Pantera SA 2M30 - Frame Grabbers

Pantera SA DS -21-02M30 and DS-22-02M30 User’s Manual 22
3.8 Setting Frame Rate, Exposure Time, and
Exposure Mode
With five different exposure mode settings, the 2M30 delivers many possibilities for
flexible camera timing. Table 7 outlines each of these five exposure modes, and is
followed by a full explanation on how to set the camera’s frame rate and exposure time.

Mode SYNC Description
2 Internal Yes Yes (Factory setting) Internal SYNC ,
programmable frame time and exposure
time using commands ssf and set.
Note: The parameter being programmed
(i.e. Frame rate or Exposure time) will be the
driving factor so that when setting frame
rate, exposure time will change to
accommodate the new frame rate and visaversa.
3 External No No External SYNC, maximum exposure time
(no shuttering).
4 External No No “Smart EXSYNC” Mode: external exposure
time – high time of external signal is
exposure time and 1/period is frame rate.
6 External No Yes External SYNC, programmable exposure
time. NOTICE: The user is responsible for
not violating timing constraints for the
external sync signal used in this mode.
Overview: Setting Frame Time and Exposure Time
The camera’s frame rate (synchronization) can be generated internally through software
commands or input externally from a frame grabber/host system. To select how you
want the camera’s frame rate to be generated:
1. You must first set the camera mode using the sem command. Refer to section 3.8.1
Setting the Exposure Modes for details.
2. Then, when applicable, use the commands ssf (mode 2 only) to set the frame rate
and/or set (mode 2 or 6), to set the exposure time. Refer to Step Two on page 26 for
details.
