3 opto-isolated auxiliary output signals (up to 24 V). Note that these
auxiliary output signals are sinking signals that share a common signal. If
one of these signals is used as a sourcing signal, the other two are no longer
available.
- One analog output . A 0-10 V signal designed to connect to the 0-10 V analog
intensity control pin of a light controller (such as, an Advanced Illumination
inline control system (ICS3), a Smart Vision Lights Brick light, or a similar
device). This signal does not provide power; instead, it provides analog intensity
(dimming) control (0-10 V translates to 0-100% illumination).
- Timers .1 exposure, 1 strobe, 8 general purpose.
❯
1 exposure timer. A 28-bit timer used to control the exposure of your Matrox
Iris GTX, and allows a range of exposure time from 50 usec to 4 sec. The
timer output will always set camera exposure, but can be simultaneously
redirected to any auxiliary output signal.
❯
1 strobe timer. A 28-bit timer whose output can be routed to any auxiliary
output signal. The resulting output signal can then be used to control a strobe
device. This timer is limited by the maximum possible value for the exposure
timer, and when the exposure timer ends, so will the strobe timer.
❯
8 general timers. Each of the timers (Timer 1 through 8) is a 32-bit timer
and can count up to 4,294,967,295 clock ticks before resetting. Each timer
can use a specified clock source for its active period and a different specified
clock source for its delay period.
- One I/O command list . Used to schedule I/O commands, in any order.
- One rotary decoder . Supports input from rotary encoders with quadrature
output.
