JAI CV-M536, CV-M539, CV-M538 operation manual EIA Non-interlaced / Field accumulation mode

CV-M536/538/539

 

To use this mode

Set:

SW1-4 to ON for ext. trigger shutter

 

SW1-5 to OFF for field accumulation

 

SW1-6 to ON for non-interlaced

 

SW1-1,2 and 3 to shutter speed

Input:

Ext. trigger to pin 5 on 6 pin multi connector.

 

Ext. HD to pin 6 on 12-pin multi connector. (If used).

 

75 Ohm termination is done with SW2-1 (HD) and SW2-2 (etc.trigger) on PK8057 board.

Refer to Timing Chart and Cautions below.

Detailed switch and jumper setting is described in “7. Mode Setting”.

For connections see “5. Pin Assignment”.

Cautions in the Edge Pre-select Mode.

1.Edge pre-select mode is effective only in non-interlaced, field accumulation mode.

2.The exposure start may delay up to 1H max., when the falling edge of ext. trigger pulse is not synchronized with the falling edge of ext. HD signal. To avoid this 1H delay and jitter, the falling edge of the trigger pulse should be synchronized with the HD pulse as shown below. It can be the ext. HD input or the Internal HD output.

3.The ext. trigger input is 75 Ohm terminated as factory setting. (R127 short and SW2-2 ON). The

voltage level of the ext. trigger has to be 4.0 Vp-p ± 2.0 V. The duration should be more than 1 H negative going. >64 µsec. and < 60 msec. The input is AC coupled.

4.If the ext. trigger input and ext. HD input are from a source with TTL level, set SW2-1 and SW2-2 OFF for non-terminated. SW2-1 for HD signal, SW2-2 for ext. trigger pulse. See “7.2 SW2 on PK8057 Board”.
