6. Functions and Operation
Apart from the standard continuous operation, the CV-M10 features two external asynchronous trigger modes, Edge Pre-
select and Pulse Width Control mode. These 2 external trigger modes can operate with either H reset or H non-reset. In Edge
Pre-select and H reset, the internal HD is reset on the falling edge of the trigger and the exposure starts. For Pulse Width
Control and H reset, the rising edge of the trigger will stop the exposure and reset the internal HD. In H non-reset, the
exposure will be synchronized to the internal HD. It will start on the first HD after the trigger negative going edge.

6-1. Input/Output of HD/VD Signal
6.1.1. Input of External HD/VD signals
This setting is factory pre-set. The video output is synchronized with external HD/VD signals if applied. If no ext. HD is
connected, the camera will switch to the internal X-tal controlled HD sync. If no ext. VD is connected, the camera will
continue with its internal VD.
The external HD/VD signal should be 4.0 Vp-p ±2.0V from a 75 ohm source. In case of TTL level input 2.0 to 5.0V the 75 ohm
termination can be removed by open JP3/JP6 on PK8189A board.

6.1.2. Output of Internal HD/VD signals
In order to output internal HD/VD signal 4.0Vp-p from a 75 ohm source, a jumper setting is required. JP1/JP4 on PK8189A
board is to be open, and JP5/JP7 are to be short.

6.2. Continuous operation
For application that do not require asynchronous external trigger, but run in continuous operation, this mode is used. SW1-
4 Trigger select on camera rear is set to ON for normal internal trigger mode. The shutter time or exposure time are selected
by SW1-1 to SW1-3 on camera rear (and SW1-1 to SW1-4 on PK8206 for BX versions). The setting can be done via RS 232C for
the RS versions.
The shutter time can be selected within the following range:

The shutter time can be selected within the following range:
Normal shutter
8 step. 1/50 to 1/10,000 sec. for CCIR. 1/60 to 1/10,000 sec. for EIA
High speed shutter
8 step. 1/25,000 to 1/917,000 sec for CCIR.
1/20,000 sec. to 1/800,000 sec. for EIA
Low speed shutter
8 step. 2 fields to 16 fields
for CCIR and EIA
