[. . . ] AXIS 242S IV Video Server User's Manual 2 About This Document This manual is intended for administrators and users of the AXIS 242S IV Video Server, with firmware release 4. 30. The manual includes instructions for using and managing the Video Server on your network. Previous experience of networking will be of use when installing and using this product. Some knowledge of UNIX or Linux-based systems would also be beneficial, for developing shell scripts and applications. [. . . ] If a script does cause problems, reset the unit to its factory default settings. A backup file may be of use to return the unit to its latest configuration). Axis strongly recommends that you do not use this function unless you fully understand the consequences. Note that Axis support does not provide assistance for problems with customized scripts. For more information, please visit the Developer pages at www. axis. com/developer Plain Config - this function is for the advanced user with experience of Axis video server configuration. All parameters can be set and modified from this page, including the audio encoding format. Help is available from the standard help pages. 48 AXIS 242S IV - System options Resetting to the factory default settings To reset the AXIS 242S IV to the original default settings, go to the System Options > Maintenance web page (described in Maintenance, on page 46) or use the control button on the front panel, as described below. Note that although a loaded IV module is always saved during a reset to the factory default settings, all of its values will be returned to their default settings. Status Indicator Control Button Using the Control Button Follow the instructions below to reset the AXIS 242S IV to the factory default settings using the Control Button. Keep the Control button pressed until the Status Indicator displays yellow (this may take up to 15 seconds). When the Status Indicator changes to Green (which may take up to 1 minute), the process is complete and the AXIS 242S IV will have been reset. Reinstall the AXIS 242S IV, as described in the Installation Guide. AXIS 242S IV - Unit connectors 49 Unit connectors The following connectors are described in this section: · · · · The D-Sub connector, on page 49 The I/O terminal connector, on page 50 COM ports RS-232 and RS-485, on page 51 The S-Video connector, on page 51 The D-Sub connector The AXIS 242S IV provides one 9-pin D-Sub connector, providing the physical interface for an RS-232 port, used for connecting accessory equipment; such as standalone PTZ devices for the remote control of connected video cameras.

The output will show as active (in Event Configuration > Port Status), if the device is activated. Pin 1 Function Auxiliary DC Power Input Description 7-20 VDC/min 8W. Electrically connected in parallel with the power connector, this provides an auxiliary connection for mains power to the unit. This pin can also be used to power auxiliary equipment, 9vDC max 100mA. Connect to GND to activate or leave floating (or unconnected) to deactivate. 2 3 4 5 6 7 8 9 10 11 12 GND Digital Input 1 Digital Input 2 Digital Input 3 Digital Input 4 Transistor Output Transistor Output Transistor Output Transistor Output RS-485 - A (non-inverting) RS-485 - B (inverting) With a maximum load of 100mA and maximum voltage of 24V DC, this output has an open-collector NPN transistor with the emitter connected to pin 2 (GND). If it is to be used with an external relay, a diode must be connected in parallel with the load for protection against any voltage transients. A half-duplex RS-485 interface for controlling auxiliary equipment, e g. PTZ devices. The AXIS 242S IV includes one (green) 12-pin connector block. [. . . ] Video management software - Video management software supplies the means for monitoring, analyzing and recording network video. In its simplest form, it offers live viewing, storage and retrieval of video sequences. Advanced applications may also provide support for recording of live video from multiple devices, different recording modes, search functions, remote access via a web browser, control of PTZ devices, etc. VMD (Video Motion Detection) - Video Motion detection defines activity (motion) in a monitored scene by analyzing image data and differences in series of images.
