The MPS4264 is a 64 channel, intelligent, miniature pres-
sure scanner. Each MPS4264 series scanner incorporates
64 individual piezoresisve pressure sensors. In addion
to the pressure sensors, the MPS4264 integrates all of
the electronics for the analog-to-digital (A/D) conversion
process and a processor running a DSP operang system
supporng the engineering unit conversion process and all
communicaons overhead. The integral DC/DC converters
allow for a single 9-36Vdc power input. Communicaons
and data output is via Ethernet, and RS-232 communica-
ons are included for backup and troubleshoong. All 64
pressure sensors share a common reference manifold in
the center of the module. The MPS4264 module has two
pneumac valves, each servicing 32 pressure sensors. The
valve supports four logic states:
1. Measurement
2. Calibrate
3. Purge
4. Isolate
The valve state is selected by either applying control
pressures (applicable to standard units) or via soware
command (applicable to electric actuaon units).
The MPS4264 is the rst product designed by Scanivalve
to leverage the proprietary “Dynamic CALZ” funcon.
The funcon eecvely nulls the zero oset of the enre
analog-to-digital conversion process with every single scan.
This feature produces extremely stable sensor outputs and
virtually eliminates all zero dri in the system. With negli-
gible zero dri over me or temperature, the tradional
pneumac zero correcon that was frequently required is
now greatly reduced.

The MPS4264 is the inial pressure scanner in the
MPS4000 series of pressure scanners. All variants in the
series use the same sensors and valves. However, the elec-
tronics are dierent for each, and the overall form factor
is slightly dierent for each model. Because the interface,
form factor and funcon is dierent for each variant they
will be covered in separate documents. There are several
opons that, for the most part, apply to all three variants.

There are two opons for actuang the valves in the
MPS4000 series. Each one is opmal for a specic applica-
on. They are:
Pneumac “CPx” - This opon places a pneumac
input on each end of the valve. 65psi control pressure
applied to each of the ports individually determines the
posion of the valve. This is opmal for any MPS4000
module that will be replacing legacy ZOC33 modules as
the 65psi control pressures are common to both.
Pneumac “NPx” - This opon uses a pneumac actu-
ator on one end and a spring on the opposing end. The
spring is constantly driving the valve into the measure-
ment, or “Px” mode. This requires no control pressure
to scan and collect data. The opposing pneumac
control pressure required is 90-120psi.

The 64 pressure sensors in the MPS4000 series are
mounted in groups of four to custom designed ceramic
bases. Sixteen (16) ceramic bases, or “scks” are RTV’d to a
printed circuit board to create a 32 channel set. This archi-
tecture allows for a single four-channel sensor “sck” to be
replaced at the factory if needed. It also provides double
isolaon from any mechanical stresses that may be present
in the assembly.
Each sensor PCB includes four (4) digital temperature chips
and four (4) RTD’s. The RTD’s are for use in analog envi-
ronments (MPS4164) while the digital temperature chips
are used in the intelligent environments (MPS4264). The
digital temperature chips have been mapped to determine
which pressure channels they are most representave of
and are used in the pressure engineering unit conversion
process.
For every MPS4000 series module, two sensor circuit
boards are mounted back to back in the central housing.
The core of the housing is an open volume that is used as a
common reference pressure for all 64 channels. The design
places the sensors deep in the center of the module. Being

located in the center of the module protects the sensors
as much as possible from rapid temperature changes and
allows for very accurate temperature compensaon.

A single MPS4000 series module integrates two pneu-
mac valves, each supporng 32 channels. The valves are
located directly under the pressure inputs on each side of
the module. The valve supports four pneumac states in
two physical states. In the “measurement mode” pressures
are directed in from the measurement inputs to the indi-
vidual pressure sensors. The other physical state, “calibrate
mode” provides three pneumac states. They are:
1. Calibrate - A single pressure applied to the “CAL”
port is directed to the posive side of all 64 trans-
ducers.
2. Purge - Purge pressures applied to the two purge
inputs are directed out the 64 measurement ports
to clear any debris, parculate or moisture from the
inputs lines.
3. Isolate - The 64 pressure transducers are isolated
from the input lines and from the purge pressure.
The valve design is a sliding-type valve. An aluminum
shule populated with O-rings cycles back and forth
between two posions to achieve each of the physical
states. An interface between the sliding O-rings and the
aluminum staonary poron of the valve is a proprietary
compound that is extremely low fricon. The O-rings
are supported completely to prevent any deformaon
during a state change. Addionally, the valve shule is
supported on ball bearings to provide minimal fricon and
maximum support. This design allows for low actuaon
forces, minimal “scon” - meaning the actuaon forces
do not noceably increase over me, and minimum wear.
Samples of the valve design were tested to over 1,000,000
cycles without any maintenance.
As a subset of the pneumac opon it can either be a
spring-driven “NPx” version or a “CPx” bi-direconal
pneumac driven version. The advantage of the “CPx”
pneumac version is that it retains the same 65psi control
pressure that legacy ZOC33 analog pressure scanner
modules used. Two control pressure inputs are used, Px
CTL and CAL CTL. In the case of the spring-driven “NPx”
version a spring is constantly driving the valves into
measurement, or Px mode. This requires no control pres-
sures to be present for measurement and also prevents
the valve from unexpectedly or undesirably moving out of
measurement mode. The “NPx” version requires 90-120psi
control pressures which is common to the DSA line of prod-
ucts that Scanivalve produces.
All versions of the MPS4264 incorporate an opcal sensor
used to determine the posion of the valve. This can be
queried through the MPS’s soware interface. The valve
posion sensor only conrms that the valve is fully in the
measurement mode or not. It does not verify with 100%
certainty that the valve is in the calibrate mode.

The MPS4264 has seven (7) unique printed circuit boards
including two (2) exible circuits. Under the cover on
the end of the module is the IO Board (Input-Output)
which supports the power input and communicaons.
This board has all of the interface electrical connectors
including the Ethernet, power and RS-232 connectors. It
is also where the DC-DC power supply is located. The IO
Board is connected to the processor board via a exible
circuit. The Processor Board is where the modules memory
and processor reside. This board is located along the
very boom of the module inside of the lower aluminum
cover. Above the Processor Board is the A/D board which
is connected by a rigid parallel board-to-board connector.
The A/D board is where all 16 A/D converters are located
(one A/D per 4 transducers) as well as all of the mul-
plexing and sensor excitaon. The A/D board is connected
to each of the two Sensor board with two exible circuits
each. Each connecon handles a quadrant of 16 channels.
The Sensor board, as discussed earlier has 32 individual
pressure sensors mounted on ceramic bases. The last
circuit board is the valve posion sensor board. The single
valve posion sensor resides in a machined cavity of the
valve/side plate and opcally checks the posion of the
valve shule. It connects directly to the processor board
using a miniature connector.

For added convenience and exibility, all pneumac inputs
on the MPS4000 series use removable headers. There are
three separate manifolds, two headers for the 64 input
ports and a third manifold for the CAL, REF and Control
Input(s). The purge supply pressure is also applied through
each of the two measurement manifolds. The manifolds
are held on with three capve screws each. Under the
CAL/REF/CTL manifold is an ID plate that will be free when
you remove the manifold. Take care to not lose this plate
or the O-rings that are retained by it.

The MPS4264 has its power and Ethernet connecons
located on one end. The power connecon also serves as
an external trigger input and a serial connecon. LEDs are
posioned in a recessed cavity between the two connec-
tors to indicate power, link and acvity. Both the power
and the Ethernet connector are TE Connecvity “Mini IO”
series but are polarized dierently to prevent mistakes.
The connectors are latching to prevent any vibraon from
loosening the connecons.

The MPS4264 series is designed to withstand normal
industrial, ight test, educaonal, wind tunnel or similar
applicaons. The module is not water proof and it should
be protected from any splash, spray or mist. If any mois-
ture gets spilled or splashed on the MPS module, wipe it
dry immediately to prevent damage to the module.
The MPS module should not be mounted in a locaon
where it may be subjected to extreme temperature shis
or ambient temperatures outside limits dened in “Secon
1: Specicaons” on page 7. Keep in mind that the
internal temperature of the module will run approximately
15°C - 20°C warmer than ambient temperature but this is
accounted for in the calibraon tables. The temperature
specicaon is with regards to the ambient temperature.
If the MPS module needs to be used in an environment
outside of the guidelines above it should be installed in
a Thermal Control Unit (TCU). This is a rugged enclosure
incorporang a heater or cooling ngs in order to protect
the MPS module.
CAUTION! Mounng the MPS
module inadequately or in an envi-
ronment that does not conform to
the recommendaons can results in
permanent damage to the module.

Because of the design of the MPS4264, the accuracy is only
minimally impacted by the device warming up aer inially
being powered. Figure 3-4 below shows a sample 5psi
module being powered on. Pressures from 3 channels are
shown along with the module temperature. As indicated
in the graph, the rst 15 minutes of warm up produces
the only noceable change in the pressure readings. The
module can take up to 3 hours to fully warm up (in a 25°C
ambient environment) but throughout that warm-up the
pressure readings are very good. It is recommended that
the module be allowed to warm up for a 15-30 minutes
before collecng data, but this is not mandatory. If me
allows, the warm-up period should be extended to 60
minutes for most applicaons.

The MPS module is designed primarily for Ethernet
communicaons. This provides a means to congure the
MPS module as well as scan and collect data from the
module.
A serial RS-232 connecon is also supported. The serial
connecon is designed to provide emergency commu-
nicaons with the module in cases where an Ethernet
connecon cannot be established. If the internal memory
in the MPS is corrupted in any way, the serial connecon
allows the user to format the memory and restore the
operang les.

Every MPS4264 module has an RS-232 serial output. It is
available through power connector on pins 1, 2 and 3. The
wiring diagrams can be found in “Appendix F - Cable Draw-
ings and Pinouts” on page 88. Sengs for establishing a
serial connecon to the MPS4264 module are as follows:
Bits per second: 9600 BAUD
Data bits: 8
Parity: none
Stop bits: 1
Flow control: none
Once a connecon is established any of the commands
listed in “Secon 5: Soware” on page 33 can be sent to
the module. The only limitaon is that the a SCAN cannot
be iniated via the serial connecon and scan data will
never be returned via the serial connecon. Most impor-
tantly, through the serial connecon, the module’s “Group
IP” sengs, including the IP address, can be viewed and
set. The module’s internal memory can also be formaed
and restored through a serial connecon (see “Formang
the Flash Disk” on page 78 for this procedure.)
Two power/serial cables are available for the MPS. They
are:
P/N 156085: “Premium” Mini I/O male to Mini I/O male
power/serial/trigger cable
P/N 155625: Mini I/O Trigger/Power cable with ying

The cable listed as “Premium” versions use a highly-exible,
silicone coated cable that is the smallest possible diameter
(0.156”, 4mm).

The MPS4264 has one Ethernet connecon, 10/100Base-T
with MDIX auto-crossing. This is the primary means of
communicaons with the MPS. All MPS4264 modules
use a TE Connecvity “Mini I/O” series connector for
the Ethernet connecon. This is a latching connector to
prevent the connector from becoming unseated when
subjected to vibraons. Shielded Category 5e cable or
beer is recommended for all Ethernet connecons.
Several variaons of Ethernet cables using the TE Connec-
vity “Mini I/O” connector are available from Scanivalve.
Depending on the applicaon, dierent cables may be
required.
