Connecting Components
Your Camera control ODU requires three things, a source of power, a source of
data and an antenna with which to transmit.
Power can be supplied either via the Power Input Connector, or via the RJ45
connector utilising Power over Ethernet. The ODU will automatically switch
between these two inputs, and if both are connected the Power Input Connector
will be preferred.
Data can be provided either via the Data Connector as RS232, RS485 or via
Ethernet using the using the appropriate configuration on your IDU. The ODU
can be configured to automatically select an active data source, selected
between groups of sources or locked to only respond to a specific source.
RS485 control, when used with a Videosys IDU, will operate on up to 1500m
cable lengths. Using Ethernet, cable lengths of up to 100m can be used per
segment. It should be noted that many cheap and readily available range
extending solutions exist for IP networks. RS232 connectivity is only rated for
15M and is provided to allow operators to use equipment such as off-the-shelf
serial to fibre converters.
