GENERAL DESCRIPTION
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 acomplete data acquisition system built in a rugged,
stainless steel enclosure. The DSM4000 performs
all of the engineering unit conversion, configurationand 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 orMSCP.
The DSM4000 utilizes advanced DSP (DigitalSignal Processor) architecture. This processor
is specifically designed for extremely fast mathfunctions and is able to rapidly convert and output
engineering unit data. The DSM4000 references
pressure-temperature lookup tables that areuniquely created for every ZOC scanner. Thispressure/temperature characterization allows
for accurate pressure measurements acrossthe full 0-60°C temperature range of the ZOC
modules, minimizing errors due to temperaturechanges. The DSM4000 module can also performzero 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, theentire system is simpler and many features havebeen added.  The DSM4000 boots significantly
faster than the DSM3400 and is completely
independent of Windows® operating system.

CONFIGURATIONSDSM4000/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. Allcommunications are through the single Ethernet
100baseT connection. For applications where theDSM4000 is too large, Scanivalve’s ERAD4000(Data Sheet #G562) 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 specificallydesigned around the demanding requirementsof a flight test application and can operate overa wide voltage input range. The Ethernet port
remains fully functional for communication, dataacquisition, setup, and diagnostics.

DSM4000 SCHEMATIC

DSM4000 HARDWARE
The DSM4000 is built around a DSP processor forfast EU conversion and throughput. There is aninternal A/D for each ZOC module, plus internal
memory for DSM and ZOC module information
storage. Ethernet 100BaseT or ARINC429
interfaces are available. Also incorporated in theDSM module is a single serial configuration port
and 5 digital I/O circuits.
Up to eight ZOC modules are connected throughsmall diameter cables that can be up to 50 feet (15meters) long.
There are no moving parts in the DSM4000. As
a result, the number of failure points has been
dramatically reduced and reliability increased.

DSM COMMUNICATION
Communication with the DSM is either Ethernet
TCP/IP or UDP, FTP or ARINC429. The
network can be set up and variables configured
via Windows HyperTerminal, a Telnet session,or through either Scanivalve’s LabVIEW
Configuration Utility or ScanTel communications

utility. A Scanivalve LabVIEW Development Kit isalso optionally available for LabVIEW 2009 (ver8.2 and up) that includes the Configuration Utility.
The IP address is user assignable and theDSM4000 is auto crossing, allowing either crossed
or straight-through Ethernet cables to be used.
All scan and calibration variables are software
configurable by the user. This includes data rate,
data format, etc.
The DSM4000 includes configuration variables tosupport a NAS (Network Attached Storage) device
allowing simple, high speed data collection.
In addition to the NAS support, the DSM4000
further takes advantage of it’s networking
capabilities by including NTP (Network TimeProtocol) support.
In addition to the Ethernet and ARINC429
connections, the DSM4000 also has an RS-232
Configuration port.  This can be used to verify
and  configure the DSM4000’s communication andconfiguration variables.

DSM4000
ON-LINE SENSORCOMPENSATION AND
CALIBRATION
When the system includes remote solenoid valves,
taking advantage of the DSM4000’s built in digital
outputs, zero-offset calibrations can be performed.
No pressure calibrator is required to perform zerooffset calibration. When actuated, the positive sideof the pressure sensor is pneumatically shortedto the reference manifold, creating zero pressure
differential across the transducer. The sensor
zero offsets from each ZOC pressure scanner arerecorded, then the zero-offset files are updated
and saved to the DSM module.
The ZOC transducers used with the DSM4000
series are factory calibrated over their fullpressure and temperature ranges. The resulting
calibration data are stored in a 280 plane pressure
temperature look-up table in the DSM module.

WIND TUNNEL / FLIGHT TEST

Each ZOC pressure scanner has a factory
installed RTD temperature sensor. As thetemperature changes, the DSP processor selects
the appropriate temperature plane, or interpolates
between planes, to correct the pressure reading.
This on-line temperature correction and quick
zero calibration correct for inherent zero drift andtemperature sensitivity allowing for long-term
6 month accuracy specifications on most ZOCmodules.

PRESSURE INPUTSZOC MODULE #7

For field calibrations of ZOC modules connectedto the DSM, Scanivalve has an accurate pressure
calibrator, model SPC4000. Included withthe calibrator is Scanivalve’s calibration utility
software, PressCAL. This allows for automatedcalibrations with the SPC4000 calibrator, ormanual calibrations with the users own pressure
calibrator or dead weight tester. PressCAL
updates the module calibration coefficient files andgenerates “as received” and “calibration validation”
reports.
