All connections can be

Point D to Point E?

The Code Operated Matrix

Switch (COMS) might be just what

you need. It performs any-to-

any

switching between its five

ports in

response to ASCII-character-

based commands. If you have

more than five devices, you can

add the 4-Port Expansion Board

for a total of nine ports. Or you

can even cascade COMSes.

It doesn’t matter if your

devices aren’t absolutely

compatible. Each port on the

COMS can be independently

configured for data rate, data

format, flow control, and break

detection. You can also

independently set each port as

DTE or DCE, so you can use

straight-through-pinned

cables to

connect most devices.

By sending the proper

commands, any port can connect to

Switch up to nine serial devices—any device to any device—without extra conversion hardware or

software.

During the day, one PC can receive orders through your

while another directs an RS-232 industrial controller to

fill the

orders. At closing, the first PC can send reports to

the printer

while the second uses the modem to relay info to HQ.

Depending on the requirements of the job, each of your four PCs

can print to any of your five serial printers.

and disconnect from any other port,

or (as a third party) make or break a

connection between any two other

ports. There can be as many

simultaneous connections through

the COMS as the number of ports

will permit. On a base unit with

five ports, two simultaneous

connections are possible; on a

unit

with the Expansion Board

installed,

as many as four such connections

are possible.

(The COMS has a 31-

KB buffer

to keep data intact, even

with four devices sending at

once.)

In emergencies, or when John

their

peripherals, one command

can

break all existing connections.

If you should ever have

problems, another command

resets the COMS. You can set the

unit’s DIP switches to clear or

maintain existing connections

when the unit is reset.
