Introduction
The MEMRECAM GX-5 is designed to analyze images moving at speeds not
visible to the naked eye.
The MEMRECAM GX-5 has an unitized configuration with an IC memory as the
storage medium and the camera head structure that it divided and so is a high
speed digital camera that possesses the identical compact nature of a high speed
film camera, the same immediate playback function of a high speed video camera,
and can handle the digital data from all of the images after recording.
The MEMRECAM GX-5 easily performs the high speed photography necessary for
high speed techniques. Photography and analysis without the use of a computer is
possible with the included software containing the functions of remote operation
from a computer with the simple operation of the included remote controller, image
storage to a USB compatible external storage medium using the USB port and live
image display using the viewfinder or monitor.
The MEMRECAM GX-5 is designed for high speed and superior image quality
requirements. Photography at a resolution of 640 x 480 pixels is possible with a
photographic speed of 1,000 frames per second. High speed photography is
possible up to 100,000 frames per second (32(H) x 16(V)) using a split frame. Also,
high speed image transmission to the control computer can be performed
according to the high speed network (10BASE-T, 100BASE-TX, 1000BASE-T).
The MEMRECAM GX-5 performs high speed photography in demanding test
environments, and is compact, durable, vibration and shock resistant, as well as
possessing properties resistant to magnetism.
This user's manual provides the specifications, operating methods, interface with
peripheral equipment and system expandability information to use the
MEMRECAM GX-5 with these features.

Handling Precautions
Safety alert symbol
This is a「Safety Alert Symbol」.
This symbol is intended to alert the user of items or operations that could
be dangerous to oneself or others during the use of this device. Carefully read
the messages accompanying this symbol and follow the instructions to safely
use this device.
Grounding terminal symbol
(00200)
- 3 -
This symbol is displayed in areas with grounding terminals. If not grounded, electrical
shock may occur when metal or other parts of the device are contacted. Do not ground,
due to the dangers involved.
If a 3P-2P conversion plug is used to connect to the power outlet, connect the grounding
wire of the conversion plug to the grounding terminal.
High voltage warning symbol
This symbol is displayed in areas of dangerously high voltage.
Remove the power cable from the outlet when replacing fuses.
Do not remove the cover of this device. Electrical shock could occur if this device is
handled with the cover removed even if the power switch is OFF.

Precautions for Use
Caution Verify Power Input
Power input to the system should be AC 100~240V/47~63Hz when using the AC adapter
enclosed, and DC20~32V when using DC power or batteries. Please verify power voltage,
frequency and polarity prior to connecting to power.
Caution Operating Environment
・Use in locations where the ambient temperature is 0~+40°C and the RH is 30~80%. Use
where there is no condensation.
・Store where the ambient temperature is -10~+60°C and the RH is 20~80%. Store where
there is no condensation.
・Avoid using in locations with smoke, corrosive gases or strong magnetism.
・Do not store in locations subject to direct sunlight, rain or salt water.
・Do not use in locations with excessive dirt, dust, sand or moisture.
Caution Vibration and Shock
The MEMRECAM GX-5 is a model designed and manufactured to withstand strong
vibration and shock, and may be installed in vehicles. However, please take the following
precautions.
・The vibration and shock resistant properties are only present in the DRP unit and the camera
head unit. There are no vibration and shock resistant properties present in the AC adapter or
JPAD3. Please visit your retail outlet to purchase power sources and lenses with vibration and
shock resistant properties.
・If connecting a cable to the connector of the main camera unit, all of the connectors will have
shock and vibration resistant properties.
・There are ten M10 screw openings on the back of the camera for use when installing
attachments with vibration and shock resistant properties to the main camera unit.
(00200) - 4 -

Caution Handling the DRP Unit
The inside of the DRP unit contains parts that are precisely manufactured and installed.
Please keep the screws in the DRP cover tightened and do not open the cover under any
circumstances (even if the DRP unit does not operate properly). It may not be possible to
recover the functions of the camera.
Caution Generation of Heat
Heat will be generated during operation of the system but it will not interfere with operation.
If an abnormal amount of heat is generated, turn off the power and unplug from the outlet.
Directly contact the retail outlet or this company.
Caution Handling the Lens Mount
Remove the lens or cap on the lens mount of the camera to view the camera contents. Do not
touch or place items inside. This could damage the optical system, and any dust could
adversely affect the image.
Caution Handling Cables
Turn the power off while connecting or removing cables.
With the power still on, connecting or removing cables could result in a malfunction, or
electrical shock.
Do not put metal parts into the connectors.
Caution Handling the Battery
The MEMRECAM GX-5 is equipped with a standard memory backup battery so do not place
in direct sunlight in vehicles, near fire, on the stove or any location with high temperatures.
The battery could leak and adversely affect performance of the battery of its life.
Do not use the memory backup batteries for any other purpose. The battery could leak,
generate heat or malfunction.
Contact a retail outlet for replacement memory backup batteries.
Caution Handling When Moving or Transporting
Use the special carrying case for this product when moving or transporting.

Caution Amplification of Sensor Noise
The temperature of the image sensor used in this product alters the screen noise. This noise
has a pattern that differs from the stationery pattern noise for each sensor. In this product,
noise reduction is performed by correcting the temperature changes as well as the stationery
pattern noise for the sensor.
If a finer image quality is desired, adjust the black balance immediately prior to photographing.
(Cf. 3-48 3.3.8 black balance)
Depending on the conditions and circumstances of use of the device, there may be malfunctions
other than those listed above. Please carefully read all of the user's manual for the device. Directly
contact the retail outlet if there are questions about this device.
Parts to be Replaced on a Regular Basis
・Clock Battery
The clock battery will last for approximately 8 years. Replacement cannot be made by the user so
please contact the retail outlet or this company.
・Memory Backup Battery
Please replace the memory backup battery approximately one year after purchase. If the discharge
rate accelerates or if there are differences in amount of use, please replace immediately. Replacement
cannot be made by the user so please contact the retail outlet or this company.
Warranty
The warranty period for the MEMRECAM GX-5 is for one year after delivery.

1. EST1 Input
When the MEMRECAM GX-5 is set to EST1 mode, the Exposure Start Signal is synchronized to the
input signal received on the Full Wired J1 cable, branch P11 (EST1) from an external pulse generator.
Please refer to / 7 / Specifications / APPENDIX B - Exposure Start Signal (EST) and Event Signal /
for additional details.
2. EST2 Input
When the MEMRECAM GX-5 is set to EST2 mode, the Exposure Start Signal is synchronized to the
input signal received on the Full Wired J3 cable, branch P32 (EST2) from an external pulse generator.
Please refer to / 7 / Specifications / APPENDIX B - Exposure Start Signal (EST) and Event Signal /
for additional details.
3. ARM Command Input
The MEMRECAM GX-5 will enter ARM mode when a signal is supplied to the Full Wired J2 cable,
branch P20 (ARM-I). Please refer to / 7 / Specifications / APPENDIX D - Discrete Interface/ for
additional details.
4. IRIG-B Input
When the MEMRECAM GX-5 is set to IRIG-B Synchronous mode, the camera is synchronized to the
input signal received on the Full Wired J3 cable, branch P33 (IRIG-B) from an IRIG time clock
