Setting the S
TELLAR
addresses in ROSA/C
OPERNICUS
Addresses AS
TELLAR
has two addresses:
• One address for the unit type, for the S
TELLAR
51 (hexadecimal), so ROSA recog-
nizes the type of unit connected, and
• one unique remote address, so ROSA can communicate with each single unit.
To give the S
TELLAR
a
unique remote address
To give the S
TELLAR
a unique remote address do as follows:
1. Connect the S
TELLAR
via its remote RS-485 port to the serial port of the
C
OPERNICUS
server and power it up.
2. Press the Receiving Attention button on the S
TELLAR
front for at least 3 sec-
onds and release the button when it flashes with an interval of approxi-
mately one flash per second.
The communication speed and remote address will be set automatically between
the S
TELLAR
and the server. After successful configuration the Receiving Atten-
tion LED will turn off unless the receiving attention situation is active.
Note! If multiple S
TELLAR
decoders need to be configured, they can all be
connected at once to the C
OPERNICUS
.However,beawarethatthe
remote installation procedure can only be performed for one S
TEL
-
LAR
at a time, meaning that you must not press more than one
Receiving Attention button at the same time.
To set the scan range To let ROSA look for addresses of new S
TELLAR
units, do the following:
1. Right-click on the serial port to which the S
TELLAR
is connected and select
Properties.
2. Select the New Unit Scan Ranges tab.
3. Select the S
TELLAR
andclickAddScanRange.
4. Set the scan range from 10 to 10 if you are connected locally.
5. Set the scan range from 70 to 7E if you are connected remotely.
The possible scan range is from 1 to 7E. When limiting the range to from 70 to
7E, you limit the number of units to poll for and consequently speed up the poll-
ing sequence.
6. Click O.K.
Note! The C
OPERNICUS
server automatically scans the network for new devices. However,
it is always a good idea to limit the scan range to only include the active devices, as it
speeds up the user interface.
