1M60 Camera User’s Manual 13 Figure 3. 25 Pin Serial Port Connector to Camera RJ-11 Connector Figure 4. 9 Pin Serial Port Connector to Camera RJ-11 Connector Serial Communication Settings The serial interface operates at RS-232 levels with fixed parameters of 9600 baud, 1 start bit, 8 data bits, 1 stop bit, and no parity. The interface uses only three wires, for received data, transmitted data, and ground. In general writing data must start with a write command byte and be followed by a data byte.
1M60 Camera User’s Manual 14 The remote interface connector, on the cameras rear panel, is specified as a low-profile RJ-11 modular connector. The connector is a 6-position model, but only the center four positions are populated with contacts. It will mate with either the 4-position or 6position cable plugs. This type of connector typically requires special assembly tools; complete cable assemblies are available from suppliers such as Digi-Key: Serial Cable Source Digi-Key 701 Brooks Ave.
1M60 Camera User’s Manual 15 2.9 Timing Programmed Integration The 1M60 pixel clock runs at 20 MHz, so each pixel clock cycle will be 1/20,000,000 or 50 ns. The following diagram and tables describe the correct timing requirements for the 1M60 camera. Figure 6. 1M60 Timing VSYNC HSYNC A Data B D C 1 2 3 F E C PIXEL CLOCK “A” “B” “C” “D” “E” “F” represents the number of falling clock edges from the rising edge of VSYNC to the rising edge of HSYNC.
1M60 Camera User’s Manual 16 CHAPTER 3 3.0 Camera Operation 3.1 How to Control the Camera The 1M60’s RS-232-compatible serial interface allows you to control its configuration and operation, including: Triggering Mode Binning Integration Time Gain Offset Command Protocol Overview The camera accepts 8-bit command/value pairs via its RJ11 serial port using RS-232 compatible signals. Camera commands are “clock” commands which apply to the electronics that drive the image sensor.
1M60 Camera User’s Manual 17 3.2 Control Register Reference A number of functions and modes depend on the control register settings. These settings are detailed in the following sections. The “Write Control Register” command is used to write a register that controls specific camera triggering and test functions. This command must be followed by a data byte with bits defined as shown in the following table.
1M60 Camera User’s Manual 18 3.3 Reading the Camera Type This read command returns an 8-bit value unique to the type of camera interrogated. A 1M60 will return a value of 02h when this command is issued. This is useful for applications that need to function with multiple DALSTAR camera types. Example: Read the camera type Binary Hex Command 1100 0011 C3h Value Returned (1M60) 0000 0010 02h 3.
1M60 Camera User’s Manual 19 3.6 Adjusting Gain Bit [6] of register 1 is the Video Gain control bit. When this bit=0 the video channel gain=1x. When this bit =1, the video channel gain=4x. Example Use this command to set the gain to 4x: Command Value Binary 1000 0010 *1** **** Hex 82h **h Note: The register containing the Gain bit also controls other configuration data. All bits must be set appropriately. Note: At any gain setting, the CCD imager is still subject to blooming when it is over illuminated.
1M60 Camera User’s Manual 20 Example: 2x2 Binning More charge = brighter pixel q3 q1 q4 q1 + q2 + q3 + q4 q2 2 a a Normal image Binned image 1 Charge in Charge binned: 4 adjacent pixels 1 pixel output The 1M60 is capable of 2x2 binning. Bit [4] of register 1 is the Binning control bit. When this bit=0 the camera is in standard 1x1 mode. When this bit = 1, the camera will operate with 2x2 binning.
1M60 Camera User’s Manual 21 PIXEL OFFSET EXAMPLES. Programmed Offset Decimal/2’s Complement Register 3 88 (058h) -96 (FA0h – 2’s compliment) 152 (098h) -2040 (808h) X8h X0h X8h X8h Register 2 05h FAh 09h 80h Resulting Pixel Offset 55 (37h) -60 (-FC4h) 95 (5Fh) -1275 (-4FBh) The read user offset commands allow the user to read back this information from the camera.
1M60 Camera User’s Manual 22 WARNING: Do not set integration time higher than the limits of the equation above. Unpredictable operation may result Table 14.

1M60 Camera User’s Manual 24 Because this signal is internally OR’ed with the Serial Trigger input, care must be taken to ensure the serial bit [7] of register 3 is equal to a logic 0 while in SMA Trigger mode. Programmed Integration/Serial Trigger For external serial controlled triggering with a programmed integration time, a TTL rising edge on bit [7] of serial register 3 triggers the camera to acquire one frame of data.
1M60 Camera User’s Manual 25 Because this signal is internally OR’ed with the TRIGGER IN Sync input, care must be taken to ensure the TRIGGER IN signal is equal to a logic 0 while in Serial Trigger mode. 3.12 Controlling Frame Rate The 1M60 allows you to control frame rate in three ways. Free Running (Programmed Frame Rate): (default) The camera free runs with the internally programmed frame rate time and integration time.

1M60 Camera User’s Manual 28 CHAPTER 5.0 5.0 Cleaning and Maintenance 5.1 Cleaning Electrostatic Discharge and the CCD Sensor Charge-coupled device (CCD) image sensors are metal oxide semiconductor (MOS) devices and are susceptible to damage from electrostatic discharge (ESD). Although many sensor pins have ESD protection circuitry, the ESD protection circuitry in CCDs is typically not as effective as those found in standard CMOS circuits.
1M60 Camera User’s Manual 29 Protecting Against Dust, Oil, and Scratches The CCD window is part of the optical path and should be handled like other optical components, with extreme care. Dust can obscure pixels, producing dark patches on the sensor response. Dust is most visible when the illumination is collimated. The dark patches shift position as the angle of illumination changes.
1M60 Camera User’s Manual 30 CHAPTER 6.0 6.0 Troubleshooting START NO Verify the DC power supply and cabling are correct by checking voltages at the camera end of the power cable. WARNING – Power down the camera before disconnecting the cables! NO The camera did not pass the Power on Self Test. Power down the camera and verify the Serial Port and Data Port cables are as specified in section 2.5 & 2.6. Power the camera back up.
