4: Operating the JAZ-PX Module

Menu Item Description
Intensity Controls the discharge voltage (and thus the flash intensity) of the lamp. Select
400-600V. On battery power, the intensity is restricted to 400V.
Number of Flashes Sets the number of times that the lamp should flash after detecting a trigger event.
Holdoff Time Specifies how long the timing generator should wait after detecting a trigger event
before beginning to flash at the rate specified by the Flash Rate parameter.
Timing Controls Controls used to set the timing behavior of the JAZ-PX module.
Force Trigger An emulated trigger signal that can be used to force trigger events on the JAZ-PX
module at any time. Forcing a trigger causes a trigger event with the same
behavior as if the device detected a stack trigger. Force Trigger will not have any
effect when the device is in Free Running mode, but it is not masked by turning
Trigger Enable off.
Timing Reset Does not reset the timing parameters themselves. Instead, it resets the state of the
counters keeping track of timing in the hardware. This can be useful to “escape”
from long flash periods or large values set in the Number of Flashes parameter.
Free Running Puts the device into Free Running mode. In this mode, the timing generator simply
flashes the lamp at the rate that is specified by the Flash Rate parameter and
ignores trigger events.
Run Forever When enabled, the timing generator will enter Run Forever mode. In this mode, it
will ignore the Number of Flashes parameter setting and continue flashing forever
once it has received a trigger event. It will re-sync to any trigger events that are
detected during that time.
Output Enable When disabled, the lamp will not flash. When set to 1, the lamp will flash as
normal.
Trigger Enable When enabled, the timing generator will not detect trigger events that are
generated by the stack trigger. It will still detect timing events that are generated by
the forced trigger.
Advanced Settings Provides the advanced capability to set parameters and controls directly on the
device, bypassing the Jaz menus. It also contains the power management menu.
Write Register Allows you to write values directly to the control registers of the JAZ-PX module.
Read Register Allows you to write values directly to the control registers of the JAZ-PX module.
Power Mode Sets the power mode of the JAZ-PX module to either battery power or external
power. You must manually set the power mode to external power to access
intensities greater than 0 (400V) and flash rates higher than 200 Hz (5 msec).
Using the JAZ-PX module on Jaz battery power at flash rates greater than 200 Hz
can result in unexpected behavior.
