Event Recorder for Locomotives
The Digital Event Recorder from Cattron Group International,
when used in conjunction with Accuspeed or MP 96 RCL locomotive
remote control systems (utilizing STS protocol), is an invaluable
tool for monitoring and analyzing operational data from Radio Remote
Controlled locomotives. The Event Recorder monitors and records
electrical analog, digital and pneumatic input data from the remote
control system, and the locomotive which can be retrieved and downloaded
to a computer through a wired or wireless serial link. Items recorded
include all commands from the Operator Control Unit (OCU), the remote
control inputs and outputs as well as locomotive only functions.
Samples are recorded once per second.
The Cattron Event Recorder is FRA certified and provides
220 recording channels for 96 hours synchronizing information recorded
by the radio control (RC) system with data from the locomotive.
All this is generated in a single integrated report that can save
hundreds of thousands of dollars in incident reconstruction and
liability protection. Most locomotive RC system event recorders
capture much less information and are not synchronized with the
The package includes a sophisticated Data Analysis
Software (DAS) for use on a PC which allows rapid search, chart-type
data display and a wide variety of report customization.
With an optional cellular modem interface, Event Recorder
data can be retrieved and viewed from virtually anywhere a phone
connection is available – a valuable resource for trouble
shooting with Cattron Help Desk technicians. In addition, the wireless
link allows “real time monitoring” of the RC system
and locomotive from a long distance, allowing you to see activity
as it is happening.
• Electronic hardware and software, including
pneumatic analog and digital sensors.
• Main Recorder Cable connecting Event Recorder to the locomotive.
• RS 232 MP96G2 Receiver/Decoder Cable connects the event
recorder to the RC Locomotive Control Unit (LCU).
• All LCU software
• Serial Download Interface Port (locomotive cab mounted enclosure)
incorporating a DB9 connector that enables data downloads to a laptop
• Traction Motor Current Module used to monitor Traction Motor
• Axle Drive used to monitor movement and to compute locomotive
speed and distance traveled.
• Throttle Position the state of the throttle
position is recorded along with the generator field .
• Dynamic Brake Setup input is recorded and displayed as part
of the throttle notch position channel.
• Generator Field input is recorded as one of the inputs for
• Direction of Travel (forward, neutral, and reverse positions).
Two inputs are used for this channel. One of the inputs monitors
the forward line (MU 8) while the other input monitors the reverse
line (MU 9).
• Horn this input is recorded as a high resolution event with
a resolution of 1/10th of a second. This input can be either connected
pneumatically or electrically, but not both. Typically the pneumatic
connection will be used.
• Bell this input can be either connected pneumatically or
electrically, but not both. Typically the pneumatic connection will
• PCS Open this input is used to monitor the Power (Pneumatic)
Control Switch. This recorded input is used to determine whether
an emergency condition occurred.
• Spare 1/0 Input this input can be used to monitor a 74V
• If equipped, GPS position latitude and longitude.
• Speed Rotational speed (RPM) recorded. This
measurement, wheel size, and time data are used to determine distance
traveled and speed. This input is connected to either a 20 or 60
pole axle drive.
• Traction Motor Current (Load Amps) - This
input is connected to the Traction Motor Current Module type CM
The Event Recorder system will monitor and record
serial data from the Locomotive Control Unit Computer. All serial
data is recorded with a resolution of one second. This includes
all OCU and LCU inputs and outputs, showing in each and every operating
command and resultant RC directive to the engine.
All recorded inputs are recorded with a one second
resolution, except for the Horn, which is recorded with a tenth
of a second resolution. The system will record a minimum 96 hours
of data before re-recording over the oldest stored data ('endless
loop'). The recorder utilizes Flash Data Memory (no batteries are
required to maintain data integrity) to store the event data.
Self Test Function
The Event Recorder is equipped with a continuous 'Self-Test'
function that confirms that the Recorder is functioning correctly.
An LED located on the side of the Recorder indicates that the ‘Self-Test’
function is operating.
Optional Cellular Modem Interface
The Multi-Mode Cellular Radio/Modem contains rugged
extended-temperature hardware modules that support AMPS analog,
CDMA and PCS digital infrastructures.
Note: The cellular interface does not require special
calling or data plans, however, it is the responsibility of the
end user to contract with a cellular provider. End user is responsible
for all registration and relative airtime fees.
Note: Event Recorder is ONLY compatible with Cattron
locomotive remote control systems that utilize STS protocol. Contact
Cattron engineering or your local representative for more information.
