Chapter 1___________________________________________________ Theory of Operation C&I Gas Meter Interface Purpose The C&I Gas Meter Interface is a programmable end-point device, designed to replace or supplement a customer’s existing mechanical utility meter index. Using a magnetic pulse output adapter to interface to the meter output, it can be installed on a variety of meter brands. The C&I Gas Meter Interface end-point device allows for accurate, near-real-time customer utility use information, which can be read from a remote location. Functionality The C&I Gas Meter Interface end-point device performs two basic functions: • Gathering and recording customer utility use information directly at the metering point. • Sending and receiving messages to and from the utility company computer system such as: - Utility use, status, alarm data, and similar information. - Data requests, configuration, and verification messages. C&I Gas Meter Interface end-point devices communicate with the utility company computer system using a combination of Local Area Networks (LAN), AxisGateTM nodes, and a Wide Area Network (WAN). Components C&I Gas Meter Interfaces are Innovatec end-point devices, containing two primary components: a digital processor and a radio transceiver. The digital processor within the end-point device gathers and records utility use data at the metering point. Every time the meter drive rotates, pulses are recorded by the digital processor. The pulses are converted into utility use data, and this data is stored until readings are requested from the utility. Each C&I Gas Meter Interface also contains a 900MHz two-way radio frequency (RF) transceiver. This radio provides communication between the end-point device, and an AxisGateTM node. Depending upon the communication distance involved, and Innovatec relay might be used between the end-point device and the node, to extend RF communications. This RF connection between the end-point device and the node, possibly through a relay, is a Local Area Network (LAN). AxisGateTM nodes then communicate with the rest of the AxisPathTM network using a Wide Area Network (WAN). This communication allows C&I Gas Meter Interfaces to transmit use data to the utility, or to receive requests or programming instructions from the utility, or from a technician or installer using a Field Service Unit attached to a laptop computer.
See Innovatec publication 98-00004 (System Summary) for a more detailed explanation of communications on the Local Area Network (LAN) and Wide Area Network (WAN).

Chapter 3_____________________________________________ Installation and Initialization Introduction This section includes a set of detailed procedures for installation, configuration, and testing. CAUTION Read and study the following safety information before you proceed with installation. In addition, cautions and warnings appear within procedures and throughout the test, where appropriate, to remind you of any related safety information. Safety Information • Observe the following safety guidelines. Careful planning of every job is essential. Nothing should be taken for granted. Do not take chances! • Read and follow all approved policies and procedures provided by your employer associated with the procedures in this manual. • Keep the work area clean and dry. Cluttered work areas cause accidents and injuries. • Provide good lighting in the work area. You cannot work safely if you cannot see what you are doing. • Report unsafe conditions or defective equipment to your immediate supervisor. • Select the right tool for the job. Use tools properly. Keep tools in good working order. • Handle materials carefully. Lift and carry properly. • Keep unauthorized people out of the work area. Be especially cautious of children, who tend to be drawn to work activity. • Innovatec Communications LLC assumes no liability for the customer’s failure to follow these safety guidelines. Equipment Needs This section lists, and briefly describes, the various pieces of equipment required for C&I Gas Meter Interface end-point device installation, initialization, and testing processes. • Laptop computer-Runs the FSA software, which stores and retrieves work order information, and configures and tests installed C&I Gas Meter Interfaces. • Field Service Unit-900 MHz two-way radio frequency (RF) transceiver, allowing communication with an IMU for initialization.’ Before Installation
Field Service Unit Set-Up The Field Service Unit is a 900 MHz two-way radio frequency (RF) transceiver, used for configuring and testing Innovatec devices. After arriving at the customer site, activate and test the Field Service Unit as follows: CAUTION DO NOT turn the Field Service Unit ON if the antenna is not installed. Damage to the Field Service Unit will result. 1. Plug the Field Service Unit connection cord into the serial port of the laptop computer. 2. Plug a 9 VDC / 500 mA power supply into the Field Service Unit power socket. CAUTION Using anything other than a 9 VDC / 500 mA power source may damage the Field Service Unit. 3. Turn on the Field Service Unit. An indicator light will shine if the Field Service Unit power supply is functioning correctly. Installation Procedure 1. Remove index register from C&I gas meter. For American, Rockwell and Sprague meters, remove the index register and replace with the Pulsimatic pulse output register or the RioTronics index register with pulse output. For a Roots meter interface, attach the appropriately modified register head with pulse output to the meter before installing the pulse output pickup device. 2. Attach the Innovatec C&I Gas Meter Interface (p/n 1620-05001) to a surrounding fixture to the gas meter. Fixturing locations can include the meter piping, meter fixturing brackets or surrounding structures. 3. Attach the cable assembly from the Pulsimatic or RioTronics pulse output generator to the Innovatec C&I Gas Meter Interface (p/n 1620-05001). The cable assembly attaches with a ‘push and twist’ lock for the weather-resistant seal. Start the Field Service Application Note See Innovatec publication 98-00001 (Field Service Application User’s Guide) for a more detailed explanation of FSA operation. 1. Turn on the laptop computer. 2. Launch the FSA software. No error messages will display if the connection between the computer and the Field Service Unit is working. 3. Log in to the Field Service Application.
Install the Pulse Output Interface Device For American/Sprague and Rockwell meters, interface with either the Pulsimatic pulse output adapter or the RioTronics adapter. • Install the Pulsimatic unit in line with the index register and upon installation of the unit, replace the index register on top of the Pulsimatic. • Install the RioTronics-enabled index register in place of the existing index register. For Dresser Industries’ Roots meters, please follow the instructions for installation of the RioTronics Interface module. Install the Innovatec C&I Gas Meter Interface radio device to the surrounding structure which can include the meter piping, meter fixtures/supports or some adjacent structure to the meter. Connect the meter pulse output device to the C&I Gas Meter Interface by using the weather-resistant cable assembly from the pulse output device. Setup the Radio for Communication through the Gateway
