RM-67X Series
3.2.2.2
Edge Pre-select Mode
The falling edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by the pre-
defined shutter speed set by RS-232C. (see section 8.3.63)
The leading edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by the pre-
defined shutter speed set by RS-232C.
The resulting video is output as “odd field” for CCIR, and appears 9H (CCIR) after the leading edge of WEN.
To use this mode:
Input:
Ext. trigger to pin 12 on 15 pin connector. Shutter exposure time determined by line
time from 1 (64μs) to 260 lines.
Set MFI mode: “Trigger mode”
Set MFI Termination: “Hi Z”
Set Trigger mode: “Edge Pre-select”
Set Vertical mode: “Field”
Shutter Control: “On”
Shutter Speed: SH=1 through 260 User selectable

Edge pre-select CCIR
Note: • The duration of the external trigger pulse must be greater than 1H. It is recommended to make this
longer, typically 9H.
3.2.2.3
Pulse Width Control Mode
The falling edge of the trigger pulse initiates the exposure. The exposure time (accumulation time) is governed by duration
of the trigger pulse.
The exposure time range is 1.5H to 1000H (shortest and longest pulse duration).
The resulting video is output as “odd field” for CCIR and appears 9H (CCIR) after the leading edge of WEN.
To use this mode:
Input:
Ext. trigger to pin 14 on 15 pin connector.
Set MFI mode: “Trigger mode”
Set MFI Termination: “Hi Z”
Set Trigger mode: “Pulse Width Control”
Set Vertical mode: “Field”
