Camera Features

TS-9720EN Series Progressive Scan Shutter Cameras

Note: Gain Value is Gain entry in camera LUT after calibration.

When the EN camera is controlled by a light sensor, user can monitor the gain value in the EN setup

software by accessing “Camera Gain” status register (Address = 232). This Gain value is the Gain Table

Entry in LUT after calibration (left side of the table above).

6.3.3 A/D Converter Parameter (Vtop and Vbottom)

Normally, Vtop and Vbottom are controlled automatically by an ADR algorithm inside the EN, based

on the output from the light sensor. While manual controls exist for changing Vtop and Vbottom, JAI

PULNiX does not recommend that users change the Vtop and Vbottom settings established by the ADR

algorithm. A great deal of knowledge is required to set these values correctly, and it is possible to set

these parameters so that the A-to-D circuit will not function correctly.

You can manually set Vtop and Vbottom by using the EN setup software (See Section 7.2 on page 47

for more information).

6.4 Flash/Nighttime Light Control

The strobe and continuous nighttime light controls are critical at nighttime. ADR (Automatic Dynamic

Range) control inside the EN automatically turns on and off the strobe and night light based on the

output from the light sensor. The user can manually turn on and off the strobe and night light if

necessary. You need to be able to access the following registers by means of the EN setup software.

The distance and angle of the strobe unit toward the target is critical and must be optimized. Please refer

to the VIS300 Installation Manual for more information.
