9.2.5 Note for 100BASE-TX connection

In order to use 100Mbps network, 100BASE-TX and Full Duplex are available. Half

Duplex cannot be used.

In the case of connecting on 100BASE-TX, the maximum packet size should be 1500

bytes.

In the case the of connecting on 100BASE-TX, the specifications such as frame rate,

trigger interval and so on described in this manual cannot be satisfied.

Pixel Type

Frame rate at Full Frame scan[fps]

RGB8_Packed

Approx. 2

RGB10V1_Packed,RGB10V2_Packed

Approx.1.5


Note: The above frame rates are based on approx. 70Mbps of total frame transfer data.

9.3. Basic Functions

9.3.1 Basic construction
The AT-140GE is a 3CCD camera equipped with F4, 1/2 inch prism optics. Red, green and blue
color signals are taken from each 1.45 mega CCD which are filtered to the red, green and
blue spectral wavelengths. A 32-bit microprocessor controls all functions in the AT-140GE
camera. The CCD sensor output is normalized in CDS and preamplifiers. The signals are then
digitized to 16 bits. Digital gain control, color matrix, look-up tables and setup can do signal
processing in 16 bits before the signal is converted to a 32- or 24-bit RGB pixel format via
GigE

Vision interface.
