DSM4000/Ethernet(General,
Wind Tunnel)
The DSM4000's rugged construction, digital input and
output capabilities and fast data throughput rates are ideally
suited for many applications including wind tunnel and gas turbine
testing. One DSM4000 can support up to eight ZOC pressure scanners
and output all data, converted to engineering units at up to 625
Hz/channel. All communications are through the single Ethernet
100baseT connection. For applications where the DSM4000 is too
large, Scanivalve's
ERAD4000 may be a good alternative.
DSM4000/ARINC429(Flight
Test)
The ARINC429 version of the DSM4000 maintains all of the
features and functionality of the Ethernet version except it has
eight transmit-only ARINC429 channels in addition to the 100baseT
Ethernet port. The DSM4000's power supply was specifically designed
around the demanding requirements of a flight test application and
can operate over a wide voltage input range. The Ethernet port
remains fully functional for communication, data acquisition,
setup, and diagnostics.
The Digital Service Module, DSM4000, is
designed to interface up to eight Scanivalve ZOC pressure scanners
or EIM (Electrical Input Module) units to an Ethernet network. The
DSM4000 is a complete data acquisition system built in a rugged,
stainless steel enclosure. The DSM4000 performs all of the
engineering unit conversion, configuration and communication tasks
for the analog ZOC modules and also gives the user 5 digital inputs
and outputs. These outputs may be used to drive solenoid valves
such as Scanivalve's
DSMCPM or
MSCP.
The DSM4000 utilizes advanced DSP (Digital Signal
Processor) architecture. This processor is specifically designed
for extremely fast math functions and is able to rapidly convert
and output engineering unit data. The DSM4000 references
pressure-temperature lookup tables that are uniquely created for
every ZOC scanner. This pressure/temperature characterization
allows for accurate pressure measurements across the full 0-60°C
temperature range of the ZOC modules, minimizing errors due to
temperature changes. The DSM4000 module can also perform zero
offset correction calibrations on the ZOC modules. This feature,
along with Scanivalve's unique calibration procedures allow
accuracy specifications to be maintained for up to 6 months on most
ZOC modules.
The DSM4000 is 70% smaller and 55% lighter than its predecessor,
the DSM3400. Additionally, all moving components have been removed,
the entire system is simpler and many features have been added. The
DSM4000 boots significantly faster than the DSM3400 and is
completely independent of Windows® operating system.
