Configuring the Video Server
22
Purpose
From the drop-down list, select the purpose of the port from the following alternatives:
• Pan Tilt - Select this if you wish to use a Pan Tilt Zoom device. An icon for PTZ appears below
the port icon. Click the PTZ icon and, from the drop-down list, choose from among the Pan Tilt
devices supported by the AXIS 2400+/2401+. See the Axis Web site at www.axis.com for a list
of currently supported devices.
• Modem - Select modem if you want to connect a V.90 compatible modem to your AXIS
2400+/2401+ (Port 2 only).
• AXIS 2191 Audio Module - This add-on device, supplied separately, provides your video
server with audio capability. For details on installing, configuring and using this device, please
see The AXIS 2191 Audio Module, on page 28. For use on Port 2 only.
Interface Mode (COM1)
From the drop-down list you can configure COM1 as either an RS-232 or an RS-485 port.
Selecting the former logically connects Serial Port 1 to the COM1 connector, whereas the
latter connects the port to the Terminal Block Connector.
Notes:
•Most CCTV equipment supports the RS-485 standard - a bi-directional, half-duplex standard for
transmitting data over multi-drop communication lines. Supporting up to 32 drivers and 32
receivers over a single twisted-pair cable, the maximum cable length should not exceed 4000
feet (1220 meters). Typically used for connecting a single PC to several addressable devices over
the same cable.
•Many Video cameras support RS-232, as it provides for reliable point-to-point communication
at low data transmission rates. Your wiring distances should be limited to 200 feet (60 meters)
for asynchronous data lines, and to about 50 feet (15 meters) on synchronous lines.
COM Settings
Using the drop-down lists for Baud Rate, Data Bits, Stop Bits and Parity; match the AXIS
2400+/2401+ data transmission formats with the devices connected to the COM1 and
COM2 ports. Select the default settings or make your own adjustments to suit.
Note:
Detailed communication settings for each supported Pan/Tilt device can be obtained from
www.axis.com. See also the documentation supplied with your Pan Tilt device.
