AXIS 200+ and 240 User’s Guide Using the Camera Server

Input and Boot Field
The sixth field is an optional Input and Boot field that defines the input and boot trigger functions.
You can program the AXIS 200+ and 240 to trigger at startup or on the logical states present on the
Control button and digital input ports, using the trigger variables
boot, B, I1
and
I2
respectively. 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 240 has input ports 1 - 4.
The table below outlines the available trigger variables and their possible combinations:
Note:
The camera server polls the input ports every 0.2 seconds. Thus, more rapid logical transitions
will not be detected.
By conjugating the trigger variables using a logical AND function (&), you can develop complex
triggering mechanisms.
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.
\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 Activate when Input Port 2 is logically low.
... etc.
