Potential
Uses |
| EtherLynx 2000 cameras and the computers that operate the
FinishLynx software communicate in the TCP/IP protocol over an Ethernet network. A number
of additional computers and Etherlynx cameras can be added to the network. |
Media
|
| 10-Base-T is the preferred medium for use with
FinishLynx. This medium uses a hub topology where the failure of one branch in the network
will not affect other branches. The limitations are the shorter distances over which the
cable can be used, and that the cables are generally not as suitable for permanent outdoor
installations. 10-Base-2 uses co-axial cable
in a bus topology. Ethernet devices are daisy chained and must have a terminator at each
end of the chain.
10-Base-FL is used for installations where neither
the 10-Base-T or 10-Base-2 media are practical, fiber optic cable may be used. Fiber optic
is the most costly implementation of an Ethernet network and can only be installed by your
local network specialist. |
Specifications
|
10-Base-T
- Requires Cat 5 or Cat 5+ cable (eg. Belden 1700A) with RJ45
connectors
- For extreme outdoor conditions or permanent installations
you may need to use a more durable cable that meets the same electrical specifications.
Contact your local network specialist for more information
- The maximum distance between hubs and devices is 328’
10-Base-2
- Requires RG-58 cable (eg. Belden 9907) with BNC connectors
and 50 Ohm terminators
- For extreme outdoor conditions or permanent installations
you may need to use a more durable cable that meets the same electrical specifications.
Contact your local network specialist for more information
- The maximum length of a segment (between terminators)
without a repeater is 600’
10-Base-FL
- Contact your local network specialist for information
|
Exceeding
Specified Distances |
The distance between cameras and the FinishLynx computer
can be maximized using a number of methods, including:
- locate your Ethernet hub in the field, midway between the
farthest camera and the computer
- purchase an Ethernet repeater or cable extender which can
double the distance you run your cable
|
Note
Well! |
- It is possible to use a mix of media. Make sure your
ethernet hub facilitates the media you wish to use
- If you are using a UPS (see Power Management), the Ethernet
hub or Ethernet extender located in the field must be powered by a UPS
- If two hubs are connected together, one of them must be
equipped with an uplink
- Ideally, your setup will contain only one Ethernet hub
located in close proximity to the FinishLynx computer
