CHAPTER 2: Introduction
2. Introduction
2.1 Features
The Serial Console Port Manager allows reliable, high-speed connections between
PCs, modems, and other devices using dissimilar baud rates, parity, and
handshaking. It comes in 8-port (product code SW542A) and 16-port (SW543A)
versions. The Port Manager supports communication at speeds up to 115.2 kbps
and features full RTS/CTS hardware handshaking.
Lightning-swift data throughput and full flow control make the Serial Console Port
Manager the perfect data switch for today’s high-speed communications
applications.
V
ERSATILECONNECTIVITY
Up to 8 or 16 different devices can be connected to the Port Manager without the
need to select a common baud rate or parity. Each port can be individually
configured for specific baud rates, parity, handshaking, and various other
parameters and options.
E
ASYSETUP ANDOPERATION
Configuring the Port Manager is simple. A menuing system is used to select
communications parameters and enable or disable options. The Port Manager can
easily adapt to the requirements of almost any data-communications application.
P
ASSWORD-PROTECTEDCONNECTION ANDCOMMANDACCESS
The Serial Console Port Manager is ideal for situations that require limited access
to important commands. The Port Manager has two security levels: Each port can
function as either a Supervisor Port or a User Port, depending on the password
entered at login. Supervisor Ports are allowed to change configuration, display
status, and connect to any other port; User Ports are only allowed to connect to the
ports authorized for their password. You can assign passwords up to sixteen
characters long.
In addition, the Port Manager also supports a Passive Mode that allows connection
to other ports, but does not allow access to command functions.
8
SERIAL CONSOLE PORT MANAGER
NON-V
OLATILEMEMORY
If AC power to the unit is lost or interrupted, the Port Manager’s non-volatile
memory will retain user-defined parameters and port connections.
C
OLLECTINGDATA FROMMULTIPLESOURCES
A Buffer Mode allows the Port Manager to collect data from up to six or fourteen
different devices (all devices except those on Ports 1 and 2) and store that data for
later retrieval.
M
ODULARDESIGN
DB9 jacks provide quick, easy connection to computers, modems, and other LAN
hardware. The Serial Console Port Manager is compact and takes only one unit
(1.75 inches, 4.5 cm) of vertical rack space.
M
ODEMCOMMUNICATION
The Port Manager can be controlled either from a local PC that communicates
with the Port Manager across a cable, or remotely through an external modem.
A communications program such as ProComm is used to send commands to
connect ports or display status.
C
ONFIGURATIONBACKUP
Once you have configured the Serial Console Port Manager to fit your application,
parameters and options can be saved to an ASCII text file on a connected
computer. This means that if the Port Manager’s configuration is accidentally
altered or deleted, you can quickly restore user-selected parameters. You can also
upload this file to other Port Managers, which allows quick setup of multiple units
with identical or similar parameters.

➀ RS-232 Ports: Standard DB9 connectors configured as DTE ports for
connection to switched devices. The RS-232 ports are similar to standard serial
ports on a PC. When connecting a modem, use a standard serial cable. When
connecting a PC or other DTE device, use a null-modem cable.
Ports 1 and 2 are used for communication during set-up and configuration.
When the Port Manager is initialized to defaults, Ports 1 and 2 are the only
ports with access to All (Administrator) commands. Access to Administrator
commands can’t be disabled at Ports 1 and 2, so be careful what you connect to
them.
➁ Setup Switches: A bank of eight DIP switches that you’ll use to set the default
baud rate, handshake, message type, and duplex mode. These Setup Switches
are on the rear panel of 8-port units, but they’re on the bottom of 16-port units.

CHAPTER 3: Getting Started
3. Getting Started
3.1 Communication Parameters
The Setup Switches, located on the back of the 8-port Serial Console Port Manager
or the underside of the 16-port Port Manager, select default settings for the RS-232
ports. Setup Switch functions are summarized in Section 4.1 (and on a label next
to the switches).
When the Port Manager is shipped from the factory, the Setup Switches are set for
9600 baud, 8 Bits/No Parity, RTS/CTS handshaking, verbose command response,
and command echo enabled (all switches ON).
The rest of this chapter provides a brief overview of the Port Manager’s capabilities.
For this overview only, we’ll assume the default Setup-Switch configuration. Set
your communications program (for example, ProComm
®
) to the parameters listed
below. After completing the overview and installing the Port Manager, refer to
Chapter 5 for instructions on selecting faster communication speeds and other
parameters.
• 9600 Baud
• RTS/CTS Handshaking
• Full Duplex (command echo enabled)
• 8 Bits, No Parity, 1 Stop Bit
Using Other Parameters for this Overview (Optional): If you’d like, the Port
Manager can match the parameters used by your communications program. Refer
to Section 4.1 and configure the Setup Switches accordingly. After changing the
switches, reset the Port Manager; press and hold both the SET and CLEAR
buttons, release only CLEAR, wait for the port LEDs to flash, and then release SET.
NOTE
If Setup Switches are changed, the new configuration will not take effect
until the Port Manager is reset.
3.2 Applying Power to the Port Manager
Connect the power cable to the Serial Console Port Manager and plug the cable
into an AC power source. Press the power switch to turn the Port Manager ON.
The ON LED should light, and the RDY LED should begin to flash.
12
SERIAL CONSOLE PORT MANAGER
3.3 System-Setup Ports
In order to ensure access to important command functions, Ports 1 and 2 are
designated as System-Setup Ports. System-Setup Ports always have access to all Serial
Console Port Manager commands.
Although any Serial Console Port Manager port can be granted access to all
commands, Ports 1 and 2 are the only ports that always have access to all command
functions, even when the Port Manager has been reset to the default state.
Supervisor Mode cannot be disabled at Ports 1 and 2.
Ports 1 and 2 provide a gateway through which the system administrator is
guaranteed access to all commands. Therefore, Ports 1 and 2 are always used for
communication during initial setup and configuration, or after the unit has been
re-initialized (reset) to default parameters.
NOTE
For more information on System-Setup Port capabilities, refer to
Section 5.2.
3.4 Connecting Your PC to the Serial Console Port Manager
The Serial Console Port Manager can be controlled either (a) by a local PC that
communicates across a cable, or (b) through an external modem. For this
overview, assume we’re using a local PC running ProComm (or a similar
communications program) connected with a cable to Port 1; if you’ll be using a
modem link instead, see Section 4.3.
1. Attach a standard null-modem cable to your PC’s COM port. Make certain to
connect to the COM port used by your communications program.
2. Connect the other end of the cable to the Port Manager’s Port 1. For a
description of the port interface, please refer to the Appendix.
13

SERIAL CONSOLE PORT MANAGER
4. Hardware Installation
4.1 Configure Setup Switches
The Serial Console Port Manager has a bank of eight DIP switches that you’ll use to
set the Port Manager’s default baud rate, handshake, message type, and duplex
mode. These Setup Switches are on the rear panel of 8-port units; they’re on the
bottom of 16-port units.
When the Port Manager is shipped from the factory, the Setup Switches are
configured for 9600 baud, RTS/CTS handshaking, verbose command response,
and command echo enabled (all switches ON). These switch settings are
compatible with most applications. If the default settings are not compatible with
your application, change the switch settings as described in this chapter.
The Setup Switches should be configured to match the parameters your control
device will use when communicating with the Serial Console Port Manager. This
allows access to command functions, even if the Port Manager is initialized to
default parameters.
NOTES
On the 8-port Port Manager, the Setup Switches are OFF when UP and
ON when DOWN. On the 16-port Port Manager, please refer to the label
next to the Setup Switches to determine their ON/OFF positions.
Communication parameters (baud rate, parity, etc.) can be selected for
each port using the /P command as described in Section 5.5.3. The /P
command can select different parameters for each Port Manager port.
When the Serial Console Port Manager is initialized, its parameters will
return to the settings specified by the Setup Switches. Changes to the
Setup Switch settings will not take effect until the Manager is initialized.
