1 The connector specifications
A. Camera Link connector: SDR (3M) or equivalent
Caution: This product is not PoCL type. Only apply 12Vdc power through the power/IO connector.
B. Power/IO connector: HR10A-7R-6PB (Hirose) or equivalent
This connector is for a 12Vdc power input and the input and output signals.
Trigger input signal can be assigned through the camera setting communication.
1.1 Pin assignment
A. Camera Link Connector
B. Power/IO Connector
Notes:
Trigger input signal can be assigned either on Camera Link connector (CC1) or on the No. 2 pin of the power/IO
connector through the camera setting communication.

1.2 The signals of the power/IO connector
The input and output signals of the power/IO connector can be change through the camera setting
communication.
The input and output signals of the power/IO connector can be change through the camera setting
communication.
Note.1: Please change “F0H” address data of the register when change the signals of the power/IO connector.
Please change “C0H” address data of the EEPROM when save the signals of the power/IO connector
setting.
“F0H” address data could not save to the EEPROM.
Note.2: Output trigger signal has below delay from the trigger signal input:
30CLK (Approximately 470 useconds)
Note.3: Please change “12H.5” when use the trigger signal input from the power/IO connector.
Note.4: The exposure time is “High” while the camera exposures.

3.2 Pulse width trigger mode
In this trigger mode with positive polarity, the camera exposure starts at the rising edge of the trigger pulse and
stops at the falling edge of the trigger pulse. Therefore, In the case of the exposure positive polarity is selected, the
exposure periods are the high states of the trigger pulse.
3.2.1 Pulse width trigger mode (V-Reset)
Note.1: The camera does NOT switch to the normal mode when the long exposure mode is set
Note.2: The video output is going to be V reset by the next internal HD signal immediate after the exposure is
finished.
Note.3: The exposure time sets by the pulse width of the trigger signal.
