6M3P Camera User’s Manual ! 16 WARNING: Due to initialization sequencing after power-up, no commands should be sent to the camera for a minimum of 1 second after power up. 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.

6M3P Camera User’s Manual 21 3 &DPHUD 2SHUDWLRQ 3.1 How to Control the Camera The 6M3P’s RS-232-compatible serial interface allows you to control its configuration and operation, including: • Triggering Mode • Binning • Frame Rate (See also triggering) • Integration Time • Gain and Offset Command Protocol Overview The camera accepts 8-bit command/value pairs via its RJ-11 serial port using RS-232 compatible signals.
PAGE 22
6M3P Camera User’s Manual 22 &Rntrol 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.

A 6M3P will return a value of 33h when this command is issued.

Changing the shutter time involves writing to the three shutter time registers. 3.
PAGE 28
6M3P Camera User’s Manual 28 Free Running (Programmed Integration): This mode is the camera’s default. The camera speed is controlled by writing a 3-byte integration time value (in µs) to the three Integration Time registers. These three bytes are then combined to form a 24 bit integration time. The number represents the integer number of microseconds the camera will collect light. The number programmed in the three registers should not be below 10 PS (0000Ah).
PAGE 29
6M3P Camera User’s Manual 29 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. Integration begins within 200ns after the rising edge and stops when the programmed integration time has completed.
PAGE 30
6M3P Camera User’s Manual 30 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. 3.11 Controlling Frame Rate The 6M3P 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.

6M3P Camera User’s Manual 34 5 &OHDQLQJ DQG 0DLQWHQDQFH 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.
PAGE 35
6M3P 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.
