Variable gain mode from 6dB to 22dB (or max.

32dB). Up and down switch or RS-232 (8-bit)

controls continuous gain changes.

Select four preset gains of 9, 12, 18, 22dB

(18dB factory set).

Direct digital output without memory.

Digital output: 1-bit, 12 frame/sec. (20MHz).

Must use frame grabber to capture video.

Analog output: SVGA output of 47 frame/sec.

Memory mode:

Digital output: 8-bit, 12 frame/sec. Can grab

images in built-in frame buffer.

Analog output: No scan conversion. 12

frame/sec.

Varies A/D high (top) and low (bottom) reference

voltages for various dynamic range control and

digital black level control.

Adjust top reference: Control digital saturation

level and gain.

Adjust bottom reference: Control digital black

level (offset) can be controlled.

Switches real time image and freeze image in

the frame buffer.

Selecting async reset: Each image captured

asynchronously will output as a frozen image.

For integration: It is necessary to enable the

freeze (ENINT).

Save and read the set parameters.

Changes shutter speed from 1/12 sec. to

1/39,000 sec. by increment or deincrement of

1H (80µsec.).

Clears V-shift registers upon async trigger and

reduces upper portion of smear.

Monitor with Continuous Sync

The TM-1300 provides scan conversion video output which

can be displayed with a standard computer monitor for easy

focusing and optical alignment or on-site maintenance. The scan

converted frequency is:

Hsync=49.5kHz, Vsync=47.2Hz

Note: Some SXGA monitors may not sync. Contact PULNiX

for more information.

The video output is equal amplitude R G B (3 channel) for

full B/W display with a standard color SVGA monitor. The analog

output is available from the BNC connector for single channel

1.0 Vp-p composite video output. Analog sync output is continuous

even if async reset mode is selected, so that the monitor maintains

steady images without interruption or jumping images.

Mode Selection

Mode selection is available from either the back plate switch

or RS-232C remote control.

Str

obe Output

The TM-1300 outputs a strobe control signal for asynchro-

nous shutter and strobing applications. This output is a useful

tool for applications such as intelligent transportation systems,

laser studies and background cancellation imaging. The strobe

output is provided 1 1/2H (120µsec) prior to the CCD charge

transfer gate. The output is RS-422 differential and each polarity

(Strobe+: pin 7, Strobe-: pin 8) can be used as a positive pulse or

negative pulse with single ended TTL.

Note: The strobe may not work properly when the shutter

speed is selected at 1/9,600 and 1/39,000, as the interval

between the strobe and the transfer gate is only 1/2H (40µsec).

Fast Dump Mode

The fast dump mode is designed to reduce upper side

smear from point light sources such as laser and vehicle head

lights. At async reset, it clears both the photosite and vertical

shift registers of the CCD imager. As the fast dump takes

6.08 msec after the async reset and image output follows with

selected shutter speed, the image capturing timing must be

delayed by this amount. The strobe output adjusts the delay

automatically when the fast dump mode is selected.
