Operating

2 Operating

2.1 Operating the device directly

Port Switching

The current status of the output is indicated by the color of the LED. Red indicates that

the output is off, green shows that the output is on. On the device are the buttons "se-

lect" and "ok". If you press "select", you can select the following modes one by one:

1. At first, all LEDs flash green. If you press the "Ok" button for 2.5 seconds, all ports

are switched on. (If all ports are switched on, this is skipped).

2. After that, all LEDs flash red. If you hold the "Ok" button for 2.5 seconds, all ports

will be switched off. (If all ports are switched off, this will be skipped).

3. If you press "Select" again, the LED for the first output starts blinking, i.e. the output

is selected. Press "Select" again to select the next output. If you keep the "Ok" but-

ton pressed for one second, the state of the selected output will be toggled.

You can switch off in the front panel configuration that all ports with the modes

1 and 2 can be switched by pushbutton.

Status-LED

The Status LED shows the different states of the device:

·red: The device is not connected to the Ethernet.

·orange: The device is connected to the Ethernet and waits for data from the DHCP

server.

·green: The device is connected to the Ethernet and the TCP/IP settings are alloc-

ated.

·periodic blinking: The device is in Bootloader mode.

Operating

2.2 Control Panel

Access the web interface: http://"IP-address" and log-in.

The web page provides an overview of the switching state, as well as the external

sensor, provided that it is connected. When a single port is clicked at the Expert Net

Control 2302, a panel with buttons to control a single port appear:

The Port icon is green when the relay is closed, or red in the open state. An additional

small clock icon indicates that a timer is active. Timer can be activated by delay, reset

or batch mode.

An activated Watchdog is represented by an eye icon. An "X" means, that the address

that should be observed, could not be resolved. Two circular arrows show a booting

status.

Operating

The ports can be switched manually with the "On" and "Off" buttons. If the port is

turned on, it can be turned off by pressing the "Reset" button, until after a delay it turns

itself on again. The delay time is determined by the parameter Reset Duration, which is

described in the chapter "Configuration - Output Ports ". The "Close" button dis-

solves the panel again.

Batchmode

Each individual port can be set for a selectable period of time to the state "switch on"

or "switch off". After the selected time they are automatically switched to the second

preselected state.

Optionally the device can be switched via a Perl script or external tools like wget. More

information is available on our support wiki at www.gude.info/wiki.

The website contains a status overview of all passive signal inputs, the time since the

last change, and a counter of switching changes. The name and text for a logical state

of each input can be configured in the chapter Configuration-Input Ports .

2.3 Maintenance

The actual device generation with IPv6 and SSL allows all maintenance functions in

the web interface to be carried out on the Maintenance Page .

Maintenance in the web interface

The following functions are available from the maintenance web page:

·Firmware Update

·Change the SSL certificate

Operating

·Load and save the configuration

·Restart the device

·Factory Reset

·Jump into the Bootloader

·Delete the DNS cache

Upload Firmware, Certificate or Configuration

On the Maintenance Page , select the required file with "Browse .." in the sections

"Firmware Update", "SSL Certificate Upload" or "Config Import File Upload" and press

"Upload". The file is now transferred to the update area of the device and the contents

are checked. Only now, pressing the "Apply" button will permanently update the data,

or abort with "Cancel".

Only one upload function can be initiated with a reboot, eg. you cannot transmit

firmware and configuration at the same time.

If after a firmware update, the web page is not displayed correctly anymore, this

may be related to the interaction of Javascript with an outdated browser cache. If a

Ctrl-F5 does not help, it is recommended that you manually delete the cache in the

browser options. Alternatively, you can test start the browser in "private mode".

During a firmware update, old data formats are sometimes converted to new struc-

tures. If an older firmware is newly installed, the configuration data and the energy

meters may be lost! If the device then does not run correctly, please restore the factory

settings (e.g. from the Maintenance Page ).

Actions in Bootloader mode

If the web interface of the device is no longer accessible, the device can be put into

Bootloader mode (see chapter Bootloader activation ). The following functions can

be executed using the GBL_Conf.exe application:

·Set IPv4 address, net-mask and gateway

·Turn HTTP password on and off

·Turn IP-ACL on and off

·Factory Reset

·Jump into the bootloader (can be switched on and off)

·Restart the device

For devices with relays, entering or exiting the bootloader mode does not change

the state of the relays as long as the operating voltage is maintained.

The GBL_Conf.exe program is available free of charge on our website www.gude.info

and can also be found on the enclosed CD-ROM.

Operating

Interface GBL_Conf

To check the network settings with GBL_Conf.exe, start the program and choose "All

Devices" in the "Search" menu. From the list select the appropriate device. The lower

part of the left half of the window now shows the current network settings of the device.

If the IP address is displayed with the default settings (192.168.0.2), either no DHCP

server is present on the network, or there could be no free IP address assigned to it.

·Activate the Bootloader Mode (see Chapter Bootloader Mode) and choose in menu

"Search" the item "Bootloader-Mode Devices only"

·Enter the desired settings in the edit window and save them with "Save Config".

·Deactivate the boot loader mode for the changes to take effect. Select again "All

Devices" in the "Search" menu of GBL_Conf.exe.

The new network configuration is now displayed.

Factory Reset

The device can be reset to the factory default via the web interface from the Mainten-

ance Page or from the Bootloader mode (see chapter Bootloader activation ). All

TCP/IP settings are reset in this operation.

If a unit is set to factory defaults, an uploaded certificate or updated firmware will

be preserved.

2.3.1 Maintenance Page

This section provides access to important functions such as Firmware Update or Re-

start Device. It is advisable to set an HTTP password for this reason.

18 21

Operating

Firmware Update: Start a firmware update.

SSL Certificate Upload: Saves your own SSL certificate. See chapter "SSL " for the

generation of a certificate in the right format.

Config Import File Upload: Loads a new configuration from a text file. To apply the new

configuration, a "Restart Device" must be executed after the "Upload".

Config File Export: Saves the current configuration in a text file.

Saving the configuration should only be carried out in an SSL connection, since it

contains sensitive password information (even if it is encrypted or hashed).

Restart Device: Restarts the device without changing the status of the relays.

Some functions such as a firmware update or changing of the IP-address and

HTTP settings require a restart of the device. A jump to the boot loader or a restart of

the device lead by no means to a change of the relay states.

Restore Fab Settings and Restart Device: Performs a restart and resets the device to

factory default .

Enter Bootloader Mode: Jumps into bootloader mode, where additional settings can be

made with GBL_Conf.exe.

Flush DNS Cache: All entries in the DNS cache are discarded and address resolutions

are requested again.

Config/Status View: status.html: Displays the status.html page with the JSON data.

Operating

Config/Status Download: export.json: Direct file download of JSON data from

status.hml.

2.3.2 Configuration Management

The device configuration can be saved and restored in the maintenance area .

The "Config File Export" function can be used to save the current configuration as a

text file. The syntax used in the configuration file corresponds to the commands of the

Telnet console. If the configuration of a device is to be restored from a text file, load

the file with "Upload" and restart the device with "Restart Device".

Saving the configuration should only be carried out in an SSL connection, since it

contains sensitive password information (even if it is encrypted or hashed). For the

same reasons, it is advisable to carefully handle the generated configuration files when

archiving.

Editing the configuration file

It is possible to customize a saved configuration file with a text editor for your own

needs. For example, one scenario would be to use a script language to automate the

creation of many customized versions of a configuration, then equip a large number of

devices with an individualized configuration. Also Upload and restart with CGI com-

mands can be done in scripting languages. With use of the comment sign "#" you can

quickly hide single commands or add personal notes.

If you modify a configuration file manually, it is not always clear which limits are allowed

for parameters. After uploading and restarting, commands with invalid parameters are

ignored. Therefore, the generated configuration includes comments describing the

boundaries of the parameters. Where "range:" refers to a numeric value, and "len:" to a

text parameter. E.g:

email auth set 0 #range: 0..2

email user set "" #len: 0..100

The command "system fabsettings" from the beginning of a generated configuration

file brings the device into the factory state, and then executes the individual commands

that modify the configuration state. It may be desirable to make the changes relative to

the current configuration, and not out of the factory state. Then the "system fabset-

tings" should be removed.

No output of default values

The configuration file contains (with exceptions) only values which differ from the de-

fault. The command "system fabsettings" (go to the factory state) from the beginning of

a generated configuration file should not be removed, otherwise the device can get in-

completely configured.
