6.15.1 Enabling or disabling inputs
Under “External Signal Enable”, select the
switching signals at the connections INPUT
PORT (13) that are to be enabled for switch-
ing over the configuration . A tick in the box
indicates that the corresponding input will be
included in the switchover procedure .
6.15.2 Selecting the logic type
(high / low)
Under “Active Mode”, define if the switch-
over is to be triggered by high level [“External
Input line active High” (+5 V)] or low level
[“External Input line active Low” (0 V)] .
6.15.3 Selecting priorities
Under “Priority”, select the priority to be used
for the switching inputs during switchover .
Click the button “?” to call up a table (fig . 39)
providing information on the actual meaning
of the number entered in the field “Configure
Priority” . For each number, the table lists, in
descending order, the priorities that are as-
signed to the individual inputs .
Example:
All inputs have been enabled for switchover . The
logic type is “active High” and the value in the field
“Configure Priority” has been set to 3, i . e ., according
to the table, the order of the inputs is S1, S4, S3,
S2 . This means:
If switching input 1 is on high level (+5 V are present
between terminal “S1” and ), the 1
st
extra con-
figuration will be retrieved (consequently, the other
inputs will be of no relevance) .
If switching input 1 is on low level (0 V are present
between terminal “S1” and ) and if switching
input 4 is on high level, the 4
th
extra configuration
will be retrieved .
If the switching inputs 1 and 4 are on low level and
if switching input 3 is on high level, the 3
rd
extra
configuration will be retrieved .
If switching inputs 1, 3 and 4 are on low level and
if switching input 2 is on high level, the 2
nd
extra
configuration will be retrieved .

6.16 Selecting the interface mode
Similar to the procedure in the system menu,
it is possible to define if one of the interfaces
USB or RS-485 is to be set manually or to be
recognized automatically by the unit .
1) In the configuration window, under
“USB/ RS 485”, click the button “Setup” .
The dialog window “USB/ RS 485 Setup”
is displayed .
2) From the list field, define if the switchover
is to be performed automatically (“USB/
RS 485 Automatic”) or if the USB or RS-
485 interface most recently set by means
of the system menu (
☞
chapter 5 .3 .3) is
to be used (“USB/ RS 485 Manual”) .
3) Click “OK” to confirm your selection or
click “Cancel” to cancel it .
6.17 Locking the unit
To protect the unit against unauthorized op-
eration, click the button “Lock Front-panel”
on the upper right of the display so that it
appears to be “pressed” . Once the connec-
tion to the computer has been disconnected
(configuration window closed [
☞
chap-
ter 6 .18] and “Disconnect” clicked), it will
not be possible to operate the DRM-882LAN
via its buttons
To unlock, re-establish the connection to
the computer (“Connect”), call up the con-
figuration window (“Edit”) and press (“disen-
gage”) the button “Lock Front-panel” .
6.18 Exiting a configuration window
To exit a configuration window, click the but-
ton
located in the upper right corner . Then
confirm the confirmation message .
