TS4-TW-221RDiversity Repeater

Tehama System Installation Guide General Description The Tehama AMR system consists of three device types to remotely monitor various environmental and utility readings and provide the data to a central database or PC for formal presentation and reporting. Metering Data Transceiver (MDT) devices will be placed in all locations requiring local monitoring of data. The MDT devices will transmit time stamped data to the DCAP device, which receives the data and stores it in a Database. The database information is available over Ethernet on the local LAN or the Internet. For MDTs that are out of range from the DCAP, Repeater devices are added in appropriate locations to relay the data between MDTs and the DCAP The system operates in the 915Mhz ISM bands using off-the-shelf FSK RFIC radios. The system operates as a Frequency Hopper over 60 narrow band frequency channels, incorporating a bidirectional communication link with Acknowledge (ACK) messages to ensure all data reaches the DCAP. The MDTs are battery operated, bursting data packets at pre-programmed times then shutting down to conserve battery life, estimated to exceed 5 years. The DCAP and Repeater units are line powered. With an typical MDT transmission rate of four per hour for time of use applications, a single DCAP can accommodate up to 1000 MDTs. There is no limit to the number of repeaters, though an average installation may require one Repeater for every 20-30 MDT/MDTs. Figure 1: Typical System Tehama Installation Guide! of ! 16 A system consists of two or three types of hardware, and a software program: • One DCAP Unit or Access Point • A variable number of MDT units, each with 2 AA batteries • A variable number of Repeater units (optional, depending on size of installation) with external DC power supply. • Tehama Configuration Utility (CIT) running on a PC Warning Tehama Configuration & Installation Tool (CIT) You should have received a copy of the Tehama Configuration and Installation Tool (CIT) software. If not, please contact [email protected] and request the link. The CIT runs on a Windows based PC. More detailed information can be found in the Tehama CIT User Manual or the Tehama QuickStart Guide. The tool can be run on the PC either prior to or during a site installation, or when new MDTs are added to a system. The tool is used to add configuration data to the database. Examples of configuration data include the name, type, and location of equipment an MDT is connected to, and alarm trigger settings for the different MDTs. Data Collecting Access Point (DCAP) Setup This step configures the Internet settings for the DCAP and lets you set unique passwords for remote access. • Power up the DCAP with the supplied power adaptor. • Screw in the AP antenna that came with the unit. • Attach the supplied USB cable to your computer and to the AP. If this is the first time attaching tan AP, Windows may respond with a “found new hardware” message. Follow the steps to let Windows download the driver software. • Attach the AP to your local LAN with the supplied Ethernet cable. • Launch the CIT tool on the PC • Go to the Config menu and select DCAP. The Serial Port field should be automatically populated with the correct COM port • Click on the Get button to see the current settings • DCHP (Dynamic IP Address) is the default. If you want a static IP, select static and fill out the extra fields. Tehama Installation Guide! of ! 26 NOTE: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT • Set the MySQL database passwords for both users and click “Set”. Clicking on the “Default Vals” button will fill the fields with the factory default passwords. This is provided as a convenience if password security is not an issue (for example in an evaluation system). • Click on the “Create a Site Entry” button to auto-fill a Site entry with the information from this panel. • Unplug the USB cable. It is not needed again unless you need to change the IP address or the database passwords at a future time. MDT Configuration All MDT come from the factory with a default factory-set configuration. The following parameters can be custom configured at the factory only; they cannot be changed by the user. There are no parameters which can be configured on the DCAP or Receiver. • Monitor Type, defined as the type of meter the MDT is attached to for readings. Our basic pulse MDT all work with 99% of the meters, but special units can be ordered for Hersey pulse meters, Encoder meters, etc. Additional data can be factory configured, such as temperature measurements. • Transmit Interval, defined as the time between scheduled transmissions of temperature data. Regular pulse meters transmit once every hour (60 minutes). Our Time of Use units are configured to transmit four times an hours (15 minutes). • Measure Interval, defined as the time between scheduled temperature measurements. This is used in conjunction with Temperature Change (see below) and must be smaller than the Transmit Interval time. A value of 0 for this parameter will disable measurements in between the Transmit Interval. The units for this parameter are in seconds, with default set to 0. • Temperature Change, defined as a percentage change in the Thermistor resistance value (i.e. temperature) detected by the MDT. A Delta Temp alarm will be generated within the PC Software if a MDT reading taken at a Measure Interval is more than Temperature Change percent from the prior Transmit Interval value. The units for this parameter are Percent (%), with the default value set to 0. Tehama Installation Guide! of ! 36 THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES.
