The »DevCon-Center« appliance
The Config Panel web application is integrated into various G&D devices. It provides
the graphical user interface to configure and monitor the devices.
Adding an DevCon-Center appliance to the existing G&D devices (with integrated
web application) adds up to a KVM system which enables you to centrally configure
and monitor the single devices.
Scope of delivery
1 × DevCon-Center
2 × power cable (PowerCable-2 Standard)
1 × service cable (USB-Service-2)
1 × manual »Installation Guide«
1 × manual »Config Panel« web application
ADVICE: The web application can be applied independently from the locations of
the devices connected to the KVM system.
NOTE: The scope of delivery includes rackmount sets (19" RM-Set-435-1HE) to
mount the devices into a 19” rack.

Installation
3· G&D DevCon-Center
Installation
Establishing a connection to up to two local networks
Network A: Insert a category 5 twisted pair cable (or better).
Network B: If you want to integrate the DevCon-Center appliance into another network,
insert the category 5 (or better) cable into this interface.
Connect the other end of the cable to the local network.
Establishing the power supply
Main Power: Insert the supplied PowerCable-2 Standard power cable.
Red. Power: Insert the supplied PowerCable-2 Standard power cable. This provides the
device with a second, redundant power supply.
Initiation
After the appliance has been properly installed, it is ready for operation. Switch on
the Main Power and optionally the Red. Power power pack.
When choosing a location for the device, please ensure to comply with the
ambient temperature limit (see Technical data on page 10 ff.) close to the device.
The ambient temperature limit must not be influenced by other devices.
When installing the devices, make sure to only place a maximum of three devices
directly on top of each other. This way, a good circulation of air is provided and
mutual thermal interference can be avoided. After having installed three devices,
provide for a distance (at least 2 cm).
Do not cover the ventilation openings. For reasons of electric safety, mount the
device variants with ventilation openings only horizontally.
NOTE: Connect the other end of the cable to the network interfaces of any compu-
ter for the initial configuration of the network interface(s).
After the initial configuration (see page 4), the cable is connected to the local network.
NOTE: The interfaces USB 2.0, RS485 and RS232 are provided for future expansions.

Adjusting a common database for
all devices
In order to being able to use the web application of the DevCon-Center appliance to
administer, configure and monitor all devices of the KVM system, the databse set-
tings of the different devices need to be configured.
How to define a device’s database settings:
1. Open the Config Panel web application of the respective device and log in with
your user account.
2. Click the tool symbol in the toolbar.
3. Click the tabs Configuration > Device.
4. Use the Type field to select the Slave option.

in the appliance.
7. Click OK to save your settings.
IMPORTANT: The steps described in the following are to be carried out in the web
applications of the different devices and not in the appliance!
IMPORTANT: Carry out these steps in the web application of all devices that are
to be accessing the common database.

Using the Reset button

Temporarily deactivating the netfilter rules
In the default status of the DevCon-Center appliance, all network computers have
access to the extender’s IP address (open system access).
The web application enables you to create netfilter rules to control the access to the
appliance. As soon as a netfilter rule has been created, the open access to the system is
deactivated and all incoming data packets are compared to the netfilter rules.
If the currently adjusted netfilter rules prevent the access to the Config Panel web
application, they can be can temporarily deactivated in order to be edited.
How to temporarily deactivate the netfilter rules:
1. Press and hold the Reset button on the front panel of the appliance for 5 seconds.
2. Use the Config Panel web application to edit the netfilter rules that are stored in
the appliance and, afterwards, save these rules.
IMPORTANT: Now, the open system access is activated.
IMPORTANT: The former settings are reactivated if no new netfilter rules are
created within 15 minutes.
