The Code Operated Matrix Switch (COMS for short) is a versatile microprocessor-
1. Specifications
Code Operated Matrix Switch

controlled electronic switch. It allows any of its
ports to communicate with any other connected
port, or any pair of ports to communicate
simultaneously.
For example, a number of terminals or
computers can share several peripheral devices,
such as printers or modems. A simple code from
any terminal or computer links it to the desired
peripheral.
Here’s another application: one computer is
connected to a laser printer, while another
computer is simultaneously connected to a dot-
matrix printer. Later, the printers could be swapped
(as in an X-switch configuration) without the need
to change or move any cables.
The standard Code Operated Matrix Switch has
five ports that support any combination of input,
output, or bidirectional devices. The Switch has 32K
of RAM with approximately 31K devoted to
buffering. The 4-Port Expansion Board
(Model SW541-C) provides four additional
input/output ports (see Appendix B for
instructions on setting it up).
This manual includes a quick-reference section,
Appendix C. If you’re familiar with the operation of
the COMS, use the charts in that section to set up
the Switch. If not, proceed through Sections 3, 4,
and 5.
NOTE: This manual will take you through installa-
tion, operation, and troubleshooting for the
Code Operated Matrix Switch in both the
five-port and nine-port versions. See
Appendix B for instructions on setting up
the 4-Port Expansion Board.
You’ll need an edged or pointed object small
enough to set DIP switches to install the Switch.
These are the steps to follow for installation:
1. Set the internal option DIP switches.
2. Configure shunt jumpers for DTE or DCE.
3. Connect devices to the switch ports.
4. Supply power to the Code Operated Matrix
Switch.

CHAPTER 3: Installation
3.1 Setting the Internal DIP Switches
Remove the cover of the Switch’s enclosure to
expose the PC board.
Figure 1 shows the location of the Code Operated
Matrix Switch’s internal DIP switches. There are two
types:
1. Individual Port Switches (see Section 3.1.1)
2. System Switches (these apply to all ports; see
Section 3.1.2)
NOTE: DIP Switches may have different
designators to indicate the “ON” and “OFF”
settings. In this manual, “ON” is equivalent
to “Closed” and “OFF” is equivalent to
“Open.”
3.1.1 INDIVIDUAL PORT CONFIGURATIONS
A number of options can be configured for each
port individually. You can select:
• Baud rate: 110, 300, 600, 1200, 2400, 4800, 9600,
or 19,200 bps
• Parity: Even, odd, or none
• Data bits per word: 7 or 8
• Flow Control: Hardware (DTR/CTS) or software
(X-ON/X-OFF)
• Break detection: Break to disconnect or ignore
breaks

On the standard 5-port model, the DIP switches that
correspond to each port are:
• Port 0: SWA
• Port 1: SWB
• Port 2: SWC
• Port 3: SWD
• Port 4: SWE
For the 4-Port Expansion Board:
• Port 5: SWH
• Port 6: SWI
• Port 7: SWJ
• Port 8: SWK
Table 1 lists the individual options and settings for
each port switch.
3.1.2 SYSTEM CONFIGURATIONS
In the lower left corner of the printed circuit board
are two DIP switch banks, SWF and SWG, for
configuring the system. Switch SWG is reserved for
future use. Switch SWF uses the first four positions,
with Positions 5 through 8 reserved for future use.
The settings and functions of the first four positions
of SWF are given in Table 2. Check the chart, and
then use a pointed object, such as a small
screwdriver, to set the bank.

Lead Pass-Through
This function allows the COS II either to pass
hardware-handshake leads to connected devices or
to block them. If they are blocked, the leads will still
be used to regulate the internal buffer of the
Switch. The following table shows the behavior of
the COS II for different combinations of devices.
Table 2. Leads Passed Through.

NOTE
To use the saving function of the
SW540A-R3, DIP switch F position 1
must be OFF.

3.2 Configuring Shunt Jumpers for DTE or DCE
Each of the five (or nine) ports has a bank of shunt
jumpers located next to its port connector on the
rear of the internal board or boards. (See Fig. 1 for
their location.) These jumpers allow each port to be
configured as either Data Terminal Equipment
(DTE) or Data Communications Equipment
(DCE). You don’t need a crossover cable to connect
your equipment to the Code Operated Matrix
Switch—just standard straight-through cabling.
Shunt jumpers are fragile. When removing them,
use a small flathead screwdriver or IC remover. With
a screwdriver, use a gentle motion, prying from one
end of the shunt. When installing, press down
gently only after you have made sure all pins are
above holes.

shunt setting to the opposite of the one
