• DAVIS Wireless Repeater 7624, Product # 7624 & 7625 W IRELESS R EPEATER WITH SOLAR OR AC-POWER The Wireless Repeater receives data from any DavisTalk™-compatible trans- mitter and re-transmits it to any DavisTalk-compatible receiver. The repeater extends the transmission range and improves reception between the transmit- ter and the receiver. Each repeater has a transmitting and receiving range of up to 400' (120 m) depending upon the terrain. The repeater can listen for up to eight different transmitter signals and can pass those signals on to another repeater or to any number of receivers. Note: The Wireless Repeater operates on a low power

• Single Transmitter, Single Repeater Installation Page 3 Single Transmitter, Single Repeater Installation If you have just one DavisTalk transmitter and just one repeater, simply follow the instructions below to install your system. If you have a more complex setup that involves multiple repeaters or multiple transmitters within 400' (120 m) of each other, see “Advanced Installations�

• DAVIS Wireless Repeater 7624, Page 4 Wireless Repeater Note: If you’re using only one transmitter, one repeater, and one console, all three devices are set at the factory to broadcast and receive on Davis ID code #1. You won’t need to change anything, unless you’ve got a neighbor broadcasting on the same ID code. Choosing a Location The range of the radio transmission depends on several factors. Note: Given the maximum ranges below, the repeater may need to be somewhat closer to the receiver than to the transmitter. Typical maximum ranges between the transmitter

• Single Transmitter, Single Repeater Installation Page 5 Testing Proposed Locations Test your proposed transmitter, repeater and receiver locations to ensure successful data transmission as follows: 1. Make sure your transmitter and receiver are in position and are operating in test mode. To place the Wireless Repeater in test mode, flip Repeater ID DIP switch #4

• DAVIS Wireless Repeater 7624, Page 6 Wireless Repeater ✦ Solar-Power Model Plug the power cord from the battery to the jack marked POWER as shown below. Watch for the LEDs to light, (as described below). Applying Power to the Solar-Powered Repeater Both LEDs flash once when you apply power. The repeater performs a self- diagnostic test that lasts about seven seconds. When the test is completed, both LEDs flash again twice. After that second double-flash, the repeater begins listening for a signal. If it finds one, the lower LED flashes as

• DAVIS Wireless Repeater 7624, Single Transmitter, Single Repeater Installation Page 7 4. When you find a location that works, switch all three units out of test mode. If the transmitter is in test mode, restore to normal mode to conserve power. If you’re using a Vantage Pro console/receiver, use Setup mode to temporarily deactivate all transmitter IDs. Similarly, to switch the repeater out of test mode, flip the Repeater ID DIP switch #4 from the TEST position to the off position as shown below. Repeater DIP Switch Set to TEST MODE OFF Note: Leaving the repeater in test mode will cause the LEDs to flash unnecessarily and t

• DAVIS Wireless Repeater 7624, Page 8 Wireless Repeater Mounting the Repeater Once you determine that your chosen location transmits and receives the sig- nal, continue with the installation by mounting the repeater. Mounting hard- ware has been included for the most common installations (see figure on page 9 for instructions). CAUTION: Any prominent object, including an outside-mounted repeater, can attract a lightning strike. If lightning strikes your unit or strikes somewhere nearby, the unit’s internal electronics may suffer. The unit itself has been designed with considerable surge protection, but to safeguard nearby equipment and structures, we recommend following local recommen- dations on properly gr

• Mounting the Repeater Page 9 Mounting the Solar-Powered Repeater 1. Mount the shelter against a wall or post, or on a pipe. CAUTION: Remember to face the solar panel south in the Northern Hemisphere and north in the Southern Hemisphere for maximum sun exposure. ✦ Wall or Post Attach the shelter to the mounting surface in the desired location using the lag screws an

• DAVIS Wireless Repeater 7624, Page 10 Wireless Repeater Advanced Installations Daisy-Chain Installation (Multiple Repeaters) To transmit data up to one and a half miles (two and a half kilometers), or to improve reception in hilly, heavily-wooded or urban areas, you can daisy- chain up to eight repeaters together. For instructions on daisy-chaining multi- ple repeaters, see below; for instructions on adding multiple transmitters to the network as well, see page 12. Daisy-Chain Installation - Multiple Repeaters To install a chain of more than one repeater, follow the instructions for a single repeater installation. Before you apply power to test the system, set Repeat

• DAVIS Wireless Repeater 7624, Advanced Installations Page 11 So, for example, the second (B) repeater’s DIP switches will be set to OFF, OFF, ON, while the third (C) will be set to OFF, ON, OFF, as shown below. DIP Switches on Repeaters A, B, and C Setting the Transmitter ID Codes on the Repeater Once you have set the Repeater ID codes, determine whether you need to set Transmitter ID codes. If you have only one transmitter and its DIP switches are set to the default ID code (#1), then you do not need to set any transmitter ID codes on the repeater closest to the transmitter. All other repeaters must have all transmitter ID

• DAVIS Wireless Repeater 7624, Page 12 Wireless Repeater Network Installation (Multiple Transmitters) If you have two or more transmitters in your network, follow the instructions as if for a multiple repeater installation. Before you apply power to test your chosen locations, set unique ID codes for each transmitter and then set the clos- est repeater to each transmitter to listen to that transmitter. Note: Each transmitter in your network must have a different ID code so that its signal remains distinct and identifiable throughout the network. See your Wireless Weather Station or the appropriate DavisTalk™compatible product manual for instructions on how to set the

• DAVIS Wireless Repeater 7624, Advanced Installations Page 13 ✦ Combo Network — Multiple Transmitters AND Multiple Repeaters A combo network can have any combinations of the multiple transmitter network on page 12 and the daisy-chain network on page 10. In the example below, the data all flows in one direction; it enters the network at a point somewhere upstream and exits the network somewhere downstream. Combo Network- Multiple Transmitters and Multiple Repeaters Note: No matter how closely they are spaced, no two repeaters should be set up to listen to the same transmitter directly—this onl

• DAVIS Wireless Repeater 7624, Page 14 Wireless Repeater 5. Turn off the “farthest” transmitter and then add the second farthest trans- mitter (and its receiver) to your network. Check the reception of that sec- ond signal at each point. Ensure that your network is functioning properly at every stage so that if, at some point, you add a transmitter, repeater, or receiver that is malfunc- tioning or is poorly positioned, you will know immediately. 6. Add additional transmitter/receiver pairs one at a time, making sure to test only one signal (i.e., one pair) at a time. 7. Once each transmitter/receiver pair has been tested by itse

• DAVIS Wireless Repeater 7624, Troubleshooting Page 15 8. Take all transmitters, repeaters, and receivers out of test mode. Consult your installation manuals to find out how to take the units out of test mode. Leaving any of the units in test mode drains power. Troubleshooting Please check the troubleshooting list below if you experience a problem with your unit. If you still are unable to solve the problem, we encourage you to call Technical Support at (510) 732-7814 for assistance (Mon-Fri, 7:00am – 5:30pm Pacific Time). Note: Please do not return your unit for repair without prior authorization. Note: Repeater ID DIP switc
