Cascade units, and the
TEP grows along with
your business.
Memory can double to
64 KB with optional
Memory Expansion.
Five operation modes
handle all types of
situations.
Can be customized to
fit your application.
Optional rackmount kit
keeps the Terminal
Eliminator Plus out of
your way.
Ten LEDs give you
power and port

ay good-bye to separate
consoles for intelligent async
devices, including mainframes,
data PBXs, network management
systems, data loggers, data
concentrators, and intelligent
test-data sets/analyzers. Thanks
to the Terminal Eliminator Plus
(TEP), one terminal can perform
the work of many.
The standard TEP supports
four input devices and one output
device. It also features 32K of
RAM (approximately 31K is
devoted to buffering). You can
expand the TEP with a 4-Port
Expansion Board that boosts the
number of slave devices to eight.
In addition, an optional 32K-
Memory Expansion can double
the device’s memory to 64 KB.
If your application calls for
more than eight slave ports, you
can cascade multiple devices
simply by running the slave port of
one unit to the master port of
another. This cascading method
gives you three layers of TEPs
from a main TEP—for a maximum
of 4096 slave ports.
The TEP lets you clearly
identify lines of data with user-
programmable labels, too. A

KeyFeatures
TERMINALELIMINATORPLUS(TEP)
variety of format options makes it
easy to distinguish data from
different devices on the screen.
The device includes five
operation modes:
Concentrate
The TEP stores slave data in the
buffer until it matches a user-
programmable record description.
Then it’s transmitted out of the
master port on a round-robin
basis.
Broadcast Only
Lets you broadcast messages
from the master port to all
connected slaves.
Concentrate & Broadcast
Sends data in the Concentrate
mode from the slaves to the
master port. Also broadcasts data
from the master port to all
connected slaves.
Conversation
Lets you communicate inter-
actively with an individual slave.
Transparent Conversation
Lets you communicate
interactively with an individual
slave—without stripping or
inserting data into the data
stream.
The TEP works best in
applications where most of the
operator’s console is devoted to
output-log-message and status
reporting—with an occasional
need for interactive responses
from the keyboard.
Our expert Technical Support
staff can custom program your
TEP. They’ll be happy to tailor the
device to fit your particular
multiport async application.
An optional rackmount kit
keeps the TEP out of sight. Other
features include 10 LEDs for easy
monitoring and speeds that range
from 110 to 19,200 bps.
• Concentrate console output from multiple mainframes in a large
computer center to one operator’s console.
• Poll or concentrate output from other devices—bar-code readers,
scales, or security systems—to a master PC.

Installing your Terminal Eliminator
Plus involves four easy steps:
1.Setting the internal DIP
switches.
2.Configuring the DTE/DCE
shunt jumpers.
3.Connecting your devices to
the slave ports and master
port.
4.Connecting the TEP to
electric power.
The TEP uses a dynamic
buffer. Each input device is given
a minimum of 1K of RAM reserved
exclusively for that port, so a
single port cannot monopolize all
of the TEP’s space. The remaining
memory is distributed among all
active ports according to the
current demand.
There are a total of 10 LEDs on
your TEP’s front panel—nine
Port-Status LEDs (numbered 0-8)
and one Power LED. The Power
LED lights up when the TEP is on.
Each Port-Status LED will flash or
blink if the corresponding port is
transmitting or receiving data. The
LED will be steadily lit if there’s a
buffer overflow on the
corresponding port. It will remain
dark if there’s no data activity on
the corresponding port. On
standard units without a 4-Port
Expansion Board, LEDs 5-9 will
remain dark.
