WARNING!
Do not insert any foreign objects into any ventilation holes.
Do not use ungrounded power cords, power outlets or power strips. This product may only be connected to 3-wire
grounded AC outlets to avoid shock hazard.
Only qualified technicians should service this product as incorrect disassembly can create an electric shock hazard.
Safety Precautions Regarding Static Electricity
Always follow these important precautions to protect yourself and the product from harm.
1. Static discharge can damage the product. Before using the system, ground yourself to neutralize the static
electricity that might be in your body.

2. To avoid electrical shock, always disconnect the power from your system before you work on it.
3. Disconnect power before making any configuration changes to the system. The sudden onset of current as you
connect a jumper or install a plug may damage sensitive components.

Fourth edition: April 26, 2018
IMPORTANT: Please note CH02B is updated versions from older models CH02. There are two major updates.
1. A new type of DC8V output socket is used, which prevents damage to the camera by mistakenly plugging in
triggering (3.5mm) plug into the 8V output. Older models WITHOUT 'B' uses Power Jack DC 2.5X5.5.
Please verify if you are using/purchasing correct power plugs.
2. Middle pins of trigger links are connected to middle pins of trigger outputs with diode isolated. This new
feature enables the pre-trigger module and auto-focus function.

1 Introduction
This Camera Hub is designed to provide a 3D Stereophotogrammetry scanning system with DC power supplies and
diode isolated camera trigger signals to DSLR cameras. One Camera Hub can serve up to 8 cameras with DC power
and trigger signals.
2 Installation
2.1 Unpacking
Inspect the product for any possible signs of external damage or loose or damaged components. If the module is
visibly damaged, please notify our service department or our local sales representative immediately.
A damaged camera hub should not be used within your system.
2.2 Installation
The Camera Hub should be securely fastened before plugging in any cables.
Please follow the steps below to install the Camera Hub on your system.
Step 1: Ground yourself to neutralize the static electricity that might be in your body.
Step 2: Make sure the power is OFF. Plug in camera power cables and camera trigger cables into the power ports
and trigger ports respectively.
Step 3: Plug the trigger link cable into the Trigger Link socket of your Camera Hub to link several Camera Hubs
together.
Step 4: Plug a trigger source (e.g. remote controller, or control box) into the other Trigger Link sockets of your
Camera Hub to provide the trigger signal.
Step 5: Plug the AC power cord into the power sockets both in the Camera Hub and the AC power source.

3 Power and Trigger outputs
3.1 Overview
Maintaining stable signal connections is essential for sending and receiving data correctly. A good signal connection
can prevent costly damage to your hardware devices.

3.3 Power outputs
/O Connector Signal Description
There are 8 channels of DC 8V outputs (no load). Each channel can output up to 1A DC current. This works well with
Canon brand products. Please confirm that the camera hub will work with your cameras BEFORE plugging them into
the power sockets.
3.4 Trigger outputs
The 8 channel trigger outputs are isolated with diodes to eliminate any interference between the cameras.
3.5 Field Wiring Considerations
When using the Camera Hub in your system, external noise in the environment might significantly affect the
operation of your system if due precautions are not taken. The following measures will be helpful in reducing possible
interference from wires in between signal sources and the Camera Hub.
• The signal cables must be kept away from strong electromagnetic sources such as power lines, large electric
motors, circuit breakers, or welding machines because they may cause strong interference.
• Avoid running the signal cables through any conduit that might have power lines in it.
• If you must place your signal cable parallel to a power line with high voltage or high current running through it, keep
a safe distance between them or position the signal cable at a right angle to the power line.
