Alarm relay (X4)
The devices are equipped with a potential free alarm
output (relay with isolated switchover contact). This
output corresponds to a device alarm and is activated
when the device looses the power supply or the alarm
LED is constantly on. The reason for the signaling of an
alarm can be referenced in the system alarm table.

Configuration using a serial configuration cable
The serial interface provides access to the command
line. Using a serial configuration cable (500CAB06
1KGT038912R0001), the device can be connected to a
serial port of a PC/notebook.
The default configuration for the serial connection is:
57600 Baud 8N1 (8 data bits, no parity, 1 stop bit), no
hardware flow control.
The command line interface
The command line of the 500FSD20 is similar to the
(DOS) command line known from the PC. All device
properties can be set and shown here.
•
Commands are typed into the console, pressing
< { E n t e r } >
will start execution.
•
Commands can be abbreviated as soon as they
are unambiguous, i.e.
< s h s y >
is equivalent
to
< s h o w s y s t e m >
,
< s e i f w 4 >
is
equivalent to
< s e t i n t e r f a c e f s k 0 w i r e
4 >
.
•
A command overview can be listed on every level
by typing
< ? >
. Example:
< s h a l ? >
translates
to
< s h o w a l a r m ? >
and results in
a c t i v e
e n a b l e d
being shown as command keywords
to follow, i.e. one possible command is
< s h o w
a l a r m a c t i v e >
.
•
There are two authentication levels on the
command line: Login authentication and Enable
authentication. Login authentication can be
described as a read only mode and is accessible
directly after establishing a serial connection
with the PC. Enable authentication is required
once you need to change system settings or
show the complete system parameter set.
Enable authentication is reached by entering
the
< e n a b l e >
command. Both authentication
levels can be protected by a password, the
respective commands are
< s e t l o g i n p a s s
{ s t r i n g 2 0 } >
and
< s e t e n a b l e p a s s
{ s t r i n g 2 0 } >
.
