[Setup procedure]
● Set FR(15) and FR(14) as follows rewriting FR (Flag register) with serial communication software.
AGCE=FR(15)
AEC function
(Note) "AGCE" (Auto Gain Control Enable) needs to be set to "0"
● Adjust the AGC set value (Reference level) to get necessary luminance level.
When the gain is insufficient, adjust the MGC set value a bit higher.
(Note) MGC set value is applied as the gain value of preamplifier on the stage prior to A/D converter.
S/N ratio of output signal degrades by setting MGC set value higher.
[Explanation] FR (15,14) setting and its operational mode
Correspondence relation of the content of each flag register FR(15),FR(14) and its operational mode is as follows.

(4-8) Test pattern display function (Black and white data output)
When initially connecting this camera to an image capture board, the
use of the test pattern display function of the equipment makes it easier to
confirm that the output timing of the camera and the details of the signal
connection match the particulars of the capture board.
When the test pattern function is set to be ON, the image sensor outputs the
test pattern in place of pictures as shown on the right.
As for this pattern, a numerical value of 4 is simply added in an incremental
manner for every horizontal pixel, and a saw-tooth profile is shown in the range
from the numerical value of 0 to 1020.(When set at 10 bit output) (Lower part
of the right figure)
(Note) FS5000GE usually outputs RGB signals of Bayer arrangement CCD,
however output signal gets black and white data when using this
test pattern display function..
(Note) In terms of upper 8 bits in 10 bit data, this 8 bits data corresponds to the
data in which a numerical value of 1 is incrementally added for every
horizontal pixel in the range of 0 to 255.
The lower 2 bits in 10 bit data are fixed to 0.
Therefore, it is 0 to 1020 (only the lowermost bit and next bit are
0 ) in the 10 bit data range, and 0 to 4080 for the
case of 12 bit output.
(Note) The value does not start with 0 at the edge of the effective image area.
(Note) The output values of the test pattern are not affected by the values of the gain setting or offset setting of the
camera.
The default setting is OFF. This setting can be changed by way of rewriting the configuration register with serial
communication commands.
(4-9) Monitoring function for internal temperature of camera
This camera is equipped with an internal temperature sensor to monitor the temperature inside the body. This function
makes it possible to use the camera in a safer way even in a harsh environment in terms of temperature, for example use
in the open air. With the use of serial communication commands, this function also works to control the forced air-cooling
fan of the camera and peripheral devices and others.
● How to monitor internal temperature of camera
The following two methods are available for monitoring the internal temperature of the camera:
● Turn on the MENU display and confirm on the OSD over the image. (Temperature to be displayed in Celsius)
● Confirm with temperature data to be returned in response to the serial communication command ("RTMP"
command). (Numerical conversion required separately)
