(*1): The case that output low voltage on 15mA load. The output voltage could be higher voltage due to the generate voltage by the internal resister when the power consumption is large with low voltage output. Please evaluate carefully with the actual system.
(*2): The maximum voltage can be applied to connecting IO port as output IO port when external circuits connecting to IO port. This is equivalent to VCCext on Reference 4.
(*3): When external IO port is connected, control the currency less than 15mA on IO port. Please do not apply more than 15 mA to connecting IO port as output IO port when external circuits connecting to IO port.
(*4): The typical current value when high voltage input into Input port.

■Input Response Characteristics
Input Port Function
This function sets the input on Line Mode, then assigns Line as the input.
The following functions can be assigned as input.
1) Trigger Input
When select "input" assign port at the Trigger Source, the input signal can be assigned as Trigger.
The input signal can be switched to Active-Low (Line Inverter: true) or Active-High (Line Inverter: false).
(*) When the Line polarity changing by Line Inverter, the active polarity of input trigger signal is changed.
2) Line Status
This function monitors the signal status on the input Line.
The High level (Line Status: true) or Low level (Line Status false) status can be seen through the software.
3) Trigger Delay
As mentioned in the previous chapter, "Image acquisition and Camera Mode", each trigger can add to the duration of the input signal.
This Trigger Delay can add to the duration per µsecond.
Reference Input Circuit
CAM_RESET (Reference 1)
The camera resets while "CAM_REST pin" connecting to GND 5 seconds in this circuit.

The default camera setting is disable for this reset function. It is necessary to turn ON.

General Purpose Input (Reference 2)

Input Response Characteristics
The response characteristics of CAM_RESET (Reference1), General Purpose Input (Reference 2) are shown in the following diagrams
Td 0.07 µseconds
Tr 0.06 µseconds
Ts 4.87 µseconds
Tf 1.67 µseconds
The capable input trigger's pulse width is
Positive Edge: more than Ts + Tf
Negative Edge: more than Td + Tr
■Reference Output Circuit
Output Port Function
This function sets the Output to Line Mode, and then the Line is assigned as the output.
The following functions can be assigned when the IO port is used as the output signal port.
Line Source
The following list shows the configurable functions available through the Line Source.
The function that describes as "Enable" on "Changeable Polarity" is the configurable polarity on the Line Inverter (true, false).
No. Function Name Changeable Polarity
1) Off (Default) -
2) User Output -
3) Trigger Out Enable
4) Trigger Through Out Enable
5) Exposure End Out Enable
6) Frame End Out Enable
7) Frame Trigger Wait Enable
8) Transfer End Out Enable
9) Strobe Out Enable
10) Exposure Active Enable
1) Off (Disable)
Disable the output signal.
2) User Output (General Output)
High or Low level signal that sets on the software is output.
3) Trigger Out
The trigger signal that added "Trigger Out Delay (Output pulse delay time)" and "Trigger Out On Time (Output pulse width)" is output.
4) Trigger Through Out
The trigger input signal is output. (with a slight internal delay)
5) Exposure End Out
"Trigger Out on Time (Output pulse width)" activation time signal with set "Trigger Out Delay (Output pulse delay time)" is output when the expose was finished.
6) CFrame End Out (Sensor Readout End)
"Trigger Out on Time (Output pulse width)" activation time signal with set "Trigger Out Delay (Output pulse delay time)" is output when the sensor read out was finished.
7) Frame Trigger Wait
The camera is waiting for a frame start trigger currently.
8) Transfer End Out
"Trigger Out on Time (Output pulse width)" activation time signal with set "Trigger Out Delay (Output pulse delay time)" is output when one frame image transferring from camera was finished.
9) Strobe Out (Strobe Output)
"Strobe Out on Time (Output pulse width)" activation time signal with set "Strobe Out Delay (Strobe output delay time)" is output when the trigger signal is received.
10) Exposure Active (In Exposure Period)
The signal that activation time is exposure time is output.
