Multiplex two, four, or
eight async RS-232
data streams onto one
sync line.
Quick, intuitive on-
screen configuration
on a PC or terminal
attached to Port 1.
New configurations
are automatically
cross-loaded from the
local mux to the
remote mux.
Channel data rates
from 300 to 19,200 bps;
composite data rates
from 9.6 to 64 kbps.
Set Composite output
to RS-232 or V.35 via a
switch.
Y
ou know that the phone bill will
be ugly (if it isn’t already) if you
don’t consolidate your multiple
data lines into one. You could use
a multiplexor to cut down on
costs—but you know what that
will mean. Charts. DIP switches.
Opening up the case and fiddling
with jumpers every time you move
equipment…
Not with our MultiMuxes it
won’t. You can multiplex two, four,
or eight async lines onto one sync
line with very little fuss and
absolutely no hassle.
To get the mux ready, just plug
a PC or terminal into channel port
1, disconnect the composite link,
enter a hotkey sequence and a
password, and the MultiMux
displays a configuration menu
right on your screen. You can step
through all the available options in
moments, using only the spacebar
and the [Enter] key.
Sharing a line has never been easier:
On-screen configuration, automatically sent
from mux to mux, makes setting up
these units as smooth as silk.
Key Features
MULTIMUXES
Even better, as soon as as you
reconnect the active line to the
composite port of a MultiMux
you’ve just configured, it will
automatically send the new
configuration to the remote mux.
The MultiMuxes’ channel
ports are asynchronous RS-232
serial interfaces. They are ten-pin
RJ-50 female jacks, but short
adapter cables are included for
each port that patch to DB25
female connectors.
Their default data rate and
format are 9600 bps, 8 data bits,
no parity, and 1 stop bit, but you
can set them to any of twelve
speeds up to 19,200 bps, and you
can choose any of a number of
different data formats (see
Specifications on the next page).
You can set the channel ports to
use eight wires or only three; if
you choose the eight-wire option,
you can also choose between
software and hardware flow
control. (But, again, a few fast
presses of [Space] and [Enter] is
all it takes to get going.)
The composite port is a
synchronous serial port in the
form of a DB25 female connector.
Slide a switch on the back of the
MultiMux to make the port either
an RS-232 interface (for connec-
tion to an RS-232 synchronous
modem and an analog line) or a
V.35 interface (for connection to a
CSU/DSU and a digital line). (To
attach regular V.35 cables to this
port, you will have to purchase
our V.35 Adapter, product code
FA058.)
Data rates on the composite
side range from 9.6 to 64 kbps; the
MultiMuxes will automatically
negotiate the highest speed they
can get.
