Microtronix Access X.25–TCP/IP Gateway
1 Overview
The Microtronix Access X.25–TCP/IP Gateway provides conversion between X.25 and TCP/IP devices, or X.25 encapsulation over TCP (XOT). In addition, raw synchronous and serial terminal servers may be configured.
A web interface allows for configuration and monitoring from any Internet browser, and telnet/SSH servers allow for connecting to the command line interface for additional management.

Model 4002-N44-RM
The model name and serial number are printed on the label located on the bottom of the unit.
The following sections describe the each attributes and function of each interface type.
1.2 WAN interface
WAN ports support RS232/V.24 with speeds up to 128 Kbps, and V.35, X.21, RS530, RS449/V.36 interface types with speeds up to 10 Mbps, in a standard DB25F DCE connector. The ports may be used for:
● X.25
● Synchronous Server
● Serial Terminal Server
The 1000 models have one WAN interface that doubles as the boot console, and the 4002 models have two WAN interfaces with one that doubles as the Console port. See the notes under Console interface below.
1.3 Console interface
The Console/WAN port may be used for:
● X.25
● Synchronous Server
● Serial Terminal Server
● System console port for configuration and monitoring
In addition, the Console/WAN port serves as the console for the boot program and operates in RS232 asynchronous mode during boot up. The boot command line interface may be invoked for system management and emergency IP address recovery by entering a password during a 10 second interval after power up.
1.4 Network (Ethernet) interface
The RJ45 NETWORK interface is 10/100 Ethernet with full auto-detection, supporting a rich set of standard IP protocols.
1.5 USB interface
The USB 1.1 type A host port supports additional serial interface or storage devices:
● USB serial adapters (FTDI chipset only) for up to 8 additional Terminal Server interfaces
www.microtronix.com 5
Microtronix Access X.25–TCP/IP Gateway
● USB flash drive for storing and moving files
The 4002-S04 and 4002-N04-RM models may be specially ordered with an internally mounted USB flash drive with no external USB connector.
The 4002-N44-RM models have an internally mounted USB 4-port serial expansion card.
2 Package Check List

3 Quick Start Guide
Configuration of the Access Gateway will require a PC or laptop with standard Internet browser like Internet Explorer or Mozilla Firefox. Optionally, a serial COM port (or USB serial adapter) on the PC with a terminal emulator application may be used to connect to the Console port.
3.1 Installation
1) The Access Gateway may be placed on a shelf in a rack, or mounted using a rack mount kit.
2) Connect to the IP network through the RJ45 10/100 Network port. To connect directly to the PC, use the Ethernet cross cable (red).
3) Optional: Connect the Console port to the PC using the Console Cable. Refer to the “Console Port” section below for instructions.
4) Connect AC/DC power adapter and AC power cord (or attach the -48VDC power cord)
5) Wait 30 seconds for the boot process to complete. The RUN led will start to blink.
3.2 Ethernet / IP Port
The Ethernet port can be used for initial configuration. The default IP address of the Access Gateway is
10.1.1.240/24. To connect via IP, set the PC's IP address to 10.1.1.200, and subnet mask to
255.255.255.0 (10.1.1.0/24).
3.2.1 Web Interface (htttp / https)
The Access Gateway has a web-based server for configuring and monitoring. Use any Internet browser to connect to the web interface. Login is required with username “admin”, and default password “admin”.
3.2.2 Terminal Interface (telnet / ssh)
The Access Gateway will also accept Telnet or ssh client connections for advanced monitoring and troubleshooting. The username is “root”, and the default password is “f0adA” (0=zero) for privileged access, and “admin”, “admin” for non-privileged access.
3.3 Console Port (Optional)
The Console port offers system control access during the boot-up process. Boot messages will be displayed if a PC COM port is connected using the Console Cable, and a terminal emulator like “putty” or “HyperTerminal” is set for 9600-N-8-1.
3.3.1 U-Boot Command Access
After power up, there is a 10 second delay that allows U-Boot command access:
Autoboot in 10 seconds (Enter password to stop)...
if the password “foad” is typed while the message is displayed, the U-Boot prompt “A4K:>” will indicate command readiness.
3.3.2 Setting Default IP Parameters
The default IP network parameters may be modified or added here as an alternative to the configuration via the web interface. Enter the following commands to change the default IP address, netmask, default gateway (if needed), and optionally a new system “hostname”
set ipaddr 10.1.1.240 set netmask 255.255.255.0 set gatewayip 10.1.1.1
www.microtronix.com 7
Microtronix Access X.25–TCP/IP Gateway
set hostname MYNAME save boot
These defaults will remain in effect until again changed again in U-Boot, or explicitly changed via the Ethernet configuration page in the web interface.
3.3.3 Emergency IP Address Recovery
The u-boot console may be used to recover a forgotten IP address. While in the U-Boot console, the default IP address and other parameters may be displayed:
print ipaddr print netmask print gatewayip
If the default values are not in current effect, they may override the system-defined values temporarily by setting new default values (if desired) and entering the U-Boot commands:
set runlevel 2 save boot
When the system starts up, it will be using the default IP address information, and should be reachable on that network. Browse into the web interface and access the Ethernet page to view the “forgotten” values. Restart the system to get the U-Boot console, and reset run level:
set runlevel save boot
The system will restart with the system-defined values.
3.3.4 System Firmware Updates
The u-boot console may also be used in conjunction with Microtronix support for applying firmware updates, and emergency IP address recovery.
To apply firmware updates:
1) Obtain the kernel image (uImage) and/or filesystem image (jffs2.img) files from Microtronix
2) Start a tftpd server on the PC or an available file server
3) Place the file(s) in the tftpd default directory on the PC or server
4) Enter the PC or server IP address (example 10.1.1.200) using the u-boot commands:
set serverip 10.1.1.200 save
5) Load the new kernel image:
run updatekernel
6) Load the new filesystem image:
run updatejffs2
7) Start the system by re-applying power or typing the “boot” command.

3.4 Configuration Web Interface
The default IP address of the Access Gateway is 10.1.1.240. The PC used to access the web interface must be configured (temporarily) for an address in the same subnet, for example, 10.1.1.200. Connect the PC to the same LAN, or temporarily use the red Ethernet crossover cable to connect directly to the Access Gateway.
Open the web browser on the PC, and enter http://10.1.1.240 in the URL field. When prompted by a popup window, login using default user name: admin, and password: admin.
The home page will be displayed with the main menu down the left hand side.
The Access Gateway can now be configured by selecting the main menu items. Each page has a Help button in the upper right corner for viewing additional information specific to the current page.
Note: If using Windows Internet Explorer, Compatibility View may need to be enabled. This can be
done by clicking on the “broken page” icon in the address field of the address bar, or by adding the IP address using the Compatibility View Settings IE Tools menu.

3.5 IP Network Configuration
To create or modify the IP network parameters different than the default values defined in U-Boot , obtain the new IP address, network mask, and default gateway values. Follow this procedure only if you don't want the default values to be used in the running system.
From the main menu System section, select Ethernet to display the configuration form.
1) Modify the Hostname as desired.
2) Enter the new Default Gateway IP address, if needed.
3) Click on the Select button in the Ethernet Interfaces table corresponding to “eth0”.
4) Enter the new IP address and network mask.
5) Click the Apply button for the changes to be saved and to take affect.
Connect the Network port to the new network, if not already. Since the IP connection may be lost due to the change, the new address may need to be entered in the browser. The Ethernet configuration page displays the current status of the Ethernet interface.
For more information on additional network configuration, click the Help button on the page.
