1 Introduction
The Sensus Automation Remote Telemetry Module™ (RTM II) is a cost-effective communication solution
for remote monitoring and control of Intelligent Electronic Devices (IEDs) that control electric distribution
system assets such as reclosers, switches, capacitor banks, breakers, voltage regulators, and meters.
RTM II devices can be remotely configured, monitored, and controlled through the secure Sensus
AutomationControl™ Web application using any standard PC. The RTM II includes serial connections, a
USB configuration port, and easy profile management through the AutomationControl software. The
RTM II communicates using the Sensus FlexNet® private networks.
The multi-address RTM II communicates with any IED that supports DNP3 or Modbus protocols. Models
with FlexNet radios communicate using packet data over the Sensus FlexNet private networks. The
devices can be installed on any FlexNet system using the latest Automation Network Interface software.
FlexNet models incorporate all of the standard FlexNet system security features.
The devices are ideally suited for Smart Grid distribution automation applications such as reclosers,
capacitor banks, distribution switches, faulted circuit indicators, voltage regulators, distributed
generation, load control, and small substations.

DUG-10009-01 RTM II FlexNet User Guide
1.1 RTM II Overview
The RTM II uses the radio network to enable communications between IEDs with supported protocols
and Sensus AutomationControl™. When it receives data from the RTM II, AutomationControl displays
the data immediately. Alternatively, the customer can use Sensus Automation’s DNP SCADA-Xchange™
software, which uses a secure TCP/IP connection to transfer the DNP3 data directly to the utility's
SCADA system.
Most newer generation Remote Terminal Units (RTUs) and IEDs use the standard DNP3 communication
protocol to communicate with utility SCADA systems. The RTM II also provides a Modbus interface to the
many IEDs and RTUs that support this protocol.
The RTM II connects to an IED such as a recloser, voltage regulator, or capacitor bank controller through
an RS-232 serial port or an optional RS-485 serial port. The RTM II can either be installed as a
communications board within the IED enclosure or externally in its own weatherproof enclosure.

1.2 How it Works
The RTM II is programmed with a profile detailing the relevant points on the IED as well as how the user
wants the data to be reported. The RTM II accepts DNP unsolicited report-by-exception as well as
constantly polling the IED to get the latest data. When it discovers a reportable event, for example a
binary input that has changed state, it initiates a report over the radio network to AutomationControl.
Here, the data is validated and processed for distribution to the end user. In addition, control and
configuration information can be sent from the end user back to the RTM II.

3 Installing the RTM II
The RTM II can be purchased either as a communications module that is installed within the IED
enclosure or pre-installed in its own weatherproof enclosure. Follow the instructions in the RTM II
FlexNet Integration Guide to install the RTM II in your specific IED.
If your application does not come with an integration guide, see Basic Integration Guidelines on page 21
for basic integration instructions.
3.1 Before You Begin
The Automation Device Configurator software comes with your integration kit. Install the software on your
PC.
You will need to connect the device to the PC that has the Automation Device Configurator software
installed. You can use a standard USB 2.0 cable with connector type A to connector type B like Belkin

statuses every three minutes. You can change how often this information is updated by checking
Continual Refresh, which updates data every 3 seconds, or by manually refreshing as needed.
◦Green = Good. Communication to AutomationControl and/or the IEDs are working and the
device configuration has been recognized and processed at the headend system.
◦Red = Bad. Something needs attention. If the following items are red, try the solutions in the
order listed.
1. Radio Communications with AutomationControl: The Sensus device is not
communicating with the headend through the base station. Go to the Radio tab and verify
that radio settings are correct. See Troubleshooting Radio Communications on page 13.
2. Configuration Loaded from AutomationControl: A profile likely has not been configured
for the device at the headend, so a system administrator needs to do this before you can
continue.
3. IED [N] Online Status: There is no communication to the IED. Verify that the IED is
connected, powered on, in online mode, and that it is configured to match the settings on the
Sensus device. If there is still no communication, the configuration settings might need to be
adjusted in AutomationControl.
“Last Signal Strength” shows the most recent transmitted and received signal strength.
◦Green = Excellent: Greater than 11
◦Yellow = Moderate: 7 - 11
◦Red = Weak: 6 or below
To improve a moderate or weak FlexNet radio signal, verify all antenna and antenna cable
connections, raise the antenna, or reposition the antenna.
