Titan CPX Expander - Introduction
The Titan CPX Expander allows you to connect up to three Titan CPUs to
configure large channel-count test systems of up to 384 analog channels, plus
digital channels.
Device connecons to the Titan CPX Expander are made using industry-
standard Ethernet cables, which provide communicaon and synchronizaon
on a single cable. Data can be recorded directly to an SD memory card or to a
host PC, and network operaon is possible via TCP/IP or UDP.
This manual is intended to provide the user with an overview of the Titan
CPX Expander, with complete features, specificaons, set up procedures and
operaon. It contains important safety informaon as well.
Support for this product is available by contacng the factory during regular
business hours (9am – 6pm EST) at 301-470-3278. Addional informaon can
be found on our web site: hp://www.marslabs.com

Titan CPX Expander - Operation
ElectrostaƟc Discharge
Electrostac Discharge (ESD) occurs when a stac charge builds up on either
yourself or the Titan hardware, and then you touch the Titan hardware,
which rapidly dissipates the status charge. The spark of the discharge can be
so small that you don’t feel it, however, it can flaw a semiconductor. These
flaws may generate an immediate failure, or, in most cases, cause a slight
reducon in performance which will connue to degrade, eventually leading
to failure of the hardware. When you feel a stac shock, you are experiencing
a minimum of 3,000 volts of electricity.
Even though the input connectors have protecon to prevent ESD damage,
it is good pracce to always ground yourself and the Titan hardware while
connecng and removing sensors.
Always use approved ESD handling procedures to prevent ESD damage.
Grounding Titans
In general, grounding the Titan hardware to the test vehicle or test structure
will usually reduce noise pickup.
All of the analog inputs of the Titan hardware have a return path to ground.
However, it is very important that each sensor have only one return path to
avoid ground loops. When tesng a vehicle, oen the vehicle chassis and
Titan can have very large ground imbalances of one or two volts. In such
situaons, ground the sensors to Titan and use differenal inputs across
the sensor. A totally floang input (like a 9-Volt baery) must have one side
grounded at the point where used, either grounded to Titan or connected to
the vehicle chassis ground via a resistor (e.g. 10K ohm).
If there is a possibility that a floang sensor may be occasionally grounded,
install a 10K ohm resistor from the minus input to Titan ground. When the
sensor is floang, the 10K ohm resistance will reference it to Titan ground,
and when it is grounded, the resistor will allow the direct minus input wire to
reference the remote chassis ground.
Specific Warnings
When using a power adapter with the Titan, always connect the adapter to
the Titan before applying power. Never hot plug a Titan device under any
circumstances - hot plugging may damage the device!
General Guidelines and Warnings

Titan CPX Expander - Operation
Guidelines for Wiring Sensors
Observe the following guidelines when wiring and connecng sensors to the
Titan hardware:
1. Observe polarity of sensor wires
2. Strain relieve all connecons
3. Secure cables with wire es and bundle cables where possible
4. Secure connectors by fastening to the Titan chassis
5. For Thermocouples, apply heat shrink to exposed wires
6. Double check all connecons prior to connecng the cables to
the Titan
7. Use only heavy gauge straight-through CAT-6 Ethernet cables
with locking tabs when connecng Titan CPUs to the CPX
Expander.
8. When roung cables, be aware of sharp edges and pinch points
where cables can bind or be cut, introducing shorts in the wiring

Operation
Front Panel
The Titan CPX Expander front panel incorporates an Ethernet port, Mini-USB
port, five RJ45 connecon ports, status indicators, and a power switch
Status Indicators
P – A green LED indicang that the CPX Expander is ON.
E – A red LED indicang an error condion when lit.
S – A green LED indicang that the device is scanning when lit
R – A red LED indicang that the device is recording when lit.
An unlabeled indicator on the upper leof the CPX Expander indicates
Ethernet hub power and is illuminated when power is applied.
Ethernet An RJ-45 port that provides an Ethernet Local Area Network (LAN) connecon
to the Expander microprocessor.
PGM
A Mini-USB port that provides communicaon with the Expander
microprocessor via a terminal emulator program.
RJ45 Connection Ports
Five RJ45 ports provide connecons for the Expander, the Ethernet LAN, and
up to three Titan CPUs.

Rear Panel
The Titan CPX Expander rear panel has a 4-pin power connector that accepts a
standard Titan Power Adapter (Mars Labs PS12V3A-SM or equivalent).
WARNING: When using a power adapter with any Titan device, always
connect the adapter before applying power. Never hot plug a device under any
circumstances - hot plugging may damage the device!
The CPX Expander power connector accepts
power from a standard Titan Power Adapter.
Should you need to power the Titan CPX
Expander using your own source, connect
using the power connecons shown.
Power Connector
NOTES:
1. The Expander does not provide power to Titan CPU devices. Titan CPU
devices require their own power.
2. The mating connector for 4-pin Auxiliary Power input is available from the
following sources:

Functional Diagram
The diagram below depicts a 256 channel data acquision system using two
Titan CPUs and sixteen Titan Input Modules (a combinaon of Pods and Mini-
Recorders). A common clock establishes and maintains synchronicity between
the CPUs (see note 2 below). The Titan CPX Expander acts as a command and
control hub, direcng commands between the control soware (TCS) and
the appropriate CPU, and relaying responses back. While running, the data
received from the CPUs is stched together and passed upstream.
NOTES:
1. The CPX Expander automatically selects the CPU that provides the Master Clock
by choosing the CPU with the lowest numerical IP address.
2. The clock connection is made using an 1/8” Tip-Ring-Sleeve (TRS) cable between
the SYNC jacks on the CPUs. Note that when three CPUs are used, the clock
signal from the master clock must be split and connected to the remaining two
CPUs.

Titan CPX Expander - Interface
Configuration
The Titan CPX Expander can be operated directly from a host PC or over a
network connecon (see ‘Connecons’ secon).
For operaon using either method, make the connecons to the CPX
Expander as shown:
1. With power removed from all devices to be connected, use a short length of
Ethernet cable (shown in black) to connect the CPX Expander’s ‘Ethernet’ port
to Port 1.
2. Connect the LAN cable (shown in red) to Port 2.
3. Connect up to three Titan CPUs to Ports 3-5 (shown in blue).
4. Make the SYNC clock connecons between the CPUs (illustrated in the
funconal diagram on page 9).
5. Make all sensor connecons to the connected Titan Input Modules before
connuing.
