Data Broadcast Units:
Fully regenerate an
async host signal and
broadcast it out to
eight slave ports.
Choose from DB25
or RJ-11 versions.
Buffered Data
Broadcast Units:
Port buffering lets your
connected devices
receive data continu-
ously, regardless of
their speeds.
Parallel Data Broad-
cast/Fallback Unit:
Sends parallel data to
two printers at once,
or “falls back” for
continuous data output.
I
f you want to transmit data to
more than one printer or terminal
at the same time, choose among
our Data Broadcast Units,
Buffered Data Broadcast Units,
and Parallel Data Broadcast/
Fallback Unit. These solutions
get the job done—without losing
signal strength!
Data Broadcast Units
The Data Broadcast Units
enable you to transmit data from
any serial async device to up to
eight printers, modems, or
terminals simultaneously.
The Data Broadcast Units take
the RS-232 signal from your async
host, divide it among eight slave

Key Features
DATA BROADCAST UNITS
ports, and then completely regen-
erate and broadcast each of
those new port signals to their
respective devices.
There’s a model for DB25
cabling and one for RJ-11 cabling
to fit your needs. The DB25 model
is available in 115- or 230-VAC
versions.
Buffered Data Broadcast Units
The Buffered Data Broadcast
Units function in the same way as
the Data Broadcast Units, but they
also feature individually buffered
ports. These let you send async
data to devices operating at
various speeds. You can config-
ure each port for word structure,
baud rate, flow control, and DTE
or DCE operation.
Versions are available for 115-
or 230-VAC power.
Parallel Data Broadcast/
Fallback Unit
This unit lets you send parallel
data to two printers simultaneous-
ly, or designate a backup printer
in case your primary printer fails.
