphere). Avoid areas which heat up in direct sunlight, such as asphalt driveways. Wireless Temp Page 6 Thursday, November 30, 2000 9:55 AM
Choosing a Location for the Wireless Temperature Station Page 7 Consider the following factors as you choose a location for your temperature station: ✦ Place the sensor in a position where it will not be in direct sunlight and where it will have limited exposure to reflected sunlight. If possible, place the sensor at least 5' (1.5 m) from any surface which is exposed to direct sunlight. ✦ Limit the sensor’s exposure to night sky. If you are unsure about a location’s exposure to the night sky, check for dew at that location on a morning with light dew. If the area is dry, the location should work well. ✦ Place the sensor at least 10' (3 m) away from lights or lamps. ✦ Keep the sensor and its cable away from AC power lines. Do not run the sensor cable parallel to house wiring. Mount the sensor at least 30' (9 m) from high-voltage power lines and transformers. ✦ Try not to run sensor cable across large metal objects such as aluminum siding. ✦ For air temperature, use a cable tie, cable clip, or electrical tape to attach the cable to a building, post, pipe or other surface (keep the sensor itself away from the building’s surface.) ✦ For soil temperature, bury the sensor at the depth you choose. Where the cable runs along the ground, use metal or plastic conduits to protect the cable from rodents. ✦For water temperature, position the sensor as deep as you like. If the cable runs along the ground, use metal or plastic conduits to protect the cable from rodents.The Radiation Shield #7714 provides additional protection for the sensor.Range of Wireless TransmissionThe range of wireless transmission depends on many factors. For the best reception, position the transmitter shelter and your console/receiver as close together as possible.Range is up to 800' (250 m) in the line of sight, under optimal conditions. Typi-cal range under most conditions is 150' to 500' (45 to 150 m), but this may be reduced by walls, ceilings, trees, or foliage. Radio-frequency interference (RF) can also reduce transmission distance. Cordless phones and “ham” radios are common examples of RF interference.A metal roof or other large metal structure can interfere with the signal (alumi-num siding, a furnace with metal ducts, and your refrigerator are examples). Sometimes transmission between wireless units is obscured by something you cannot identify, or by some obstacle that you can’t work around. If necessary, consider using Wireless Repeater #7624 or #7625 to strengthen the signal or increase the distance between the transmitter and the console/receiver.

Page 8 Wireless Temperature StationTESTING TRANSMISSION FROM PROPOSED LOCATIONIt is very important to test reception from the proposed location before perma-nently mounting the temperature station. Place the shelter at the intended mounting site, or have someone hold it there, so you can walk around with the console/receiver for a few minutes. Rotating the antenna may help to improve reception. Test wireless reception anywhere you might want to use or mount your con-sole/receiver now or in the future. Take your time. If you aren’t picking up strong signals where you intend to place your console, better to move the shel-ter now than after it has been mounted. Experiment. If you have irregular terrain in the area, it may interfere with the signal. For example, if the transmitter is mounted downhill from the console/receiver, the ground may block a wide angle of the transmitted signal. MOUNTING THE WIRELESS TEMPERATURE STATIONMounting on a Pole1. While holding the shelter against the pole, place a U-bolt around the pole and through the two holes on at the top of the shelter. 2. Place a flat washer, a lock washer and a hex nut on each of the bolt ends.

Page 10 Wireless Temperature StationA NOTE ON SECURING CABLESTo prevent fraying or cutting of cables, secure them so they will not whip about in the wind. Secure a cable to a metal pole by wrapping electrical tape around them both. Make sure cables are secure by placing clips or ties approximately every 3 – 5' (1 – 1.6 m).Note:Do not use metal staples or a staple gun to secure cables. Metal staples—especially when installed with a staple gun—have a tendency to cut the cables.CONTACTING DAVIS INSTRUMENTS(510) 732-7814 for Technical Support, Monday – Friday, 7:00 a.m. – 5:30 p.m. Pacific Time.
