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 to a power supply unit
(option) with a camera cable (option).
The maximum allowable length of a camera cable
is 15 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 Camera Link connectors on the rear
panel of the camera to that of the image
processing units (frame grabber board etc.) with
the dedicated Camera Link cable (option).
[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 product that are separately sold is used, make sure that it
complies with the following rated specifications:
Power supply voltage:
DC12V±10%
Current capacity: 450mA or over
Take into consideration the fact that inrush current of about 1A flows in when power is applied.
Ripple voltage:
50mVp-p or less (recommended value)
Connector:
12 pin connector 1 pin (GND), 2 pins (+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 side unit.
The Vinit signal is input from Pin (6) of the “POWER” connector (12 pin connector) on the rear of the camera, or is
input as the CC1 signal from the “Camera Link” connector.
If the camera is connected to the power supply unit, PU100, with a cable of Takenaka’s 12W series, 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 Vinit1 input signal from Pin (6) of “POWER”
connector and Vinit2 input signal as CC1 signal of “Camera Link” connector (see the figure below).
(Note)
If either one of those are fixed to the L level (active state),
the Vinit signal (logical sum) is also fixed to the L 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 H level, to keep it at high impedance level or
open state (no connection).
