INSTALLATION GUIDE
NI CB-37F-LP
Connector Block for 37-Pin D-Sub Devices
This installation guide describes how to install and connect signals to the
NI CB-37F-LP connector block for use with devices with a 37-pin D-Sub
connector.
Introduction
The CB-37F-LP is a connector block assembly consisting of a printed
circuit board and 40 screw terminals. The connector block assembly
connects directly to the front panel of National Instruments 37-pin D-Sub
devices, eliminating the need for an external cable. It also can be cabled
using a 37-pin cable.
The CB-37F-LP allows you to easily connect analog input, analog output,
counter/timer, and digital I/O signals to your National Instruments device.
The 40 screw terminals allow access to every pin on the connector, plus
three shield screw terminals for use with a shielded cable.
Caution The CB-37F-LP is not designed for input voltages greater than 42 Vpk, even if you
install a voltage divider that reduces the voltage to within the input range of the DAQ
device. Input voltages greater than 42 Vpk can damage the CB-37F-LP, any device
connected to it, and the host computer. Overvoltage also can cause an electric shock hazard
for the operator. National Instruments is not liable for damage or injury resulting from such
misuse.

Safety Information
Cautions Do not operate the device in an explosive atmosphere or where there may be
flammable gases or fumes.
Do not operate damaged equipment. The safety protection features built into this device
can become impaired if the device becomes damaged in any way. If the device is damaged,
turn the device off and do not use it until service-trained personnel can check its safety.
If necessary, return the device to National Instruments for service and repair to ensure that
its safety is not compromised.
Do not operate this equipment in a manner that contradicts the information specified in this
document. Misuse of this equipment could result in a shock hazard.
Do not substitute parts or modify equipment. Because of the danger of introducing
additional hazards, do not install unauthorized parts or modify the device. Return the
device to National Instruments for service and repair to ensure that its safety features
are not compromised.
You must insulate all signal connections to the highest voltage with which the CB-37F-LP
can come in contact.

Connections, including power signals to ground and vice versa, that exceed any of the
maximum signal ratings on the connector block can create a shock or fire hazard, or can
damage any or all of the boards connected to the host computer, and the connector block.
National Instruments is not liable for any damages or injuries resulting from incorrect
signal connections.
Clean the device and accessories by brushing off light dust with a soft non-metallic brush.
Remove other contaminants with a stiff non-metallic brush. The unit must be completely
dry and free from contaminants before returning it to service.
Connecting the Signals
Refer to the help file for the NI 37-pin device for a list of signals available
on the CB-37F-LP.
Refer to Figures 1 and 2 as you complete the following steps to connect
signals to the connector block.

1. Use wire cutters and wire insulation strippers to strip no more than
7 mm of insulation from the wire ends.
2. Loosen the screws in the screw terminals with the 0.10 in. slotted
screwdriver.
3. Insert the stripped wires into the screw terminals, and tighten the
screws with the 0.10 in. slotted screwdriver. No bare wire should
extend past the screw terminal. Exposed wire increases the risk of short
circuits and failures.

Mounting the Connector Block to the Device
Refer to Figure 3 as you complete the following steps to mount the
connector block on the PCI device I/O connector.
Figure 3. Mounting the CB-37F-LP to a 37-Pin Device
Caution The connectors of both the PCI device and the connector block are polarized.
You can attach them in only one way. Do not force the connector block when inserting it
into or removing it from the PCI device I/O connector. Make sure that the computer is
powered off before inserting the PCI device.
1. Install the PCI device into the computer as described in the DAQ Quick
Start Guide. You must install the CB-37F-LP connector block on the
PCI device after the device is installed in the computer.
Caution The CB-37F-LP is not designed for input voltages greater than 42 Vpk, even if you
install a voltage divider that reduces the voltage to within the input range of the DAQ
device. Input voltages greater than 42 Vpk can damage the CB-37F-LP, any device
connected to it, and the host computer. Overvoltage also can cause an electric shock hazard
for the operator. National Instruments is not liable for damage or injury resulting from such
misuse.
2. Install the CB-37F-LP on the PCI device by screwing in both
connector block mounting screws with the Phillips screwdriver.
