DATA ACQUISITION
LLumistar has completed engineering
development and initial production
deliveries of a revolutionary modular
“4th generation” digital processing product
primarily designed for applications in
fixed ground, mobile and airborne flighttesting
applications.
The Lumistar LS-68-M Modular Multi-
Channel Telemetry Processing System
offers an ultra-small, low-cost, highperformance,
multi-channel COTS
solution for PCM data synchronization,
decommutation, recording and simulation
applications. Building on the legacy of the
Lumistar LS-45, LS-55 and LS-77 series of
products, and utilizing technologies
developed for the LS-28-DRSM series
products, the LS-68-M enhances the
feature sets of each of these product lines
and supplies them in a format requiring
no hardware drivers in an “OS-less”
environment. The LS-68-M utilizes a
high-speed Gigabit Ethernet interface for
primary controls and data streaming.
The LS-68-M series includes all the
traditional functions of a full rack mount
baseband telemetry processing station in
the approximate size of a 3.5” hard disk
drive. Standard capabilities include bit
synchronization, frame synchronization,
decommutation, data recording, IRIG time
and network time code reading and
generation, graphical displays, baseband
data acquisition, and Ethernet data
distribution. This adaptable product has
been found to be quite useful and

functional in many other applications
such as traditional Data Acquisition
applications with minor modifications to
the firmware personality.
The LS-68-M employs the most current
sophisticated Digital Signal Processing
(DSP) technologies. In essence, the
LS-68-M acts as a configurable network
device offering three real-time UDP data
streaming ports that can support a
multitude of PCM Frame Synchronizer/
Decommutator and Real-Time PCM
Simulator combinations. Licensing
options allow the user to use the
processing platform in a configuration
containing three PCM Frame
Synchronizer/Decommutators for one
application and then redefine the same
platform for a different application
needing two PCM Frame Synchronizer/
Decommutators along with a single Realtime
PCM Simulator.
The LS-68-M supports up to three PCM
frame synchronizers, up to two “real-time”
PCM Simulators, and an IRIG/1PPS/PTP
time synchronization engine. PCM Frame
Synchronizer/Decommutators are IRIG
106 Class I and II compliant and time
stamped. Data can be supplied to the
processing platform as single-ended or
high-speed differential clock and data
inputs. The resulting data can be streamed
via UDP in Multicast data packets. If the
user requires analog PCM inputs, the
