Firmware-Update
1.7
To perform a firmware update, the program GBL_Conf.exe and the latest firmware is needed.
Enable the bootloader mode (see Chapter Bootloader Mode)
Start GBL_Conf.exe
Select the device for which a firmware update is to be performed
Click "Program Device" and then select there "Firmware Update"
Specify the firmware file that should be uploaded
Upon completion of the update process, please start the new firmware of the device. You can do this
by simply leaving the bootloader mode.
A firmware update, unlike other functions, is not sent as a network broadcast. Therefore, the device
must have a valid IP address and a valid netmask before the firmware update. If necessary, please
correct the entries in GBL_Conf.exe in bootloader mode and save them with "Save Config".
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. Not always helps a Ctrl-F5, it is recommen-
ded that you manually delete the cache in the browser options. Alternatively, you can test start the
browser in "private mode".

Operating by Webinterface
2.2
Access the web interface: http://"IP-address" and log-in.
The website offers an overview of the port status, measurements and sensors, if they are connected.
Furthermore, there are buttons to control the state of the ports. 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 about configuration via web interface.
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.

Expert Power Control 8090 GSM Operating
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.
GSM
2.3
To use the GSM functions, there must be an activated SIM card in the SIM card slot located on the
front of the unit.
If the SIM card is inserted, and the device is enabled, the integrated GSM module searches automat-
ically for a connection to the GSM network. If this connection works, you can control and configure
the device via SMS or by call.
When operating via SMS, send defined SMS commands to the device. The device executes these
commands and confirms them with reply SMS.
When operating via phone call, you can perform commands by FreeCall, that allow the unit to per-
form preconfigured commands, when it is called from a particular phone number. There is no connec-
tion established and there are no call charges. Another possibility is the voice call. Here, the device
menu is operated using DTMF codes. This type of operation can also be carried out automatically.
Preparing for GSM operation
If you are using a new SIM card, please take note:
1. Preparing the SIM card
·If you are using a contracted SIM card, please start with step 2
·If you are using a prepaid SIM card, please take care:
oThere has to be a positiv balance on the card
oThe card has to be activated. New prepaid cards need some manual operation
at the start of usage. These requests have to be made from a user with a cell-
phone.
2. SIM-card pin code
·The device awaits the SIM card pin code 1234 first. Enter this PIN to the SIM card, by
using a cellphone. In case you are using another pin code, you have to configure the
EPC NET GSM before you activate the GSM part of the device! Otherwise this may
lead to a lock of the SIM card.
·You can disable the need to enter the PIN code on the SIM card with a mobile phone.
In this case the EPC NET GSM accepts the SIM card without checking the code.
3. Install SIM card
·Switch off the device or deactivate the GSM module. Alternatively, you can just turn off
the GSM module in the EPC NET GSM via software. Never install a SIM card, when
GSM module is active. Otherwise the SIM card may be destroyed.
·Release the SIM card holder by pressing the yellow button with a fine stick. Insert the
SIM card in the ejected plastic tray and slide it back inside until it stops.
4. Connect Antenna
14
Expert Power Control 8090 GSM Operating
·Take the GSM antenna from the box and screw it to the EPC NET GSM by turning
clockwise. It is enough to attract the connection hand-tight. Never use pliers to tighten
or similar to the antenna, thus inevitably destroying the antenna connection.
5. Activate the EPC NET GSM
·Power up the device. In factory default state, the GSM module is deactivated. This is a
security setting in delivery to avoid accidentally locking a SIM card with the wrong
code.
·Log in on the web interface.
·Switch to Configuration / GSM / SIM.
·Here the button "Enable GSM" is set to "No", that is the GSM module is turned off. Set
the button to "yes", then press the button "Apply" to transmit the data to the EPC NET
GSM.
·Wait some minutes, until the device has logged into the GSM. You can see the status
change from the flashing GSM status LED or in the web interface.
GSM Status LED
The GSM status LED displays different states of the GSM module.
LED off
GSM module is deactivated.
LED permanent red
