DaqBoard/3000USB Series – Board Dimensions
In general, all standoffs should be used to mount the board to a metal frame.
Note 1: The standoff at this location connects to the USB chassis for shunting electrostatic discharge.
Note 2: The standoff at this location connects to the DaqBoard/3000USB board’s internal chassis plane for shunting
electrostatic discharge.
WARNING !
Avoid redundant connections. Ensure there is no signal conflict between SCSI pins
and the associated header pin (J5. J6. J7. and J8). Also ensure there is no conflict
between TB7 (thermocouple connections) and the SCSI and/or the 40-pin headers.
Failure to do so could possibly cause equipment damage and/or personal injury.

IG-6 968492 DaqBoard/3000USB Series Installation Guide
WARNING !
Turn off power to all devices connected to the system before making connections.
Electrical shock or damage to equipment can result even under low-voltage conditions.
Scenario 1: Using CA-248 Cables to obtain DB37 Connectors
In this setup a CA-248 cable is connected to each of the 40-pin headers (J5, J6, J7, and J8). The result is
four male DB37 connectors which, as can be seen from the pinouts, offer the same signal connectivity as
the SCSI connector. Note that the J6 header is dedicated entirely to analog expansion and therefore is not
applicable to /3001USB or /3005USB. As in all scenarios, a CA-179-x USB cable is used to connect the
/3000USB Series board to a USB port on the host PC. USB2.0 is recommended.
If you need to find the name of your device, for example, if you are writing a custom program for multiple
devices, navigate from the Windows Desktop to the Device Manager. The navigation path is:
StartÖSettingsÖControl PanelÖSystemÖHardware(Tab) ÖDevice ManagerÖDaqx PnP Devices
You will see the device listed in the format of DaqBoard/3000USB (see first figure, below).
You can change the name of the device by doing a right-click on the device name to open its properties
dialog box, then clicking on the Properties tab (see second figure). You can then change the
“FriendlyName” of the device.

DaqBoard/3000USB Series Installation Guide 968492 IG-7
Scenario 2: Using a TB-100
In this setup a TB-100 screw-terminal board option is connected to the 68-pin SCSI connector via a
CA-G56 shielded cable. However, the use of other cables is possible as noted below. In this example we
can also see that 4 thermocouples are connected at TB7 (on the /3000USB board). This means that 8
analog channels [to obtain 4 differential TC channels] are required (see following figure). Redundant
connections must be avoided. A CA-179-x USB cable is used to connect the /3000USB Series board to
a USB port on the host PC. USB2.0 is recommended.
WARNING !
Before connecting TC wires, ensure that the
associated analog channels are not in use. Failure
to do so could possibly cause equipment damage
and/or personal injury.
The TB7 terminal block can be used to connect up to 4
thermocouples. The first TC channel makes use of Analog
Channel 0 for its positive (+) lead and Analog Channel 8 for its
negative (-) lead. The second TC channel uses analog Channels 1
and 9, and so on, as indicated in the pinout to the left.
In DaqBoard/3000USB Series applications, thermocouples should only be
connected in differential mode. Connecting thermocouples in single-ended mode
can cause noise and false readings. Appendix B of the user’s manual includes
additional information.
As in all scenarios, a CA-179-x USB cable is used to connect the /3000USB Series board to a USB2.0 port
on the host PC.
* Any of the following 68-conductor expansion cables can be used to connect the TB-100 option the SCSI
connector:
CA-G55 3 feet, ribbon cable.
CA-G56 3 feet, shielded expansion cable.
CA-G56-6 6 feet, shielded expansion cable.

IG-8 968492 DaqBoard/3000USB Series Installation Guide
Scenario 3: Using a TB-101 Terminal Board Option
In this setup a TB-101 terminal board is plugged directly into the 40-pin headers (J5, J6, J7, and J8) of the main board.
No cables are used in making this connection. “Stand-offs” are used to keep the boards from touching (instructions are
provided on the following page).
In this example 4 thermocouples are connected at TB7 (on the /3000USB board). This means that 8 analog channels
[to obtain 4 differential TC channels] are required (see following figure). Redundant connections must be avoided.
WARNING !
Before connecting TC wires, ensure that the associated analog
channels are not in use. Failure to do so could possibly cause
equipment damage and/or personal injury.
The TB7 terminal block [on the DaqBoard/3000USB] can be used to connect
up to 4 thermocouples. The first TC channel makes use of Analog Channel 0
for its positive (+) lead and Analog Channel 8 for its negative (-) lead. The
second TC channel uses analog Channels 1 and 9, and so on, as indicated in
the pinout to the left.
In DaqBoard/3000USB Series applications, thermocouples should only be connected in differential
mode. Connecting thermocouples in single-ended mode can cause noise and false readings.
Appendix B of the user’s manual includes additional information.

USB2.0 is recommended.

CAUTION
The discharge of static electricity can damage some electronic components. Semiconductor
devices are especially susceptible to ESD damage. You should always handle components
carefully, and you should never touch connector pins or circuit components unless you are
following ESD guidelines in an appropriate ESD controlled area. Such guidelines include the use
of properly grounded mats and wrist straps, ESD bags and cartons, and related procedures.
How to Mount the TB-101
Steps A through D relate to the following illustration.
A – After taking ESD precautions, remove the Hex
Nuts from the 5 existing standoffs.
B – Thread the new ST-6-7 standoffs onto the existing
standoffs. Tighten snug by hand.
C – Align the TB-101 with the new standoffs and
position the board in place.
D – Using the Hex Nuts (removed in Step A), secure
the TB-101 to the new standoffs. Tighten snug.
Over-tightening will damage the board.

Scenario 4: Using a DBK215
In this setup a DBK215 BNC Module is connected to the 68-pin SCSI connector via a CA-G56 shielded
cable. However, the use of other cables is possible as noted below. In this example we can also see that 4
thermocouples are connected at TB7 (on the /3000USB board). This means that 8 analog channels [to
obtain 4 differential TC channels] are required (see following figure). Redundant connections must be
avoided. A TR-2 power supply is being used, and is connected to the board’s external power connector.
A CA-179-x USB cable is used to connect the /3000USB Series board to a USB port on the host PC.
USB2.0 is recommended.
WARNING !
Before connecting TC wires, ensure that the
associated analog channels are not in use. Failure

DaqBoard/3031USB and DaqBoard/3035USB make use of J5 and J6 (two of the four 40-pin headers) for
analog expansion. Pinouts for these and the remaining two headers (J7 and J8) are included in this section.
A pinout for a 4-channel terminal board (TB7) is also included.

Locations of Signal Connectors and LEDs
Active LED (top)
Power LED (bottom)
LEDs: DaqBoard/3000USB Series boards have 2 LEDs located just right of the USB2 connector (see
figure). The LEDs function as follows:
Active LED (Top LED)
This LED is on whenever active USB communication is taking place between the DaqBoard
and the host PC. Note that the Active LED will be on solid during a data acquisition.
Power LED (Bottom 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 and a TR-2 [or TR-
2U] power adapter will be needed.
Note that when the board is first powered there will likely be a momentary delay before the
Power LED begins to blink, or come on solid.

WARNING !
Avoid redundant connections. Ensure there is no signal conflict between SCSI
pins and the associated header pin (J5. J6. J7. and J8). Also ensure there is no
conflict between TB7 (thermocouple connections) and the SCSI and/or the 40-
pin headers. Failure to do so could possibly cause equipment damage and/or
