4M30 Camera User’s Manual The camera uses an RJ-11 telephone-style connector for serial communications, with four conductors installed in a sixposition connector. Note that both four- and six- conductor plugs may be used interchangeably with the RJ-11 jack. IMPORTANT: Both the PC/AT and the camera are configured as “DTE” (Data Terminal Equipment) devices requiring the TXD and RXD lines to be swapped when interconnecting the two (note that pin 4, normally the yellow wire, is not used on the RJ-11.
4M30 Camera User’s Manual 15 Serial Communication Settings Table 9: Serial Port Configuration Serial Port Configuration Baud 9600, fixed Start bits 1 Data bits 8 Stop bits 1 Parity None 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.
4M30 Camera User’s Manual 16 Figure 6: Trigger Timing Description 2.8 Integration Time The minimum integration time (or shutter time) is 10 Ps. As with any full frame imager, the camera will continue to integrate during read out unless externally shuttered or strobed. 2.9 Timing The 4M30 pixel clock runs at 40 MHz, so each pixel clock cycle will be 1/40,000,000 or 25ns. The following diagram and tables describe the correct timing requirements for the 4M30 camera.

All bits must be set appropriately. 3.13 Triggering, Integration, and Frame Rate Overview Image capture triggering, integration, and frame rate are closely related. • Integration time can be less than 1/frame rate, but it can never be greater than 1/frame rate.
4M30 Camera User’s Manual • 27 External Integration/Serial Trigger: The camera will integrate as long as the Serial Trigger signal is held high. The integration time is effectively the input pulse width. In this mode, the serial signal also controls the frame rate. Due to variation in the host operating system, this mode is generally used only for camera setup and functional testing. The register settings required for each mode are defined in Table 17: Integration/Trigger Modes.

4M30 Camera User’s Manual 29 new External Trigger signal to trigger a new frame acquisition. The camera is “armed” when the read out of the acquired frame is completed. No additional rising edges, or triggers, should be allowed during the image acquisition or frame read out. This means in this mode TRIGGER IN necessarily controls both integration and frame rate.
4M30 Camera User’s Manual 30 Free Running Frame Rate can only be controlled by setting integration time. To specify programmed frame rate (by using integration time): 1. Set bit [7] of the Control Register to 0 (Integrate Mode = Internal), and bit [3] of the Control Register to 0 (Trigger Mode = Internal). To determine the integration time needed for a specific frame rate use the following equation: Integration Time = (1/Frame rate) - 32.35ms 2.
4M30 Camera User’s Manual 4. 31 Each TTL rising edge on the SMA connector or serial bit [0] of the Control Register will initiate a new frame of data, using the programmed integration time. To achieve 2.5 fps, a TTL pulse must be sent to the camera every 400 ms (1/2.5). External Integration This is the same as the External Integration/SMA Trigger Mode or the External Integration/Serial Trigger Mode. Refer to section 3.14 Controlling Integration Mode.

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.
4M30 Camera User’s Manual 35 6. Ground all tools and mechanical components that come in contact with the CCD. 7. DALSA recommends that CCDs be handled under ionized air to prevent static charge buildup. 8. Always store the devises in conductive foam. Alternatively, clamps can be used to short all the CCD pins together before storing. The above ESD precautions need to be followed at all times, even when there is no evidence of CCD damage.

4M30 Camera User’s Manual 39 $SSHQGL[ $ /9'6 (,$ 5HIHUHQFH EIA-644 is an electrical specification for the transmission of digital data. The standard is available from the EIA (Electronic Industries Association). It defines voltage levels, expected transmission speeds over various cable lengths, common mode voltage operating requirements for transmitters and receivers, and input impedances and sensitivities for receivers. The standard requires that two wires (e.g.
4M30 Camera User’s Manual 40 Figure 9. EIA-644 Example Unused EIA-644 Inputs and Outputs Unused outputs should be left unconnected. This will reduce power dissipation within the camera and reduce radiated emissions. Unused inputs should also be left unconnected; EIA-644 chips have fail-safe features that guarantee a known logic state (HIGH) in fault conditions (unconnected, shorted, or unterminated). Do not connect cables to unused inputs. Cables can act as antennae and cause erratic camera behavior.
