W

hy spend money on terminal

server ports that you’ll
probably never use? Some
companies never give you the
option of buying only what you
need, pushing an 8- or 16-port
server when all you really want
is a single-port model.

As always, Black Box has
what you want. The Compact
Single-Port Terminal Server gives
you the freedom to easily—and
economically—add one port
for each new user as the need
arises. Best of all, this lightweight
terminal server actually costs less
than the per-port cost of most
multiport terminal servers.

This low-cost router also
ensures you that you’ll get high
performance from your serial-to­network connections.

Optimized for network
and terminal performance, the
Compact Single-Port Terminal
Server provides true terminal baud
rates. The unit is designed for the
single user or device, so you can
enjoy the benefits of consistent,
full-speed data throughput instead

Simplify! If you need only one port, then buy

only one port. It’s the cost-effective way to go.

Key Features

COMPACT SINGLE-POR T TERMINAL SERVER

of accepting the often lower
performance of a shared terminal
server. Its RS-232 port supports
speeds from 50 to 115,2000 bps,
as well as hardware flow control,
software flow control, and full
modem controls.

With the terminal server,
virtually any type of asynchronous
RS-232 device can be integrated
with a TCP/IP-based Ethernet
network. RS-232 devices
communicate through an Ethernet
LAN by bidirectionally translating
async to IP and IP to async. Once
it’s installed and configured, you
can connect your PCs, printers,
modems, and hosts to the LAN.
There’s no need for a point-to-point
link or a complex, cumbersome,
and expensive wiring scheme.

The Compact Single-Port
Terminal Server can be deployed
different ways. Use it, for example,
to connect a legacy serial device
to your LAN so you can control
and monitor the device remotely.
Or use it to provide a dedicated
link between two workstations
at separate locations. In this

application, the Single-Port
Terminal Server uses your existing
network backbone as the transport
medium. You can also space two
Compact Single-Port Terminal
Servers apart on your network and
use them as serial-line extenders.

The device supports a full
complement of the industry­standard TCP/IP Internet Protocol
suite, including Rlogin, Telnet,
Reverse Telnet (raw sockets),
PPP, SLIP, and SNMP. You can
connect a device such as a PC or
a terminal that needs to dial into a
LAN (Telnet). Or you can connect
a data-collection device that needs
to be controlled from a LAN
(Reverse Telnet), such as a modem
or printer. Because the terminal
server supports raw sockets,
there’s no need to spend a lot of
time writing programs and dealing
with Telnet overhead to make your
LAN node communicate with your
RS-232 device.

The terminal server also
allows a remote user to dial into
the Ethernet backbone and access
the TCP/IP host. TCP/IP hosts and

So you have three devices to link to

your 10BASE-T Ethernet network?

Then three Compact Single Port

Terminal Servers will do the job.

users can even share a modem
and dial out to the Internet or other
BBS services.

The latest version of the
terminal server has several
improvements. For instance, you
can now configure the device’s
IP address via PING. Just enter
the unit‘s Ethernet address into a
client host’s ARP table and, when
the client ”PINGs” that IP address,
the Compact Single-Port Terminal
Server automatically assigns itself
the IP address that it finds inside
the PING packet.

The updated Compact Single­Port Terminal Server also makes
reconnecting to Telnet easier. If
you use the device to originate
a standard or raw-mode Telnet
session, the terminal server can be
set up to automatically re-establish
the session if it‘s lost or broken.
What’s more, you can now use
Telnet to access the device’s
command line interface (CLI).

Firmware enhancements also
allow you to set a TCP timeout,
where TCP socket (raw Telnet)
connections automatically shut
down if the terminal server doesn’t
experience packet activity for a
defined period of time.

Installation and configuration
are easy. The Compact Single-Port
Terminal Server is completely self­contained, requiring no additional
software to be loaded into the unit
or onto a host. For configuring
and managing the terminal server
from connected data terminal
equipment (such as a PC), we
provide a 4-foot (1.2-m) DB9
female-to-RJ-45 serial terminal
cable.

To preserve your configuration
settings during power outages, the
system‘s parameters are stored in
non-volatile RAM.
