Input and Boot Field
The sixth field is an optional Input and Boot field that defines the input and boot trigger functions.
Using the trigger variables
boot, B, I1
and
I2
respectively, you can program the AXIS
2400/2401 to trigger at startup or on the logical states present on the Control button and digital
input ports. The
B, I1
and
I2
trigger variables must be proceeded by an activate condition,
/
,
\
,
0
or
1
, to indicate when the trigger variable is activated.
Note:
The AXIS 2400/2401 has four digital input ports 1 - 4 interfaced via the Terminal Block Connec-
tor. For connection details please refer to
Appendix F - The IO Terminal Block
.
The table below outlines the available trigger variables and their possible combinations:
Note:
The video server polls the input por ts every 0.2 seconds. Thus, more rapid logical transitions will
not be detected.
Complex triggering mechanisms can be developed by simply conjugating the trigger variables using
a logical AND function (&), as shown below.
Example 1
Activate on Control button transition from high to low and Input port 1 high.
Example 2
Activate on Input port 1 low and Input port 2 transition from low to high.
Trigger Variable
Description
BOOT
Activate at startup.
START
Activate at startup and when a new script is compiled
\V
Activate when one enabled video signal is lost
/V
Activate when all enabled video signals are back
\B
Activate after high-low logical transition of Control button.
/B
Activate after low-high logical transition of Control button.
1B
Activate when Control button is logically high (pressed).
0B
Activate when Control button is logically low (released).
\I1
Activate after high-low logical transition on Input Port 1.
/I2
Activate after low-high logical transition on Input Port 2.
1I1
Activate when Input Port 1 is logically high.
0I2
