Black Box MX910A User manual

1
Multiplexes two
RS-232 devices into
one RS-232 modem
link.
Merges data channels
into one data stream,
transmits them, and
then separates them
into their original
channels.
Command mode uses
standard A com-
mands, just like an
ordinary modem.
Supports end-to-end
flow control on all
ports.
Requires no AC power
or batteries.
T
he MicroStat-2 is a miniature
statistical multiplexor that
multiplexes two async channels
over one async connection. The
mux on the other side then
demultiplexes the data, allowing
two async serial connections at
the same time over one line.
Its operating data rate goes up
to 38. kbps, and it uses special-
ized circuitry and V.3 + modem
technology to monitor and
prioritize data flow.
Double the efficiency of a dialup
or leased-line modem link.
KeyFeatures
MICROSTAT-2
The MicroStat-2 automatically
senses the data rate of the local
DTE device upon start up. And
you can configure local and
remote multiplexors from either
of the local ports. It also features
remote loopback tests and
hardware and software flow
control.
Efficient modem operation is
guaranteed, thanks to the
multiplexor’s enhanced AT
Command Set configuration.
A status LED lights when one
of the ports is receiving or
transmitting data. And flexible
flow control includes hardware
or software.
The MicroStat-2 has three
serial connectors: a DB25 male
connector for attaching to a
modem and two RJ- 5 connec-
tors for attaching to serial devices
such as computers, terminals, or
plotters.
The multiplexor must be used
in pairs.

Recognize any of these
situations?
• 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.
• It’s 9 p. m. and you need help,
but your vendor’s tech
support line is closed.
According to a 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 paid.
At Black Box, we guarantee
the best value and the best
support. You can even consult our
Technical Support Experts before
you buy if you need help selecting
just the right component for your
application.
