6 SENSUS-PROTOCOL METER SUPPORT The Sensus Protocol, as implemented within the Sensus ICE™ and OMNI T2 registers, the Badger ADE register, and numerous compatibles, is fully supported by the EtherMeter. Important Notes: (1) Most Sensus-compatible registers do not provide the maximum resolution (digits) by default, and therefore may require factory pre-programming. See the Meter Compatibility Matrix for configuration details. (2) Wire color-coding for Sensus-compatibles varies among meter brands.
METER HOOKUP FOR SENSUS-COMPATIBLE REGISTERS: The following diagram demonstrates the hookup of a Sensus-compatible encoder register to Meter Channel 1 of the EtherMeter. Terminals 14, 15, and 16 are used in this case. Hookup to Meter Channel 2 will be identical, except terminals 17, 18, and 19 are used. PRODUCT/MAC ID LABEL EtherMeter™ AMR-Industrial Interface scadametrics.
PARALLEL ETHERMETER HOOKUP FOR SENSUS-COMPATIBLE REGISTERS: Two EtherMeters may be connected in parallel to a single meter register with the aid of the Radio-Read Filter (SCADAMETRICS P/N RRF-50). The following diagram demonstrates the hookup of a Sensus-compatible encoder register to two EtherMeters. In this example, terminals 14, 15, and 16 are used on both EtherMeters (Meter Channel 1). However, either channel may be used on each EtherMeter. Check the Meter Compatibility Matrix on scadametrics.
PARALLEL TOUCH-READ HOOKUP FOR SENSUS-COMPATIBLE REGISTERS: The EtherMeter may be connected to a meter register in parallel with a touch-read pad. However, the addition of a signal filter is required (SCADAMETRICS P/N TRF-100). The following diagram demonstrates the hookup of a Sensus-compatible encoder register to Meter Channel 1 of the EtherMeter, and in parallel with an inductive touch-read pad. Terminals 14, 15, and 16 are used in this case.
7 NEPTUNE-PROTOCOL METER SUPPORT The Neptune Protocol, as implemented within the E-Coder™ 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.

8 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 CAUTION: The EtherMeter utilizes an RJ-45 jack for the RS-232C serial port AND another RJ-45 jack for the Ethernet port. The device was intentionally designed in this manner so as to reduce the number of cable types required by the SCADA Integrator.
Note the following QVS color codes as mapped to the RS-232C (EIA-561) Jack: QVS ADAPTOR WIRE COLOR BLUE ORANGE BLACK RED GREEN YELLOW IMPLEMENTED IN THE ETHERMETER? FUNCTION RING INDICATOR NO DCD (OR CTS) YES DTR YES (TIED TO V+) SIG GND YES RxD (DATA RECEIVED BY ETHERMETER) TxD (DATA TRANSMITTED BY ETHERMETER) YES YES BROWN CTS NO (BUT SEE DCD (ORANGE) ABOVE) WHITE RTS YES RS-485 Serial Port The RS-485 serial port is implemented within three (3) Phoenix Contact screw terminals.
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. MODBUS/TCP (4 sockets) is active at all times on TCP port 502, and MODBUS/UDP is active at all times on UDP port 502. EtherNet/IP (4 sockets) is active at all times on TCP port 44818.
9 RADIO INTERFACE Support is provided for direct connection to most popular industrial radio modems. Depending upon the radio, the connection may be made via the RS-232C or RS-485 serial port, or via the Ethernet port. Serial Port parameters may be tailored for the radio via the Settings Menu. The following list, although not exhaustive, enumerates some of the most popular, compatible industrial radio modems.
10 AUXILIARY I/O CHANNELS As an added benefit, the EtherMeter is equipped with 4 auxiliary inputs and outputs. These additional I/O make the device suitable for deployment as a standalone RTU at low-complexity locations, such as master meter vaults or even simple pumping stations. Auxiliary I/O Type Digital Input (0 or 1) Notes Dry Contact Only. Closed = ON (1) Open = OFF (0) Non-Isolated, Fused. 0-5V TTL Requires an external NRTL-Listed or Recognized Solid-State Relay. eg.
4-20mA (default) or 0-5VDC. 0-5VDC is activated by removing JP1 (inside case). 4-20mA loop resistance = 240 Ohms. AIN1- is connected to DC Common (GND). Caution: AIN1+ should NEVER be connected to a voltage greater than 5VDC above the DC common. (See Recommended Wiring Diagram later in this section.) Non-Isolated, Fused. If isolation is desired, an external analog-to-analog isolation module may be used. (eg. Dataforth Sensorlex® 8B series or DSCA series modules.
CORRECT ANALOG INPUT WIRING: (NOTE THAT THE TRANSDUCER NEGATIVE IS CORRECTLY CONNECTED TO AIN1+.) INCORRECT ANALOG INPUT WIRING: (NOTE THAT THE TRANSDUCER POSITIVE IS INCORRECTLY CONNECTED TO AIN1-.) (NOTE THAT AIN1+ IS INCORRECTLY CONNECTED TO THE 24VDC SUPPLY, WHICH IS GREATER THAN THE MAXIMUM (5VDC) ABOVE THE SUPPLY COMMON.) PRODUCT/MAC ID LABEL EtherMeter™ AMR-Industrial Interface scadametrics.
In the previous illustration, wiring is shown for Analog Input Channel #1, although the principles are the same for Analog Input Channel #2. The following diagram is an example of an EtherMeter deployed as a standalone RTU. Note the use of the auxiliary I/O to provide ON/OFF signaling and analog input monitoring, in addition to monitoring one (or two) meter registers.
11 SETUP AND DIAGNOSTIC UTILITIES In order to set up the EtherMeter, the technician should actuate the #1 dip switch to the “up” position. At this point, industrial protocols are disabled on the active serial port (RS-232 or RS485, depending upon the #2 dip switch). In setup mode, the serial port operates with the following parameters: 8 data bits, 1 start bit, 1 stop bit, no parity, no flow control. The technician should press the key to refresh the screen.

Sample MODBUS/RTU Commands: The following samples are provided to familiarize the user with a few of the core EtherMeter MODBUS/RTU commands. In all samples, the device address=4. Note that the users’ responses will vary in accordance with the unique I/O state of each EtherMeter.
TOTALIZATION AND FLOW DATA FORMAT: The EtherMeter was designed in such a way as to simplify and compress the formatting of all reported data. As shown in the previous charts, no floating point or 64-bit registers are implemented in the holding (4xxxx) registers, as all data is represented internally as 32-bit long integers (signed or unsigned) and 16-bit signed integers.
EXAMPLE: Consider the following case of a meter register installed on meter channel 1. This register contains 8 variable digits plus two (2) fixed zeros on the right. (EXP1=+2.)

17 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. A Screen Image of a page served by the EtherMeter Web Server.
The following web pages are served by the EtherMeter: /index.html /s.html /b.html A dual-frame web page, containing s.html and b.html The SCADAmetrics splash screen web page The basic data web page Through the use of an off-board web server, customized, frame-based web pages may be developed for displaying data from multiple installed EtherMeters™.
18 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. Windows® TELNET (bundled with Microsoft® Windows®) and HyperTerminal Private Edition™ (By Hilgraeve) are the recommended and supported TELNET clients.
19 NETWORK SECURITY The networking capabilities of the EtherMeter are very basic; and 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.
