C9100-13/-14 has 3 connectors for trigger input. C9100-23B only has 1 connector.

Trigger times property can control how many trigger camera tins out at synchronous readout trigger mode. The value ranges are different between C9100-13/-14 and C9100-23B.

Trigger delay property can control how long wait from input trigger timing to action by the thrigger. This property is not supported by C9100-13/-14, but supported by C9100-23B.

C9100-23B has built-in mechanical shutter. This is for protecting image sensor from "afterglow". So, the shutter may not be able to shield from strong light. And it is not recommend to open and close at every frame capturing in fast frame rate. In fast frame rate, it is recommended to open the shutter at starting experiment and close at ending. By the way, at factory setting, mechanical shutter control is not available. To make enable, please turn on DIP SW 2 in rear panel of the camera.

As default, C9100-13/-14 and C9100-23B cannot use shorter exposure than frame readout time in INTERNAL trigger mode. If host software changes DCAM_IDPROP_INTERNALTRIGGER_HANDLING, it is possible with compensation. DCAMPROP_INTERNALTRIGGER_HANDLING__SHORTEREXPOSURETIME can support shorter exposure time than framer readout time but frame rate becomes slower. In case of C9100-13/-14, frame interval also becomes inconstant. DCAMPROP_INTERNALTRIGGER_HANDLING__FASTERFRAMERATE can support faster frame rate but minimum exposure time is limited.

C9100-23B has capbility to use frame readout time always as exposure time. To do so, DCAM_IDPROP_EXPOSURETIME_CONTROL property has to be set DCAMPROP_EXPOSURETIME_CONTROL__OFF.

Exposure time range is different between C9100-13, -14 and -23B because of frame readout time. In case of INTERNAL trigger mode, the minimum exposure time is limited by frame readout time. In case of EXTERNAL EDGE / LEVEL and SOFTARE trigge rmode, exposure time can be shorter. If host software wants to use shorter exposure time than frame readout time in INTERNAL trigger mode, change value of DCAM_IDPROP_INTERNALTRIGGER_HANDLING.

C9100-13/-14 and C9100-23B support sensitivity in EM-CCD mode. The value of DCAM_IDPROP_SENSITIVITY can be 0 to 255. The value is not linear scale. If DCAM_IDPROP_DIRECTEMGAIN_MODE is DCAMPROP_MODE__ON, the value range becomes 4 to 1200 and the value is nearly amplifier ratio of sensitivity. The value is converted in DCAM from ratio to camera parameter, then DCAM sends it to camera.

C9100-23B can measure current sensitivity under certain condition. The following condition is necessary.

This measured value is always updated inside camera. For better measurement, we recommend to do following.

C9100-13/-14 supports contrast gain control in EM-CCD and Normal CCD mode. But in case of EM-CCD mode, sensitivity, which means EM-Gain, can improve S/N, but contrast gain is not. So C9100-23B supports contrast gain control in Normal CCD mode but not in EM-CCD.

C9100-23B has build in intensity lut. This is LUT conversion done in camera hardware. Threr are three related properties.

C9100-23B can return conversion factor under certain condition. By using conversion factor, host software can calculate electron number from intensity count of the image. The formula and properties are following.

By changing sensor readout speed, camera will run on faster frame rate mode or on high precision mode which is lower readout noise. In case of C9100-13/-14, EM-CCD mode has 3 readout speeds, and Normal CCD mode has 2 readout speeds. In case of C9100-23B, EM-CCD mode has 3 readout speeds, too, but speeds are different. And Normal CCD mode has only 1 readout speed.

C9100-13/-14 and C9100-23B support binning 1x1, 2x2 and 4x4 as standard. C9100-13/-14 also support binning 8x8 and 16x16 with M10354-01/-02 option. C9100-23B supports binning 8x8 and 16x16 with M10354-03 option.

C9100-23B has 3 connectors for output trigger.

Each output trigger can output different kind of timing.

Programmable output trigger will start by other timing. In case of C9100-13/-14, it can only start from starting EXPOSURE but in case of C9100-23B, it can also start from starting TRIGGER input.
