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 cor-
rect 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".

address assigned to it.
Configuration by Software
2.1
To view and change the network settings, you can use the program GBL_Conf.exe. The program is
available for free on our website www.gude.info and is also available on the accompanying CD-ROM.
You can also use GBL_Conf.exe to install firmware updates and trigger a reset to factory defaults.
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".

Use the "Configuration" Tab to enter the configuration menu.
Configuration - IP Address
2.2.1
Hostname: Here you can enter a name with up to 15 characters. This name will be used for registration
on the DHCP server. Special characters and umlauts can cause problems in the network.
IP Address: The IP address of the device.
Netmask: The network mask used in the network.
Gateway address: The IP address of the gateway.
Use DHCP: Select "yes" if the TCP/IP settings should be obtained directly from the DHCP server:
When the function is selected, each time the device powers up it is checked if a DHCP server is availa-
ble on the network. If not, the last used TCP/IP setting will be used further.
All IP changes will take effect directly, there is no need for a restart of the firmware.

Expert Sensor Box 7211/7212 Configuration
Configuration - IP ACL
2.2.2
Reply ICMP ping requests: If you enable this feature, the device responds to ICMP pings from the net-
work.
Enable IP filter: Enable or disable the IP filter here. The IP filter represents an access control for inco-
ming IP packets.
Please note that when IP access control is enabled DHCP and SNMP only work if the appro-
priate servers and clients are registered in the IP access control list.
IP Access Control List
The IP Access Control List (ACL IP) is a filter for incoming IP packets. If the filter is active, you can on-
ly connect to hosts and subnets whose IP addresses are entered in the list.
Examples:
Entry in the IP ACL
Meaning
192.168.0.123
the PC with IP Address „192.168.0.123" can access the device
192.168.0.1/24
all devices of subnet „192.168.0.1/24“ can access
If you choose a wrong IP ACL setting and locked yourself out, please activate the Bootloader Mode and
use GBL_Conf.exe to deactivate the IP ACL.

Configuration - HTTP
2.2.3
HTTP port: Here can be set the port number of the internal HTTP. Possible values ??are from 1 to 65534
(default: 80). If you do not use the default port, you must append the port number to the address with a
colon to address the device from a web browser. Such as: "http://192.168.0.2:800"
Enable auto refresh HTML: If this is activated, the information of the status page is automatically upda-
ted via http request (AJAX).
Require HTTP password: If desired, a http password protection can be enabled. In this case, an admin
password and a user password can be assigned. The password can have up to 15 characters. User
can log in by entering the user's password to query the status information and make changes to ports
(if applicable). Admins have the privileges of a User and can change the Configuration settings. In the
username field of the password input mask the names "admin" and "user" are supported. In the factory
defaults the password for the admin is set to "admin" resp. "user" for the user password.
If you have forgotten your password, please activate the bootloader mode and then turn off
the password prompt in GBL_Conf.exe.

Configuration - Sensors
2.2.4
Choose sensor port: Selects a type of sensor to configure it. The first digit "1" indicates the number of
the sensor port (only important for devices with more than one sensor port). This is followed by the sen-
sor name (eg 7002 for the hybrid sensor), a letter for the sub-type sensor and the changeable sensor
name. The sensor subtypes are defined as: "T" = temperature, "H" = humidity, "I" = sensor input.
Sensor Name: Changeable name for this sensor. Temperature and humidity can have different names,
even if they are from the same sensor.
Generate messages: Enables the generation of messages.
Maximum/Minimum value: Here you can choose whether, and at what Maximum/Minimum temperature
or humidity measurements limits the alerts are send via SNMP traps, syslog or email.
Hysteresis: This is the distance between the value that is signaling an overrun of a limit and the value
that signals an underrun of the same limit.
Min/Max measurement period: Selects the time range for the sensor min / max values ??on the overview
web page.
Hysteresis Example:
A Hysteresis value prevents that too much messages are generated, when a sensor value is jittering
around a sensor limit. The following example shows the behavior for a temperature sensor and a hyste-
resis value of "1". An upper limit of "50 °C" is set.
Example:
49.9 °C - is below the upper limit
50.0 °C - a message is generated for reaching the upper limit
50.1 °C - is above the upper limit
...

13
Expert Sensor Box 7211/7212 Configuration
49.1 °C - is below the upper limit, but in the hysteresis range
49.0 °C - is below the upper limit, but in the hysteresis range
48.9 °C - a message is generated for underrunning the upper limit inclusive hysteresis range
...
Configuration - Alarm Beeper
2.2.5
Enable Beeper: The unit has an internal beeper, that can be enabled for audible alarms.
Ampere Limit: Enter the limit for the current at which the beeper is to be activated.

Configuration - E-Mail
2.2.8
Currently, only SMTP servers are supported, that are offering no authentication (open-relay) or unen-
crypted authentication (PLAIN). An encrypted authentication to the SMTP server is not possible.
An experienced user can learn whether the desired SMTP server understands the PLAIN authenticati-
on, by sending the string "EHLO localhost" with Telnet to the server. Here's an example:
$ telnet smtp.1und1.com 25
Trying 212.227.15.129...
Connected to smtp.1und1.com.
Escape character is '^]'.

Protocols
3
SNMP
3.1
SNMP can be used to obtain status information via UDP (port 161). Supported SNMP commands are:
·GET
·GETNEXT
·GETBULK
·SET
To query via SNMP you need a Network Management System, such as HP OpenView, OpenNMS, Na-
gios, etc., or the command line tools of the Net-SNMP software.
SNMP-communities
SNMP authenticates requests by communities. A community is a string that acts like a password for a

16
Expert Sensor Box 7211/7212 Protocols
read or a write SNMP access. Since these passwords are sent unencrypted and are easily intercepted
with IP sniffers, it is recommended to use a safe network structure (DMZ) when security is required.
MIB
The values ??that can be read from the device or changed, the so-called "Managed Objects", are descri-
bed in Management Information Bases (MIBs). The MIB table is build of substructures that are called
OIDs (Object Identifiers). An OID number indicates the location of a value within the MIB tree. Each OID
may alternatively be referred to with its symbol name (subtree name).
SNMP Traps
SNMP Traps are system messages that are sent via the SNMP protocol to different recipients. SNMP
traps are triggered by the following events:
·Turning on the device
·Enable/disable of syslog in the configuration
·Exceeding of the max / min values ??of attached sensors
Syslog
3.2
Syslog messages are simple text messages that are sent via UDP to a syslog server. Under Linux,
normally a syslog daemon is already running (eg. syslog-ng), for Microsoft Windows systems some
freeware programs are available on the market. The syslog messages are sent for the following events:
·Turning on the device
·Enable/disable of syslog in the configuration
·Exceeding of the max / min values ??of attached sensors
