Description
Front Panel
The left side of the WBK25 front panel will include a MAC (Media Access Control) Address Label.
The label displays the device serial number in both barcode and base 10 formats. The label also
provides the Ethernet address (MAC Address) which is derived from the serial number in hexadecimal.
If prompted to enter a serial number in software, use the base 10 number. After doing so, conversion to
a hexadecimal number for use in addressing will be automatic.
Note: If your network administrator asks you for a MAC number or a MAC Address, provide him [or
her] with the hexadecimal number that is located at the bottom of the label.
Rear Panel
The WBK25 rear panel includes a power switch, DIN5 power in connector, Ethernet port, 5 LEDs
(2 of which are on the Ethernet port), and three parallel ports. These items are described below, in order
as they appear from left to right.
WBK25, Rear Panel
POWER Switch: A rocker-type switch with a “0” label for Power Off, and a “1” for Power On.
DIN5 POWER IN: +10 to +30 VDC, through a socket type DIN5 connector on the chassis. Power is
typically supplied from a TR-40U power adapter.
ETHERNET: The 10/100BaseT Ethernet port can connect to the Ethernet port of the host PC, or to an
Ethernet network. Either of two Ethernet patch cables may be used to make the connection. CA-242 is
a
1.5-foot long cable. CA-242-7 is a 7-foot long cable. Note that the Ethernet connector has two built in
LEDs (Tx and Rx) that indicate traffic flow. These are discussed with the three other Ethernet-related
LEDs.
To be CE compliant, the length of the Ethernet cable can not exceed 10m.
LEDs:There are 5 ETHERNET Status LEDS. Two rectangular LEDs (Tx and
Rx) are built into the frame of the Ethernet port. The other three LEDs,
located just to the right of the Ethernet port, are round and are labeled
L, T, and D for Link, BaseT, and Duplex, respectively.
Tx – “ON” indicates traffic is being transmitted (see following figure).
Rx – “ON” indicates that the port is receiving traffic.
L (Link) “ON” indicates a link exists. “OFF” indicates no link.
T(BaseT) “ON” indicates 100BaseTx; “OFF” indicates 10BaseT.
D (Duplex) “ON” indicates full duplex, which allows simultaneous
two-way data traffic. “OFF” indicates half-duplex, which
only allows one-way data traffic at any given time.
Tx and Rx LEDs
EXPANSION PORTS 1, 2, and 3:The three parallel ports are used to expand the system with up to
three additional devices. Each of these ports can be connected to the parallel port of a WaveBook/512A,
/516, /516A, DaqBook/2000A, DaqBook/2000X, WBK40, or a WBK41 via a CA-35-2 (2-foot) or a
CA-35-12 (1-foot) cable.
WBK25, pg. 2 919896 WBK25 Ethernet Interface Module User’s Guide

Operational Aspects
The WBK25 provides an interface for high-speed Ethernet connectivity. The module contains one 10/100BaseT
Ethernet port for connection to a PC’s Ethernet jack or to an Ethernet network hub. The WBK25 also includes three
parallel ports, which are designated as “expansion ports.” Each port can be attached to a to one device, such as a:
WaveBook/512A, /516, /516A, DaqBook/2000A, DaqBook/2000X, WBK40, or a WBK41.
WBK25’s three parallel ports are labeled as expansion ports 1 through 3. They are used to
connect to WaveBook, DaqBook, WBK40, and WBK41 systems via parallel cables. The ports
cannot be used for other parallel devices, such as printers and scanners.
Data transfer rates with the WBK25 depend on the network to which it is attached. If the WBK25 is used in a
point-to-point configuration, where the WBK25 and the PC are the only devices on the network, then data transfers
that exceed 2 Mbytes per second can be expected. The point-to-point scenario is recommended for WaveBook
applications where data transfer speeds may be critical.
A single WaveBook, attached to a WBK25, can operate at its maximum 1 Msamples/s sampling rate while
transferring data continuously to the PC. If the application requires that more than one WaveBook be attached to
one WBK25, with each operating at its maximum 1 Mreading/s sampling rate, contact the factory for the latest
information on data transfer rates. We will continue to improve the WBK25’s data transfer rates as PCs and
networks themselves increase in speed. Users will be able to perform the upgrades in the field.
If the WBK25 is used with DaqBook/2000A, DaqBook/2000X, and/or WBK40 series options, then up to three of
these devices can be attached to one WBK25 and will be capable of simultaneously transferring data at their
maximum sampling rate.
If the WBK25 is attached to a shared Ethernet network the data transfer rates will be dependent on the network
traffic at the time. It is not possible to guarantee maximum data transfer rates in this mode. However, the
WaveBook offers internal memory option cards (WBK30 series) for applications such as this, so that the acquired
data can be locally stored in the event that the shared network traffic prohibits the WaveBook from transferring data
at the same rate at which it was acquired.
Note: It is possible to attach multiple WBK25 units to a single PC that has more than one Ethernet port. It is also
possible to attach several WBK25 units to a multi-port Ethernet hub. Performance under these conditions
will be dependent on the PC’s ability to handle multiple networks.

Connecting a WBK25 to the Ethernet
Connecting a WBK25 to the Ethernet
Introduction
The WBK25 connects 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.
CAUTION
Turn off power to the system devices and externally connected equipment before
connecting cables. Electric shock or damage to equipment can result even under low-
voltage conditions.
Take ESD precautions (packaging, proper handling, grounded wrist strap, etc.)
Reference Note: Adobe PDF versions of user
manuals will automatically install onto your
hard drive as a part of product support. The
default location is in the Programs group,
which can be accessed from the Windows
Desktop. You can also access documents
directly from the data acquisition CD via the
<View PDFs> button located on the CD’s
opening screen.
Minimum System Requirements

Windows Operating System
RAM, as follows:
32 Mbytes of RAM for Windows NT
64 Mbytes of RAM for Windows 2000
64 Mbytes of RAM for Windows XP
Contact the factory or your service representative in regard to Ethernet connectivity if
your operating system is other than Windows NT, Windows 2000, or Windows XP.
WBK25, pg. 4 919896 WBK25 Ethernet Interface Module User’s Guide

STEP 1 – Install the Software
1. Remove previous version Daq drivers, if present. You can do this through Microsoft’s Add/Remove
Programs feature.
2. Place the Data Acquisition CD into the CD-ROM drive. Wait for PC to auto-run the CD. This may take a
few moments, depending on your PC. If the CD does not auto-run, use the Desktop’s Start/Run/Browse
feature to locate and run the CD’s setup.exe file.
3. After the intro-screen appears, follow the screen prompts.
STEP 2 – Determine the type of Network Connection
To properly connect a WBK25 you must determine the type of network that it will become part of. This is
because the type of network used has a direct bearing on the IP address that will be assigned.
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 with no DHCP Server
(Local Area Network with no Dynamic Host Configuration Protocol)
Dedicated Network - with a direct cable connection from the PC to the device
In this scenario the WBK25 is connected directly to an Ethernet jack on a host computer.
Dedicated Network using a Direct Cable Connection
Dedicated Network - making use of a network hub or switch
In this scenario the WBK25 is connected 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
WBK25 Ethernet Interface Module User’s Guide 919896 WBK25, pg. 5

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 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)
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, one
or more WBK25 modules are connected to the network hub/switch.
LAN with a DHCP Server
Notes:
Using the WBK25 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.
➣
➣ Contact your network administrator before connecting a WBK25 to a corporate network.
LAN with no DHCP Server
(Local Area Network with no Dynamic Host Configuration Protocol)
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.

Install the Ferrite Inductive Collars
1. Place one ferrite collar at each end of the Ethernet cable.
Snap the two collars shut. See photos.
2. Place the remaining ferrite collar next to the DIN5 connector on the
power cable. Snap the collar shut.
3.
Use a tie-wrap (one per ferrite collar) to secure each collar to its
respective cable.
This partial view of the host PC shows the
Ethernet cable with a ferrite collar. The
PC’s connection to the ground-line is also
visible.
Tie-wrap goes through
this opening.
4. (Optional) Trim the excess tie-wrap material. While trimming
use care to avoid cutting into the cables.
This completes the installation.
This partial view of the data acquisition
device shows its connection to the ground-
line. It also shows two ferrite collars, the
foremost of which is clamped to the power
cable. The background collar is clamped
onto the Ethernet cable.
