FEATURES
• Switch common-port access between 16
ports.
• Convenient code-based switching means
you can control all your devices from
one computer.
• No accidental switching—code-
repetition feature separates switch
commands from data.
• Optional broadcast mode distributes
data to all ports.
Connect one computer to as many as 16 RS-232
peripheral, laboratory, or data-input devices.
OVERVIEW
Bring the ease of “soft switching” to large RS-232
applications with the Code-Operated Switch-16 (COS-16).
It works just as smoothly as a mechanical switch, but you
activate it by sending a two-character ASCII code from your PC
rather than by pressing a button or turning a knob.
Switching is simple. From a PC, modem, or terminal
installed on the common port, just send the prefix (arming)
character to alert the COS-16, then send the port-selection
character. Electronic relays instantly direct data to the proper
port.
With code-based switching, you can use your local or
remote PC to receive data from or transmit data to any of a
huge collection of RS-232 terminals, peripherals, or lab or
industrial equipment.
The COS-16 can handle all varieties of data, including
binary and graphics files, even though these can contain exact
equivalents of the COS-16’s two-character switching codes.
When you use the COS-16’s “code repetition” feature, the
unit waits for two, four, or even eight consecutive occurrences
of the prefix character before recognizing a selection
character and redirecting your data. This precaution
dramatically lowers the odds of a switching error.
The COS-16 also has a “broadcast mode” feature. In
broadcast mode, the device on the common port can
simultaneously transmit to all connected devices. This makes
sending bulletins and upgrading firmware much easier.
With the COS-16, you can switch between up to 16 devices.
The COS-16 fits any site that relies on a large number of
RS-232 devices—peripherals, terminals, lab equipment, etc. It’s
ideal for monitoring remote equipment or data-collection
devices, polling bar-code readers, exercising units under test,
or broadcasting to market-quote displays. And the COS-16
runs at data rates up to 19.2 kbps.
We also offer an RS-422 version of the COS-16 as a special
quote; for details, call us at 724-746-5500.
Additional equipment you may need
• To rackmount a COS-16, you’ll need one Rackmount Kit.
• An asynchronous RS-232 modem for long-distance off-site
control of your devices.
• An RS-232 line driver for control from an office on another
floor or from a data center in a nearby building.
• RS-232 cable.
• AC and data-line surge protectors.
• Interface converters to connect RS-422, RS-423, RS-449,
RS-485, V.35, or X.21 devices to the COS-16.
• A country-specific power cord for operating the COS-16
outside of North America.
• Communications software.

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.
Don’t waste time and money—call Black Box today.
