The WBK25 is an Ethernet-to-parallel port interface, which provides high-speed Ethernet connectivity for
WaveBook, DaqBook, WBK40, and WBK41 systems. Connection to the Ethernet is made via an Ethernet
patch cable, which links the WBK25’s 10/100BaseT Ethernet port to a PC’s Ethernet jack or an Ethernet
network hub.
The WBK25 includes three parallel ports, labeled as expansion ports 1 through 3. Each of these parallel
ports can be attached to one of the designated acquisition devices via a parallel cable. The ports cannot be
used for auxiliary devices such as printers and scanners.

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 and Rx LEDs
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.
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.

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 lowvoltage conditions.
Take ESD precautions (packaging, proper handling, grounded wrist strap, etc.)

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:
previous version Daq drivers, if present. You can do this through Microsoft’s Add/Remove
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

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.

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.
