You can power and control a strobe lamp with the dedicated strobe output signal
of your Matrox Iris GT. Note, to connect to a strobe lamp that has its own power
source, see the Connecting a powered strobe lamp to an auxiliary output signal
subsection of the Connecting external devices to auxiliary output signals section,
earlier in this appendix.
❖ Unlike the auxiliary output signals, the dedicated Matrox Iris GT strobe output
signal (STB_CCS_OUT0) sources the current for a strobe device. In addition, it
is a pulse-width modulated signal. Matrox Iris GT allows you to control the
amount of current (mA) that is transmitted when the signal is enabled (ON).
Matrox Iris GT can provide up to 500 mA of current.
Matrox Design Assistant allows you to specify a value for the intensity, which maps
to a value between 0 and 500 mA. For more information, refer to the IOReader
and IOWriter steps chapter in the Matrox Design Assistant User Guide. Refer to the
documentation that came with your strobe lamp to learn the recommended
amount of current to send.
Connect your Matrox Iris GT strobe output signal directly to the strobe lamp's
positive voltage (+V). The strobe lamp (ring LED) activates when the connected
Matrox Iris GT output signal is enabled (ON).
