Run flexible UTP cable instead of twinaxial in
your AS/400 5250 PC emulation.
Key Features
Proven interoperability with 5250
Standards-based 5250

he IBM 5250 Express protocol,
capable of TCP/IP support, is
quickly becoming the “de facto”
standard for AS/400 PC
emulation. With the Active Star
Hub from Black Box, you’re
guaranteed an upgrade path (via
firmware) to the new protocol for
far less cost than completely
replacing the hub.
The Hub is a state-of-the-art
dual active star that has two host
port connections and 14 device
port connections. It was designed
with protocol-transparent criteria
and is available with either RJ-11
or RJ-45 connectors. This
standards-based, flexible UTP
star solution is a low-cost
alternative to expensive and rigid
twinaxial daisychain cabling.
Each device port is isolated,
assuring that problems won’t be
transmitted throughout the entire
network. Digital Phase Lock Loop
and signal conditioning, noise
suppression, and proven
interoperability assure reliable
and transparent connections with
IBM AS/400, 3X and compatible
terminals, printers, emulation
cards, and remote controllers.
Other Hub features include:
• The Hub is polarity
insensitive as long as host and
device polarities are the same.
• Advanced noise filtering and
signal conditioning means that
the Hub will work with lessergrade cabling systems.

• You wait more than 30
minutes to get through to a
vendor’s tech support.
• The so-called “tech” can’t
help you or gives you the
wrong answer.
• You don’t have a purchase
order number and the tech
refuses to help you.
According to a recent survey
by Data Communications
magazine, 90% of network
managers surveyed say
that getting the technical support
they need is extremely important
when choosing a vendor. But
even though network managers
pay anywhere from 10 to 20% of
their overall purchase price for a
basic service and support
contract, the technical support
and service they receive falls far
short of their expectations—and
certainly isn’t worth what they
