Eagle 450 Installation and Technical Manual, Rev. 00
For best reliability and printer performance, your parallel printer cable should be no longer than
six feet.
NETWORK CONFIGURATION
The Eagle 450 includes as standard both an RJ-45 10BaseT and a 15-pin AUI Ethernet connector
attached to the on-board Ethernet controller. You can use either connector to attach the Eagle 450 to your
network, then use AlphaTCP for industry-standard TCP/IP networking on your LAN or the Internet.
You cannot use both Ethernet ports at the same time.
10BaseT Cabling
10BaseT connections use 100 ohm unshielded twisted pairs, with at least two pairs per cable (one set of
pairs for transmitting data and another for receiving). 10BaseT cables terminate in eight pin RJ-45
connectors with the following pin assignments:
RJ-45 Pin
Number Signal Name
1 Transmit Data +
2 Transmit Data -
3 Receive Data +
6 Receive Data -
The 10BaseT specification allows a maximum distance of 100m (approx. 300 feet) between the computer
and hub.
EAGLE 450 UPS STATUS PORT
The UPS status port on the back panel of the Eagle 450 is a male DB-9 connector. The UPS system also
has a male DB-9 connector for its switch contact port. To connect the UPS to the computer you need a
cable with two female DB-9 connectors. The following table shows the pinout connections required to
make this cable. You need an 8-wire cable, and both grounds are necessary!
