Terminal Block
This section describes the pin out provided by the connection module consisting of:
Pin NO. 1 2 3 4 5 6
The input/output is used in applications for event triggering, time-lapse recording, alarm
notification via e-mail, picture storage to FTP locations.
- Input – For example, an infrared sensor that can be activated from Trigger on/off from
the live view page or as an action to an Event condition setting.
- Output – For example, an alarm device light that can be activated from the relay output
button on the live view page or as an action in the Event Trigger settings.
NO Function Description
1
Digital In (+) Input for the external input devices (+)
2
Digital In GND (-) Input for the external input devices (-)
3
Digital Out (+) Output to the external output devices (+)
4 Digital Out GND (-) Output to the external output devices (-)
5
RS-485 R/TX(+) Control signal pin for external keyboard controller(R/TX+)
6
RS-485 R/TX(-) Control signal pin for external keyboard controller(R/TX-)
1. Press the tap on the top of the pin (see the table above to determine which pin to use)
2. Push the cable into the connector and secure it by loosening the tap.
Digital Input – connect to GND to activate or leave floating (unconnected) to
deactivate.
Digital Ouput – Max. load 50 mA, max. voltage 24 V DC. An open-collector NPN
transistor with the emitter connected to pin 4 (GND). If used with an external relay,
a diode must be connected in parallel with the load for protection against any
voltage transients.
