1. Overview of the TempTale RF2 System The TempTale® RF2 system consists of infrastructure components and dataloggers. The infrastructure components, TempTale RF2 Gateways (Gateways) and TempTale RF2 Repeaters (Repeaters), are installed permanently while the TempTale RF2 Dataloggers(Dataloggers) travel with the cargo and report their data when they arrive at a location that has an installed TempTale RF2 infrastructure.
The layout of the system can be viewed as a tree with the Gateway as the root and Repeaters as nodes. When planning for the layout of the TempTale RF2 infrastructure, keep in mind that Repeaters can communicate with other Repeaters, as shown below. Since the Gateway is also capable of the same functions as Repeaters, a Gateway could also communicate directly with Dataloggers to download data.
The following is a diagram illustrating the network layout for a 150 meter x 150 meter warehouse: 1.1. Important Installation Notes Regarding RF2 installation, the following important rules must be taken into consideration when determining where to mount the Gateway and Repeater infrastructure components: 1. The Gateway and Repeater MUST be mounted inside a building, where they would not be exposed to rain or dripping water.
1.2. Mounting the Gateway and Repeater The Gateway enclosure has a set of mounting tabs integrated into the enclosure, and the Repeater is supplied with a plastic mounting plate. When securing either, the correct fasteners for the wall type must be used. For hollow wall construction studded with metal or wood framing and sheathed with Drywall, Plaster or Plywood, an appropriate hollow wall such as a 3/16” toggle bolt or #10 re-usable anchor. Typical drill size is ½” for the 3/16” toggle bolt.
Various types of concrete inserts are available that are adequate for use in concrete, such as conical lead or flanged Polypropylene that will be adequate for installation. They must be individually rate to support 10 lb. (4.6 kg) minimum. Use sizes that support a #10 screw, minimum. Typical drill size is 5/16” for the #10 conical lead anchor for concrete. Follow the manufacturer’s instructions. Follow the manufacturer’s recommendation for drill depth for insert being used.
2. TempTale RF2 Gateway As mentioned previously, the TempTale RF2 Gateway is the core of the infrastructure for the network and only one Gateway can be installed per facility. The Gateway is a ruggedized, self-contained embedded computer with four antennas; two of the antennas are for 868 MHz or 915 MHz operation while the other two antennas are for 2.4 GHz operation. The 2.
2.2. Gateway Assembly When you receive the Gateway, carefully remove it from the shipping container and inspect for damage, especially if the shipping packaging appears to be damaged. If you determine there has been shipping damage, contact the carrier immediately. Determine if 915 MHz or 868 MHz antennas are required, and attach them as indicated in the diagram below. The 915 MHz antennas have two yellow stripes and the 868 MHz antennas have two gray stripes.
Next, connect the power supply provided at either of the two barrel power connectors provided. You may need to first loosen the two thumbscrews that hold the securing plate into place. After you slide the plate back, insert the power connector, slide the plate in place and tighten the thumbscrews. NOTE: YOU SHOULD ONLY USE THE 12 VDC POWER SUPPLY PROVIDED! USING ANY OTHER POWER SUPPLY MAY DAMAGE THE GATEWAY. THE SECURING PLATE IS NOT DESIGNED TO PHYSICALLY SUPPORT THE POWER SUPPLY.
2.3. RF2 Gateway Specifications Input Power +12Vdc from a SELV limited power source Weight 6 lbs.(2.75 kg) RF Band: Gateway to Datalogger North American ISM Band from 902 – 928 MHz European SRD Band from 863 to 870 MHz Frequencies - 915 MHz band 921.5 MHz 923.0 MHz 923.5 MHz 924.0 MHz 924.5 MHz Frequencies - 868 MHz band 866.1 MHz 866.5 MHz 866.7 MHz 867.1 MHz 867.
3. TempTale RF2 Repeater The TempTale RF2 Repeater serves as a connection between the Datalogger and the Gateway. The Repeater will receive the temperature records from the TempTale RF2 Datalogger and then pass the data to the Gateway which then delivers the data to the end-user software application or host computer. An installation may require no Repeaters or many, depending on the coverage area needed. The Repeater components are pictured in the next section. 3.1.
3.2. Repeater Assembly When you receive the Repeater, carefully remove it from the shipping container and inspect for damage, especially if the shipping packaging appears to be damaged. If you determine there has been shipping damage, contact the carrier immediately. Determine if 915 MHz or 868 MHz antennas are required, and attach them as indicated in the diagram below. The 915 MHz antennas have two yellow stripes and the 868 MHz antennas have two gray stripes.
4. Repeater Specifications Input Power +12Vdc from a SELV limited power source Weight 2 lbs.(1 kg) RF Band: Repeater to Datalogger North American ISM Band from 902 – 928 MHz European SRD Band from 863 to 870 MHz Frequencies - 915 MHz band 921.5 MHz 923.0 MHz 923.5 MHz 924.0 MHz 924.5 MHz Frequencies - 868 MHz band 866.1 MHz 866.5 MHz 866.7 MHz 867.1 MHz 867.
5. TempTale RF2 Datalogger The TempTale RF2 Datalogger will travel with the cargo and continuously store temperature information and a corresponding time stamp. The Datalogger will start operation when the “Start” button is pressed. The Datalogger also has two LEDs visible on the front panel; the greed LED blinks to indicate that the Datalogger is operating, taking data points, while the red LED blinks to indicate an error or alarm condition.
5.3. Logging Data The Datalogger has the capacity to store 1920 temperature records. When the 1920 record locations are full, the Datalogger will stop taking new temperature records so no existing temperature records will be overwritten. The time interval used to store data points is configurable based on the desired length of operation and is programmed into the Datalogger when shipped. When the Datalogger is running and no alarms have been triggered, the green LED will flash once every four seconds.
5.5. Datalogger Specifications RF Band: Gateway to Datalogger North American ISM Band from 902 – 928 MHz European SRD Band from 863 to 870 MHz Frequencies - 915 MHz band 921.5 MHz 923.0 MHz 923.5 MHz 924.0 MHz 924.5 MHz Frequencies - 868 MHz band 866.1 MHz 866.5 MHz 866.7 MHz 867.1 MHz 867.
6. TempTale RF2 Gateway Software 6.1. Software Overview The program to perform the functionality of the RF2 Gateway is installed on the embedded computer at the factory. This program handles 4 main functions: • • • • Manage the network and Dataloggers Download and transmit data to the server Manage alarms and event triggering Log network activity 6.2. Windows Services \ Applications The functionality required for the Gateway has been divided into a number of different programs and groups of programs,
DataTransporter This is a utility provided by Sensitech to transfer downloaded Datalogger data to Sensitech’s server. Configuration Utilities This is the collection of software tools that communicate with the Sensitech Network Manger to allow an operate to manually issue commands to the Gateway and Repeater network. These tools are usually used exclusively for diagnostic and testing purpose. Sensitech Rule Viewer This is a tool that visually illustrates the rule system.
