This installation guide describes how to install and configure your
BNC-2110 accessory with an E Series or waveform generation DAQ
device. Waveform generation DAQ devices refer to 671X and 672X
devices.
The BNC-2110 is a desktop and DIN rail-mountable BNC adapter you
can connect directly to data acquisition (DAQ) devices. The BNC-2110
includes 15 BNC connectors and a terminal block with 30 pins.
The BNC-2110 has a 68-pin I/O connector that connects to the E Series and
waveform generation DAQ devices. The BNC-2110 is ideal for simplifying
connections between your measurement apparatus and your DAQ device
in laboratory, test, and production environments.
To set up and use your BNC-2110 accessory, you need the following:
BNC-2110 BNC Adapter
BNC-2110 Desktop and DIN Rail-Mountable BNC Adapter
Installation Guide
E Series or waveform generation DAQ device and the appropriate
cable
Small straight-blade screwdriver (supplied)
