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 V

pk

, 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 V

pk

 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.
