Foreword:
This manual covers the Series 9000 Disturbance Monitoring Equipment (DME). The Series 9000 provides the user with
significantly advanced capabilities in both hardware and software.
Series 9000 hardware features and benefits:
•Modular design provides greater reliability as each module operates independently.
•System design provides for unrestricted expandability.
•Units are interconnected via Ethernet (copper or fiber). Ethernet has been proven to be reliable, flexible, and easily
distributed among distant locations.
•Each module is powered directly from the station battery. This feature eliminates the need to distribute lower
voltages to other units.
•Each M9000 module contains IRIG-B circuitry to synchronize and time stamp data sampling. This feature
eliminates the need to distribute TTL timing signals among units.
•IRIG-B input format is automatically detected. This feature accommodates modulated, un-modulated, and 1PPS
inputs without the need for jumpers or connector pin programming.
•Each M9000 contains a dedicated processor. This feature provides distributed processing power throughout the
system eliminating the bottle-neck of a single CPU.
•Each M9000 contains an embedded operating system. This feature provides reliable operation and a customized
environment specific to the DME system requirements.
•The system has a fan-less design. Innovative component selection and thermal management techniques have
eliminated the need for conventional forced-air cooling. Eliminating moving parts improves reliability.
Series 9000 software features and benefits:
DME System:
•DME system software launches and runs as a daemon for highly reliable operation. Each Module starts
automatically at boot time and runs as a background process rather than being under the direct control of an
interactive user.
•XML-based configuration file provides easy import/export of data files in other formats.
•Any calculated value can be exported to a Continuous Recording data file. This feature can be used to provide
trend data for unique values.
•Fault data can be immediately pushed to the master-station via Ethernet. This feature makes fault data available
for near real-time analysis.
•All calculated values (e.g. Continuous, Analog Trigger, PMU, etc.) are derived from full transient sampled data
providing optimum resolution.
•M9kScope©feature provides real-time online viewing of waveforms and values, and calibration verification.
•Software summation of alarm outputs. This feature allows flexible alarm configurations.
•Logging of health monitoring values such as power supply voltages, temperatures, and calibration coefficients.
This feature permits review of health data history.
Master-Station:
•Web-based Master-Station provides access from any network location. This feature allows the user interface to be
served from a central location eliminating the need for version control by end users.
•User-based authentication. This feature provides logon access and privileges based on user name and password
credentials.
•Encrypted communication (SSL, HTTPS, etc.). This feature provides a high level of security to data being
transported.
•Master-Station maintains persistent communication with all Model 9000 systems simultaneously via Ethernet. This
feature eliminates data retrieval delays.
•Real-time health monitoring of entire DME fleet. This feature generates and sends an immediate alert message if
any alarm or communication error is detected at any module.
•Comprehensive analysis of all recorded data.

Section 1: M9000 SYSTEM ARCHITECTURE
The Model 9000 Disturbance Monitoring Equipment incorporates a Station-Master Computer, Station-
Master Power Supply, M9000 modules, interfaces, and various optional accessories.
The M9000 modules and Station-Master Power Supply module run in an embedded Linux operating
system. The Computer module runs with a Linux (Ubuntu Server) or in a WindowsTM environment.
The Model 9000 and Station-Master Power Supply modules are powered directly from the substation DC
battery system or from a typical secondary distribution AC voltage. The Station-Master Computer module is
powered from the Station-Master Power Supply module.
A GPS clock receiver provides a time synchronization signal to each of the Model 9000 modules. This
signal also synchronizes the sampled data coming from the M9000 modules.
Options include a display unit for local viewing of data, a keyboard with touchpad for local manual input,
and other M9000 modules and units as required.
The Model 9000 DME system is designed to provide a powerful yet versatile solution for integrated
transient fault recording (DFR), sequence of events recording (SER), dynamic disturbance recording
(DDR), and synchronized phasor measurements (PMU). Some of the key features which set this device
apart from others are:
•Continuous recording of any calculated value
•All values calculated using full transient sampled data
•Modular architecture to support centralized or distributed installations
•Embedded operating system for reliable and independent operation
•Fanless design for reduced maintenance and improved reliability
•Centrally located master server provides simultaneous communication among all M9000 modules
with the Station-Master computer, and among all Station-Master computers
•Dynamic health monitoring and transfer of recorded data
•Secure interface with web-based master server via user-based authentication, strong password
protection, and encrypted communications
•Automatic generation of system health, communication, and calibration reports

1.1 Model 9000 Module
This section describes the architecture of the M9000 module. This module performs real-time data
processing and communicates with the Station-Master computer. This is a required component of the DME
system. A Model 9000 DME system can have multiple M9000 modules.
Figure 1-2 M9000 Module
The Model 9000 modules are typically housed in a standard 5U (8.75inH x 13.25inD x 19inW) rack mount
chassis. This unit contains a CPU board, a Backplane board, Analog and Digital Input boards, and a Front
Panel LED board.
The CPU board acts as the central processing unit for this module. This board is connected to the analog
and digital input boards through the Backplane board, and to the Front Panel LED board via ribbon cable.
For complete details on this board including specifications, see Section 1.1.1.
The Backplane board is used to attach the Analog and Digital Input boards to the CPU board for the
transfer of data, control signals, and power. For complete details on this board, see Section 1.1.3.
The Analog Input boards contain input voltage dividers, current shunts, surge protection, input-to-input
isolation, and input-to-ground isolation. This board also contains precision instrumentation amplifiers,
analog-to-digital converters, and a DC calibration reference for each analog input. For complete details on
this board and its specifications, see Section 1.1.4.

4
The Digital Input board consists of voltage dividers, surge protection, input-to-input isolation, input-to-
ground isolation, and an optocoupler for each digital input. For complete details on this board and its
specifications, see Section 1.1.5.
The Front Panel LED board connects to the CPU board and indicates status of the M9000 module.
This board contains eight LEDs which display solid colors of red, green, or yellow and can also blink or
warble to indicate various states of the M9000 module. Below are the status definitions for the M9000
module:
•ON LINE
This LED indicates the operational status of the M9000 module.
o●Green:
This indicates a normal condition. The M9000 module processor has booted properly, the
firmware is running, and the configuration file has been successfully applied.
o●Yellow:
This indicates the M9000 module is in Internal Calibration mode. During this time, the
recording and trigger functions are suspended.
o●Red:
This indicates an alarm condition. The M9000 module is not recording.
o●Off:
This indicates an alarm condition. The M9000 module is not recording. It is in the boot-up
process or is powered off (see POWER below).
•TRIGGER
This LED indicates the condition of trigger limits.
o●Green:
This indicates a trigger condition. A trigger condition means one or more analog
measurements exceeded a trigger limit or one or more digital inputs transitioned to an
abnormal value or state. This LED remains green until the Station-Master computer
requests the triggered data.
o●Yellow:
This indicates the M9000 module is transferring triggered data to the Station-Master
computer. Once transfer is complete, the LED resets to Off.
o●Off:
This indicates no trigger conditions are being processed.
•1PPS
This LED indicates status of the time synchronization.

5
o●Green (Blinking):
This indicates a normal condition. Blinking green indicates the M9000 module is
synchronized to the IRIG time source within a tolerance of one microsecond.
o●Red (Blinking):
This is an alarm condition and indicates one of two conditions:
▪If the blue IRIG IN LEDs on the rear of the M9000 module (Figure 1-3) are ON, the
module is synchronized but to a tolerance greater than one microsecond
▪If the blue IRIG IN LEDs on the rear of the M9000 module are OFF, the IRIG time
signal is not detected.
•COMMUNICATION
This LED indicates the status of the Ethernet communication between the M9000 module and the
Station-Master computer.
o●Green:
This indicates a normal condition and indicates that communication with the Station-Master
computer is normal.
o●Yellow:
This indicates an alarm condition. The network link is good, but communication with the
Station-Master database is down.
o●Red:
This indicates an alarm condition. The network link to the Station-Master is down.
•POWER
This LED indicates the status of the M9000 module power supply voltages. These voltages have
preset factory limits and are not field changeable.
o●Green:
This indicates a normal condition. All power supply voltages are good.
o●Red:
This indicates an alarm condition. One or more of the six power supply voltages are out of
limits.
•DISK
This LED indicates the status of the M9000 module local storage.

6
o●Green:
This indicates a normal condition; the disk free space is normal.
o●Red:
This indicates an alarm condition. The disk free space is less than 20%.
•TEMPERATURE
This LED indicates the temperature status of the M9000 module
o●Green:
This indicates a normal condition, the DFR temperature is normal.
o●Red:
This indicates an alarm condition, the DFR temperature is either over or under the limit
settings.
o●Yellow:
This indicates an alarm condition, the DFR temperature is OK but is within 10°C of the
high limit.
•(UNUSED)
This LED is reserved for future use.

The rear panel of this module has the following features:
Figure 1-3 CPU 9000 Rear View
•Power Indicator
This green LED indicates that the power switch is in the ON position and the fuse is good.
•Fuse
This fuse protects the board from excessive input current.
•On / Off (1 / 0) Switch
This switch is used to control power for this module.
•Input Power
This connection is used to supply power to the module and is a required input. It accepts voltage
from the station battery and provides isolation and surge protection. The standard input
configuration is 125VDC or 120VAC. The input can also be factory configured to accept 250V or
48V DC input voltage.
•Event Power
This optional connection is relevant only when the DAU chassis contains a Digital Input module. It
serves two functions. One function is to monitor the presence of external Field Contact Voltage.
The other function is to apply Field Contact Voltage to be supplied from the Digital Input terminals.
Both input lines (+/-) pass through internal fuses and then routed to the digital input boards (see
Section 1.1.5).

8
The monitoring function measures the potential across these two terminals and the system will
indicate a Power alarm when it is below 40Vdc.
•Remote Power Off
This optional connection is used to control power to the module from a remote location. Applying a
voltage between 5VDC and 200VDC to this input disables the DC output.
•Ports 0 and 1
Port 0 is used for low level communications to the CPU board. It is used only when updating the
Linux file system or when performing advanced troubleshooting.
The Port 1 connection is not used.
•USB
This connection is not used.
•ETH0 / ETH1
These CAT5 connections are used for communication between the module and the Station-Master
computer.
•ETH2 / ETH3
These optional fiberoptic LC type connections are used for communication between the module
and the Station-Master computer.
•SYNC OUT
This connection provides a synthesized un-modulated IRIG signal.
•IRIG IN
These two BNC connections are electrically paralleled and act as an input to the module. They also
allow the IRIG signal to be daisy-chain connected between modules. The module automatically
detects whether the input is modulated or un-modulated.
•IRIG IN LEDs
The lower blue LED blinks to indicate IRIG activity. The upper blue LED blinks at one pulse per
second (1PPS) when the M9000 module is synced to the IRIG input.
•Analog Inputs (AI)
These inputs accept AC or DC inputs. There are four input terminals labeled C, I, V2, and V1.
These inputs are used as follows:
oV1:
This terminal is used for voltage inputs with full scale range from 41Vrms to 400Vrms.
oV2:
This terminal is used for voltage inputs with full scale range from 1.5Vrms to 40Vrms.
