SLOT CONFIGURATION
The CMX09 is a 9-slot PXI Express mainframe with 1 system controller slot, 1 PXIe timing slot,
1 PXIe hybrid slot and 6 PXIe peripheral slots.
The PXI Express hybrid slot delivers connectivity to either an x4 PCI Express link or to the 32-bit,
33 MHz PCI bus on the backplane. This allows PXI Express hybrid-compatible, or 32-bit
cPCI/PXI-1 modules (without J2 connector), to be used in this slot.
The PXIe timing slot accepts either a PXI Express module or a PXI Express system timing
controller for advanced timing and synchronization.
The system controller slot has configurable 4x4, 2x8 and 1x8 links, which allows all PXIe
controllers to be supported per spec.
SPEED, FLEXIBILITY, AND PERFORMANCE
Best in Class Bandwidth
The CMX09 uses a 4-lane 2nd generation PCIe backplane to achieve unmatched data rates of up to
2 GB/s per slot and 8 GB/s system. This is especially useful when using high-speed instruments
like digitizers, oscilloscopes, and signal generators.
14
CMX-09 Features
www.vtiinstruments.com
Advanced PCIe Switch Fabric
The CMX09’s advanced switch fabric uses innovative methods like non-transparent bridging
(NTB) and partitionable switch architecture to allow slot-to-slot direct communication and true
multi-root support.
Slot-to-slot direct communication allows data from any slot to be read directly by another slot
without having to go through the controller and host. This allows extremely high-speed
deterministic data transfers between slots which is very useful for applications that require closed
loop control.
True multi-root support allows any slot to be used as a root-complex meaning data processing or
memory units can be plugged into any slot on the chassis. This combined with slot-to-slot
communication capability allows data to be streamed directly from a plug-in module to a root
complex for storage or processing without burdening the host processor.
PXImc Ready
The slot-to-slot direct communication capability combined with true multi-root support allows the
CMX-09 to be the first and only PXImc (PXI MultiComputing) ready mainframe in the industry.
This provides the ability to use multiple processor modules, in any slots on the mainframe, to
share the processing requirements for an application.
This allows CMX-09 to be used in high-speed, high-channel count, applications where large
amounts of streaming data require in-line processing and analysis.

CMX-09 Features
www.vtiinstruments.com
IEEE-1588 DISTRIBUTION
The CMX-09 backplane contains a built-in mechanism for distributing an IEEE-1588 time source
to the plug-in modules. This mechanism is only supported when using the EMX-2500 Gigabit
Ethernet LXI controller which allows the time stamping of data from all plug-in modules on a
common time-base for advanced timing and synchronization. In addition, it also provides the
capability to synchronize PXI systems with LXI instruments.
SYSTEM MONITORING FOR SIMPLIFIED MAINTENANCE
The CMX-09 has a smart-switch display on the front panel which reports the chassis status/health
and can also be used to control chassis fan speed.
•
•
•
•
Temperature monitoring: The CMX-09 chassis monitors its own internal temperature using
temperature sensors placed within the chassis. The smart switch can display the measured
temperature readings and alert the user if an over-temperature condition occurs.
Power monitoring: The smart switch monitors the power rail voltages and reports fault
conditions if they occur.
IP Address: When used with the EMX-2500 Gigabit Ethernet LXI controller, the smart switch
displays the mainframe IP address allowing quick and easy connectivity to the instrument
Fan Speed: The smart switch allows the user to adjust the mainframe fan speed. When set in
auto-mode, the fan speed is optimized based on the temperature readings from the
temperature sensors.
In addition, a DB-9 connector has been implemented in the rear of the chassis that allows for
voltage monitoring and remote inhibit. Please refer to Remote Voltage Monitoring and Inhibit
Control on page 19 for detailed information.
RUGGED DESIGN
The CMX-09’s rugged, compact, and light-weight design makes it ideal for portable applications.
The CMX-09 is available with optional handles which makes it convenient to lift and move. There
are no ventilation-holes on the bottom and top of the chassis, which protects the instruments from
spills when used in industrial environments.
FIGURE 2-6 - TABLE TOP OPTION
CMX-09 Features
17
VTI Instruments Corp.
For in-vehicle or on-floor applications, a bolt-down option is available which allows the
mainframe to be mounted to a surface. The bolt-down option includes vibration isolators that can
withstand up to 11 G’s of acceleration on the vertical axis and 4 G’s of acceleration on the
horizontal axis. In addition, the clearance between the surface and mainframe is adjustable to
accommodate user constraints.
FIGURE 2-7 - BOLT DOWN OPTION
Traditional rack-mount options are also available.
FIGURE 2-8 - RACK MOUNT OPTION
FIGURE 2-9 - RACK MOUNT OPTION WITH DOOR
EXTERNAL CLOCK
The CMX-09 includes a pair of IN/OUT BNC connectors in the rear to allow for an external
10 MHz reference clock. When a 10 MHz clock signal is detected on the IN connector, the
internal clock is phase locked to the external clock. This reference clock may also be driven by a
system timing module in slot 5. System timing controllers are high-stability clock sources which
18
CMX-09 Features
www.vtiinstruments.com
provide the ability to drive the PXI star and PXI Express differential star triggers. In addition,
timing controllers typically have the ability to import and export the PXI trigger lines on the
backplane.
The OUT BNC connector provides a buffered, non-TTL version of the 10 MHz reference clock.
REMOTE VOLTAGE MONITORING AND INHIBIT CONTROL
The CMX-09 features remote voltage monitoring and inhibit control through a DB-9 connector
located on the rear of the chassis. The DB-9 connector is intended for voltage monitoring as well
as using the inhibit functionality of the chassis. The DB-9 connector should not be used to provide
power to external devices.
In order to use the remote inhibit functionality, remote inhibit must first be turned on which can be
done through the front panel switch. While remote inhibit is ON the chassis will not shut down
through the front panel switch. Once remote inhibit is ON the chassis can only be shut down by
connecting the remote inhibit pin (pin 5) to a ground pin (pin 1 or 9).
The following table outlines the pin assignment of the DB-9 connector.

Do not short the DB-9 connector probe leads together. Doing so can cause permanent
damage to the chassis.
INNOVATIVE COOLING TECHNIQUES
The innovative cooling techniques implemented on the CMX-09 allow it to be a “True 4U
chassis”. Traditional PXIe chassis, even if advertised as 4U, often require an additional 1U rack
space for airflow. The CMX-09 uses innovative cooling methods to pull cool air from the front
and sides of the chassis, rather than the top, and expels it from the rear. The temperature control
mechanism monitors the temperature at the exhaust and automatically adjusts fan speed to
optimize the internal temperature of the chassis.
The cooling implementation allows an extended temperature range of up to 70°C 1.
SERVICEABILITY
The CMX-09 was designed with serviceability in mind. The CMX-09 sports a very modular
design with an easily removable power supply, fan assembly, and filter tray. The mentioned
components were designed to be easily removed from the chassis to simplify on-site diagnostics
and the replacement of any failed components.

SECTION 3
PREPARATION FOR USE
SYSTEM POWER REQUIREMENTS
The CMX-09 operates from 90 V to 264 V AC at 43 Hz to 63 Hz. A power source providing at
least 920 VA is required in order for the chassis to function correctly.
CONNECTING THE MAINFRAME TO EARTH GROUND
The supplied power cord grounding conductor provides adequate grounding for this voltage and
frequency level. However, if an ungrounded power cord is to be used or if the power source is not
grounded please use the following steps to connect the chassis to a safety ground.
1) Connect a 16 AWG (or larger) wire to the ground terminal located on the rear panel (this
connection is marked by a symbol). Use a grounding lug with a star washer or a toothed lug,
to make this connection.
2) Attach the other end of the wire to a permanent earth ground also using a star washer or a
toothed lug.
Chassis Ground Terminal
FIGURE 3-1 - CHASSIS GROUND TERMINAL
AIR FLOW REQUIREMENTS
The CMX-09 is designed to intake air from the sides and front of the unit. The fans pull air into
the unit from the sides and front ventilation ports of the unit and push it out of the rear.
There are no ventilation ports on the top or bottom of the chassis to prevent spills from entering
and damaging the chassis.
CMX-09 Preparation for Use
25
VTI Instruments Corp.
Placing objects against the ventilation ports on either side of the chassis or against the rear of the
unit will obstruct airflow and cause the chassis to overheat. Prolonged obstruction of ventilation
can cause permanent damage to the chassis. Therefore, consideration should be given when
placing objects around the chassis so that the airflow is not obstructed.
If the internal temperature of the chassis exceeds 90 °C for more than 15 minutes the chassis will
immediately shut down. Similarly, if the internal temperature reaches 100 °C the chassis will also
immediately shut down.
FRONT PANEL SMART SWITCH OPERATION
Please reference the Using the Front Panel section on page 29 for instructions on how to operate
the integrated user interface.
TURNING ON THE CHASSIS
The chassis will not power on until a controller has been installed. A VTI controller (such as the
EMX-2500) or similar controller must first be installed.
Turning on the Chassis
1) Ensure the power switch at the rear of the chassis is in the OFF position.
2) Connect the AC power cord.
CAUTION
Do not turn on the chassis before inserting the controller into the chassis.
3) Insert the controller into slot 1 (left-most slot; a triangle with a 1 inside of it is located above
the slot). Take care that the card is properly mounted on the red brackets and that the ejector
handle is fully engaged. When installed properly, the controller should not be able to be
removed except by pressing down on the ejector handle. Please reference the Plug-in Module
Installation and Removal section on page 26 if you have difficulty installing the controller;
the installation process is the same as installing a plug-in module.
4) Attach the controller to the chassis with the Philip’s screw located at the very top of the
controller.
5) Turn the power switch at the rear of the chassis to the ON position.
6) Finally, to turn on the chassis, press and hold the center toggle button on the front panel for
1.5 seconds.

software to adjust the fan speed to the appropriate
setting.
Fans are running on the LOW
setting even when the temperature
of the chassis is exceeding the
maximum temperature
A previous user could have set the fan setting to
LOW. The chassis is programmed to remember the
most recent settings, meaning that even upon a reboot
of the chassis the chassis will continue to operate with
the most recent settings. Navigating to the ‘Fan
Setting Screen’ and selecting AUTO will allow the
software to adjust the fan speed to the appropriate
setting.
The chassis will not shutdown

TEMPERATURE DETECT
If the system is exceeding the maximum programmed temperature (default maximum temperature
is 90°C) then the temperature on the ‘Temperature’ on the ‘Main Status Screen’ will read: ‘FAIL’.
The ‘Temperature Screen’ will have exclamation marks following the temperatures which are
exceeding the maximum temperature with their respective sensor. The chassis is allowed to exceed
the maximum temperature of 90°C for 15 minutes after which it will immediately shut down. If
the chassis reaches 100°C at any point, the chassis will immediately shut down.
HANDLING THE CHASSIS AND CABLES
The CMX-09 features two robust handles in order to be as portable as possible. The handles are
designed to support the full weight of the chassis and it is strongly recommended that both handles
are used during transportation.
All cables must be handled with care. The power supply cables run tightly against the frame of the
chassis when routed to the backplane; therefore the user must exercise extra care when inserting
the power supply into the chassis to prevent pinching or tearing of the cables. Caution must also
be exercised when removing the fans or power supply from the chassis since they are connected to
the backplane. Forcing the fans or power supply out of the chassis without disconnecting their
respective wires can seriously damage the backplane and/or destroy the wiring.
