3.8.2 Signal Output Pins
When an event is detected, the MOBOTIX camera can switch the signal output
(pin 1). Use the corresponding options in
Setup Menu > Actions
to set how long
the camera should close the signal output.
•
Off
: Signal output is open (10 kOhms on 3.3 V)
•
1s, 2s, 5s, 10s, 30s, 1min, 5min
: Closes the contact between pin 1 of the D
Sub 15 HD connector and the ground (pin 5). The signal output is protected
against power surges and unwanted feedback (±48 V) and switches up to
50 mA. It can thus switch a 12 V relay with 0.6 W and a 24 V relay with 1.2 W.
Open
Setup Menu > Enhanced Signal Out Options
to set custom switching times
for any combination of events (not Web models). This dialog also allows using a
time table and setting a dead time.
Click on
Admin Menu > LED Setup
and set one or more LEDs to
Signal input to dis-
play the state of the input signal for testing (
Signal input option: loop closed = LED
on).

Activate the signal output
in
Admin Menu
> LED
Setup
or for specific
events in
Setup Menu
>
Event Settings
The event settings allow
activating the signal out-
put for a certain time only
(to generate an impulse)
Example setup
Select the trigger condi-
tion:
- Open (high)
- Closed (low)
- Rising (low to high)
- Falling (high to low)
- Change:
(rising or falling)
Besides detecting the
current state (open or
closed), you may also trig-
ger upon rising, falling or
changing signal flanks.
Notes
In contrast to the
signal output pins
of the RS232 interface (pins
3
and
7
), the
signal output pin 1
assumes an inactive state and will stay in-
active while the camera is booting.
The
Pin-out of MX Interface Connector D Sub 15 HD table in section
3.7.1,
MX Interface Connector for Direct Connections, contains a de-
tailed explanation of the individual pins.
