TM-4100GE Hardware
TABLE 8.
Electronic Shutter Speeds
With VINIT high (CC1), the CCD keeps discharging. With an active low pulse to VINIT, the camera
resets and purges the charge momentarily. Then it starts integrating for the period of shutter control set
by either an external pulse width or internal shutter control. Progressive scanning permits a full 2048
lines of vertical resolution, as compared to a conventional CCD camera which captures only half the
vertical lines per shutter.
8.4 Integration
The CCD imager of the TM-4100GE can be exposed for longer than the normal scan timing of 1/200
sec. This integration feature provides extra sensitivity for dark-environment applications. The
progressive scan imager permits a full frame of resolution in non-interlace format. Integration is
achieved by controlling CC2 Camera Control line through the Gigabit Ethernet cable to low (GND) or
providing pulse-width control up to 1 sec. Please refer to Figure 26, “12P-02S Interface Cable
(optional),” on page 37 for pin-out information on the 12-pin connector.
8.5 External Sync
The TM-4100GE accepts an external sync of standard HD and VD on CC3 and CC4 of the Gigabit
Ethernet connector for general locking to an external source.The frequency requirement is shown in
Table 8 on page 45. The tolerance is ±2% horizontal frequency.
8.6 Asynchronous Reset
The TM-4100GE camera includes three modes to control the asynchronous reset and shutter speed:
•
Async No Shutter (recommended for strobe applications)
• Internal Shutter Speed Control
•
External VINIT with Pulse Width (No-Delay Shutter) and ROI (read-out-inhibit)
