CV-M91 - 7 - 6. F unctions and Oper ations The different camera modes and functions can be set by switches and jumpers. Some functions like RGB setup and white clip can only be changed via RS-232C. Function names within “ “ are names used in camera control tool.
CV-M91 - 8 - 6.1.2. Internal sync out/WEN out On pin #7 on 9 pin sub-D connector, the factory setti ng is the internal composite sync signal o ut. By jumper settings it can be changed to WEN out. Refer to “7. Configuring the Camera.” To use this mode: Set function on PK8407: JP303 o, JP304 s for sync output.
CV-M91 - 9 - 6.2. Trigger Modes This camera can operate in 5 prima ry modes. 1 non-triggered, 3 externa l H synchronous trigger modes and 1 long time integration mode. 1. Normal continuous Mode . Pre-selected exposure. 2. Edge Pre-select Mode. Pre-selected exposure.
CV-M91 - 10 - 6.2.1. Continuous Operation (Non triggered) Trigger Mode Normal. It is for applications whe re the camera is continuous running without external trigger. The shutter will work in all 8 steps up to 1 /10,000 second. Refer to “7. Configuring the Came ra.

CV-M91 - 13 - 6.2.2. Edge Pr e-select Mode The exposure will start at the first HD after th e trigger leading edge, and it stops after the selected shutter time, and the resulting video is read out. An EEN pulse indicate the accumulation time, and a WEN pulse that the resulting video read out.
CV-M91 - 14 - 6.2.3. Pulse Width Co ntrol Mode The exposure will start at the first HD after th e trigger leading edge, and it stops between the first and second HD after the trigger trailing edge. An EEN pulse indicate the accumulation time, and a WEN pulse indicates that the resulting video is read out.
CV-M91 - 15 - 6.2.4. Start Stop Mode The exposure time is controlled by the interval between the ext. trigger and the ext. VD signal. The exposure starts at the first HD pulse after t he falling edge of the ext. trigger, and stops 14.5 H after the falling edge of the VD pulse.
CV-M91 - 16 - 6.2.5. Long time integration The exposure time is the interval between 2 ext. VD pulses sent to the VD input. (Pin No. 7 of the 12-pin connector). The exposure starts after in put of the first ext. VD pulse, and ends after the next input of the next ext.
CV-M91 - 17 - 6.3. Other Functions. Refer to “7. Configuring the Camera .” Scanning: SW1-5 on rear selects interlaced or non-interlaced. Non -interlaced PAL = 312H in EVEN field. Non-interlaced NTSC = 262 H in ODD field. Gamma: SW1-6 on rear for gamma select.
