Page 5: Camera Operation
DuncanTech Camera Operation A functional diagram of DuncanTech’s DT4000 or DT4100 camera is shown in Figure 1 below. The camera utilizes a single CCD sensor to acquire the image. In color configurations, the sensor has gel filters placed over the individual pixels that filter the incoming light for red, green, and blue colors. - Page 6 The analog video output mode can be selected with a camera control command via the RS-232 port. Options for output format include NTSC or PAL interlaced video or progressive scan RGB at 640x480, 800x600, 1024x768, or 1280x1024. DT4000 User Manual - 9000-0005-04...

Page 23: Camera Control And Configuration Via Rs-232 Communications
DuncanTech Camera Control and Configuration via RS-232 Communications RS-232 Command Set Communication between the host and the camera takes place by way of the transmission of message packets from one to the other. Communication is always initiated by the host in the form of a host message packet (described below). -
Page 24: Echo Message Format
DuncanTech Checksum calculation: In order to calculate the check sum for any given command, accumulate the 8-bit sum off all bytes that constitute the command and it’s message bytes. Do NOT include the STX and “size of message” bytes in this sum. Having accumulated this sum, take the twos compliment of the sum. -
Page 25: Camera Command Set
DuncanTech Camera Command Set The following lists each command that is recognized by the camera, it’s parameters, structure, and expected echo. Definition of Channel Number Many of the commands that follow will refer to “Channel Number” as a parameter. The meaning and value of this parameter will vary depending on what model of camera you are working with. -
Page 26: Setchannelgain( Channelnumber, Gain )
DuncanTech SetChannelGain( ChannelNumber, Gain ) Sets the specified channel to the specified gain value where: ChannelNumber = 1, 2, or 3 Gain is a 16-bit value calculated as follows: For MS2100 and MS2150 Gain = 0 - 384 where the resulting gain value in dB is calculated as: gain = (.094)*DigitalNumber-4 dB For all other DuncanTech Cameras Gain = 95 –... -

Page 28: Setchanneloffset( Channelnumber, Offset )
DuncanTech SetChannelOffset( ChannelNumber, Offset ) Adds the specified offset to the specified channel. The offset value is in an 8 bit, straight binary format. [Note: DuncanTech’s Correrlated Double Sampling circuitry automatically removes any offset at the beginning of every line. Due to this advanced technology, it has been found that this particular command is not needed because image signal does not have an offset. -

Page 30: Setintegrationtime( Channelnumber, Integrationtime )
DuncanTech SetIntegrationTime( ChannelNumber, IntegrationTime ) Note: This command title adjusts the length of the time period during which the sensor gathers light for any given frame. In a conceptual sense, this is often thought of and referred to as “exposure” control. However, this terminology can be confusing. The specific parameter being adjusted is the integration time period for the sensor. - Page 31 DuncanTech Echo: Message Byte Contents $02 - STX $02 - LSB size $00 - MSB size $14 - command byte status $?? - checksum GetIntegrationTime( ChannelNumber Requests the camera to return the present integration time setting for the specified channel.
