2. Precautions
2.1. Guideline for Avoiding EMI and ESD
You should consider the EMI (Electro Magnetic Interference) and ESD (Electro-Static Discharge) problem
in the process of using the camera, to guarantee the camera to work in a relatively good electromagnetic
environment. The main measures are as follows:
1) USB cables certificated by USB IF with locking screw are recommended.
2) Using shielded cable can avoid electro-magnetic interface. Shielding layer of the cable should conduct
to ground nearby and not until stretched too long. When many devices need conduct to ground, using
single point grounding to avoid earth loop.
3) Keep your cameras away from equipment with high voltage, or high current (such as motor, inverter,
relay, etc.). If necessary, use additional shielding.
4) ESD (electro-static discharge) may damage cameras permanently, so use suitable clothing (cotton)
and shoes, and touch the metal to discharge the electro-static before operating cameras.
2.2. Environmental Requirements
1) Housing temperature during operation: 0°C ~ 45°C, humidity during operation: 10% ~ 80%.
Storage temperature: -20°C ~ 70°C.
2) To avoid collecting dust in the optical filter, always keep the plastic cap on cameras when no lens is
mounted.
3) PC requirement: Intel Core 2 Duo, 2.4GHz or above, and 2GB memory or above.
4) USB3.0 host controller requirement: Intel controller integrated in mainboard is recommend. Select
Renesas controller if external frame grabber is needed.
5) The cable must have a locking screw at the end of the device.
6) Make sure that cameras are transported in the original factory packages.
2.3. Camera Mechanical Installation Precautions
Camera installation requirements:
1) The screw and camera have a screw length between 2.5 and 2.7mm.
2) Screw assembly torque ≤1N.M. If the screw assembly torque is too large, it may cause the camera
thread stripping.

as: the USB3.0 cameras' driver program.
2) Interface Library (API): This package provides the camera control interface library and the image
processing interface library, supports the user for secondary development.
3) Demonstration Program (GalaxyView.exe): This demonstration program is used to display the camera
control, image acquisition and image processing functions, the user can control the camera directly
by the demonstration program, and the user can develop their own control program based on the
camera interface library.
4) Sample: These samples demonstrate cameras' functions, the user can easily use these samples to
control cameras, or refer to the samples to develop their own control programs.
5) Programmer's Manual: This manual is the users programming guide that instructs the users how to
configure the programming environment and how to control cameras and acquire images through the
camera interface library.
You can download the latest software package from the website: www.daheng-
imaging.com/en/Downloads.
3.1.2. User Software Interface
After installing the MERCURY series camera software package, the user can use the demonstration
program and the samples to control the camera, also the user can control the camera by the program
which is written by the user themselves. The software package provides three kinds of program interface,
the user can select the suitable one for use according to their own requirements:
1) API Interface
In order to simplify the users' programming complexity, the package provides the general C programming
interface GxIAPI.dll and image processing algorithm interface DxImageProc.dll for the user to control the
camera, and provides the samples and software development manual which are based on these interfaces.
The API interface supports C/C++/C#/Python, etc.
