Figure 1 - List of System Interface Ports for NC Systems
The NC systems provide secure and versatile console port t management for communication
equipment such as routers, switches, and network devices. They are also the ideal assistant
devices for engineering development and test applications. Key features include:
• Data traffic from all user serial ports is serviced by a single TCP/IP session or the local
Master serial port. At any given time, only one user serial port is active for exchanging
data with the TCP/IP session or a local Master serial port. Data traf fic on inactive ports is
not buffered and data is lost.
• Local console port access: offers data rates from 2400 to 115200 bits/seconds and
optional hardware handshaking (CTS/RTS).
• Local Master Port access: offers data rates from 2400 to 115200 bits/second and
optional hardware handshaking (CTS/RTS). There are two operation modes for the port:
Console Transparent Mode and System Control Mode.
• Three user privilege login levels: The Administration level manages system
configuration and unconditional access to all power outlets and all serial ports. The User
level allows each user to reserve and manage his/her own ports, as well as to change most
of system configuration settings. Anonymous users are able to view all settings and
operate unreserved power outlets and serial console ports.
• User name and password for each port: Each port is user name and password protected.
• Line commands or menu configuration controls: Menu table operation offers
user-friendly operation methods that are used for changing system configurations,
viewing run time statuses, and issuing controls. Line commands provide quick and easy
operations.
• Network Access Filtering and Blocking: When the system connection is established
through a TCP/IP network, you can setup up the system to block or permit an IP address or
a group of IP addresses. This is done by filling an ACL (Access Control List) data entry
table. The default setting is ACL off, which means all IP accesses are welcome.
Synaccess Networks, Inc. www.synaccess-net.com
(760) 930 – 0473 Page 5 of 46

User’s Manual
• Telnet access: Remote access the system over a TCP/IP network for configuration and
control of the systems.
• Out of band Modem access interfacing: Control and configure the system via a
telephone line. Optional custom Modem AT command string to the Modem.
• HTTP web access: Embedded web server provides secured user name and password
authentication. The operations are easy and friendly, utilizing tables and graphical icons.
Download SNMP MIB files for convenience, or view an online help manual.
• SNMP MIB capability: An SNMP (Simple Network Management Protocol) agent is
integrated in the system for an exchange of management information between the system
and network devices.
• POP/SMTP Emailing with SMTP Authentication capability: A user can send control
commands or send user data to user console port via emails. Command execution reports
are replied for each command email received. SMTP user name and password are
protected through authentication process.
• SNMP Trap for sending logging message: The Trap is used to asynchronously report
events to the NMS. It forwards command execution information to the remote Trap
logging receiver.
1,2 What you can do with the system:
• Exchange user data transparently between one of the user serial console ports and the
Local Master serial console port, a remote Telnet terminal, or via an external Modem
device.
• Remote control and interact with user equipment anywhere beyond LAN. Via emails,
you are able to manage NC systems or user communication equipment power sources
when LAN access is impossible. Via emails, you can forward user data to communication
equipment. Reply emails are sent after the system intercepts incoming emails so that you
are informed with the operation status. Reply emails may also contains captured user
equipment console data (20 seconds aperture and up to 4 k bytes buffer) so that you can
interact with your systems.

2 Access to the System
2.1 Factory Default Settings:
The system is shipped with Factory Default settings. The default settings for the Local Master
serial port are: 9600, 8 data bits, no parity, 1 stop bit, and no hardware handshaking (Flow
Control). The default Administrator’s login name “admin” and the default password is “admin”.
All existing user accounts are erased if the system is recovered to the default settings. All user
console ports are set to the same parameters as the Local Master Port.
There are two ways to restore the system to the Factory Default settings. The first method is to
press a push-button switch located on the front panel for 1 second. The second method is to select
"Reload Factory Defaults" from the Main Menu. The Main Menu can be viewed by running a
terminal emulation program such as Window’s Hyper Terminal or Telnet.
Upon the system startup, the terminal screen displays the following screen, as shown in the Figure
5.
If you do not see the screen as shown in the Figure 5, it is likely that the system is not in the
default state. Otherwise, your connection to the Local Master port is established.

User’s Manual
2.2 User Privileges and Port Reservations:
All user levels, including anonymous (visitor), are able to access the system via a serial
connection from your work station to the Local Master port, or via a Telnet session from your
work station.
• Administration Login:
There is only one Administration account on the system. The default name is “admin”
and default password is also “admin”. The default name and password may be changed.
If you login at Administration level, you are able to remove or change existing user
accounts, take over power outlets or user serial console ports and change system settings.
• User Login:
At user login level, you are able to reserve power or console ports for your applications if
they are “open”, as well as make system configuration changes. At this login level, you
are not able to access other user reserved console ports.
• Anonymous(Visitor) Access:
If you have no account established on the system (as an anonymous user), you are only
able to view the system configuration settings and operate unreserved serial console ports.
2.3 Local Master Port Access:
The Local Master Port operates in two modes:
1) Console Port Transparent Mode: The Local Master Port and an active user port exchange
user data, as if the master port were directly connected to a user serial console port.
2) System Control Mode. A NC system enters control mode if the first letter f or a line entry
at the terminal is a predefined command prefix symbol, such as “/” (the default prefix letter). In
control mode, a user typed message at the master port terminal will not be forwarded to a user port.
You do not need to do anything to terminate the control mode because as soon as there is a new
line feed at the terminal, the system comes back to the User Port Transparent mode. However, if
the system enters the system configuration menu operation, no typed message will be sent to a
user console port until the menu operation is ended.
Note:
If the system is in Console Port Transparent Mode, there are no local echo characters on your
terminal because they are forwarded to user equipment that is connected to a user console port. It
is up to the connected user equipment how to respond to the messages you enter.
To access and configure the system from the master port, you need to connect a RS232 port from
your work station to the Local Master Serial Port. Then run a terminal emulation program (such
as Window’s Hyper Terminal) on your computer.
Synaccess Networks, Inc. www.synaccess-net.com
(760) 930 – 0473 Page 11 of 46
Page 12
User’s Manual
1) Connect the system’s Local Master Port (DCE) with a straight DB-9 type cable, if your
work station is equipped with a DTE part.
2) Connect the system’s Ethernet port to your LAN, if you intend to use the network port.
3) Turn the system power on.
4) At the terminal emulation program, type the “/setup” command to start the system setup
process. Type “/help” for help information.
5) The system has DHCP enabled, as a default setting. Network connectivity parameters are
displayed at the startup screen. If the system does not get a DHCP offer, the system falls
back to default static network settings. You can alter the default network settings to fit
your need.
6) Use the command “/ping” to verify your connection. If a network connection is
established, you are able to use Telnet, Web Browsing, Emailing and SMNP.
2.4 External Modem Access:
With this access method, an RS232 port on an external Modem device is connected to the Local
Master Port. Typically, a Modem device is equipped with a DCE (Data Communication
Equipment) terminal connector. Since the system’s Local Master Port and Modem device ports
are not complementary (both are DCE ports); you need to use a NULL Modem cable with both
male connectors.
Figure 6 - External Modem Connection
2.5 Network Access Control List (ACL):
ACL feature is used for controlling client IP addresses to access the system. You can block or
permit an IP or a group of IP addresses by filling the ACL data entry table. The default setting for
ACL is off, which means all IP accesses are welcome.
The filtering scheme is as followings:
1) A client IP is filtered through 6 masks: from 1 to 6.
Synaccess Networks, Inc. www.synaccess-net.com
(760) 930 – 0473 Page 12 of 46
Page 13
User’s Manual
2) Higher mask number has higher priority. If an IP is blocked by Mask 3 and then enabled
by Mask 4, the result is the IP is permissible.
3) A dotted value in a Mask is either 255 (which Permits or Blocks a whole range of the byte)
or a specific value from 0 to 254 (which Permits or Blocks that specific value).
4) If you enter the ACL data with unintended values that block your current access to the
system, you must use local RS-232 connection to disable the ACL, and then re-establish
the network connection.
Examples:
Only Permit 192.168.5.100 & 192.168.5.105. Block all other IPs.
Define Mask 1 to Block mode: 255.255.255.255. // Block al
Define Mask 2 to Permit mode: 192.168.5.100.
Define Mask 3 to Permit mode: 192.168.5.105.
Define all other Mask to Don't Care mode.
Only Permit 192.168.x.x.
Define Mask 1 to Block mode: 255.255.255.255. // Block all IPs
Define Mask 2 to Permit mode: 192.168.255.255.
Define all other Mask to Don't Care mode.
Only Block 192.168.5.100 and block 10.10.x.x.
Define Mask 1 to Block mode: 192.168.5.100.
Define Mask 2 to Block mode: 10.10.255.255.
Define all other Mask to Don't Care mode.
2.6 Telnet Access:
With Telnet access, you are able to communicate with an active user serial console port and
exchange user data as if you were directly connected to the port. You are also able to send control
commands to the system when the first letter of a line entry at Tenet terminal is a predefined
command prefix letter, such as “/” (
the default symbol). Operation of on a Telnet terminal is
almost identical to the access method via Local Master Serial Port. You need to make sure that
Telnet access is enabled, as a default setting. If the access is not enabled, please refer to Section
“Using Configuration Menu” to change the setting.
Before you start the Telnet application, you need to obtain the actual IP address for the system.
The system displays network connectivity information at system startup terminal when your work
station is connected to the system’s Local Master Serial Port. Please refer to “TCP/IP Network
Configuration” section of this document for information about
on how to setup the network
parameters.
Once the network connection is established, at your work station prompt, you need to enter:
telnet ip_addr
The telnet terminal screen will display the following message once it starts, shown in Figure 7.
You need to set a Telnet session on your work station to Local Echo Off mode. The NPC-48 or
NPC-22 does not echo user data locally on the Telnet session. It is up to the connected user
Synaccess Networks, Inc. www.synaccess-net.com
(760) 930 – 0473 Page 13 of 46
Page 14
User’s Manual
communication equipment, which usually sends responses while receiving data from its serial
console port. However, once the system is in System Control Command mode, the system starts
to echo user’s typing on the Telnet terminal.
Telnet session permits an anonymous user who may only to view the system settings and operate
unreserved power outlets and user serial console ports. Please refer to section 2.2 “User
privileges and Port Reservations” for further information.
• Only one Telnet session may be active at the time. Telnet sessions will be refused by the
system if it already has a Telnet session active.
• A Telnet session remains active for 10 minutes if it is in idle state.
• Telnet access methods can be enabled or disabled using the System Access Setup Menu.
• To terminate an active Telnet session, use the command “/logout” at the terminal. If you
are at a serial port terminal and notice that the terminal is disabled because it is taken o ver
by a remote Telnet session, use the command “/telnetend” at the serial console terminal to
terminate the Telnet if you need to do so.
Figure 7 - Telnet Session Startup screen
2.7 Web Access:
You need to obtain the system IP address before starting web access to the system. Please refer to
the Telnet Access section for methods to get the system IP address. You also need to make sure
that web access is enabled, as a default setting. If the access is not enabled, please refer to Section
“Using Configuration Menu” to change the setting. Start a Web browsing application program
such as Window’s Explorer and enter “http://ip_address“in the address field.

2.8 Email Access:
To establish this access method, the system’s network connection is already established. There
are two tasks that email access is capable of handling: executing NC system controlling
commands, and forwarding user’s data to an active user console port. The system sends a reply
email with command process status or/and captured user equipment console port data (20 seconds
aperture and up to 4 k bytes buffer) if an email is intercepted. See Section 4.4 for more
information about how to setup email accounts.
Figure 10 - Email Access - Sending Command from Hotmail Web Site
2.9 SNMP Information:
Applications such as an NMS (Network Management System) or an SNMP browser can
exchange information with NC systems. SNMP is disabled with the default setting.
The information managed by an SNMP daemon on the system can be obtained using SNMP
requests from a remote work station. An SNMP Get/Get Next request fetches the value of a single
variable or a set of variables. An SNMP Set request modifies the value of a variable.
You need to know the name of a variable before your can fetch or modify a variable's value. A
variable’s symbolic name is mapped to a numeric name, which is referred as OID.

The MIB (Management Information Base) is a text file describing the internal objects the SNMP
agent can display, monitor, and/or modify. Each MIB object is the system variable that has name
and an OID, as shown in Figure 11. You need the MIB file to properly configure the SNMP client
("manager") for server monitoring. To get a copy of the MIB file, please use a web browser to
access NC systems. Open the TCP/IP Network Configuration Menu and then click the button
“Get SNMP MIB File” to download the MIB file that is stored in the system’s memory.

3 Using Control Command
A NC system provides command line options for viewing or changing system configuration and
operation status. In addition, by using the control command option, users are able to create script
files for equipment test and control automation.
Control commands are applicable to the connections between your work station and Local Master
Serial Port or a Telnet session.
Some of the control commands are also applicable to Emailing controls. Besides sending
commands using Email, user data can be forwarded to a user console port. See related sections
for more detailed information about how to setup email accounts.
Once the system starts or a Telnet session is open, you are ready to send control command to the
system. Type command “/help” to have a complete list of available commands, as shown in
Figure 12.
All login levels including anonymous users are able to use the command line option. However,
the actual command executions are based on your login level. For example, if you are an
anonymous user, you are not able to reserve or un-reserve serial console ports or power outlets. If
you login at Administration level, you are able to operate any serial ports and power outlets,
reserve or unreserved
for a complete description of user privileges.
Note:
• A control command to the system proceeds with a prefix letter. The prefix letter must be
the first letter on a line entry. If both conditions are not met, the letters being typed are
forwarded to an active user serial port without local terminal echo. The default prefix
letter is "/". It may be changed if the prefix has a conflict with your applications.
• If your entry at the terminal is not a control command, your entry will be simply
forwarded to a current active user serial console port. Local Master Port and the user
console port is transparently sending or receiving user data. Your entry (typing) is not
echoed on the terminal screen. If you do NOT have access to a user serial port, an
unauthorized access error message is displayed while you are typing at the terminal.
• If you use Emailing access method, all commands list in Figure 12 are email-able.
However, some of commands do not have actual meanings such as the command “help”
any ports or outlets even if they are reserved by other users. See Section 2.2

or “date”. Via Emailing, command executions are subject to the same privilege rules
discussed in Section 2.1.1. Reply emails will be sent for indication of command execution.

4.4 More about Emailing Access:
4.4.1 Sending Control command to the system:
There are two tasks the system executes using the Emailing access method. The first task is to
send control commands such as controlling the power outlet. The second task is to send data to the
user serial ports. Control commands are placed in the em ail subject field, while user data to a user
serial port is placed in the email body.
A control command in the subject field has the following format:
&SysName&userName&password &Command&
where “SystemName” is a user defined system or device name; “username”and “password” are
valid user account name and password; and “command” is the actual system control command.
For example, an email subject “&mySite3&johnW&123456&sset 2&” will select user console
port 2 as the active port. The system is defined as“mySite3”. The user name is “johnW” and
password is “123456. Figure 10 shows an example of sending a control command email from
Microsoft Hotmail to a POP email recipient
test2@synaccess-net.com.

Synaccess Networks, Inc. www.synaccess-net.com
(760) 930 – 0473 Page 32 of 46
Page 33
User’s Manual
Before a command is executed, a confirmation reply email is sent. The destination of the replying
email address is already defined in the Network Configuration Table. Figure 21 shows a reply
email is received and displayed at “hotmail” web site.
Figure 21 – Reply Email Before a Control Command Is Executed
A control command is not executed if the system name does not match, user name does
not exists, or the name does not have the privilege to operate the designated serial console
port or power outlet port, or if there is a command syntax error. If this happens, a reply
email is sent to indicate the problem of the command, as shown in the Figure 22.
Figure 22 – Reply Email Indicating System Name Mismatch Error
Helpful Info:
• Use the command “/emailvbs x” to set to mail verbose mode. In verbose mode, the system
displays detailed information while sending and receiving emails. It is helpful while you
are setting up your email accounts.
“/emailvbs 0” turns the verbose mode off.
“/emailvbs 1” sets the system to level 1 verbose mode, in which high level emailing

“/emailvbs 2” sets to the system to level 2 verbose mode, in which detailed emailing
activities are displayed.
• Use command “/emailget” to check incoming emails immediately.
• Use command “emailsend” to send a test mail immediately
4.4.2 Sending Data to User Serial Console Ports:
The user data is placed in the email text body. Each line of the user data entry is braced
with the symbol “&”, such as: &my line 1 message&. The number of characters for each
line is limited to 200 characters. The maximum number of message lines is limited to 50.
For example, to send user data to serial port 2, enter the control command in an email
subject field:
&mySysName&myName&sset 2&
Then enter user data in an email body field:
&kill 45667 &
& lprint logfile &
Any messages that are not braced within “&” are not forwarded to user serial console port.

The system supports the following baud rates: 2400, 4800, 9600, 19200, 38400, 57600
and 115200.
It is strongly recommended that Master port and a user serial port have the same data rate
while exchanging data between them so that data loss is eliminated. If you must run both
ports using different baud rates, Flow Control (hardware handshaking) should be enabled
on all connected serial console ports.
Please also note that when Telnet access is used for exchanging data between the system’s
Ethernet interface port and user communication equipment, without enabling flow control,
