2.1 Operating the device directly
Port Switching
The current switching state of the output is indicated by the corresponding plain text dis-
plays (port LEDs). If the green "on" LED is lit, the port is switched on, if the red "off" LED
is lit, the output port is switched off. The buttons "Select" and "Ok" are located on the
device. If you press "select", you can select the following modes one after the other (in
the front panel configuration you can deactivate the modes "All on" or "All off").
1. All on (PALL in the display): All LEDs flash green. If you press the "Ok" button for
2.5 seconds, all ports are switched on.
2. All off (PALL in the display): All LEDs flash red. If you hold the "Ok" button for 2.5
seconds, all ports are switched off.
3. If you press "Select" again, the LED for the first output starts flashing, i.e. the output
is selected. Press "Select" again to select the next output. Pressing and holding the
"Ok" button for one second will toggle the state of the selected output.
If the ports are already "All on" or "All off", the corresponding mode is skipped.
Display Information
If no port is selected manually, repeatedly pressing the "ok" button will show the IP-ad-
dress and the values of the external sensors on the display.
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 allocated.
·periodic blinking: The device is in Bootloader mode.
2.2 Control Panel
Access the web interface: http://"IP-address" and log-in.

Operating
The web page provides an overview of the switching state, energy measurement values,
as well as the external sensors, provided that they are connected. When a single port is
clicked 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.
In addition to the panel, the Expert Power Control 8316 shows the measured values of
the selected port:

15
Expert Power Control 8316 © 2022 GUDE Systems GmbH
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 de-
scribed in the chapter "Configuration - Power Ports ". The "Close" button dissolves
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.
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
·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
24
18

16
Expert Power Control 8316 © 2022 GUDE Systems GmbH
Operating
"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 firm-
ware 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 op-
tions. 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
·Allow jump from firmware to bootloader
·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.

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.
Changing the configuration with gbl_conf.exe is explicitly only allowed in bootloader
mode!
Factory Reset
The device can be reset to the factory default via the web interface from the Maintenance
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.

Operating
2.3.1 Maintenance Page
This section provides access to important functions such as Firmware Update or Restart
Device. It is advisable to set an HTTP password for this reason.
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 .

Operating
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.
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 archiv-
ing.
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 commands
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 ig-
nored. Therefore, the generated configuration includes comments describing the bound-
aries 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
18

20
Expert Power Control 8316 © 2022 GUDE Systems GmbH
Operating
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 fabsettings"
should be removed.
No output of default values
The configuration file contains (with exceptions) only values which differ from the default.
The command "system fabsettings" (go to the factory state) from the beginning of a gen-
erated configuration file should not be removed, otherwise the device can get incom-
pletely configured.
Configuration via Telnet
The configuration files can in principle also be transferred in a Telnet session, but then
the settings are changed during operation, and not completely when restarting, as it
would have been the case with an upload. It can happen that events are triggered at the
same time as the device is configured. One should therefore:
a) disable the function
b) completely parametrize
c) reactivate the function
An example:
email enabled set 0
email sender set "" #len: 0..100
email recipient set "" #len: 0..100
email server set "" #len: 0..100
email port set 25
email security set 0 #range: 0..2
email auth set 0 #range: 0..2
email user set "" #len: 0..100
email passwd hash set "" #len: 0..100
email enabled set 1 #range: 0..1
2.3.3 Bootloader Activation
The configuration of the device from the application "GBL_Conf.exe" is only possible, if
the device is in Bootloader Mode.
Activation of the Bootloader Mode
1) via push button:
·Hold both buttons for 3 seconds
2) or
·Remove the power supply
·Hold down the "Select" button. If the push button is recessed, use a pin or paper clip
·Connect the operating voltage
