Instrument Rear Panel
The rear panel of DI-4718B instruments provide access to power and interface connections, ground, status LED, and
USB drive port. The rear panel can vary depending on your model.
Power Input Jack
Power must be applied with the included power adapter or with an alternate appropriate source (9-36VDC, 15 watts
max). Power over Ethernet (PoE) instruments derive power through the Ethernet port.
Ground Lug
This ground lug should always be connected to a solid chassis or earth ground. This connection is mandatory for the
unit to meet CE guidelines.
Ethernet Port
The Interface port allows you to connect the instrument to your PC via Ethernet cable. When in Ethernet mode the
USB connection is inactive.
Mini-B USB Port
The Interface port allows you to connect the instrument to your PC via USB cable. When in USB mode the Ethernet
cable and USB thumb drive are inactive.
USB Drive Port
Allows you to record to any USB flash memory device. Not all flash memory is fast enough to record at higher sam-
ple rates. Use the provided USB flash drive for rates below 20,000 S/s Throughput. The mini-USB interface cannot
be used in conjunction with the USB Drive.
Status LED
Indicates what mode the instrument is currently in. Use the chart on the rear panel of the instrument for quick refer-
ence. See “Mode LED Indicator” on page 18 for a list of modes.
