Since each port can handle a
variety of data rates and formats,
you can mix older plotters with
newer laser printers and fast (up
to 19.2 kbps) async modems.

When you use the COS II with
printers or plotters, you can send
your data to the best available
output device without having to
turn knobs, press buttons, or
configure software. And when
you set the COS II to look for a
“pause period” before
recognizing a control sequence,
graphics files pass safely through
the COS II without causing

Key Features
CODE OPERATED SWITCH II
connect it and the PC/terminal of
your choice to the COS II. You’ll be
able to manage lathes, meters,
controllers, and more from your
office or data center. And if you
write a program for the master
PC that includes the COS II’s
control codes, the PC can
manage those devices without
your even being there.

The COS II can convert
between differing data rates,
data formats, and types of flow
control, and its 8-KB buffer
preserves your data intact
through these conversions.

In short, the COS II has the
flexibility to adapt to nearly any
group of serial devices. But if you
have unusual requirements, we
can custom-configure a COS II
for you. Call Black Box Technical
Support for more details.

Connect your PC to a laboratory device, a laser printer, a minicomputer,
and a modem. Send and receive data almost transparently—the COS II
resolves all of the differences between data rates and formats without
any additional hardware or software.

Access several different types of printers and plotters through the
COS II. It buffers data, overcomes flow-control differences, and handles
graphics data smoothly.
