Assembling the device
92
Connecting the Access Manager or Access Manager Terminal (control unit)
and external reader to the power supply
ATTENTION!
The control unit will be unable to recognise the external
reader if the control unit is connected to the power supply
before the external reader.
First of all, connect the external reader to the power supply.
There are three options for supplying power to the devices:
Option 1: Mid-Span Device (e. g. PoE injector)
When using PoE (Power over Ethernet) via a “Mid-Span Device” it is
necessary to connect wires 7 and 8 of the Ethernet cable to terminal 5 of the
DOM device and wires 4 and 5 of the Ethernet cable to terminal 6.
Option 2: End-Span Device (e. g. PoE injector)
If a PoE "End-Span Device" is used, power is supplied on the data lines at
terminals 1 to 4 (wires 1, 2, 3, 6). In this case, terminals 5 and 6 are not
required.
Option 3: An external power source supplies the device.
If you operate the device with an external power source (12 V – 24 V DC),
connect the positive pole to terminal 7 and the negative pole to terminal 8.
An external reader can be energised via the DC out function. Terminals 9 and
10 of the control unit are connected to terminals 7 and 8 of the external reader
for this purpose.
