IR2DWW7617ConsoleLink, Model 7617

Product # 7617 C ONSOLE L INK I NSTALLATION M ANUAL The ConsoleLink Transmitter (Tx) connects to a host Weather Monitor II, Weather Wizard II & III, or Perception II. The ConsoleLink Tx transmits weather data from your host station to other DavisTalk™ compatible consoles and receiving units. This allows you to send weather data to one or more loca- tions without using any wires. Providing you have the necessary sensors, the ConsoleLink Tx will send the following weather data: The ConsoleLink Tx is user-configurable to communicate on one of 8 different ID codes. This allows multiple systems to coexist in the same geographical area. The unit includes a pass-thru connector so that a WeatherLink data logger can still be used with the host station. Note: The ConsoleLink Tx operates on a low power frequency that does not require you to obtain an FCC license.

(Refer to drawing 1A) Attaching the ConsoleLink Tx to the Host Station The transmitter has a short cable with modular connector on its free end. Insert this plug into your weather station in the jack marked "WeatherLink". The unit sits in the console base as shown. Range The range of radio transmission depends on several factors. Try to position the DavisTalk compatible receiver(s) as close to the ConsoleLink Tx as possible. Typical maximum ranges: F Line of sight: 800 feet (240 m) F Through walls and ceilings: 100 to 400 feet (30 to 120 m) F Through trees and foliage: 100 to 400 feet (30 to 120 m) Setting the ID Code The ConsoleLink Tx may be set to use any of eight selectable ID codes (the default is ID Code #1). The transmitter and receiver will only communicate with each other if they are both set to the same ID code. Use the default setting unless you have another Davis wireless system operating nearby which you want to work separately from the new system. The dip switch settings for the eight possible codes are shown below. To change to another ID, toggle dip switches 1, 2, and/or 3 on the transmitter to the desired code. Remember that the transmitter and receiver must use the same ID code in order to communicate so if you change the ID code on the transmitter, you must change the ID Code on the receiver to match. Note: Dip switch #4 is used for testing and warnings, not for ID codes (see “Test Mode” on page 3).

If the ConsoleLink Tx is working properly, it will make a single or double beep about 30 seconds after the weather station is energized. The single beep indi- cates that the unit is working properly and that no WeatheLink data logger is connected to the unit. Two beeps indicate that the unit is working properly and that a WeatheLink data logger is connected to the unit. Test Mode To verify that the ConsoleLink Tx transmitting data, a test mode is provided. In this mode the beeper beeps each time the unit transmits data (2.5 second interval). Using a WeatherLink Data Logger Install the ConsoleLink Tx as instructed above. Plug the short (3", 75mm) mod- ular connector from the WeatherLink into the ConsoleLink Tx as shown in drawing 4. Alternately, use the optional 8 ft. extension cable and coupler to make the connection. T ROUBLESHOOTING While the ConsoleLink Transmitter is designed to provide years of trouble-free operation, occasional problems may arise. If you experience a problem, please check the troubleshooters listed below before calling the factory. If you still are unable to solve the problem, call the factory at (510) 732-7814 for assistance. Please do not return your unit for repair without prior authorization. F Console is receiving erratic data Enable the Test Mode on the transmitter. If two beeps or more are heard in a 2.5-second interval, then another Davis wireless system may be operating nearby on the same ID, or a cordless phone may be operating within 10 feet of the receiver. Either try changing to a different ID code on both the receiver and the transmitter, or try moving the phone. Reapply power to the console to activate the new ID code. F Console is not receiving any data The transmitter and the receiver may be too far apart, or something in their path may be interfering, such as foliage, furnishings or cordless phones. Enable Test Mode on the transmitter to see if it is receiving data. Try mov- ing the receiver closer to the transmitter or vice versa; or eliminating possi- ble path interferences.

The EUT is receiving its power from the Weather Console, which is powered from the AC Adaptor, which is powered from a 115V/60Hz source. The on time of the transmitter in a 100ms period was measured. This on time divided by the 100ms period is the duty cycle. A 20Log(duty cycle) calculation is then performed and this factor (not to exceed 20dB) is then taken into consideration.
