Assembling Your 2250 Light
This chapter describes how to assemble and set up a 2250 Light. It provides a brief description
and an associated diagram showing the instrument’s components and the various input and
output connections. This enables you to start getting familiar with the instrument, while
assembling a system.
This is followed by an overview of the hardware components, showing all the main
configurations of the instrument and its accessories.
Finally, instructions are provided that explain how to assemble standard and optional hardware
components used in your system. Once you have followed the assembly instructions, your
Hand-held Analyzer will be ready to make measurements.

2.1.1
What is Different with G4 Hardware?
The differences in the G4 hardware compared to previous versions include:
•
A brighter screen which is easier to view in direct sunlight
•
The CF card slot is removed and replaced by a second SD card slot to take advantage of
the SD format’s dominance in the storage and Wi-Fi markets
•
The USB connector changed from USB 1.1 Mini B to USB 2.0 Micro AB. Besides the
faster connection speeds of USB 2.0, the Micro USB connector is more common
•
A second standard USB Type A socket was added for easier connection to USB
peripherals like modems, printers, GPS receivers, and USB to RS–232 adaptors
•
A 100 Mbps LAN connector is available
•
A Trigger Input socket for external trigger of signal recordings
•
An Input socket and an Output socket (both currently not in use)
