• auto configuration of the control modules
• minimal wiring due to the bus technology
• all assignments can easily be changed with the Commander at any time
• illuminated track symbols and illuminated fields for individual marking
• individual and group buttons for turnouts and signals
• control button for routes
• several track diagram panels up to 100 m apart are possible
• symbol plates of 22 x 22 mm with 1 plug only
• symbols for turnouts and signals with multicolour status display
• very compact due to clever design of the symbol plates

All track diagram symbols of the diagram panels are ready-made and have a connection wire with a standardized four-pole-plug. The symbols can be inserted from the top to a base carrier - the GBS module 5380. It carries 4 x 8 = 32 symbol plates. The plug is connected to one of the 16 ports of a connection board (5308) respect distribution board (5307). Both can be placed under the GBS-carrier module.

The intelligence of the complete diagram panel is concentrated inside the Commander. Therefore the symbol plates can be kept simple and cheap. The Commander is necessary as control device for the track diagram panel. One Commander can manage several track diagram panels. They are connected to the Commander by a single LSB (SpeedBus) cable. In order to connect the track diagram panel to the Commander, at least one distribution board (5307) is needed for each track diagram panel. This board translates the information of the diagram panel to the LSB information. The distribution board has already one integrated connection board with 16 plugs for symbol plates. Further connection boards can be connected to the distribution board.
