GENERAL
In this group of settings, you have to specify the device the DB2003 is to monitor/control and how
to connect to it. Setting an Alias allows the user to recognize the different monitored devices. This is
where you enable/disable the port.
Select Model & Connect
The set interface must match the one which is physically connected. The address and speed of the
connection must correspond to the ones set in the monitored device. With the I
2
C interface, speed is
not taken into consideration.
With different interfaces, the address can be the same for several ports, but when the connection
is over I
2
C, different addresses must be set to differentiate between devices. If required, set another
address into the monitored device.
The models in the PTX_LCD, PTX_DDS, PTX_LCDDSP, TEX_LCD and Blues series have
different nominal forward power. If you select another model from the same series, which is different
from the one actually connected, the DB2003 will not be able to tell the difference. The power in
W when setting alarm and dayparts thresholds will be calculated against the nominal power of the
set model. For alarms, power is compared in W, while for Target Power command values are in
percent. That will lead to a difference between the transmitter’s power and the power expected by
the DB2003.
The models from the Plug-in KPS-CA and Barracuda series differ by the number of RF Units.
When a model is set, which is different from the one actually connected, the DB2003 will not display
the data from all RF units or will try to request and display data from non-existent RF units.
It is highly recommended that you set a model precisely as the one connected.
Dangerous Parameters
The change in some parameters is dangerous, e.g. the change in the transmitter’s frequency. The
DB2003 has a designated mechanism to limit such actions, therefore the default Edit Dangerous
Parameters value is Disable. In this case, the dangerous parameters are not available for telecontrol.
When the selected value is Enable, the dangerous parameters are displayed and can be edited. They
are marked by a warning sign.
When you have selected the value “ For a limited time ”, you see a ticker counting seconds down
- this is the time in which the new value must be entered and saved. This mechanism presupposes
awareness of whether the operator’s actions are necessary.
