Optimus System Processor manages a configurable measurement solution that provides high precision and
throughput data for up to 2048 measurement channels. Pressure is measured with ESP Miniature Pressure
Scanners or the new MicroScanners, and then converted to a digital value within the mSDI Miniature Scanner
Digitizer Interface units. Engineering Unit measurement values are calculated within the Optimus System
Processor and reported via Ethernet at data rates up to 1GBit/second. Users preferring to calculate engineering
unit data in their own host computer can receive measurement values in binary format via the Ethernet interface.
System components include PCU Pressure Calibration Units to provide precise pressure calibration and
performance verification information prior to start of test. Fiber Optic Interface Units, OFIU’s, combined with the
mSDI utilize single fiber cable to provide noise free communication between the pressure scanners and system
processor.

Pressure Scanning System
SYSTEM INTRODUCTION
The Optimus Data System provides accurate high speed pressure acquisition of ESP and MicroScanner
Pressure Scanner data for windtunnel test and measurement applications. The system is configurable for low
speed, transonic, supersonic and hypersonic windtunnels with low and high channel count requirements.
Pressure Scanners are placed within or near the test object and connected to the measurement points on the
test object using flexible tubing. Multiple scanners are connected to the mSDI Miniature Scanner Digitizing
Interface which can be placed within the windtunnel model, sting or any convenient location up to 150 ft away
from the scanners. The mSDI and 8491 Remote Power Supply, RPS, combine to provide precise excitation
voltage to the scanners using individual scanner excitation feedback with active compensation. Each mSDI can
support up to 8 ESP or MicroScanner pressure scanners in any combination. Analog to Digital conversion takes
place within the mSDI and is transmitted via fiber optic cable to the OFIU fiber optic interface units within the
Optimus System Processor. Each OFIU supports one mSDI. Up to 4 OFIU/mSDI are supported with each
Optimus. Ethernet interface to the host computer can provide engineering unit value data or binary data for
users preferring to perform engineering unit calculation within the host computer.
Pressure Calibration Units provide precise reference pressures to perform on-line calibration or provide
verification pressures before testing is performed. Span calibration of ESP DTC-Style scanners before use
provides the highest available accuracy.
Optimus provides a convenient upgrade path for 8400 System users by utilizing the same command set and
offering compatibility with 8400 components such as: 8432/8433 Pressure Calibrators, 8491 Remote Power
Supplies, 8404 Remote Processors and ESP Pressure Scanners. Upgrades and Service Life Extension Plans
are also offered for various 8400 system components to achieve maximum performance.
Optimus is compatible with the latest MicroScanner and Gen-2 ESP pressure scanners as well as legacy ESP
scanners manufactured by the former Pressure Systems Inc ., which is now the Aerodynamic Research Group
within Measurement Specialties Inc. , a TE Connectivity company.

Optimus
Pressure Scanning System
OPTIMUS SYSTEM PROCESSOR (OSP)
The Optimus System Processor (OSP) is the central data acquisition and control unit of the Optimus Pressure
Scanning System. Configured for 19 inch rack or bench top installation, the OSP can support up to 32 pressure
scanners for a total of 2048 measurement channels. Ethernet interface allows direct host interface, networked
host interface, and expansion beyond 2048 measurement channels.
Optimus Fiber Optic Interface Units (OFIU’s) are installed inside the OSP to communicate with the Miniature
Scanner Digitizing Interface (mSDI). A minimum of one OFIU is required for system operation and up to four
OFIU’s can be installed within one OSP. The OFIU’s can be factory installed at time of system production, or
can easily be installed by the end user.
Data acquisition is initiated by the host computer which instructs the OSP to: acquire only one data point per
request, stream data at specified rates, or send data upon receipt of a hardware trigger. Data output is flexible
and can consist of multiple averages with engineering unit output. Data can also be delivered in raw binary
format for users who prefer to perform averaging and or engineering unit calculations within the host computer.
Maximum performance of Optimus is achieved with current production ESP and MicroScanner pressure
scanners. Accuracy, throughput, cable length and other limitations may exist with previous generations of ESP
pressure scanners.
OPTIMUS FIBER OPTIC INTERFACE UNIT (OFIU)
The Optimus Fiber Optic Interface Unit (OFIU) is a system component inside the OSP. It is a module that
provides noise free data communication via 62.5 micron multimode fiber cable between the OSP and the mSDI
scanner interface. The fiber optic cable extends the OSP to mSDI distance. The thin flexible cable lets users
place the mSDI within windtunnel models and bring data through the sting and perform simultaneous pressure
and force balance measurements.
Each OFIU interfaces with one mSDI. A minimum of one OFIU is required for system operation with a maximum
of four OFIU’s able to be installed inside each OSP. The cable termination is via industry standard ST fiber optic
connectors which are pre-installed within each OSP. The number of OFIU’s to be installed is specified at time of
order. Existing systems can be expanded by the user with the installation of additional OFIU’s.
MINIATURE SCANNER DIGITIZING INTERFACE (MSDI)
The Miniature Scanner Digitizing Interface (mSDI) is the connection point for the cables leading to the pressure
scanners. The mSDI provides regulated power to the scanners, facilitates excitation feedback measurement and
conducts analog to digital (A/D) conversion at high data rates.
The small size and low power dissipation of the mSDI makes it ideal for locating inside of most windtunnel
models. Cross sectional area was designed to match the ESP-64HD scanner, allowing the mSDI to be placed
in-line with the pressure scanners for maximum channel density.
Data interface from the mSDI to the OFIU is via the OFCA fiber optic cable terminated on industry standard ST
connectors. Power is supplied from the 8491 Remote Power Supply (RPS) which in turn is distributed to each
pressure scanner via the mSDI. The mSDI connects to the ESP pressure scanners with the OSCB cable, which
can vary between 6 inches and 150 feet in length when using the latest Gen-2 version of ESP pressure
scanners. Pressure scanner installation can vary between one 16-channel scanner and eight 64-channel
scanners, all on different length OSCB cables. OSCB cables utilize standard miniature sub-D 15 pin connectors
to mate with all standard ESP pressure scanners.

Pressure Scanning System
REMOTE POWER SUPPLY (RPS)
The Remote Power Supply (RPS-Model 8491) provides precisely regulated power to the mSDI which in turn
distributes the power to the connected pressure scanners. +12, -12, and +5VDC power rails are monitored and
automatically adjusted to ensure proper voltage levels are maintained, even when power demands vary from
temperature variations, cable length variations or any mixture of legacy and new scanners.
The RPS connects to the mSDI with the 8476 cable, or user manufactured equivalent, which can vary between
1 and 300 ft in length. The RPS uses excitation sense feedback to constantly monitor and adjust power to
ensure proper excitation signals to the scanners under different configurations. This monitoring and adjustment
also corrects for temperature induced changes in cable resistance during use.
The RPS is configured for 19 inch rack mount installation or bench mount use. Each RPS can support two
mSDI. Multiple RPS are required for installations with more than two mSDI. The 8476 cable can connect to one
mSDI or the OFCY (Y-Cable) can be used to split the 8476 power to two separate mSDI.
The RPS is a Legacy 8400 System Product. Users with existing 8400 Systems considering upgrading to
Optimus may require a minor modification to their existing RPS to be compatible with the latest generation of
pressure scanners.
PRESSURE CALIBRATION UNIT (PCU)
The Pressure Calibration Unit (PCU) is a high accuracy servo-controlled pressure generation instrument. Its
function is to provide accurate and precise pressure to the ESP Scanners for the purpose of performing
calibration or pre-test verification. System configuration allows the user to pre-program the pressure set points
to use during calibration. When commanded to start a calibration sequence the PCU sets and reports the exact
pressure applied to the pressure scanners. Use of PCU’s can provide system accuracy better than +/- 0.03%
Full Scale. The pressure range of the PCU is selected to match the pressure range of the scanner for most
accurate calibration. The system is designed to use multiple PCU’s in parallel to perform rapid and precise
calibration for configurations using a variety of measurement pressure ranges during one test. Up to twelve
different pressure ranges and a total of 2048 measurement channels can be calibrated in parallel in
approximately 90 seconds.
Each PCU uses externally supplied source pressure brought in from the pneumatic backplane of the Remote
Processor (RP) then precisely regulates and maintains the desired calibration pressure. Users interface to the
PCU’s via software commands to the OSP. Typical calibration consists of 2-5 pressures set in succession over
the span of the pressure scanners measurement range. The PCU’s are also used to perform an Auto Accuracy
Test (AAT) where the user sets specific pressures and verifies accuracy of the ESP Pressure Scanners.
The PCU is also available as a measurement-only instrument called the Pressure Standard Unit (PSU). The
PSU has the same physical configuration as the PCU, incorporates the same high accuracy measurement
sensor but without the controller hardware. The purpose of the PSU is to measure and continuously monitor
important windtunnel pressures not associated with the primary test object measurement. Barometric pressure,
tunnel static pressure and tunnel wall pressure are examples of measurements made with PSU’s. The PCU can
also operate in measurement-only mode, like the PSU, allowing it to be used to make measurements while not
being used to set pressures.
PCU’s and PSU’s are Legacy 8400 System Products. Users with existing 8400 Systems considering upgrading
to Optimus may use existing PCU/PSU’s without modification. Units older than 10 years are recommended to
have the original battery backed RAM (BB RAM) replaced and consider a Service Life Extension Plan (SLEP) to
refurbish damaged or heavily used units.

REMOTE PROCESSOR (RP) AND LOCAL SLAVE (LS)
The 8400 Remote Processor (RP) and Local Slave (LS) are rack mounted interfaces for the PCU and PSU.
They provide complete pneumatic, electrical and communications interface for the PCU’s and PSU’s. Up to four
PCU/PSU’s can be mounted within one RP. All pneumatic connections are conveniently routed thorough a
unique pneumatic bus on the backplane of the RP, allowing convenient and automatic pressure connection
between the PCU/PSU’s supply pressure and output to the pressure scanners.
The RP is a rack mounted instrument that can be mounted near the OSP, or remotely near the pressure
scanners. Mounting the RP closer to the pressure scanners reduces the length of the pressure calibration lines
which may improve calibration speed due to reduced pressure settling time in the large volume associated with
long calibration lines.
The RP communicates to the OSP via serial RS-485 using the 8484 cable and contains an internal power
supply for AC input compatibility. Up to three RP’s can be connected to one OSP for a total interface of 12
PCU/PSU’s.
A Local Slave (LS) can be connected to the Remote Processor to expand the number of PCU’s supported by
the system. The LS receives power from the RP and communicates to the OSP through the RP. As such it is
located in close proximity to the RP.
The RP, LS and associated cables are Legacy 8400 System Products. Users with existing 8400 Systems
considering upgrading to Optimus can use properly operating units without modification or service requirements.

SYSTEM CABLES
The Optimus System incorporates a variety of function-specific cables to achieve highly accurate, fast and
reliable operation for a broad range of windtunnel types. Each cable has been carefully selected and designed
to achieve specific functions common to most windtunnels. Detailed cable diagrams and cable design
assistance are available to users desiring to manufacture custom cables to meet requirements unique to their
own installation. It is recommended to have one complete set of factory produced cables for troubleshooting
purposes. The following describes the function of each cable, starting with connections at the pressure
scanners.
OSCB – Optimus Scanner Cable
The OSCB connects ESP pressure scanners to the mSDI scanner interface. It is available in lengths from 6
inches to 150 ft. Any combination of cable lengths can be utilized since the RPS automatically adjusts system
power load and pressure scanner excitation on a per-scanner basis. The OSCB is an improved version of the
PSCB cable with specific shielding and pin locations to minimize power to signal interference. The connector
gender has been changed at the mSDI to prevent accidental reversal of the cable while maintaining standard
ESP/MicroScanner pressure scanner connector compatibility. A PSCB cable may be modified to functional
equivalent of OSCB cable with connector change for lengths up to 90 ft. OSCB cable has one additional shield
wire connected at scanner end which provides improved performance for lengths over 90 ft.
OFCA – Optimus Fiber Optic Cable
The OFCA provides noise free data communication between the mSDI scanner interface and the OFIU fiber
optic interface located within the OSP. Industry standard, reliable metallic ST connectors are used at both ends
of the cable. Full duplex communication between the mSDI and OFIU allows the use of just one fiber to
simultaneously transmit and receive reliable high speed communication between the two system components.
The mSDI and OFIU communicate at 1310 and 1550 nm via 62.5 micron multimode fiber, allowing existing 8400
users to utilize existing 8474 fiber optic cables without modification. We offer OFCA cables in discrete lengths
up to 91 meters (300 ft). The system has been verified for use with cables up to 1 kilometer.
8476 Power Cable
The 8476 provides accurate, regulated power to the mSDI from the RPS. It is available in any length between 1
ft and 300 ft. Existing 8400 users can use existing 8476 cables without modification.
OPCY Y-Cable
The Y-Cable connects the 8476 cable and mSDI. It functions as a splitter to expand RPS power to two separate
mSDI. Excitation feedback to provide the required precise scanner excitation is maintained with this cable
design. The two legs of the Y-Cable can be different lengths with an overall length limitation of 6 ft. (2 meter
designation also available).

MECHANICAL MODELS
MM – Mechanical Models
Anodized aluminum mechanical models, MM, of ESP pressure scanners and mSDI interface are available to
assist with model installation. These items allow the functional ESP and mSDI instruments to be used for
existing testing while providing mechanically equivalent units to assist with tubing and wiring installation of future
test models. Upon completion of tubing and wiring connections the transition to test configuration is quick and
convenient. The mechanical models are removed and the functional instruments can be installed and rapidly
connected to precisely located quick disconnects plates and cables.
SOFTWARE COMMANDS & 8400 COMMAND SET COMPATIBILITY
The Optimus utilizes much of the same command set as the 8400 System. Commonly used 8400 commands
have been preserved. Most 8400 users will be able to convert existing installations with a minimum of software
investment. A list of currently implemented commands is available. Command list review with a factory
applications engineer is recommended for 8400 users planning to re-use existing software.
UTILITY SOFTWARE
