For details of each timing chart, see pages 13 to 20. Setting of the Normal Shutter Using the DIP switches on the rear panel Shutter OFF 1/125 1/250 1/500 1/1000 1/2000 1/4000 1/10000 (EIA) 1/8000 (CCIR) Flickerless* (EIA: 1/100 CCIR: 1/120) Setting of the External Trigger Shutter You can set the shutter speed with the DIP switches or using the trigger pulse width. To set the shutter speed with the trigger pulse width, see page 8. Using the DIP switches on the rear panel Mode 1 (Non-reset mode) 1/100 (EIA)* 1/120 (CCIR)* (Unit: second) * If you set the mode to flickerless, the positions of DIP switches 1 to 3 are optional. 1/125 1/250 1/500 Notes · The positions of DIP switches 6 and 7 are optional. · The DIP switch 5 position is optional. The images obtained when the normal continuous shutter or trigger shutter is used are field images (vertical resolution: 243 lines). Sample input timing chart EXT HD Continuous signal: 15. 734 kHz (XC-EU50) Allowable frequency value ±1%, 15. 625 kHz (XC-EU50CE) Allowable frequency value ±1% Using a strobe light and Restart/Reset mode, you can obtain bright frame images by synchronizing any strobe light. (Vertical resolution: 485 lines). EXT VD VD: 1/60 sec (XC-EU50), 1/50 sec (XC-EU50CE) Four or more VD pulses are required. Strobe light Exposure time for the Odd field Exposure time for the Even field Frame Accumulation (Factory setting) Video output Odd image Invalid image Even image Valid frame image Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside. Avoid lighting the scene during the light-emitting inhibit zone defined below. (The field is transfered to the storage area of the CCD, so it can be read out. ) Note For best performance, it is recommended that you not flash between VD and VD + 10 H (XC-EU50)/16 H (XC-EU50CE). 12 Mode Setting Timing Charts When set to Mode 1 For setting the shutter speed using the trigger pulse width HD/VD input N Continuous VD input Mode transition state External input External trigger inhibition area shutter operation (50 ms) 3 Exposure time (Te)*2 External trigger shutter operation 1 2 Exposure time (Te)*2 Normal operation*3 Trigger*1 Trigger pulse width* 3 Exposure time (Te)*2 External HD*1 External VD*1 (Continuous VD) EXT-VD Video out 1 2 *5 T: T=under 10 µs*4 T: T=under 10 µs*4 10 µs or more 3 WEN 250 H (EIA) 293 H (CCIR) TRG EXT-VD EXT-VD 65 µs 10 µs *1 This is a signal input from outside. Make sure to input both HD and VD signals. *2 Exposure time (Te) Te = Trigger pulse width + 97 µsec (EIA) Te = Trigger pulse width + 120 µsec (CCIR) (The effective trigger pulse width for the external trigger shutter operation is between 2 µs and 1/4 s. ) *3 The normal operation state is chosen when the trigger pulse width is 1/3 s or more. The trigger falling edge restores the external trigger shutter operation. In this case, the area between the falling edge of a trigger pulse and the subsequent 50 ms period is an external trigger input inhibition area. There is no guarantee of operation for any trigger input selected in this period. *4 If there is a falling edge on the external VD within a period of ­65 to +10 µs from the falling trigger edge (1 and 2 in the figure), it is not defined whether the image is output for the external VD falling edge or the image is output for the next external VD falling edge. (1 in the figure shows that the image is output for the next external VD. 2 shows the image for the external VD. ) In this case, see WEN since output of the image and WEN make up a pair. In any other cases, the image is output for the external VD falling edge after the trigger falling edge (3 in the figure). *5 When the external trigger shutter mode changes to the normal operation mode, one WEN signal is output. Note An image is not output correctly when the next trigger is input before the image for the previous trigger is output. 13 Mode Setting For setting the shutter speed using the trigger pulse width HD/VD input N Continuous HD input/Single VD input External trigger shutter operation 1 Normal operation*3 Mode transition state External input inhibition area External trigger shutter operation (50 ms) 2 Trigger*1 Exposure time (Te)*2 External HD*1 External VD*1 (Single VD) T: T=10 µs to 65 ms*4 Video out 1 Trigger pulse width* 3 Exposure time (Te)*2 min 10 µs 2 * 5 WEN 250 H (EIA) 293 H (CCIR) 250 H (EIA) 293 H (CCIR) 250 H (EIA) 293 H (CCIR) *1 This is a signal input from outside. Make sure to input both HD and VD signals in this case. Input the signal so that the VD phase aligns with the HD falling edge. *2 Exposure time (Te) Te = Trigger pulse width + 97 µsec (EIA) Te = Trigger pulse width + 120 µsec (CCIR) (The effective trigger pulse width for the external trigger shutter operation is between 2 µs and 1/4 s. ) *3 The normal operation state is chosen when the trigger pulse width is 1/3 s or more. (By entering a continuous VD in this section, an image is output. ) The trigger falling edge restores the external trigger shutter operation. In this case, the area between the falling edge of a trigger pulse and the subsequent 50 ms period is an external trigger input inhibition area. [. . . ] In this case, see WEN since the image and WEN make up a pair. (The internal VD falling edge and the beginning of the equivalent pause in the V period of the SYNC have the same phase. ) Note An image is not output correctly when the next trigger is input before the image for the previous trigger is output. 18 Mode Setting When set to Mode 2 For setting the shutter speed using the trigger pulse width External trigger shutter operation Normal operation*3 Mode transition state External input inhibition area External trigger (50 ms) shutter operation Trigger*1 Exposure time (Te)*2 Trigger pulse width*3 Exposure time (Te)*2 Video out 1 H to 2 H*4 WEN 250 H (EIA) 293 H (CCIR) 250 H (EIA) 293 H (CCIR) 250 H (EIA) 293 H (CCIR) *5 1 H to 2 H*4 *1 This is a signal input from outside. The trigger input frequency must be [Trigger pulse width + 1 field + 2 H frequency] or more. The operation is not guaranteed for shorter frequencies. [. . . ]
