PAK MKII FRONT END
DYNAMIC
The PAK MKII front end is a compact, highly integrated and versatile system for the measurement of dynamic parameters, ranging from slow bandwidth thermocouples, through medium bandwidth strains and accelerations, to high bandwidth sound. It is based on a well established concept with the VMEbus as its central conceptual tier. Mainframes are available in 5 sizes containing 2, 3, 4,
6 and 10 VMEbus slots and can be synchronized together operating as one PAK
MKII although geographically separated by 1000m or more.
3 different VMEbus based System Controllers are available to best suit the above
Mainframes. These boards provide either a 100BaseT or a 1000BaseT Ethernet interface to a Workstation. Wireless LAN is also provided on all except the largest
System Controller. Battery backup is supplied on all Mainframes.
A MiniTerminal provides a bright LED display as a practical solution to show test information as well as to input commands from a User. It connects to anyone of the above System Controller boards.
Although the VMEbus is flexible, a more compact tier of modularity is required for signal conditioning amplifiers. A Sub-VMEbus concept was therefore devised where 4 signal conditioning Modules fit onto a special VMEbus board which provides the mechanical and electronic infrastructure for these Modules. Typically each Module contains 4 channels with some containing 8 channels and others
1 or 2. Thus using this average of 4 channels per module, a 2-slot Mainframe contains an average of 16 channels and a 10-slot Mainframe 128 channels. A limitless number of measurement or control channels is achieved through the synchronization of Mainframes to form SyncLink Clusters and SuperClusters.
A wide range of Modules exists to measure parameters such as voltage, acceleration, pulse-period, sound, strain, force, pressure, displacement, temperature, digital audio, CAN, GPS and IRIG. This offers the User complete freedom when configuring their measurement system. A Module which provides an analog output signal is also available. All Modules can, subject to certain operational precautions, be removed or inserted into a Mainframe in order to satisfy a particular test’s needs.
On a smaller scale, if necessary, SubModules provide the final interface between a Module and a specific sensor. An example of this is when both a Pt100 temperature sensor and K-type thermocouple are plugged into the same Module, each with its specific signal and connector needs.

CERTAINTY
The PAK MKII concept was established in 1989 and is based on recognized hardware standards such as VMEbus, IEEE 1101.2 and Ethernet whilst other standards such as PMC and IEEE 1588 followed later. These standards contribute to the longevity of the User’s investment as it allows the PAK MKII design to withstand fluctuations in technology and changing customer requirements.
This is due to these standards’ common use in aerospace, military as well as professional instrumentation and control systems. Through this, PAK MKII’s designers and developers are provided with a consistent framework whilst ensuring that modularity is maintained in the years to come.
Due to this innovative concept of modularity, all VMEbus boards and Modules can be used in all Mainframes, subject only to the data rate and electrical power limitations of the System Controller and Power Supply boards. The uniformity in design of all Mainframes makes them equally suited to both mobile and laboratory applications thereby offering the User exceptional flexibility. Finally, the comprehensive design concept also allows for easy upgrading to more of the same or newer technology Modules, VMEbus boards or Mainframes with minimal disruption and loss in investment.

The highest available levels of modern technology are used in the electronic design of the PAK MKII. Components are carefully selected according to the criteria of functionality, performance and size. Mechanical construction is also carefully executed to provide resistance to shock, vibration and thermal stress whilst retaining an attractive appearance.
The PAK MKII makes use of a professional real time operating system, namely
Windriver’s VxWorks, on all its System Controllers. This allows considerable software flexibility when integrating new applications and third party VMEbus boards. Consequently, new applications could include EtherCAT, telemetry, extended web server and standalone operation.
Being able to operate standalone without a Workstation, is particularly significant as it allows the PAK MKII to handle harsh or confined mobile environments where a Workstation cannot be used. Another standalone requirement exists in control applications where failure in the link to the Workstation could cause severe problems. In such cases the PAK MKII’s internal operating system ensures logical and safe decisions.
The PAK MKII was awarded the International Forum (iF) Product Design Award in 2006 for both functional and aesthetic design. The iF Design Award is one of the world’s oldest international design competitions where entrants are evaluated on design quality, workmanship, choice of materials, degree of innovation, environmental compatibility, functionality, ergonomics and aesthetic appeal.
GPS, CAN and other non analog measurements are made within the PAK MKII front end, allowing optimal synchronization with analog measurements. Each time a GPS or CAN message is received, it is time-stamped against the same clock which samples analog input and output data. The normal time-stamp resolution is 5 µ s whilst a tighter time-stamp resolution of 50ns is used in time-critical applications.
PAK Software is tightly integrated with the PAK MKII front end thereby forming the PAK MKII measurement system, a formidable partnership in measurement management and performance. This can be illustrated by PAK keeping control of high channel counts through the use of special setup utilities during the preparation of the measurement, as well as the supervision of signals during the operation of the test. For instance, a control window comprehensively visualizes all active
Modules on the Measurement Workstation, showing the strength of each incoming signal. The added User’s benefit of simply monitoring the Workstation without having to consult the front end, improves control of the hardware configuration.

PAK MKII FRONT END t3 t2 t1 t4 t5
The PAK MKII system takes the concept of modularity to an unusually deep level with it being repeated in 5 sub-system levels or tiers, namely
SubModules, Modules, VMEbus boards, Mainframes and SyncLink Clusters.
These 5 tiers of PAK MKII modularity are collectively known as 5tModularity™ and are symbolized by circles defining 5 regions as shown on page 5.
The core of any modular concept should be powerful and versatile but most importantly stable and sustainable. For some 25 years after its launch, VME is still flourishing and is associated with at least 30 other standards. It is predominantly used in aerospace, military, industrial, measurement, control and research applications. It was for this reason that the VMEbus was chosen as the core of the PAK MKII concept. The VMEbus tier is known as tier 3 or abbreviated as t3.
Although the VMEbus is flexible, a more compact tier of modularity is required for signal conditioning amplifiers. A Sub-VMEbus concept was therefore devised where 4 signal conditioning Modules fit onto a special VMEbus board which provides the mechanical and electronic infrastructure for these
Modules. This board belongs to the Signal Conditioning series and currently is the SC42.
Modules are easily inserted and extracted through the front panel of the SC42 allowing Users the flexibility of self configuring the measurement system for a particular test. Currently there are 15 different Modules available, each addressing a particular sensor type. This is tier 2 or t2.
A SubModule is sometimes required to provide a special interface to an individual sensor. An example of this includes using K thermocouple and
Pt100 sensors on the same Module to measure temperature. SubModules are thus used to further personalize a Module. This is tier 1 or t1.
Flexibility is also required in a Super-VMEbus tier. Different sized Mainframes optimize the number of channels to be measured whilst at the same time offer freedom to accommodate additional boards at a later stage. In this way the PAK MKII grows according to the User’s demands. 5 Mainframe sizes are available, each with a different number of VMEbus slots, namely 2-slot
(MF02), 3-slot (MF03), 4-slot (MF04), 6-slot (MF06) and 10-slot (MF10). This is tier 4 or t4.
As all Mainframe slots are VMEbus slots, any VMEbus board can fit into any slot of any Mainframe, once again illustrating the sustainable concept on which the PAK MKII is based. The choice of VMEbus System Controller for a Mainframe depends only on its data processing ability and the size of its power supply.
A SyncLink Cluster concept was developed to allow any number of
Mainframes to be synchronized together, effectively allowing numerous
Mainframes to operate as one virtual Mainframe. This is called a Cluster and is tier 5 or t5.
These Clusters are useful as they reduce sensor cable lengths, increase the data rate coming from a test, allow for greater geographical reach and accommodate a limitless channel count. Such a Cluster would normally demand higher data rates for which Gigabit Ethernet is implemented.
This concept has additional advantages. For instance as part of a deliberate strategy, Users may wish to purchase smaller Mainframes for mobile tests and combine them from time to time in order to measure the increased channel count of larger mobile or laboratory based tests.

The beauty of the PAK MKII’s 5tModularity™ lies in its personality. Each PAK MKII is unique to its User through its own configuration. Differently sized PAK MKII
Mainframes are populated with VMEbus boards and Modules of the User’s choice to suit their individual test requirements. SubModules as well as Accessories, such as the
MiniTerminal and SeatFrame, provide additional functionality and ensure the User of an easier, more accurate, measurement environment. These PAK MKII Components and other Accessories are mentioned below with a reference to the pages on which they are discussed. The principle components are shown on the adjacent page.
There are 5 Mainframes namely MF02, MF03, MF04, MF06 and MF10. Each comprise of between 2 and 10 empty VMEbus slots that can be populated freely, restricted only by the size of the System Controller and Power Supply. The System Controller and
Power Supply are contained on a single VMEbus board for MF02 to MF06 and on two boards for MF10. These boards fit into slot 1 of MF02 to MF06 Mainframes and slot 1 and 2 of the MF10 Mainframe.
The range of Mainframe sizes offers Users flexibility when choosing the number of slots needed. Some of these options include:
• One large Mainframe which can be used for both mobile and laboratory testing
• Two medium sized Mainframes which can be linked together for larger tests and used separately for smaller tests (See SyncLink Cluster Concept pages 23 and 24)
• Combining larger and smaller Mainframes where the smaller can be optimized for extreme mobility in specific applications
This together with further details on cooling, number of channels and dimensions of the
5 available Mainframes can be found on pages 8 and 9.
There are 6 VMEbus boards to choose from when populating a Mainframe as follows:
• PQ12 and PQ20 which are combined System Controllers and Power Supplies for
•
MF02 to MF06
VS20 and PPC7D, which when operating together, fulfill the System Controller and
•
•
Power Supply requirements for the MF10 Mainframe
SC42 which provides a signal conditioning engine and infrastructure for any 4
Modules
SL21 allows multiple Mainframes to operate in a Cluster and can be found on pages
21 and 22
These pages introduce 15 Modules to accommodate virtually every signal type. The table on page 15 shows which Module corresponds to which signal type and provides a useful overview. It is important to note that any number or any combination of these
Modules is possible, with the only restriction being the amount of available slots in the chosen Mainframe.
The purpose of the 8 available SubModules and their relationship with their corresponding Module is explained on page 22.
The SyncLink Cluster Concept shows how an SL21 VMEbus board can connect up to
4 Mainframes to form a Cluster. This concept is scalable, since by simply adding an additional SL21 board, 4 Clusters can be linked together, operating as one system.
This is beneficial as Clusters not only offer a limitless channel count but improve cable management, offer greater geographical reach and avoid data bottlenecks.
This page focuses on two of the PAK MKII front end’s accessories, the MiniTerminal and the SeatFrame. The MiniTerminal presents valuable test information presented on a LED display as well as buttons with which Users can input information into the system. The SeatFrame provides the means to fasten both an PAK MKII and a laptop to a car seat for tests involving motor vehicles.

Mainframes are machined from aluminum and accommodate between 2 and 10
VMEbus boards as shown in the tables below.
An unusual concept used by the PAK MKII system is that the Power Supply is contained on a VMEbus board. This enhances the modularity of the system as it can be readily maintained and upgraded. A battery is contained behind the backplane.
All VMEbus boards are cooled by conduction only. This is advantageous as no dirty or dusty air moves within the Mainframe. The external surfaces of the smaller Mainframes
(MF02 to MF04) are cooled through natural convection. The MF06 is cooled through a combination of natural and forced convection while the MF10’s external surfaces are cooled by forced convection only. The fan speed of the MF06 and MF10 is controlled by software to maintain a suitable running temperature. For noise sensitive measurements the fan can be switched off for periods of up to 20 minutes during which time the
Mainframe acts as a large heat sink.
A convenient carrying handle is provided on MF02, MF03, MF04 and MF06 Mainframes.
It can be removed if required.

Description:
The SC42 board provides the isolated power, signal processing and mechanical infrastructure for up to 4 signal conditioning Modules. It is a highly complex board using 5 powerful 24bit DSPs to process large volumes of data transferred between the VMEbus and each Module. It also provides isolated power for each Module, sample timing infrastructure as well as internal communication interfaces used to set parameters for each channel.
A DC accurate calibration engine is available to calibrate each Module using both DC and AC signals. A 0.02% 3ppm/°C accurate internal reference and DAC is used to generate both DC and AC calibration signals which are switched into the front end of each channel. All applicable channel settings such as gain and AC/DC coupling are selected and individually calibrated. Calibration values are written into non-volatile system memory which expire automatically with hardware/firmware changes or after a given time. Auto calibration typically commences at start-up but for greater accuracy, can be requested at anytime such as at specific operating temperatures.
The SC42 also provides the flexibility of easy interchangeability of Modules within the same Mainframe or other Mainframes, enabling Modules to be smaller and less costly. This empowers Users to economically purchase additional Modules to satisfy their measurement and control requirements. Modules are plugged in through the front panel of the SC42 and can be inserted and removed without removing the SC42 board itself.

As VMEbus boards are too large to provide a sufficient variety of signal conditioning amplifiers in a single Mainframe, a sub-VMEbus conceptual tier exists where 4
Modules can be inserted into the front panel of an SC42 VMEbus board. A notable feature is that these Modules can easily be inserted and extracted through the front panel of the SC42 allowing the User complete freedom to configure the measurement system for a particular test. Typically each Module contains 4 channels with some containing 8 channels and others 1 or 2.
Modules are innovatively packaged in an aluminum casing so as to optimize both size and thermal performance. Most Modules are galvanically isolated providing a 50V difference between the ground potential of the Module and that of the Mainframe.
Currently there are 15 Modules to choose from, each optimized for a specific task.
New Modules are continuously under development to accommodate new User requirements such as higher bandwidths or monitoring new communication networks such as FlexRay and EtherCAT.

5 thermocouple based SubModules exist, each containing dedicated thermocouple connectors. The SubModule contains a pair of miniature thermocouple connectors of the appropriate alloy and color according to either IEC or ANSI standards. Coldjunction-compensation is facilitated through the use of a 0.5°C accurate temperature sensor in thermal contact with the connectors’ contacts. The SubModule type is identified through a TEDS interface
Each SubModule connects to the THM42 Module through a 300mm fly-lead ending with a 7 way Lemo FGG 0B connector.
These 5 SubModules can be listed as follows:

SyncLink takes the concept of modularity one step further by providing the means to group up to 4 Mainframes together to form a Cluster, up to 4 Clusters together to form a SuperCluster and so on. In this way a limitless number of Mainframes are grouped together providing a limitless channel count, greater geographic reach, improved cable management and reduced bottlenecks.
The SyncLink Cluster concept operates using a common clock transmitted over a single fibre-optic cable from an SL21 VMEbus board to a PQ12, PQ20 or VS20 contained in slot 1 of each Mainframe. This cable follows the same routing path as the
Ethernet cable used to transfer data to each Mainframe. A fibre-optic cable is used to ensure sub-50ns timing resolution and immunity to outside electrical interference.
In order to simplify the routing of cables, the SL21 board contains a 5 port 1000BaseT
Ethernet switch together with a 4 port fibre-optic SyncLink source and 1 port fibreoptic SyncLink receiver in a single VMEbus board. These ports allow Mainframes to be grouped together in units of 4 to form a Cluster. Only one SL21 board is required per Cluster and can be plugged into anyone of the Mainframes which form that
Cluster.
This concept is scalable, since by simply adding an additional SL21 board, 4 Clusters can be linked together. As such 16 Mainframes will only need 5 SL21 boards. There is no limit to adding more Mainframes as long as the appropriate SL21 boards are added.
See page 22 for diagrams illustrating these concepts.
Where used:
• To synchronize multiple Mainframes in Clusters, SuperClusters and so on
Features:
• 5 port Gigabit Ethernet switch containing:
1 port on the far left which is connected to the Workstation or to another SL21 at a higher level
4 ports to the right which service the 4 Mainframes in the Cluster or another 4
SL21 boards in a SuperCluster
• 5 port SyncLink hub containing:
1 port fibre-optic SyncLink receiver which is the port on the far right and which is left open if there is only one Cluster or in the case of a SuperCluster is connected to another SL21 at a higher level
4 port fibre-optic SyncLink source which provides the SyncLink signal to the 4
Mainframes in the Cluster or to 4 further SL21 boards in a SuperCluster
•
•
1 SL21 board is required per Cluster and can be inserted into any of the 4
Mainframes forming the Cluster. It can also be inserted into its own Mainframe
1 additional SL21 board is required for a SuperCluster of up to 4 Clusters (or up to 16 Mainframes)
•
•
•
•
•
The SL21 VMEbus board uses proven Ethernet concepts of 1000BaseT. The
SyncLink fibre-optic cable and SyncLink hub mimics Ethernet’s CAT5E cable and switch, providing identical routing paths for both cables
Channel count is increased. A 10-slot Mainframe can have 128* channels, a Cluster of 4 Mainframes 496*, a SuperCluster of 16 Mainframes 1968*. There is no Master/
Slave limitation
Clusters and SuperClusters have the benefit of shorter signal cables contributing to lower cabling costs, reduced cable noise, reduced cabling faults and improved cabling management
SyncLink optimizes measurement infrastructure and cost as multiple small systems can be used separately in some applications but also together for larger tests
If a data bottleneck occurs between the Cluster and Workstation then multiple
Workstations can be deployed on the same network
•
•
•
Clusters increase distance between Mainframes to reach remotely placed sensors
Measurements within one Cluster can be spread over a large area with a 1000m radius
Measurements within one SuperCluster can be spread over a large area with a
2000m radius
* Calculated on an average of 4 channels per Module in an MF10 Mainframe

Accessories
The MiniTerminal provides the User with valuable test information, such as instructions to a motor vehicle driver. It contains a super-bright LED display with 2 rows of 24 alphanumeric characters for optimum visibility in daylight conditions. User input is provided through 6 buttons which can be labeled as soft keys. These buttons are easy to operate even whilst driving. A piezoelectric buzzer is contained within the unit.
The RS232F based communication to the PQ12, PQ20 or VS20 (depending on
Mainframe size) is through one of 2 sockets found on both the left and right sides of the MiniTerminal. This affords the User the choice of the most comfortable position to insert the RS232F cable.
The MiniTerminal is compact (115 x 48 x 29mm) and machined from aluminum with a tripod screw thread on its rear lid for easy mounting through third party mounting kits.
