RADBASE shownwith 2 and with 8A/D’sGeneral Description

RADBASE. Each A/D supports one 16, 32, or 64
channel ZOC pressure scanner or one ZOCEIM.

The state-of-the-art DSP technology is at the heart ofour new E-RAD4000 pressure measurement system.
Located inside the RADBASE is a programmabledevice, (Digital Signal Processor, DSP) capable ofextremely fast math functions that operate on the data
stream in real time. All measurements are converted
into Engineering units.

The output of the RADBASE is Engineering units via
a small diameter Standard CAT5 Ethernet cable. TheRADBASE has the pressure sensor calibration datastored in memory and converts the digital data to temperature compensated Engineering units.

Advantages of DSP technology:

Data are then output Ethernet TCP/IP 100 baseT to ahost computer.

•Boots up quickly•
Real Time Operating System•
Low Data Latency
The RADBASE DSP processor utilizes a pressure
temperature look-up table to compensate the pressure sensors for temperature changes, thus reducing
thermal errors. It also can control the actuation of an
external calibration valve via the RDS3200 module
to perform on-line zero offset corrections. Long term
accuracy is achieved for up to 6 months before recalibration is required.

Applications

This new Ethernet remote A/D system is a turnkeypressure measurement system that combines the fieldproven RAD3200 with Ethernet TCP/IP. E-RAD4000
system is capable of maintaining its performanceeven as computer technology and operating systems
upgrade. E-RAD will work on any hardware platformthat has an Ethernet port, thus minimizing the user’s
future interface risks.

A feature of the system is that each A/D and each
ZOC pressure scanner has an ID chip installed. During power up or on demand, the RAD can read theZOC ID chip information -model, pressure range, serial number, number of channels, date of manufacture
and calibration date.

Typically, the RADBASE would be located inside awind tunnel model or other space limited location inclose proximity to the ZOC pressure scanners.
For small models with low number of pressure channel requirements, the RADBASE can be minimal size
to fit into the model. For large systems the E-RADsystem can be expanded with modular A/D modules
or multiple RADBASES for up to 2048 pressure channel system.

The E-RAD system is modular and allows up to 8
each A/D (16 bit) modules to be plugged into one

E-RAD4000 Remote A/D OperationThe E-RAD4000 is a complete pressure measurement system consisting of a RADBASE4000 baseunit, 1 to 8 A/D’s, and ZOC pressure scanners. It is
designed to be installed inside or in close proximity
to a wind tunnel model. By digitizing the transducer
analog signals in the model, potential noise errors due
to long cable lengths are eliminated.

1) RADBASE4000 is the base unit that incorporates
the communication and power connectors, and realtime DSP operating system. Communication and data
throughput are via a small diameter Ethernet cable.
Power required is +/-15Vdc and +5Vdc. Multiple RADbases can be part of one E-RAD system.

RADBASE4000 with 8 RAD A/D3200s2) RAD A/D 3200 is the modular A/D portion of theE-RAD system. The RAD A/D’s are temperaturecompensated. Each 16 bit A/D module supports one
ZOC pressure scanner or one Electrical Input Module(ZOCEIM). Additional A/D modules can be plugged
into the RADBASE to easily expand from 1 to 8 A/D’s(512 channel system).
Each A/D has an ID chip to identify itself with its serial
number, date of manufacture, date of last calibration,and temperature coefficients. The analog cable between the RAD A/D and a ZOC pressure scanner may
be up to 15 feet (4.61m) maximum in order to maintain maximum scanning speed. Contact Scanivalve
for longer cable lengths.

RAD A/D3200 MODULE
3) RDS3200 (Remote Digital Switch) is a plug in module that incorporates 8 software controlled switches.
These switches can open or close relays that operatesolenoid valves or other devices. Scanivalve’s model
MSCP3200 miniature solenoid control pack contains
3 solenoid valves. It can be operated by the RDS3200
and is small enough to fit inside a wind tunnel model.
User supplied power is required for this feature(24Vdc std, 5 & 12Vdc optional and must be specified
at time of order). Up to 8 RDS modules can be usedon one RADBASE.

E-RAD System

E-RAD Command Set

The E-RAD Ethernet pressure measuring system
consists of:• Optional SPC pressure calibrators

E-RAD firmware contains user commands and configuration variables that are installed in the RADBASE4000. The commands permit a user to control
all functions of the RAD, including control of external
devices when the RDS3200 digital switch is connected. The configuration variables permit a user to define
communications, RAD module setup, identification,scanning EU conversion, and data output. Because
the pressure calibration files for the ZOC pressure
scanners are stored in memory, all Engineering Unit
conversion occurs in the RADBASE4000.

• Optional NAS network data storage(user supplied)

Variables for any test configuration may be saved to a
file for future use.

The E-RAD system allows for the RADBASE, A/D’sand ZOC pressure scanners to be mounted inside awind tunnel model. Data are converted to EU in theRADBASE and exit the model and sting via a small
diameter standard CAT5 Ethernet cable connecting tothe user’s host computer or network.

Scanning may be initiated through a software orhardware trigger for synchronization with other datasystems.

• 1 RADBASE4000 (for each 512Px)• 1 to 8 each RAD A/D per RADBASE• 1 ZOC pressure scanner per RAD A/D• Cables, power supplies, & accessories

The E-RAD robust turnkey pressure measurement
system will operate with any hardware platform thatcan communicate Ethernet TCP/IP. This would include PC’s, MAC’s, VXI systems, or any user host ornetwork
Large and expensive data systems are no longer
required for fast accurate data measurement andacquisition. The cost involved to buy into this technology is now relatively low and affordable by universities
and small research facilities.

An option for the E-RAD4000 system is a Configuration utility (includes  LabVIEW® 2009 runtime engine)
and a Scanivalve Software Development Kit forLabVIEW® 2009 for users who want to write their own
detailed data acquisition program in LabVIEW®.
Direct communication to the RADBASE can also bemade using ASCii commands via Telnet, WindowsHyperTerminal or Scanivalve’s ScanTel utility.
A free program for performing on-line calibration of theZOC pressure scanners can be downloaded from theScanivalve website (PressCal).

General Description

ZOC Pressure Scanner Upgrades

The ZOC (Zero, Operate, and Calibrate) pressure
scanners contain piezoresistive pressure sensors inarrays of 16, 32, and 64. An RTD is factory installed tosense the ZOC pressure scanner’s temperature. Theanalog pressure sensor and the RTD data are digitized in the RAD and data converted to temperaturecorrected Engineering Units.

All ZOC pressure scanners (ZOC22B, ZOC33,ZOC17, ZOCEIM) are manufactured with an ID chip
installed. Legacy ZOC pressure scanners may beupgraded with an ID chip at Scanivalve’s factory.
ZOC pressure scanners may also be used without an
ID chip installed, but will lose the auto configuration
capability.

Also incorporated into each ZOC pressure scanner
is a pneumatic calibration valve that allows for sensor rezero or multipoint calibrations on demand. Thiscalibration valve also permits purging of the pressure
input lines of condensation and contaminants. Available ZOC pressure ranges are 5 inches H20 up to750 psi full scale.

Upon power up, the RADBASE automatically interrogates the ZOC ID chip and auto selects the appropriate ZOC calibration coefficients for each moduleconnected on the systevm.

E-RAD4000 System Network
Data are transmitted via Ethernet TCP/IP or UDP
100baseT in Engineering Units using ASCii or binary
format. Data are transmitted at 625 Hz/channel maximum. This unloads the user’s host from making thesecalculations. This architecture design enhancement
allows for universal operation on all hardware platforms and operating systems that have an Ethernetport.
Scanivalve’s optional Configuration Utility  (includesLabVIEW® 2009 runtime engine) is designed to assist
a user in configuring the RADBASE. Also available isa Scanivalve Software Development Kit for LabVIEW®
2009 for users who want to write their own detailed
data acquisition program in LabVIEW®. Examples areprovided. This Development kit includes the Configuration utility.
