MegaPlus®Model ES 4.0/E
1. INTRODUCTION
1.1 Introduction
With spatial resolution of four million pixels, and several different frame rates achieved through
binning, the Redlake MASD, Inc. MegaPlus Camera, Model ES 4.0/E, is designed for medical,
scientific, inspection, and machine vision applications. The compact camera package operates
through a digital connection to a host computer. The digital interface connector, located on the
camera’s rear panel, sends eight-bit digital output video to the computer and receives control
commands from the computer. This camera can be ordered with a twelve-bit digital video output
and/or a Camera Link interface as options.
Featuring an interline Charge Coupled Device (CCD) sensor array, the camera has
2048 (H) x 2048 (V) light sensitive elements (pixels). These pixels are 7.4 microns square with a
60% fill ratio. This MegaPlus camera model has individual gain and offset correction for each
pixel. Pixel by pixel gain and offset correction gives the camera a uniform flat field response at all
light levels.
The camera operates continuously or in one of three triggered modes. A minimum
programmable exposure time of 98 microseconds (98ms) is possible with the camera’s electronic
shutter. The frame rate is unaffected by the exposure time in continuous mode. The camera is
capable of binning and has dual output channels with data rates of 10, 20 or 40 MHz. In the
512 x 512 mode, the camera has a maximum frame rate of 60 fps. In the 1K x 1K binning mode,
the camera has a maximum frame rate of 30 fps. In the 2K x 2K binning mode, the camera has a
maximum frame rate of 15 fps at 40Mhz and 8 fps at 20Mhz. The camera requires a maximum of
24 watts at 24 volts DC and can be connected to commercially available frame grabber boards
capable of handling twelve bits of video data. Please note that some frame grabber boards may
not support the highest camera frame rates. Check with your frame grabber board manufacturer.

2.2.1 Digital Interface
The Digital Interface is available as a 68-pin, high density, dual row, D type connector or, as a
purchased option, a 26-pin, high-density Camera Link connector that connects the camera to a
frame grabber board and a serial communication interface for camera control. The frame grabber
board processes and displays video from the camera. A complete technical description of the
connectors and the signals that they carry is contained in Chapter 4 of this manual.
2.2.2 Trigger
The TRIGGER coaxial SMA type input connector on the rear panel of the camera accepts CMOS
TTL signals with a threshold of approximately 2.5 volts. The trigger pulse should have duration of
at least 100 nanoseconds and should be transmitted to the camera using a coaxial cable
terminated at the camera. The camera synchronizes to an external event using this input. The
operator can set the camera to respond to a positive or negative going trigger signal. See the
timing waveforms in Chapter 4 of this manual.
2.2.3 Strobe
The STROBE coaxial SMA type connector on the rear panel of the camera outputs a signal that
is TTL compatible and can drive a 50-ohm load. The strobe output pulse should be transmitted
through a coaxial cable with a terminating resistor at the receiving end. The leading edge of this
output signal can be used to fire a strobe light. The output signal polarity is user-definable. See
the timing waveforms in Chapter 4 of this manual.
2.2.4 DC Power Input
The DC power input is a two-pin connector. The power supply voltage must be 24 volts DC,
±4 volts DC, measured at the camera’s power connector. The current draw is a maximum of
1.0 amp with a typical draw of 0.8 amps.
WARNING!
Reversing the polarity of the DC voltage input or applying voltage levels in excess of 30
volts may permanently damage the camera. Pin 1 must be positive with respect to the
other pin. Pin 1 is nearest the RED DOT on the connector ring. See Figure 2-4.

3. CAMERA OPERATION
3.1 Introduction
The MegaPlus camera, Model ES 4.0/E, does not have any manual controls on the camera itself.
Camera operation is accomplished by commands sent to the camera through a serial data link
from a personal computer (PC). The camera serial data link may be either RS232 or RS422. In
either case, the command syntax is the same.
The commands in this chapter are in the order that you would use to setup a camera for the first
time. A list of the camera functions, commands and appropriate page numbers follows:
NOTE: The commands can be entered in either upper or lower case.
NOTE: These same commands and their argument ranges are alphabetized and
summarized on page 3-12.

3.2 Serial Interface Protocol
The camera uses a full duplex UART type asynchronous system, using standard nonreturn-to-
zero (NRZ) format (one start bit, eight data bits, one stop bit, no parity). The baud rate is fixed at
9600. The character code is ASCII standard.
The character flow control protocol is XON/XOFF. XON is assigned DC1 (control-Q) and XOFF
is assigned DC3 (control-S). The receiver sends the XOFF character when it wants the sender to
pause in sending data and an XON character when it wants the sender to resume.
91000116-001 Revision B 3-1 USER’S MANUAL

REDLAKE MASD, INC.
The camera will recognize a command as three command characters, followed by a space
character (or “?” in the case of a query), followed by an argument that consists of one or more
characters, ended by the carriage return and line feed characters. The camera responds to a
valid command with a carriage return and line feed (CR-LF).
3.3 Error Codes
The camera responds to an erroneous command or query by presenting the user with an error
code. The error codes and an explanation for each code are contained in Appendix A of this
manual.
3.4 Control Commands
NOTE: This section of the manual contains the commands and arguments in bold type. The
carriage return and line feed at the end of each command are not shown, as they are
required in every instance.
3.4.1 Readout Channels
Use this command to switch to single channel operation.
Suggestion: Set the camera frame rate to 8 fps (frames per second) using the FRS command
before changing the number of readout channels. Otherwise, the camera may change the frame
rate. See the valid frame rates versus readout channels listed on page 3.5 within the FRS
command description.
TYPE IN: RESPONSE EXPLANATION
RDM 1 CR-LF Sets the camera to single channel readout.
RDM 2 CR-LF Sets the camera to dual channel readout.
RDM? Queries the camera’s current readout.
RDM x Means the readout is set as indicated.
3.4.2 Mode Control
The MegaPlus camera operates in one of six modes: continuous, continuous fluoroscopy,
controlled, trigger, and double exposure. The mode of operation is selected by the MODE
command. The timing waveforms in Chapter Four may help you understand the different modes
of operation.
3.4.3 Continuous
The camera will take pictures at 15 fps in 2K x 2K binning mode, 30 fps in 1K x 1K binning mode,
and 60 fps in 512 x 512 mode. The camera can be synchronized to an external trigger source
through the TRIGGER input on the rear panel of the camera or the EXPOSE input of the digital
interface connector.
When multiple cameras are driven from the same trigger source, they will be synchronized to
each other within ±100 nanoseconds. The exposure time range is between 91 microseconds and
64.957 milliseconds in 2K x 2K binning mode. The exposure time range is between 92
microseconds and 32.451 microseconds in 1K x 1K binning mode. The exposure time range for
the 512 x 512 binning mode is approximately 98 microseconds to 16.2 milliseconds.
91000116-001 Revision B 3-2 10/15/02

MegaPlus®Model ES 4.0/E
3.4.4 Continuous Fluoroscopy
This mode is similar to the Continuous mode, except that the electronic shutter is not used. The
exposure time in continuous fluoroscopy mode is equal to the frame rate time. A frame rate of 30
fps means that the exposure time is 33.3 milliseconds. Since the exposure is fixed, the software
control of exposure is disabled in this mode.
3.4.5 Controlled
The start and exposure time of each image is controlled by input signals supplied by the user to
the EXPOSE input pins in the digital interface connector or the trigger input on the rear panel of
the camera. The exposure time is equal to the time the EXPOSE input signal is true. The frame
rate is inversely proportional to the exposure plus the readout time. The exposure time is
unlimited, but at room temperatures, dark field nonuniformities become noticeable with exposure
times greater than 100 milliseconds.
3.4.6 Trigger
Each exposure is started by a signal connected to the EXPOSE input pins of the digital interface
connector or the trigger input on the rear panel of the camera. The exposure command sets the
exposure time. An exposure starts 17 microseconds (± 100 nanoseconds) after the active edge
of the trigger pulse and ends at the exposure time selected by the EXE command. Use the TRM
command to select the positive or negative edge of the trigger pulse as the trigger point.
The EXPOSE input sets the start time for each frame of video. The camera will ignore additional
EXPOSE signals until it completes the current exposure. The trigger mode of operation is used
to capture a single image or a sequence of images.
3.4.7 Double Exposure
The double exposure sequence begins after receiving a trigger input through the digital connector
or the TRIGGER connector on the rear panel of the camera. The camera captures the first image
in the photo diode array, and then transfers this image to the CCD array. The first image is
transferred from the CCD to the internal frame store while the second image is being captured by
the photo diode array. The second image is then transferred into the CCD array and from there
to the internal frame store’s second image buffer.
When operating in Double Exposure mode, the maximum frame rate is approximately 11.4 fps
due to the necessity for 2 frames per trigger. The camera will ignore triggers that it cannot
accept; so more than 5.7 triggers per second will result in slower operation. If the trigger rate is
set lower, the camera will track the trigger rate exactly.

3.4.8 Mode
Use this command to set the camera mode of operation.
TYPE IN: RESPONSE EXPLANATION
MDE CS CR-LF Sets the mode to continuous.
MDE CD CR-LF Sets the mode to controlled.
MDE TR CR-LF Sets the mode to trigger.
MDE DE CR-LF Sets the mode to double exposure.
MDE CF CR-LF Sets the mode to continuous fluoroscopy.
MDE? Queries the current mode setting.
MDE xx Means the mode is set as indicated.
3.4.9 Binning Selection
Binning gives you the option of trading resolution for increased frame rate and better signal to
noise ratio. Binning is the process of grouping adjacent pixels electronically; thereby reducing the
time required to readout an image. This camera can group two adjacent pixels horizontally and
vertically giving one quarter the resolution but twice the frame rate with a better signal to noise
ratio.
TYPE IN: RESPONSE EXPLANATION
BNS 1 CR-LF No binning is performed; resolution is 2K x 2K pixels.
BNS 2 CR-LF 2 horizontal and 2 vertical pixels are binned together
producing an effective resolution of 1K x 1K pixels.
BNS 3 CR-LF 4 horizontal and 4 vertical pixels are binned together
producing an effective resolution of 512 x 512 pixels.
BNS? Queries the current binning selection.
BNS x Means the binning selection is set as indicated.
NOTE: Check the camera’s frame rate setting after changing the binning setting. Changing the
binning setting may cause the frame rate to change to the nearest valid setting.
3.4.10 Frame Rate Set
This command sets the camera’s frame rate dimensioned in frames per second (fps). Some
frame rates are only valid in specific combinations of readout channels, selected with the RDM
command, and binning modes, selected with the BNS command.
If you change the binning mode the camera will switch to the nearest valid frame rate.
NOTE: The FRS command sets the maximum frame rate limit in controlled and continuous
modes. FRS must be set to 15 in double exposure mode.

3.4.11 Exposure
This command sets the camera exposure time in increments of 0.063 milliseconds. In continuous
mode, the camera accepts exposure values from .091 to 64.957 milliseconds when BNS is set
to 1; and values between .092 and 32.451 milliseconds when BNS is set to 2. If the camera is
operating in triggered mode, the maximum exposure time becomes 112.298 milliseconds.
NOTE: The camera accepts and remembers a different exposure time for each of the three
binning modes. The camera switches to the stored exposure time when switching
binning modes.
TYPE IN: RESPONSE EXPLANATION
EXE xxxx CR-LF The argument range is from .091 to 112 to 298
milliseconds in increments of .063 milliseconds,
depending on the operating mode, the camera will
round up to the next valid setting for any exposure
value entered.
EXE? Queries the current exposure setting. The value
returned is the corrected value in milliseconds.
EXE xxxx Means the exposure is set, expressed in
milliseconds.
NOTE: After EXExxxx or EXE? Has been executed, type in “+” to increase the exposure time or
type in “-“ to decrease the exposure time by 0.063 milliseconds. The camera will respond
with the new value.
3.4.12 Trigger
This command selects the trigger source and polarity. There is two trigger inputs: the SMA
connector on the rear panel of the camera (labeled TRIGGER), and the EXPOSE input carried by
the digital interface connector. The camera will only respond to the selected source.
TYPE IN: RESPONSE EXPLANATION
TRS AIA CR-LF Selects the digital interface connector EXPOSE
signal as the trigger source.
TRS EXT CR-LF Selects the TRIGGER connector on the rear panel
as the trigger source.
TRS SW CR-LF Selects the TRE software commands as the trigger
source.
TRS? Queries the trigger source.

TRM P
(see *NOTE)
CR-LF A positive going edge at the AIA EXPOSE input
trigger connector will start an exposure.
TRM N
(See *NOTE)
CR-LF A negative going edge at the AIA EXPOSE input or
the trigger connector will start an exposure.
TRM? Queries the current EXPOSE polarity.
TRE 0 CR-LF Ends an exposure in controlled mode if TRS SW is
in effect.
TRE 1 CR-LF Starts an exposure in all modes if TRS SW is in
effect.
TRE? Queries current state of trigger command.
*NOTE: The commands TRM and TRP are interchangeable. TRP may be used in place of TRM.
3.4.13 Transfer Pulse Delay
This command only applies to the double exposure mode. Transfer pulse delay sets the
exposure time for the first image. The exposure time for the second image is 64.946 milliseconds
in 2K x 2K mode, and 32.495 milliseconds with binning set to 1K x 1K.
TYPE IN: RESPONSE EXPLANATION
TPD xxx CR-LF Sets the delay in increments of 0.2 microseconds.
The argument range is from 1 to 999 microseconds.
If TPD is set to zero, the EXE value controls the
first image exposure time permitting equal exposure
time for both images.
TPD? Queries the current transfer pulse delay time
setting.
TPD xxx Means the time is set as indicated.
NOTE: After TPD xxx or TPD? has been executed, type in “+” to increase the transfer pulse
delay time or type in “-“ to decrease the delay time. The camera will respond with the new
value.
Sample commands with arguments:
TPD 1.6 Sets the delay time to 1.6 microseconds.
TPD 0 The EXE value now sets the delay time.
TPD 999 Sets the delay time to 999 microseconds.
3.4.14 Transfer Pulse Width
The transfer pulse width is fixed at twelve microseconds, except in double exposure mode. This
command sets the duration of the transfer pulse when the camera is in double exposure mode.
The transfer pulse width is the time that the first image has to transfer from the photo diode array
to the CCD array. As the transfer pulse width becomes shorter, the charge transfer between the
arrays does not have time to be completed and image quality will suffer.
TYPE IN: RESPONSE EXPLANATION
TPW xx CR-LF Sets the delay in increments of one microsecond.
The argument range is from 1 to 10 microseconds.
The default value is 8.
TPW? Queries the current transfer pulse width setting.
TPW xx Means the pulse width is set as indicated.
