4.1.3.2 Docking station with motherboard
Optionally, the docking station is equipped with a motherboard.
The motherboard is available in 3 different versions. The differences refer to the design of the
power supply. Otherwise, the motherboards are identical.
• BEX122 motherboard - Power supply via PoE
• BEX121 motherboard - Power supply by 24 V DC
• BEX120 motherboard - Power supply by mains voltage
In general, the motherboard has the following hardware equipment:
RS-232C interface
The RS-232C interface can be used for connecting an external reader, for example a CCD bar-
code scanner.
It is connected to the RJ45 socket of the motherboard.
Additional interface
The motherboard has a slot for an optional interface module. The BEX301 - RS-232C interface
or BEX302 - RS-485 interface can be used.
The interface can be used for customized applications. The additional interface is without use
in the standard equipment.
The interface signals are connected via a 6-pin terminal on the motherboard.
Outputs
The motherboard has 2 relay outputs with changeover contacts. The relays can be used, for
example, for activating door openers or signal generators.
Inputs
The motherboard has 4 digital inputs. The inputs can be used for a door opener key, access
control or a customized application.
Sabotage contact
Devices whose docking station is equipped with a motherboard are provided with a sabotage
contact.
The sabotage contact is activated when the terminal housing is disconnected from the dock-
ing station plus motherboard.
This causes the device to generate an appropriate alarm record. Prerequisite: Device supplied
via PoE or via a UPS510. Not possible for devices supplied by the motherboard and not
equipped with a UPS, since after removal of the terminal housing from the docking station
the power supply is also disconnected.
Whether hardware options are supported, depends in part on the terminal software used and
the acquired software options!
