OVERVIEW
The Bobcat HD-SDI series of cameras are highly programmable and flexible.
All of the cameras resources (internal registers, video amplifiers and parameter
FLASH) can be controlled by the user. The user communicates with the
camera using a simple, register-based, command protocol via the Camera’s
RS-232 serial interface. The interface is bi-directional with the user issuing
‘commands’ to the camera and the camera issuing ‘responses’ (either status or
info) to the user. The entire camera registers and resources can be configured
and monitored by the user. The camera’s parameters can be programmed using
the Bobcat Configurator graphical user interface.

CAMERA CONFIGURATION
4.2.1.
Configuration Memory – parameter FLASH
The camera has a built-in configuration memory divided into 4 segments:
‘work-space’, ‘factory-space’, ‘user-space #1’ and ‘user-space #2’. The ‘work-
space’ segment contains the current camera settings while the camera is
powered-up and operational. All camera registers are located in this space.
These registers can be programmed and retrieved via commands issued by the
user. The workspace is RAM based and upon power down all camera registers
are cleared. The ‘factory-space’ segment is ROM based, write protected and
contains the default camera settings. This space is available for read operations
only. The ‘user-space #1’ and ‘user-space #2’ are non-volatile, FLASH based
and used to store two user defined configurations. Upon power up, the camera
firmware loads the work-space registers from the factory-space, user-space #1
or user-space #2 as determined by a ‘boot control’ register located in the
configuration memory. The ‘boot control’ register can be programmed by the
user (refer to Camera Configuration Section). The user can, at any time,
instruct the camera to loads its workspace with the contents of the ‘factory-
space’, ‘user-space #1’ or ‘user-space #2’. Similarly, the user can instruct the
camera to save the current workspace settings into either the ‘user-space #1’ or
‘user-space #2’.
The non-volatile parameter FLASH memory also contains Defective Pixel
Map, Hot Pixel Map, Flat Field Correction Coefficients, LUT 1 and LUT 2,
which can be loaded to the camera internal memory upon enabling the
corresponding camera feature. The user can create its own DPM, HPM, FFCC,
and LUT tables and upload them to the parameter FLASH using the Bobcat
Configurator graphical user interface.
