Battery Replacement
This device may include a lithium battery powered circuit. If the battery is incorrectly replaced
or mistreated, there is a danger of explosion and a risk of personal injury. Do not attempt to
recharge the battery, disassemble it, immerse it in water, or dispose of it in a fire. Battery
replacement may only be performed by authorized service personnel.
Rack Mount Installation
When installing this device in an instrument rack, the following factors must be accounted for:
Enclosed Racks: Enclosed racks must provide adequate ventilation. Make certain that the
rack is not overly crowded and note that each unit in the rack generates its own heat. An
enclosed rack should have louvered sides and a fan to circulate cooling air. The maximum
temperature for the equipment in this environment is 45°C.
1.
When mounting the unit in an enclosed rack with a ventilation fan at the top of the rack,
note that excessive heat generated by devices at the bottom of the rack can be drawn
upward and into the ventilation slots of units located at the top. Make certain to provide
adequate ventilation for equipment installed at the bottom of the rack.
Open Racks: Make certain that the rack frame does not block the ventilation slots on the
instrument cover. If the device is installed on sliders, check the unit when seated all the
way into the rack to make certain that ventilation slots are not blocked.
2.
Ventilation
Slots in the instrument cover are provided to allow ventilation for heat dissipation. To ensure
safe, reliable operation, these openings must not be covered or blocked.
Disconnect Power
If any of the following events are noted, immediately disconnect the unit from the outlet and
contact qualified service personnel:
If the power cord becomes frayed or damaged.●
If liquid has been spilled into the device or if the device has been exposed to rain or water.●

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].

RS232 PORTS: For connection to console ports on target devices. Standard DB9
connectors configured as DTE ports. The RS232 ports are similar to a serial port 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.
4.
Ports 1 and 2 are System Setup Ports, which are used for communication during
set-up and configuration. Note that Supervisor Level command access cannot be
disabled at these ports.
●
Ports 1 and 2 can either be connected to a PC or modem. Connection to a modem
allows control by a remote PC.
●
Option Switches: A bank of eight DIP switches, which are used to set the default baud
rate, handshake, message type, and duplex mode. Option Switch functions are described in
Section 4.2.

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.
