PRODUCT OVERVIEW
The 108TX industrial network switch is designed to meet
the most demanding industrial communications require-
ments while providing high throughput and minimum
downtime.
The 108TX provides eight RJ-45 auto sensing 10/100BaseTX ports. All ports are full/half duplex capable, using
leading-edge Ethernet switching technology. The 108TX
auto-negotiates the speed and fl ow control capabilities
of the eight TX port connections, and confi gures itself
automatically.
Since the 108TX is auto sensing, there will be no need to
make extensive wiring changes if upgrades are made to
host computers, plant systems, or Ethernet I/O modules.
The switching fabric simply scales up or down automati-
cally to match specifi c network environments.
The 108TX supports up to 2,000 MAC address-
es, enabling these products to support extremely
sophisticated and complex network architectures.
The 108TX is an ideal candidate for upgrading existing
hubs and repeaters to increase bandwidth and determinism by virtually eliminating network collisions. The
108TX combines affordability and the plug & play
simplicity of the unmanaged hub.
The 108TX can simplify plant wiring by eliminating
the need to bring data acquisition and control network
connections back to a climate controlled environment.
The 108TX has extended operating environmental
specifi cations to meet the harsh needs of the industrial
environment. For cost savings and convenience the
network switch can be DIN-Rail mounted alongside
Ethernet I/O or other Industrial Equipment.
To increase reliability the 108TX includes dual
redundant power inputs. LEDs are provided to
display the link status and activity of each port.
