Note: • Do not input external VD signal at Pin No. 7 of the 12-pin Hirose connector, as it may disturb the
external trigger function.

Integrate Mode

The standard factory setting for the TM-77X camera is FRAME MODE.
In addition to the External Trigger modes, there is an External Integrate mode on pin 12 on the 15 pin
connector. This allows frames to continually integrate until this input pin is released.
To use this mode:
Input:
Set MFI mode: "VD mode"
Set MFI Termination: "Hi Z"
Set Trigger mode: "Off"
Set Vertical mode: "Field" or "Frame"
3.2.4

Vertical Mode

The standard factory setting for the TM-77X camera is FRAME MODE.
In Field Mode, two horizontal rows are scanned together, changing the pair at each interlace scan. The
sensitivity of the CCD is doubled for one field of integration, therefore it can obtain the same sensitivity as in
Frame Mode in half the period of time. This is an advantage when the shutter is used often. Because of the
alternating two-row scanning, Moire is almost unnoticeable. While the vertical resolution is not as good as in
Frame Mode, it is sufficient to view the full vertical resolution of the TV format. Note: Only odd fields are
output in this mode. Field Mode cannot provide full frame resolution with strobe lighting applications
