2.Precautions
© China Daheng Group, Inc. Beijing Image Vision Technology Branch 3
2. Precautions
2.1. Guidelines for Avoiding EMI and ESD
1) CAT-5e cables or above with S/STP shielding are recommended.
2) Using shielded cable can avoid electro-magnetic interface. Shieldinglayer 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) Try to use camera cables that are the correct length. Avoid coiling camera cables. If the cables are
too long, use a meandering path rather than coiling the cables.
4) Keep your cameras away from equipment with high voltage, or high current (as motor, inverter, relay,
etc.). If necessary, use additional shielding.
5) 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) NIC requirement: Intel Pro 1000 NIC or higher performance Gigabit LAN confirming to IEEE802.3af
standard, CAT-5e or CAT-6 cables, less than 100m, Gigabit Switch confirming to IEEE802.3af
standard.
5) Make sure that cameras are transported in the original factory packages.
2.3. Camera Mechanical Installation Precautions
1. Camera installation requirements
1) The screw and camera have a screw length between 2.5 and 2.7 mm.
2) Screw assembly torque ≤ 1N.M. If the screw assembly torque is too large, it may cause the camera
thread stripping.
2. DAHENG tripod adapter instructions
1) M3 * 6 cross recessed cheese head screws are required.
2) After the screws pass through the tripod adapter, they are directly assembled with the camera threads.

IEEE 802.3af compliant PSE (Power sourcing equipment) to power the MER2-G-P camera.
2) Via the Hirose I/O port
The MER2-G (-P) camera can get power from the 8-pin Hirose I/O port via a standard I/O cable.
Nominal operating voltage is +12V (±10%) ~ +24VDC (±10%).
When you supply power to the MER2-G-P camera both via the camera’s RJ45 jack and via the 8-pin
Hirose I/O port, the camera will get power via the Hirose I/O port.And if you cut off the Hirose I/O port, the
camera will get power via PoE and may restart.
1) Voltage outside of the specified range can cause damage.
2) The plug on the cable that you attach to the Hirose 8-pin receptacle must have 8 female pins.
Using a plug designed for a smaller or a larger number of pins can damage the connector.
See the Figure 7-1 of section 7.3 for the definition of IO port.

3.3.2. Driver Installation
The steps to install the GalaxySDK under Windows are as follows:
1) Download the corresponding version of the installation package from www.daheng-
imaging.com/en/Downloads.
2) Run the installer.
3) Follow the instructions of the installation wizard to complete the installation process. During the
installation process, you can choose the camera interface you need (USB2.0, USB3 Vision, GigE
Vision, etc.).
During the installation process, especially when installing the *.sys file, you must always pay attention to
the anti-virus software to intercept the driver. If intercepted, it may cause the driver installation to fail.
3.4. Camera IP Configuration
The IP Configurator provided by GalaxySDK eliminates the need for users to configure IP for hosts and
devices. Implement one-click configuration IP. You only need to follow the steps below to configure the
camera IP. For details on how to use the tool, please refer to section 9.1.
1) Connect the GigE camera to the network port of the current host.
2) Open the GigE IP Configurator of the installation package.

4.1. Explanation of Important Parameters
4.1.1. About Spectral Response
QE: Which is the ratio of the average number of photoelectrons produced per unit time to the number of
incident photons at a given wavelength.
Sensitivity: The change of the sensor output signal relative to the incident light energy. The commonly
used sensitivity units are V/((W/m2) •s), V/lux •s, e-/((W/m2) •s) or DN/ ((W/m2) •s).
The spectral response graphs given by different manufacturers are different. Some graphs' ordinate is
relative sensitivity response, and abscissa is wavelength. Some graphs' ordinate is QE, and abscissa is
wavelength.
