IO Ports
This page allows configuration of the two inputs and one output supported by the AXIS
230. Ports can be given descriptive names, and their Normal state can be configured.
The normal state describes the inactive state for the port. It is also an indication of the
function of the connected equipment and how it is activated. For example, if the activation
circuit in a door switch connected to an input is normally closed, this means that as long
as the door is closed then the state is also closed (inactive). When the door is opened the
door sensor will be active and the input will no longer be in its normal state. This is how
events based on external equipment are triggered.
Thus, in the I/O port list, if the Normal state for an input is set as Open, but the Current
state is shown as Closed, then the port has been activated, and vice versa.
Important!
COM Ports RS-232/RS-485
The COM1 port on the AXIS 230 is accessed via the terminal block (RS-485), and COM2 is
via the 9-pin D-SUB serial connector. Both are found on the rear of the unit. Select the
port from the links in the main menu.
Devices (Pan/Tilt devices, etc.) connected to the COM-ports on the AXIS 230 can be
controlled via Generic TCP/IP or Generic HTTP, or in the case of Pan/Tilt devices, by a
specific driver for the unit being used. Settings are managed and configured directly from
the user interface.
Select the port to configure and then choose the Usage for the port, whereupon the
relevant settings will be displayed. To make device-specific settings for a Pan/Tilt device,
click the Modify button.
For detailed listings of all of the available settings for each mode, the supported Pan/Tilt
devices, as well as more information about the different interface modes and pinout info,
please the online help, available from the setup pages. See also Unit Connections, on page
49.
Please note that some external devices may behave incorrectly in the event of an error
condition, e.g. a power cut.
