and peripheral devices
4. How to Operate
(4-1) Connection method
● Connection
Refer to the connection example between the camera and peripheral devices (Fig. 4-1).
(1) Remove the cover of the lens attachment section and
attach a lens (option).
(2) Connect the camera head to a power supply
unit(option) with a camera cable (option).
The maximum allowable length for TAKENAKA SYSTEM
standard camera cable(6P12G-series) is 20 m.
(3) Set the camera operation modes in accordance with the
setting instructions for the operation modes and the shutter
speed that are described in another section.
(4) Connect the digital output connectors on the rear of the
camera to the input terminals of the image processing units
(frame grabber board, computer, etc.) with digital cables
(option) conforming to Camera Link . The maximum
allowable length between the digital output connector of
the camera and the input terminal of said image processing
unit is 10 m.
(5)Confirm the connecting condition before turning on the power switch
of the camera. In 1 or 2 seconds after the power is turned on, the LED operation indicator on the rear panel of the
camera changes from orange to green to show that the camera is in operation.
(Note) The maximum allowable lengths of the camera cable and the digital cable aforementioned are not for the purpose
of guaranteeing the operation of the camera. Proper image signals may not be obtained even when the cables are
within the allowable ranges, depending on the installation conditions of the camera, cables in use and others.
● Application of test pattern
This equipment has the function of generating test patterns. This test pattern allows the user to confirm the
appropriateness of the connection between the camera and PC as well as the setting of the board to some extent
when used during the initial setup process for the connection with the capture board and others.
[Important]
(Note) Make sure to turn off the power switch of the camera before connecting or disconnecting the camera cable.
If the cable is connected or disconnected while the power is supplied, troubles may be caused.
(Note) Make sure to turn off the camera and connected devices in advance when the camera is connected.
(Note) When a power supply unit other than Takenaka
’s camera power supply units that are separately sold is used, make sure
that it complies with the following rated specifications:
Power supply voltage: DC12V±10%
Current capacity:
900mA or over (recommended value)
Take into consideration the fact that transient current of about 1.5A flows when power is applied.
Ripple voltage:
50mVp-p or less (recommended value)
Connector:
6 pin connector 1 pin (GND), 6 pin (+12VDC)
(Note) Some power supply units other than TAKENAKA
’s products have different layout of power connection pins. Make sure to
check the compatibility of the power supply unit and the camera connection pins in advance.
Carefully note that any failure associated with power application to out-of-specification pins and others is subject to
charged repair.
(4-2) Input of Vinit signal (asynchronous trigger signal)
● How to input Vinit signal
If the camera is used in the asynchronous shutter mode, the Vinit signal (asynchronous trigger signal) must be input
from the user unit. The Vinit signal is input from Pin (4) of the
“POWER” connector (6 pin connector) on the rear of the
camera, or is input as the CC1 signal of the
“Camera Link” connector.
If the camera is connected to the power supply unit PU100 with a Takenaka
’s 6P12G series cable, connect the Vinit
signal (asynchronous trigger signal) to the trigger input terminal of the power supply unit (PU100).
(Note) OR operation (negative OR) is implemented inside the camera between the Vinit1 input signal of
“POWER”
connector and Vinit2 input signal as CC1 signal of
“Camera Link” connector.
If either one of those are fixed to the active level, the Vinit signal (logical sum) is also fixed to the H level and the
trailing edge signal cannot be obtained. This would result in failure in starting up the asynchronous shutter
operation. Make sure to fix the input signal on the unused side to the non active level, keep it at high impedance
level or open state (no connection).
