AXIS 210A/211A - The I/O Terminal Connector
The I/O Terminal Connector
Pinout and Interface
The 4-pin I/O terminal connector provides the interface to:
• 1 transistor output
• 1 digital input
• auxiliary power and GND
The terminal connector is used in applications for mo
tion detection, event triggering, time
lapse recording, alarm notification via e-mail, image storage to FTP locations, and so on.
• Input - for connecting a
push button for example. If the push button is pressed,
the state changes and the input becomes active (shown under Event Configura-
tion > Port Status).
• Output
- connects an alarm device that can be activated by Output buttons on the
Live View page, or by an Event Type. The output shows as active (Event Config-
uration > Port Status)
if the alarm device is activated.
Connect input/output devices to the ter
minal connector as follows:
1. Loosen the corresponding screw on top of the pin (see above for the correct
pin).
2. Push the cable into the connector and secure it by fastening the screw.
Pin Function Description
4 Transistor Output With a maximum load of 100mA and a max
imum voltage of 24V DC, this output
has an open-collector NPN transistor with the emitter connected to pin 1 (GND).
If used with an external relay, a diode must be connected in parallel with the load,
for protection against voltage transients.
3 Digital Input Connect to GND to activate, or leave flo
ating (or unconnected) to deactivate.
2 Auxiliary DC Power Input 7-20 VDC/max 5W. Electrically connected in pa
rallel with the PS-K power
connector, this pin provides an auxiliary connector for mains power to the unit. If
the unit is powered via this pin, a fuse should be used (rating: 1A Slow).
This pin can also be used to power auxiliar
y equipment, max 100mA, but note that
this is
not possible when the AXIS 210A/AXIS 211/211A is powered by PoE.
