External Sync
The TM-1400 accepts an external sync. of standard
HD and VD at TTL level for general locking to a system
sync. and clock. External sync. is available for 30-frame
mode only. The frequency requirement is as follows:
fHD = 31.09 KHz ±2%
fVD = 29.5 Hz ±2%
(Internal Master clock = 100.0 MHz,
Pixel clock = 25.0 or 50.0 MHz)
Please contact PULNiX for TM-1400 timing charts.
No-delay Shutter and Read-out-inhibit
For multiple-camera applications such as 2D or 3D
measurement and multi-angle inspection, simultaneous
image capturing at an exact shutter timing for all
cameras is a critical requirement. The TM-1400’s async
pulse width control mode provides no-delay shutter
as standard. Regardless of internal pulse timing, it
discharges at VINIT’s leading edge and transfers charges
at the trailing edge of the pulse. Even though each
camera runs with slightly different H and data clock
timing, image capturing is exactly simultaneous.
The TM-1400 also has read-out-inhibit control (ROI)
to control the vertical clock start (Async Shutter #9).
When ROI is low, V-clock is stopped and the transferred
charges remain in the vertical shift registers, which
works like CCD memory. When ROI is high, it clocks out
the CCD data. This helps a single frame grabber process
multiple images in pipeline processing (sequential
process).
Mode Switches
Various modes can be implemented with the rear
panel-mode selection switch and Up/Down switch as well
as RS-232 external control. When RS-
232 is connected, the command over-
writes the rear panel switch settings.
