IR2DWW7614Weather Transmitter

Product # 7614 & 7615 Wireless R epeater Installation Manual The Wireless Repeater receives data from a Wireless Weather Station sensor array and re-transmits it to the console. The repeater serves to extend the transmission range and improve reception between the sensor array’s trans- mitter and the console’s receiver. One repeater can send data to any number of Monitor II or Wizard III consoles, as long as each console contains a receiver. It can also receive and re-transmit data from up to 8 sensor arrays, as long as each array has a transmitter set to a unique ID code. The repeater’s flexibility allows you to put together your weather system in a number of different ways. The most common setup is to plant the repeater in between a transmitter and a receiver to improve reception. Another possibility is to plant a series of repeaters to carry the transmitter’s signal over a longer distance, or around obstacles. Note: The Wireless Repeater operates on a low power frequency that does not require you to obtain an FCC license. Installing the Wireless Repeater How you go about installing the repeater depends on how many repeaters and transmitters you plan to install. The first section below will discuss the most common and simplest installation—that of one transmitter, one repeater and one receiver. The following section will discuss daisy-chaining the repeaters in succession to increase the range. Single Transmitter, Single Repeater Installation If you have just one sensor array (with transmitter) and just one repeater, sim- ply follow the instructions below to install your system. Page 2Wireless Repeater Choosing a Location F AC-Powered Repeaters Install in a sheltered location, with access to an AC-power outlet. Posi- tion between the transmitter and the receiver so as to minimize the num- ber of walls and other obstacles between both the transmitter and the repeater or the repeater and the receiver. F Solar-Powered Repeaters Find an outdoor location between the transmitter and the receiver so as to minimize range and obstructions. Position the solar panel such that it will receive maximum exposure. Setting up the Repeater The repeater is pre-set by the factory to listen for a transmitter whose ID code is also set to the factory default. If you have not reset the transmitter’s ID code from the factory default, then your repeater should pick up its signal automati- cally. If you have changed the transmitter ID code to one of the 7 other optional dip switch settings, you need to set the repeater to listen for that ID code. To do so, first find your current transmitter setting in the following table: Then, set your repeater to listen for that ID code by flipping the appropriate SENSORLINK TX dip switch. For example, if your transmitter’s dip switches are set to OFF, ON, OFF, then you would flip dip switch #3 on your repeater to ON. Powering the Repeater To apply power to the repeater, do the following: F AC-Powered Repeaters Plug the AC-power adapter into the jack marked POWER, and into an AC-power outlet. F Solar-Powered Repeaters Plug the solar power cord into the the jack marked POWER.

If all is well, both LEDs should flash again, two times quickly, about 12 seconds later. After that second double-flash, the unit begins looking for a signal. If it finds one, the lower LED will flash as the data is received and then the upper one will flash as it trans- mits. Test Mode In test mode the lower green LED flashed each time the unit receives data. The upper green LED flashes when it re-transmits that data. Use this mode to ver- ify that your transmitter is working. Turn off test mode to get the longest bat- tery life. Test mode is enabled by toggling the fourth Repeater ID dip switch to the ON position and then, if necessary, removing and reapplying power. Multiple Repeaters Installation If you have more than one repeater in your network, follow the instructions as if for a single repeater installation but, before you apply power, set the repeater ID codes so that each will listen to the repeater before it in succession. The first repeater (i.e., the repeater closest to the transmitter) needs no adjustment. The second repeater, however, needs to be set to Repeater ID #2; and the third, to #3; and so on. In this way, the third repeater will only tune into signals from the second, and the second will only tune into signals from the first, and so on, thereby improving reception. To set each repeater’s ID code (except the first), use the table below to set the Repeater ID dip switches: Once you have set the ID codes, simply continue with the “Powering the Repeater” instructions on page 2. There is no need to configure the repeaters to listen to a specific transmitter ID code, unless you want a repeater to listen to an entirely new transmitter aside from the one whose signal it’s repeating.

4/30/99 Wireless Repeater Model # 7614 Theor y of Operation The Wireless Repeater consists of a single printed circuit board (PCB). Its purpose is to receive data packets from a SensorLink Transmitter, and rebroadcast them with some ad- ditional information appended to the end. The data packet is on-off keyed standard 4800 baud NRZ patterns from a UART, six bytes (about 12.5mS) from a SensorLink Transmitter, and re-sent as nine bytes (about 18mS), and packets are occur about every 2.5 seconds. The packets are received by an RFM RX2010 module, sent to a microprocessor for buffer- ing and checking, then forwarded to an RFM HX2000 transmitter module for broadcast. These RFM modules operate at 916.5MHz, and use on-circuit-board traces for antennas. See attached schematic diagram #07312.050.
