In addition to the above described staus line, the status of the CAN bus is displayed:
Bus online
changes to
Bus offline
if e.g. the CAN bus is unplugged or because
of lacking a terminator. Besides that the
CAN open Node
statuses
stopped
,
pre-
operational
or
operational
are displayed.
The following keys have a specific function:
-
with
N
the node address in a range from 1 to 127 can be chosen.
-
by pressing
B
the listed baudrates can be chosen, the function autobaud is not
implemented.
-
by using key
C
the
PDO_1
operational mode can be selected. Choosing a
value between 1 and 240 the synchronous, cyclical mode can be picked. By
selecting 255 the asynchronous mode is set. The two following modes are only
available in the asynchronous mode:
-
D
is the inhibit time of
PDO_1.
In
PDO_1
the system status and the cal-
culated distances are transmitted. The inhibt time is the shortest time
period between two periods that can be achieved.
-
E
is the time of the cycle of the
PDO_1
transmission. If both values are 0,
PDO_1
will no be transmitted.
-
by pressing
F
the operational mode PDO_2 is selected. Choosing a value
between 1 and 240 the synchronous, cyclical mode can be chosen. By selecting
255 the asynchronous mode is set. The two following modes are only available in
the asynchronous mode:
-
G
is the inhibit time of
PDO_2
. In
PDO_2
the four analog antenna voltages
are transmitted. The inhibt time is the shortest time period between two
periods that can be achieved.
-
H
is the time of the cycle of the
PDO_2
transmission. If both values are 0,
PDO_2
will no be transmitted.
-
I
can change the so called
Heartbeat time
. Together with this time of the
cycle a control message is sent. If the time equals 0 no message is sent.
-
with
A
the autorun is (de)activated.
-
if autorun is deactivated only the
Heartbeat
message (if activated) is sent
after turning on the device. The mode of the device is
preoperational
.
-
if autorun is activated the
Heartbeat
message (if activated) and the
PDOs
are sent immediately after turning on the device. The mode of the device is
operational
.
-
by pressing
L
the order of the bytes within the
PDOs
is changed: by choosing
Lowbyte first
=
1
the low order byte of a 16bit word is transmitted first.
