6. Functions and Operations
6.1. Basic functions
The CM-141MCL and CB-141MCL cameras are progressive scan cameras with 12-, 10- or 8-bit
video output via a Mini Camera Link interface. The cameras have 2/3, 1/2, 1/4 or 1/8 partial
scanning or variable partial scanning for faster frame rates. Vertical binning mode is also
available on monochrome version.
The camera can operate in continuous mode as well as in 4 triggered modes:
- Edge Pre-select Trigger (EPS)
- Pulse Width Control Trigger (PWC)
- Reset Continuous Trigger (RCT)
- Smear less EPS Trigger (EPS)
Depending on the timing of the trigger input in relationship to FVAL (camera internal frame
valid clock), the start of exposure can be immediate (no-delay, LVAL asynchronous) or
delayed until next LVAL (LVAL synchronous).
In the following section the functions are described in detail.
6.1.1 Vertical Binning (CM-141MCL only)
The binning functions can be used to achieve higher frame rate or higher sensitivity. The
drawback is lower resolution.
Vertical binning is done by adding the charge from pixels in adjacent lines in the horizontal
CCD register. Fig.11 shows the vertical binning principle.

The CM-141MCL has ON or OFF function for Vertical Binning:
Setting Resolution Frame rate
Off (no binning) 1392(h) x 1040(v) pixels 30.12 frames/sec.
2:1 binning 1392(h) x 520(v) pixels 50.18 frames /sec.
