Chapter 5. Command-line configuration

It is normally simple to configure your Serial Server / 72-hour UPS using DeviceInstaller and the web interface. If, for any reason, this is not convenient, the unit can also be configured using a menu system accessed via the auxialiary serial port. A terminal emulator, such as Scream or PuTTY (for Windows) or minicom (for Linux) is required.

5.1 Getting started

5.1.1 Emulator settings

The terminal emulator should be configured for:

5.1.2 Connecting

With the power supply turned off, connect the cable between the Serial Server / 72-hour UPS and the power supply, then connect the auxiliary port to the PC running the terminal emulator using a standard serial cable. Start the emulator and configure it as in the preceding section.

Hold down the key in the emulator and, while keeping it held down, turn on the power supply to the Serial Server / 72-hour UPS. After a delay, the MAC address will be displayed. Press “Enter” and the Lantronix module will display a set-up menu, as shown below (details may vary):

It is normally advisable to reset the unit to its factory defaults by selecting option from this menu.

5.1.3 Using the menu

Throughout the configuration interface, the user is prompted for a series of configuration settings in turn. The current value is always offered as a default and this can always be selected by pressing the Enter key. After all the settings for any given section are configured, the user is returned to the top-level menu, as shown above.

No changes to settings will take effect unless option is taken afterwards.

5.2 Configuring serial channel 2

Serial channel two is connected internally to the DATA IN port and is used for all data transmission when the unit is connected via a network.

The factory defaults for the serial settings for channel two do not provide the most efficient Ethernet utilisation and should be changed: the FlushMode should be set to F7. If a non-standard baud rate is desired, it should also be configured at this point. (The same baud rate must then be configured in the digitiser or digital instrument, typically by using the BAUD command from the digitiser's command line: see the relevant manual for more details.)

To be sure of the correct configuration, first select option from the top-level menu to restore factory default settings. Next, select option from the top-level menu and, if necessary, enter the chosen baud rate at the first prompt; key “Enter” at the next prompts, retaining the default settings, until prompted for FlushMode. Enter F7 at this prompt and then key “Enter” at the remaining prompts.

5.3 Configuring the network interface

To configure the network (Ethernet) interface, select option from the top-level menu. You may be prompted for the network mode: in this case, select for wired only.

You will next be prompted for the IP address, as four separate values. If you wish to use DHCP, enter for each of these values; if not, enter the desired static IP address.

If your network uses a router, enter at the “Set Gateway IP Address” prompt: you will be prompted to enter details of your network's default router. If you do not use a router or do not wish to route packets from the CD24, enter at this prompt.

The following two questions allow you to configure a netmask and a DNS server, if you wish. Entering at the netmask prompt will result in the default netmask being signed. This is based on the IP address according to the traditional “classfull” addressing scheme.

In the example above, a default netmask of 255.255.255.0 will have been assigned because addresses beginning 192 are in class C.

5.4 Saving your settings

Once all desired configuration changes have been made, enter at the top-level menu in order to 'save and exit'.
