• Twist lock power connector
• 10/100 Base-T Ethernet instead of 10 Base-T only
• Optional 4 port 10/100 switch (vs.optional 2 port 10-only Hub)
• 2 - 4 DB-9 Serial ports all on the front of the unit
• Serial port speed improved to 230.4 K Baud (Max)
• Increased surge/spike protection on serial ports

NDS/5000 Integrated Communications Servers

What is the NDS/5000?
Features and Benefits
Configuring the NDS/5000: Storing and Changing Settings
Possible Configurations for the NDS/5000 in a Networking Environment

The NDS/5000 family of remote communications servers connects to 10/100 Mbps Ethernet and provides eight or sixteen RJ-45 serial ports that are software selectable to RS-232, RS-422, or RS-485. The NDS/5000 uses the TCP/IP family of protocols to provide terminal connectivity and communications services in open systems environments.

Features and Benefits

The NDS/5000 offers the following features and benefits:

• Easy set up and configuration
• Open systems communications for multi-site data networks
• Can be used in a variety of data communications applications
• Reduces cost and complexity
• 8 or 16 RJ-45 serial ports
• 1 Switch with 4 ethernet ports, 1 port cross-wired for easy connection to another switch
• High-speed serial connections
• Software selectable RS-232, RS-422, or RS-485 modes on each port
• Operating system independent
• Complete remote diagnostics
• LEDs for each port, signaling port status and error conditions
• Industry standard interoperability
• Developer's API for custom, on-board applications and protocols
• Raw reverse telnet option so you can access ports without using special protocol or processing
• Standard lpd printing option that is efficient and easy to use
• Dial on demand to automatically dial and make a connection with a remote system
• Multiple services per port allows setting up both incoming and outgoing services on the same port
• ppp header compression
• Reverse telnet support for a variety of UNIX operating system

Configuring the NDS/5000

• If you are using Windows, you can install and use the NativeCOM software, setting the IP address as part of the configuration process. The NativeCOM software is provided free of charge with your Systech port server.
• assign the IP address using ARP on a host
• assign the IP address using a BOOTP server
• allow a DHCP server to assign the IP address

Session settings

When the NDS/5000 is booted, the configuration information that defines the operation of the NDS/5000 during the session (the active configuration) is loaded into memory from the current configuration database in flash memory. You can change any configuration setting in the active configuration. In addition, you can save the active configuration into the current configuration database (in flash memory) so that the changed settings will be available after reboot/restart.

When the NDS/5000 is delivered, the current configuration database contains factory default settings. In addition, a factory default configuration database (a copy of the current configuration database) is stored in flash memory. The factory default configuration database is stored as a backup configuration which can be restored into the current configuration database if necessary. If the NDS/5000 encounters an error condition while loading the current configuration database into the active configuration, it will load the factory default configuration database into the active configuration instead, in order to complete the boot. The status LED on the back panel will flash alternately yellow and green to indicate that a problem occurred and the factory default configuration was loaded.

• using the NDS/5000 command interface via a terminal connected to the NDS/5000; or
• using a web browser to connect to the IP address of the NDS/5000; or
• for Windows users, using the NativeCOM port redirector software developed by Systech and provided free of charge with the NDS/5000.

At any point, you can restore the factory default configuration settings.

Settings

Some of the commonly changed configuration items are.

Passwords

• User login
• Administrative

Networking

• Internet address
• Subnetwork mask
• Initial route list
• Host name list
• Domain name
• DNS server list

Asynch serial ports

• Service definition
• Speed
• Character length
• Stop bits
• Parity
• Input flow control
• Output flow control
• Inactivity timeout
• switch character
• dcd modem signal

Possible Configurations

Terminal dedicated to a host

Automatically connects a terminal to a host located anywhere on the network. Useful for applications that require a user's terminal to communicate with one and only one host computer, perhaps running a specialized application program.

Terminal for Rlogin/telnet using multiple sessions

Supports up to four sessions for each connected terminal.

Dial-in modem for telnet/rlogin or ppp/slip

Can dial-in and automatically start a slip, ppp, rlogin, or telnet session.

Dial-out modem (rtelnet)

Can access the modem for dial-out using telnet or using a reverse telnet connection and application program, such as terminal emulator, tip, cu.

ISDN terminal adapters

Can use ISDN terminal adapters instead of modems

Printing to a serial port

The NDS/5000 Series of Integrated Communication Servers provides LAN-attached serial port expansion, Ethernet switch, remote monitoring, and IP routing. The NDS/5000 uses industry standard TCP/IP, SLIP, and PPP protocols to ensure open-systems connectivity and flexibility for your demanding applications.

For applications deploying the NDS/5000 products to connect and network distributed serial devices at any number of remote locations, Systech ONDEMAND remote access and management software provides an ideal solution for cost effectively and securely managing and controlling these remote devices.

The NDS/5000 terminal server is bundled with Systech's industry-leading NativeCOM port redirection software, Remote Network Device Monitoring software, web browser interface, and remote diagnostics, and Modbus Gatewaysoftware, enabling serial-to-IP connections for Modbus TCP/IP clients and Modbus RTU devices.  NativeCOM simplifies installation and support and makes any Systech ethernet serial port (whether local or remote) appear as local to your application. Systech's Remote Network Device Monitoring software capability delivers the ability to manage, control, and share access to networks deploying Systech's serial-to-IP solutions through any Internet browser.

Each NDS/5000 RJ-45 serial port is software selectable to RS-232, RS-422, or RS-485 with no external cabling, saving you the cost and complexity of competitive solutions that offer a single physical interface.

For developers and OEMs with unique protocol conversion, monitoring, or reporting needs, Systech's Developer's API is available to create custom added-value applications.

For additional information, access Systech's on-line data sheet and documentation for the NDS/5000 serial device server product family. Two models are available as follows:

	Model	Serial Ports	Printer Port	4 Port Switch
	NDS/5008	8	Yes	Yes
	NDS/5016	16	Yes	Yes

The NDS/5000 as a terminal server:

The device is easily configurable through the it's built in web interface to automatically connect a terminal to a host located anywhere on the network or across the internet. Useful for applications that require a user's terminal to communicate with one and only one host computer, perhaps running a specialized application program. For Rlogin/telnet using multiple sessions, the NDS/5000 supports up to four sessions for each connected terminal.

The NDS/5000 as a console or device server:

The device is ideal for connecting to any serial device from a host server, multiple servers, or across a wide area network using telnet, raw TCP, or as virtual COM ports using the Systech NativeCOM software. The NDS/5000 is used in various point of sale and industrial applications.
