IOtech 640 and 650 Series Panels

IOtech 640 and 650 Series devices are dynamic signal analyzers used for monitoring and analyzing
machinery and structures in regard to sound, vibration, and rotation. The device hardware is the signal
conditioning and acquisition engine, while the software defines the specific analysis and monitoring
features of the system. Since the software [in the host PC] determines which capabilities will be used, it is
easy to upgrade the system and add more capabilities over time.

There are currently 4 models in the 640 and 650 product line. These are 640e, 640u, 650e, and 650u,
where
“e” indicates Ethernet Interface and “u” indicates USB2.0 Interface. The following matrix compares

IOtech 640 & 650 Series 878893 What are IOtech 640 & 650 Series Devices? 1-1

The IOtech 640e and 650e include a high-speed Ethernet engine powered by a PowerPC processor. The
640u and 650u include a high-speed USB2.0 engine. These Ethernet and USB interfaces allow all
acquired data to be transferred to the PC in real time at 630k samples/sec. This means that every acquired
data point can reside on the host PC’s hard drive, making re-creation and post acquisition analysis of
acquired data as precise as possible. Many other analyzers simply store frequency-domain information,
which results in play-back that is less precise than the original real-time measurement. In comparison, the
640 and 650 models transmit all time-domain measurements. This means there is no data loss when
analyzing acquired waveforms. Since the data is already on the host PC’s hard drive there is no time lost
transferring data.

Another advantage of the 640/650 architecture is that there is virtually no limit to the length of time
continuous data can be acquired. Many other systems do not offer continuous time-domain transfer to the
PC, and as a result the waveform length is limited by the amount of built-in data storage. In regard to
640/650 units, the only limitation is the amount of available hard disk memory on the host PC, or that
which can be accessed by a PC on a network.

• Features of the Dynamic Signal Inputs

o a current source for transducer biasing (ICP)

o detection of a transducer fault

o AC coupling: 0.1 Hz for IOtech 650 models; 1.0 Hz for IOtech 640 models; or DC coupling

o ±10 V range (IOtech 640 models)

o ±40 V range (IOtech 650 models)

o anti-aliasing filters: 3-pole low pass filter in hardware; set appropriately for each analysis rate

o pseudo-differential inputs

o support for TEDS (Transducer Electronic Data Sheet) in eZ-Analyst

o any analog input channel can serve as a tach input

o channel-to-channel phase matching

• For 640u and 650u - Easy Connection to USB2.0-ready Notebooks, Desktop PCs, or USB2.0 Hubs.

Note that the USB2.0 port allows a continuous stream of data to be collected and stored in the host PC.

• For 640e and 650e - Easy Connection to Ethernet-ready Notebooks, Desktop PCs, or Ethernet Hubs.

Note that the 10/100BaseT Ethernet port allows a continuous stream of data to be collected and stored
in the host PC.

• Analog Input Channels: BNC connectors.

• 8 Digital I/O Channels: DB9 connector for connection of Digital I/O signal lines.

Note: eZ-NDT or eZ-TOMAS software must be used to make use of the Digital I/O.

• Analog Channel Triggering

• Pre- and Post-Trigger Readings

IOtech 640/650 Series 878893 Block Diagram 2-1

General Comments

Ethernet Connection (640e and 650e models only)

IOtech 640e and 650e units transfer the acquired data to the PC via a 10/100BaseT Ethernet connection.
The Ethernet connection allows for a continuous stream of data to be collected and stored.

The 10/100BaseT Ethernet interface can be used in a point-to-point application, such as when attached to a
notebook PC and used in the field. In this case the 16 Mbytes of buffer storage built into the unit is
adequate to ensure that continuous data transfers to the PC can occur without risk of data loss.

The 10/100BaseT Ethernet interface can also be used to connect the unit to a network, presuming the
network has enough available bandwidth. The network bandwidth required is a function of the number of
signals being measured, and the bandwidth of the signals.

USB Connection (640u and 650u models only)

IOtech 640u and 650u units transfer the acquired data to the PC via a USB2.0 connection. When a
computer has a board with USB 2.0 ports, an “Enhanced” USB controller can be found in the Device
Manager. The Device Manager will also show two other USB controllers. This is due to the fact that
USB2.0 circuitry includes 3 chips [one for the actual USB2.0 capable devices and two for backward
USB1.1 compatibility]. Thus a USB 2.0 motherboard can host any USB device (version 2.0 or lower),
assuming there are no defects with the board, system, and/or device.

USB Notes:

o IOtech 640u and IOtech 650u require connection to USB2.0

o USB 1.1 (obsolete) hubs will work on USB 2.0 ports, but cannot utilize USB 2.0 capabilities.

o Hi-Speed and Full/Low-Speed USB devices can coexist on USB 2.0 hubs.

o USB 2.0 hubs can be used on computers with USB 1.1 ports, but will not exhibit USB 2.0

capabilities.

o Minimize hub use and keep USB cables as short as possible.

o Regardless of the USB hub or port used, if power to the 640u or 650u device is insufficient,

connect a TR-2U power adapter to the unit’s External Power jack.

Power

640e and 650e units can be powered directly from a 6 to 16 VDC source. They can also be powered from
a 100 to 250 VAC source via its power adapter, which converts the AC to the required DC.

640u and 650u units can be powered solely from a USB2.0 bus, or optionally from a 6 to 16 VDC source
via the external power connector.

LEDs 640 and 650 Series modules have 2 LEDs on the front panel. The LEDs function as follows:

Power LED: The “Power” LED blinks during device detection and initialization; then remains on solid

as long as the module has power. If there is insufficient power the LED will go off.

Active LED: This LED is on whenever active communication is taking place between the 640/650 and

the host PC. Note that the Active LED will be on solid during a data acquisition.

2-2 Block Diagram 878893IOtech 640/650 Series

Digital I/O

To make use of the Digital I/O feature the 640 or 650 must be operating with eZ-TOMAS or eZ-NDT.
The 8-bits of digital I/O are provided via a rear panel DB9 connector. Each bit is programmable as
input or output.

Signal Conditioning

Every input to a 640 or 650 system is software programmable for AC/DC coupling, IEPE source [if AC
coupling is selected], and is capable of reading sensor calibration information using Transducer Electronic
Data Sheets (TEDS). eZ-Analyst software is required if the TEDS functionality is to be used.

When IEPE sensors are attached, AC coupling with bias current is selected via software. AC coupling
without bias is also possible for measuring any AC waveform. DC coupling, which is useful for proximity
sensor applications, can also be selected via the software.

For IEPE sensors, indication of an open or shorted fault is available within the eZ-Analyst software
application.

Source Output (640 units only)

640e and 640u each include one analog output channel capable of generating continuous waveforms.
These waveforms are programmable in regard to amplitude and frequency per product specifications.

They can be continuous sine, random, burst, or arbitrary.

The 640 and 650 Front Panels include the following connectors and LED indicators.

ANALOG COMMON

ANALOG SIGNAL INPUT CHANNELS

models have 4 input channels. The 650 models have 5 input channels.

The BNC center-conductor is the signal HI and the BNC shell is the signal LO. Each BNC shell is
connected to the chassis ground through its own channel-dedicated 1 kΩ resistor. Consequently, the shell
is not meant to be driven with respect to earth ground more than ±10V.

An additional consideration pertains to input transducer setup. If the transducer case is effectively earth
grounded through its connection to a device under test, there exists the possibility for added measurement
noise due to the ground loop that is created. The pseudo-differential input rejects much of this noise.
Electrically isolating the transducer from the test device minimizes noise.

OUTPUT (640 units only)

discrete amplitudes (see specifications). The output waveform parameters are controlled by software and
can be sine, swept-sine, random, burst, or arbitrary. The output can be used as a test source for the input
channels or as excitation for other system elements, such as the amplifier for a shaker table. Detailed
information on the excitation source and its operation can be found in the applicable eZ software

documentation, e.g., the eZ-Analyst User’s Manual.

Status LEDs 640 and 650 Series modules have 2 LEDs on the front panel. The LEDs function as

follows:

Power LED: The “Power” LED blinks during device detection and initialization; then remains on solid as

long as the module has power. If there is insufficient power the LED will go off.

Active LED: This LED is on whenever active communication is taking place between the 640 or 650 and the

host PC. Note that the Active LED will be on solid during a data acquisition.

Ethernet Connection and System Power-up

As this document goes to print, Ethernet connectivity can only be used with
Windows 2000 or Windows XP operating systems.

Overview

640e or 650e, Rear Panel

IOtech 640e and 650e connect directly to an Ethernet port on a PC or network hub, via the unit’s built-in
10/100BaseT Ethernet interface. An Ethernet patch cable CA-242 (1.5 foot) or CA-242-7 (7 foot) cable is
used to make the connection. Note that either a straight-through or a cross-over cable may be used. The
circuitry automatically adjusts for the cable type to ensure proper connection.

Contact the factory or your service representative in regard to Ethernet connectivity if
your operating system is other than Windows 2000 or Windows XP.

STEP 1 – Install the Software

Install the software prior to connecting the 640e or 650e to the Ethernet. If you have not already installed the software,
do so at this time. Refer to the section entitled Software Installation, page 4-2.

STEP 2 – Determine the type of Network Connection

To properly connect and configure a 640e or 650e, you must determine the type of network that the device
will become part of. This is because the type of network used has a direct bearing on the IP address of the
device.

Briefly, the four network types are as follows:

• Dedicated Network - with a direct cable connection from the PC to the device

• Dedicated Network - making use of a network hub or switch

• LAN with a DHCP server

(Local Area Network with a Dynamic Host Configuration Protocol)

• LAN without a DHCP server

(Local Area Network with no Dynamic Host Configuration Protocol)

Brief descriptions and illustrations follow.

Dedicated Network - with a direct cable connection from the PC to the device

In this scenario a 640e or 650e is connected directly to an Ethernet port on a host computer.

Dedicated Network using a Direct Cable Connection

4-4 Configuring Ethernet Models 640e & 650e 878893 640 & 650 Series

Dedicated Network - making use of a network hub or switch

In this scenario the 640e or 650e connects to the Ethernet through a network hub or switch. At least one
computer is also connected to the hub.

Dedicated Network using a Hub/Switch

Some network devices such as a wireless access point may act as a DHCP server. If this is
the case, follow the instructions for the LAN with a DHCP server. For detailed
information consult the documentation that is specific to your network device.

LAN with a DHCP Server (Local Area Network with a Dynamic Host Configuration Protocol server)

Many corporations use the LAN/Server with DHCP arrangement for their networks. In this type of setup
several computers are typically connected to a network that makes use of a DHCP server. In addition, a
640e or 650e is connected to the network hub/switch.

LAN with a DHCP Server

Notes:

¾ Using a 640e or 650e on a typical LAN may affect the speed of the network and internet data

transfer. Because of this we recommend adding a network card to the computer and using one of
the two dedicated network configurations.

¾ Contact your network administrator before connecting a 640e or a 650e to a corporate network.

640 & 650 Series 878893 Configuring Ethernet Models 640e & 650e 4-5

LAN with no DHCP Server

(Local Area Network with no Dynamic Host Configuration Protocol server)

This scenario looks the same as that shown in the previous illustration, except there is no Dynamic Host
Configuration Protocol (DHCP). In this type of setup, one or more computers are connected to a network;
and each computer has a static IP address.

STEP 3 – Connect the System Components

What you will need to connect a 640e or a 650e to the Ethernet

• An available connection to the Ethernet. The connection can be either

- an Ethernet jack on a computer or

- an Ethernet jack on a hub that is connected to the Ethernet.

• An Ethernet patch cable, e.g., a CA-242 (1.5 foot cable) or a CA-242-7 (7-foot cable).

1. Connect the Ethernet cable to the Ethernet jack on the 640e or the 650e.

2. Connect the other end of the Ethernet cable to the Ethernet jack on the host computer or

network hub.

:

STEP 4 – Power-up the System Components

What you will need

A power supply with a range of 6 to 16 VDC. We recommend the TR-2U power supply.

How to make the connection:

1. Connect the power supply cable, e.g., from the TR-2U, to the External Power connector on the

rear panel of the 640e or 650e.

2. Connect the power supply’s plug to a standard AC outlet.

3. If you are using a power supply with a power switch, position it to “ON.”

4. The 640e or 650e Power LED will light up.
