Aviom 16/O-Y1 - Manual (Page 15)

Cables Used With A-Net Devices
Aviom suggests using Category 5e (Cat-5e) or better cables when
making A-Net connections between devices (maximum cable run of
500 feet, 150 meters). The Ethernet specification requires the use of
Unshielded Twisted Pair (UTP) cables for all interconnections for best
performance. All Aviom A-Net products require unshielded Cat-5e
cables. Category 6 (Cat-6) cables can also be used.
Do not use shielded Cat-5e cables with A-Net devices.
When purchasing Cat-5e cables, be sure to buy only standard Cat-5e
cables, not those sold as crossover cables. A crossover cable is used
for file transfer between two computers. A crossover cable is not
compatible with your Aviom equipment.
Cable Lengths
Your cable length performance will be affected by a number of
factors including the quality of the cables used, and the number of
devices such as cable couplers used or wall panel interconnections
in use.
To go longer than the maximum specified distance A-Net allows
(500 feet, 150 meters), an A-Net Distributor product can be used as a
signal repeater. Simply insert the A-16D or A-16D Pro into the A-Net
stream at the 500-foot point and the A-Net signal will be refreshed.
Another 500 feet (150 meters) of cable can then be added. This
process can be repeated as many times as required to extend cables.
In fact, any Pro16 A-Net device can be used as a signal repeater.
For long distance applications, fiber optic cable can be used to span
distances up to 50 miles (80km) with the use of devices called media
converters. A media converter changes the Ethernet-based Pro16
A-Net signal to fiber optic at the source location and then back to
Cat-5 at the destination. Several companies make fast Ethernet to
fiber media converters that can be used with your Aviom equipment.
Note: While the Category 5 cables and connectors used on
your Aviom products look like typical computer network
connections, do not connect computers, routers, or other
home and business networking equipment to your Aviom
products.
