Installation and Configuration
3.1 Overview
The 2480 must e installed and configured for operation efore
use. Basic configuration encompasses network settings and
video attri utes such as frame rate and size.
After the asic configuration is complete, runtime settings may
e changed as needed. For example, OSD captions, streaming,
and output mapping of the crosspoint video switch may e
changed on the fly as required.
3.2 Installation
The module can e mounted in a standard 19-inch rack
enclosure or left unmounted. In either case, it is important to
ensure that the unit has adequate ventilation and cooling.
Ca les should e connected to the module after it has een
mounted. All ca le connectors are located on the module’s
ack panel:
•Power is rought into the unit’s IEC power receptacle from a
120VAC source.
•thernet. Connect a Cat-6 Ethernet patch ca le from the
unit’s RJ-45 jack to your LAN. The other end of the ca le
can connect to a switch or hu via a standard patch ca le, or
directly to a client (e.g., a PC) via a crossover ca le.
•Video. Connect video inputs and outputs to the module’s
BNC connectors as required. Unused video inputs and
outputs may e left unconnected.
3.3 Starting the System
Turn on the power switch on the ack panel and wait for the
module to oot. This takes approximately 30 seconds. The unit
can e pinged, if desired, to test its online status.
Configuration settings are retained when the 2480 is powered
down. When the module is powered up, it will restore the
retained settings and egin operating with those settings in
effect. When powered up for the first time, the 2480 will
restore factory programmed settings.
3.4 Network Configuration
The module’s HTTP server ecomes active when the unit
finishes ooting. Once the server is online, the module can e
configured through its internal we site from a remote we
rowser.
As shipped from the factory, the module’s IP address is set to
10.135.24.80
with netmask
255.0.0.0
.
If the default address is reacha le from the we client, the
2480’s we site can e accessed through its default URL,
http://10.135.24.80/
, and configuration and control can
e managed through the we interface. If the default IP address
is not reacha le, however, there are two ways to access the
unit:
• Reconfigure the client’s network settings so that it resides on
the same su net as the 2480. This method can e used only if
the 2480’s network settings are known and if the user is
authorized to change the client’s network settings.
• Create a plaintext configuration file named
cfg2480.txt
.
Edit the file so that it contains the desired 2480 network
settings as three lines of text, in this order: IP address,
netmask, and gateway address. Copy the file onto a USB
mass storage device. After the module has ooted, insert the
device into the 2480’s front panel USB socket. In response,
the 2480 will read the configuration file and configure its
network setting as specified in the file. Successful
configuration will e indicated y two audi le eeps. This
method can e used to configure the 2480’s network
interface even if its current network settings are not known.
After the we client has successfully connected to the 2480’s
we site, the module’s network settings can e changed through
its we interface. Note that your rowser may lose its
connection to the we server when the unit’s IP address or
other network settings are changed, thus making it necessary to
enter a new rowser URL in order to resume communication
with the module.
3.5 Setting Date and Time
The system date and time can e programmed through the
2480’s we interface. This should e done efore streaming
ecause video may e overlaid with the date, or time, or oth if
OSD is ena led.
3.6 Stream Configuration
In most cases, stream configuration will e done once during
initial system setup and left unchanged thereafter. For example,
settings such as NTSC vs. PAL, or image size, are typically left
unchanged after initial setup, though this is not a requirement.
If a configuration setting is changed on a streaming channel,
the channel will stop streaming momentarily and then start
streaming again with the new settings in effect. Other channels
will continue to stream while the affected channel is eing
reconfigured.
3.6.1 Image Format and ncoding
Various image format and encoding attri utes must e
configured for each input channel:
•Input format. The 2480 supports two analog video input
formats: NTSC and PAL. One of these formats must e
selected for each video input channel.
