    If there is a Sensus-, Neptune-, or K-Frame-protocol encoder meter register that is not listed within the document as compatible based upon testing, and you would like to see it listed as such, then please contact SCADAmetrics. Note that in such cases, we may request a register for testing and verification.

  • Page 17: Sensus Protocol Meter Support

    SENSUS PROTOCOL METER SUPPORT The Sensus Protocol, as implemented within the Sensus OMNI, iPERL, & ICE™ registers, the Badger HRE & ADE registers, and numerous compatibles, is fully supported by the EtherMeter. Important Notes: (1) Sensus-compatible registers do not always provide the maximum resolution (digits) by default, and therefore the register or meter may require factory pre-programming.

  • Page 20: Neptune Protocol Meter Support

    NEPTUNE PROTOCOL METER SUPPORT The Neptune Protocol, as implemented within the E-Coder™, ProCoder™, Mach10, and ProRead line of registers, is fully supported by the EtherMeter. Important Notes: (1) See the Meter Compatibility Matrix for meter register configuration details. (2) Wire color-coding for Neptune-compatibles differs from that used in Sensus-compatibles and K-Frame-compatibles.

  • Page 26: Pulse Meter Support

    PULSE METER SUPPORT The EtherMeter provides meter-reading support for pulse-based meters. As a consequence, pulse meter signal(s) may be connected to either (or both) of the EtherMeter’s meter input channels. Pulse processing technology allows the EtherMeter to collect meter totalization and flow rate data from non-encoder-based meters.

  • Page 28 Debounce Filter: In order to mitigate the adverse effects of contact bounce, user-adjustable de-bounce logic has been implemented within the EtherMeter firmware. The user may adjust the DBn parameter to increase or decrease the pulse sensitivity. DBn refers to the minimum required quiet time enforced after the leading edge of a valid pulse has been detected.

  • Page 29: Plc/Rtu/Computer Interface

    PLC/RTU/COMPUTER INTERFACE There are currently three (3) physical types of signal connections that can be made between a PLC/RTU/Computer and the EtherMeter. • RS-232C Serial • RS-485 Serial • Ethernet RS-232C Serial Port The RS-232C serial port is implemented within a DB9-Male DTE modular jack. The pinout is as described in Section 4.
  • Page 30 Ethernet Port The Ethernet port is a 10BaseT modular jack, and operates at a maximum data rate of 10 Mbps. Both dynamic (DHCP) and static IP addressing are supported. The Ethernet port supports the ARP ping function, serves a web page on TCP port 80, and provides a Telnet Server for remote configuration and troubleshooting.

    HTTP WEB SERVER The EtherMeter offers an integral web server, which is active on TCP logical port 80. The device also features a “Ping Server”, which is useful for locating and troubleshooting the EtherMeter on a network. Note that both static IP and dynamic IP (DHCP) addressing is supported. (Static or Dynamic IP Address selection is made in the Setup Menu.) The unique MAC ID of each EtherMeter is printed on the front cover of the unit.
  • Page 71 The following web page is served by the EtherMeter: /index.html A single-frame web page containing a snapshot of the data. Through the use of an off-board web server, customized, frame-based web pages may be developed for displaying data from multiple installed EtherMeters™. The following web page is a simple example: Figure 19B.

  • Page 72: Telnet Server

    TELNET SERVER The EtherMeter provides a basic integrated TELNET server. With the use of TELNET client software, the user may log in to the EtherMeter from a remote node on the network to perform setup and maintenance tasks. However, only one (1) remote user may TELNET to the EtherMeter at any given time.

  • Page 73: Network Security

    NETWORK SECURITY The networking capabilities of the EtherMeter are very basic. Therefore, the device is not designed to be staged at network locations where it would be exposed to Internet threats. When an EtherMeter is installed within an industrial network that features a Gateway to the Internet, a firewall should be properly installed and configured to shield the EtherMeter, as well as all other industrial controls, from the vagaries of unfiltered Internet traffic.
