1. Introduction
The CMS-16 Console Port Management Switch provides secure, in-band and/or out-of-band
access to RS232 console ports and maintenance ports on UNIX servers, routers and other
network equipment. System Administrators can access remote devices in order to change
configuration parameters, connect users to restricted ports, collect buffered data, and perform a
variety of other administrative functions.
Versatile Connectivity
Up to 16 different devices can be connected to the CMS 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.
Easy Set-Up and Operation
Configuration of the CMS is simple. A menuing system is used to select parameters, and enable
options. The CMS can easily adapt to the requirements of almost any data communications
application.
Limited Command Access
The CMS is ideal for situations that require limited access to important commands. Two
security levels allow each port to function as a Supervisor Port or 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 provided by
their password. Each individual port can be assigned its own unique, user-defined password, up
to sixteen characters long.
Non-Volatile Memory
If AC power to the unit is lost or interrupted, the CMS's non-volatile memory will retain
user-defined parameters and port connections.
Modem and Telnet Communication
The CMS can be controlled by a local PC that communicates with the unit via cable, or
controlled remotely via external modem or telnet connection. Your terminal emulation or telnet
program is used to send commands to connect ports or display status.
Configuration Backup

Once you have configured the CMS to fit your application, parameters and options can be saved
to an ASCII text file on your PC. This allows you to quickly restore user-selected parameters if
the unit configuration is accidentally altered or deleted. Saved parameters can also be uploaded
to other CMS units. This allows rapid set-up when several units will be configured with identical
or similar parameters.
Typographic Conventions
Throughout this User's Guide, typefaces and characters are used to denote the following:
^
(e.g. ^X)Indicates a control character. For example, the text "^X" (Control X)
indicates the [Ctrl] key and the [X] key must be pressed
simultaneously.
COURIER FONT Indicates characters typed on the keyboard. For example, /E or /P 02.
[Bold Font] Text set in bold face and enclosed in square brackets, indicates a
specific key. For example, [Enter] or [Esc].
< > Indicates required keyboard entries: For Example: /P <n>.
[ ] Indicates optional keyboard entries. For Example: /W [n].

3. Getting Started
This section provides a brief overview of basic CMS capabilities, and describes simple tests that
can be used to determine if the unit is operating properly.
3.1. Communication Parameters
The Option Switches, located on the instrument back panel, select default operating settings.
Switch functions are summarized in Section 4.2, and on a label on the CMS unit.
When the unit is shipped from the factory, the Option Switches are set for 9600 baud, 8 Bits-No
Parity, RTS/CTS handshaking, verbose response, and command echo ON (all switches Down).
For this overview only, use the default switch configuration. Set your communications program
(e.g. ProComm©) to the parameters listed below. After completing this overview and installing
the unit, please refer to Section 5 for instructions on selecting faster communication speeds and
other parameters.
9600 Baud●
RTS/CTS Handshaking●
Full Duplex (Command Echo ON)●
8 Bits, No Parity, 1 Stop Bit●
Using Other Parameters for this Overview (Optional):
If desired, the CMS can match the parameters used by your communications program. Refer to
Section 4.2 and configure Option Switches accordingly. After changing the switches, reset the
CMS; press and hold both the SET and CLEAR buttons, release only CLEAR, wait for the Port
LEDs to flash, and then release the SET button.
Note: If Option Switches are changed, new settings will not take effect until the
unit is reset.

3.2. Apply Power to the CMS
Connect the CMS to an appropriate power source. Press the Power Switch ON. The ON LED
should light, and the RDY LED should begin to flash. When connecting power to a DC unit,
please refer to the additional instructions in Section 4.1.
CAUTION: This device should only be operated with the type of power source
indicated on the instrument nameplate. If you are not sure of the type of power
service available, please consult your local power company.
3.3. System SetUp Ports
In order to ensure access to important command functions, Ports 1 and 2 are designated as
System SetUp Ports; the Supervisor Mode cannot be disabled at these ports. Ports 1 and 2 will
always allow password protected access to all CMS command functions, even when the unit has
been reset to the default state.
Therefore, Ports 1 and 2 are generally used for communication during initial set-up and
configuration, or after the unit has been reinitialized (reset) to default parameters.
Note: For more information on System SetUp Port capabilities, please refer to
Section 5.2.
3.4. Connecting your PC to the CMS
The CMS can either be controlled by a local PC that communicates via cable, controlled via
external modem, or controlled via TCP/IP network. For this overview, a local PC running
ProComm (or a similar communications program), will be cable connected to Port 1.
Note: Communication via Modem (Optional): If desired, this overview can also
be performed via modem. Section 4.4 describes the procedure for connecting a
modem to the CMS.
Attach a standard null modem cable to your PC COM port. Make certain to connect to the
COM port used by your communications program.
1.
Connect the other end of the cable to CMS Port 1. For a description of the port interface,
please refer to Appendix A.

This completes the introductory overview of the CMS. Please proceed to Section 4 and
Section 5 for complete installation and configuration procedures.
4. Hardware Installation
4.1. Connecting Power to the CMS Unit
The CMS is available in both AC and DC powered versions. When connecting AC or DC power
to the CMS, proceed as follows:

CAUTION: This device should only be operated with the type of power source
indicated on the instrument nameplate. If you are not sure of the type of power
service available, please consult your local power company.
4.1.1. AC Powered Units
Plug the supplied power cable into the receptacle on the CMS back panel and then connect the
power cable to a grounded AC outlet. The AC powered version of the CMS features a self
adjusting power supply that automatically adapts to power supplies between 90 and 250 VAC.
4.1.2. DC Powered Units
The DC terminal block features two bus inputs as shown in Figure 4.1 below. This allows the
user to connect only one DC power source, or connect two DC power sources where the second
source functions as a backup.
When connecting the CMS to your DC power source, first remove the clear protective cover
from the DC terminal block, attach the wires from the -48V DC power source to the screw
terminals, connect your ground line to the labeled ground screw, and then replace the protective
cover.
Figure 4.1: Terminal Block Assembly (DC Units Only)
4.2. Configure Option Switches
When the CMS is shipped from the factory, the Option Switches are configured for 9600 baud, 8
Bits-No Parity, RTS/CTS handshaking, verbose command response, and command echo ON (all
switches Down). These settings are compatible with most applications. If the default settings
are not compatible with your application, change the switch settings as follows.
The Option Switches should be configured to match the parameters your control device will use

when communicating with the CMS. This will ensure access to command functions, even if the
unit is initialized to default parameters.
Note:
If the Option Switch configuration is changed, new parameters will not take
effect until the unit is initialized as described in Section 4.3.
●
Operating parameters (baud rate, parity, etc.) can be selected for each port
using the /P command as described in Section 5.5. The /P command can
select different parameters for each CMS port.
●
When the CMS is initialized, parameters will return to settings specified by
the Option Switches.
●
4.2.1. Default Baud Rate (Sw1, Sw2, Sw3)
Option Switches one through three select the default baud rate for all CMS RS232 Ports. The
default baud rate must match the rate your control device will use when communicating with the
CMS. If the control device will communicate via modem, select a default baud rate that is
compatible with the modem.

Determine which port will be used for connection to the new device (e.g. Port 3).2.
Check Buffer: Type /S [Enter] to display the Port Status Screen. Check the "Buffer
Count" column, which lists the amount of data stored in the buffer for each port.
If the Port Status Screen shows data stored in the buffer for the desired port, type
/E xx [Enter] to clear the buffer (where xx is the desired port number).
.
Note that cleared data cannot be recovered.b.
3.
Use an appropriate DB9 cable to connect the RS232 serial port on the device to a DB9
port on the CMS.
External Modems and other DCE Devices: Use a standard serial modem cable..
PCs and other DTE Devices: Use a standard null modem cable.b.
4.
Select communication parameters for each port as described in Section 5.5.
4.5. Application Example

Figure 4.2: CMS Application Example (Not to Scale)
The example in Figure 4.2 shows one of many possible installation configurations for the CMS.
In this example, ports have been configured as follows:
Network Port: The Network Port allows telnet access by remote Supervisors and/or
Users. When a telnet connection is established, the CMS will prompt the caller to enter a
password. If the Supervisor Password is entered, the CMS will recognize Supervisor Level
Commands; if a Port password is entered, the CMS will only recognize User Level
Commands. Supervisors are allowed to adjust port configuration, connect to any port, or
review unit status. Users are only permitted to review status and connect to ports that are
allowed by their Port password.
●
Port 1 (System SetUp Port): This port has been left open in order to permit on-site
service personnel to access the Command Mode without disrupting other ports. Since
Port 1 is a System SetUp Port, the service tech is allowed password protected access to
Supervisor Level commands, and is able to connect to any port, change configuration, or
display unit status.
●
Port 2 (Modem Port): An external modem has been installed at Port 2. This port has also
been configured for Modem Mode, which allows definition of a modem reset string,
initialization string, and hang-up string. When a caller contacts the CMS unit via modem,
a password prompt will be displayed. If the Supervisor Password is entered, the CMS will
permit access to Supervisor Level Commands; if a Port password is entered, the CMS will
only recognize User Level Commands. Supervisors are allowed to adjust port
●

configuration, connect to any port, or review unit status. Users are only allowed to review
status and connect to the ports allowed by their Port Password.
Ports 5, 7, and 9 (User Ports): The Port Password "COLOCATION1" has been assigned
to these three ports. If the CMS is contacted via the Network Port or Modem Port, and this
password is entered at log in, Users will only be able to review status and connect to the
devices attached to Ports 5, 7, and 9.
●
Ports 12, 14, and 16 (User Ports): The Port Password "COLOCATION2" has been
assigned to these three ports. If the CMS is contacted via the Network Port or Modem
Port, and this password is entered at log in, Users will only be able to review status and
connect to the devices attached to Ports 12, 14, and 16.
●
Note that in this example, Ports 3 through 16 could also be a mixture of ports connected to
external modems, and ports connected to devices such as file servers or archives. This would
allow remote users to dial in and access a specific file server or archive after entering a valid
Port Password at log in.
5. Configuration
5.1. Access to the CMS Command Mode
When the CMS Command Mode is active, commands can be invoked to select parameters, and
connect or disconnect ports.
Note: Command Mode cannot be accessed from a Buffer Mode Port, Passive
Mode Port, or any port that is currently connected to another CMS port.
Start your communications program (e.g. ProComm©). Make certain the CMS and
ProComm are set for the same parameters (e.g. baud, parity, etc.).
1.
Access the Command Mode.
Local Access: To access the command mode from a local PC that is connected to
the CMS via cable, press [Enter].
If you have already hit other keys, press [Enter] twice. There can be no other
characters preceding [Enter].
i.
If the Supervisor Password has been defined, the password prompt will be
displayed. Key in your Supervisor or Port password and press [Enter]. The
"CMS>" prompt will appear.
ii.
.
2.

Modem Access: To access the command mode via modem, proceed as follows:
Dial the number for the external modem connected to the CMS.i.
If you have defined the Supervisor Password, a prompt will be displayed.
Key in your Supervisor or Port password and press [Enter]. If the Supervisor
Password has not been defined, just press [Enter]. The "CMS>" prompt will
appear.
ii.
b.
Network Access: In order to access the CMS command mode via network, the IP
Address, Subnet Mask and Gateway Address must first be defined. Therefore,
network access is not available during initial configuration.
After Network Port Parameters are assigned as described in Section 5.5.3, the user
may connect to the CMS via network using the following procedure:
Telnet to the CMS's IP Address. For example, if the IP Address is
"192.1.1.1", on a UNIX system, the Telnet command would be invoked as
follows:
$ telnet 192.1.1.1 [Enter]
i.
Note that if the Telnet connection to the CMS is refused, this probably means
that the network port is busy, or that the IP Security feature has denied the
connection.
ii.

5.2. System SetUp Ports
As discussed previously in Section 3 of this User's Guide, Ports 1 and 2 are designated as System
SetUp Ports. Ports 1 and 2 will always permit password protected access to Supervisor Level
command functions, even when the unit is reset to default parameters.
In order to ensure that access to command functions is always available, Ports 1 and 2 cannot be
configured as Buffer Mode or Passive Mode Ports. Buffer and Passive Mode Ports are not able
to access the Command Mode. In addition, Ports 1 and 2 always permit password protected
access to Supervisor Level commands; the Supervisor Mode cannot be disabled at these two
ports.
