oCam-1CGN-U-T User Manual 3. TRIGGER SIGNAL Trigger Signal Connector Specifications The oCam-1CGN-U-T accepts a external trigger signal through the 3-pin connector on the back side of the camera. The pin descriptions are as follows: Pin 1: Signal ground Pin 2: For trigger signals in the range of 3V ~ 5V DC Pint 3: For trigger signals in the range of 5V ~ 24V DC Input pin for Trigger Signal (3V ~ 5V) Input pin for GND Trigger Signal (5V ~ 24V) Figure 6.
oCam-1CGN-U-T User Manual Figure 7. Trigger input circuit Trigger Signal Specifications The camera acquires image at the falling edge of the trigger signal. Depending on the trigger signal, the camera operates in one of the 3 modes described as follows. One Shot Mode With this mode, the camera acquires one frame of image. The trigger signal should maintain the low level at least 1 msec(T1). Figure 8. One shot mode Multi Shot Mode With this mode, the camera acquires multiple frames of images.
oCam-1CGN-U-T User Manual Figure 9. Multi shot mode Continuous Mode With this mode, the camera acquires images continuously at the interval set as camera speed. For example, in the following figure, the camera starts to acquire the image after the trigger signal goes low and acquires the images at the interval of T3 set as the camera fps. When the trigger signal goes high, the camera stops to acquire the images. Figure 10. Continuous mode www.withrobot.
oCam-1CGN-U-T User Manual 4. HOW TO USE ON WINDOWS SYSTEM Connection to Windows PC Connect the USB cable, either USB 2.0 or USB 3.0, to the USB port of the computer. After the camera is detected, the computer will show a message that the camera is connected.

oCam-1CGN-U-T User Manual 5. NOTES On the oCam-1CGN-U-T, you can adjust the focus by rotating the lens by hand. Therefore, in a vibrating environment, the lens can be loosened by being rotated by itself. To prevent this, it is recommended to lock the lens by using the supplied lens lock ring after you finish adjusting the focus. To change the lens, you need to loosen the lock ring first before you take out the lens from the holder. www.withrobot.
oCam-1CGN-U-T User Manual 6. TRIGGER SIGNAL BOARD The oCam-1CGN-U-T can be used with any signal source as long as it meets the input signal specification. It is recommended to use the mTrigger, however, which is a trigger signal board supplied by the WITHROBOT Inc. for full compatibility and verified operation. The mTrigger signal board supports the following 4 signal modes which are all user programmable to set the detailed signal parameters.
