Introduction The KODAK MEGAPLUS Camera, Model ES 310, does not have any manual controls. Camera operation is accomplished by commands sent to the camera through a serial data link from a personal computer. In this chapter we will present the various operating modes of the camera with an explanation of the function followed by the command sequence that must be transmitted by the computer. The camera serial data link is configurable as RS232 or RS422/ RS485. The command syntax is the same in either case.
Serial Interface Protocol SERIAL COMMUNICATIONS 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 based on the ASCII standard. The character flow control protocol is XON/XOFF. XON is assigned DC1 (control-Q) and XOFF is assigned DC3 (control-S).
Serial Interface Protocol SETTING SERIAL COMMUNICATIONS MODE The camera can use either an RS232 or an RS422/RS485 connection for serial communication, but your host computer must have both RS232 and RS422/ RS485 communications capability to use this command. NOTE Type In: Response Explanation SCP 232 CR-LF Sets the camera serial port to respond to RS232 signals. SCP 422 SCP? CR-LF Sets the camera serial port to respond to RS422 signals. Queries the COM port setting.
Using RS485 Multi-Drop RS485 MULTI-DROP, ADDRESS SET This command is invalid when multi-drop mode is on (see below). Assign an address to a camera with this command and then execute a SAV command (page 3.15). The cameras address will default to zero when its power is turned off if you do not issue a save command after changing a cameras address. The address is used to send a camera commands when in RS485 multi-drop mode.
Using RS485 Multi-Drop Procedure 1. Switch each camera to RS422 operation using the procedure detailed on page 3.3 of this manual. 2. Give each camera a unique address using the ADR and SAV commands. Assign the camera that will be furthest away from the host computer an address of 99. When you are using multi-drop communications the camera furthest away from the host computer must have resistive terminators connected to the RS485 signal lines.
Selecting Video Output Options ANALOG VIDEO OUTPUT This command controls the analog video output on the rear panel of the camera. Type In: Response Explanation VID ON CR-LF Turns the analog video output on. VID OF CR-LF Turns the analog video output off. VID? Queries the analog video output status. VID x Indicates the current video output status.
Selecting Video Output Options BLOCK READOUT MODE You can choose a portion of the image to readout that is defined by the block start and block stop commands. The minimum block size is 17 rows. The block size changes the effective fame rate, smaller blocks take less time to read out. Block readout mode can be used along with alternate row readout for higher frame rates. Type In: Response Explanation BLK ON CR-LF Turns the block readout mode on. BLK OF CR-LF Turns the block readout mode off.
Selecting an Operating Mode MODE CONTROL The KODAK MEGAPLUS Camera operates in one of four modes, continuous, control, trigger, or retriggered. The mode of operation is selected by the mode command. Continuous The camera can take pictures at 15, 25, 30, 50, 60, and 85 frames per second (fps). The frame rate is set by the FRS command, The default frame rate is 30 fps. The exposure time range is from 94 microseconds to one divided by the frame rate.
Selecting an Operating Mode Retriggered Each exposure is started by a signal connected to the EXPOSE input pins of the AIA interface connector or the trigger input on the rear panel of the camera. The exposure command sets the exposure time. An exposure starts 20 microseconds (± 100 nanoseconds) after the active edge of the trigger pulse and ends after the exposure time set by the EXE command, unless another trigger is received. The active edge of the trigger pulse is selected using the TRM command.
Setting Exposure Time EXPOSURE This command sets the camera exposure time. Enter an exposure time value between 94 microseconds, and about (1/frame rate), in milliseconds, when you are in continuous mode. The maximum exposure time is 96 milliseconds in trigger and retrigger modes. The camera picks a valid exposure time closest to the value you entered. The exposure time setting is not valid in control mode. The exposure time range is affected by the alternate row and block mode settings.
Setting Exposure Time AUTO EXPOSE VIDEO LEVEL Sets the target video level for the auto expose function. Video level ranges from 0 at black to 127 for white. Type In: Response Explanation SET xxx CR-LF Sets the target video level to xxx with a range between 0 and 127. SET? Queries the camera for the current target video level. SET xxx Means that the target video level is set as indicated. AUTO EXPOSE VERTICAL ADDRESS Sets the vertical location of the top edge of the 256 rows high exposure window.
Setting Exposure Time AUTO EXPOSE HORIZONTAL ADDRESS Sets the horizontal location of the left hand edge of the 128 pixel wide exposure window. The default value of 255 puts the exposure window near the center of the image, left to right. Type In: Response Explanation AXX xxx CR-LF Sets the horizontal pixel address for the upper left corner of the exposure window. The default value is 255 and the range of values is from 1 to 517. AXX? Queries the camera for the current sample box horizontal location.
Selecting a Trigger Mode TRIGGER This command selects the trigger source and polarity. There are two trigger inputs, the SMA connector labeled Trigger, and the EXPOSE input carried by the AIA interface connector, on the rear panel of the camera. Type In: Response Explanation TRS AIA CR-LF Selects the AIA 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? Queries the trigger source.
Controlling Camera Black Level BLACK LEVEL The black level control functions much like the brightness control on a television set. The fixed video black level is set at the factory so that the output video is just above the black clipping level with the lens capped. The black level can be varied over a range of plus or minus 50 percent of peak white video. Type In: Response Explanation BKF CR-LF Sets the black level to an internal fixed value of approximately 10 counts above zero.
Setting Camera Gain DIGITAL GAIN Sets the camera gain to a factor of 1, 2 or 4. Type In: Response Explanation DGN 1 CR-LF Sets the camera gain to unity. DGN 2 DGN 4 CR-LF CR-LF Sets the camera gain to times two. Sets the camera gain to times four. DGN? Queries the current gain setting. DGN x Indicates that the gain is set to the factor value given. GAIN BALANCE The gain of the two output video channels are matched at the factory to minimize row to row shading.
Saving Camera Configurations RESTORE FACTORY SETTINGS Use this command to return the camera black level balance and gain balance settings to their original values as set by the factory. SAVE Type In: Response Explanation RFS CR-LF Restores the factory settings for black level balance and gain balance. Type In: Response Explanation SAV RESET Type In: RST 3.
Displaying a Test Pattern DISPLAY WEDGE Displays a linearly increasing gray scale that reaches peak white and then resets to black near the center of the picture, as shown below. This function is useful for aligning the camera image to a frame grabber. The display wedge defaults to off when the power to the camera is turned off. Type In: Response Explanation WDG ON CR-LF Means the wedge is being displayed. WDG OF CR-LF Means the camera is imaging. WDG? Queries the state of display wedge. 3.
Query Commands STATUS QUERY The status query command enables the user to get all the camera operating parameter information with a single command. Type In: Response STS? Response Explanation Gives complete camera status with one query. The following parameters are transmitted with a carriage return after each parameter: Definition Example GAB xxxx .. Shows the gain balance setting. ...................................GAB 36 BKB xxxx .. Shows the black level balance setting. ........................
