If only one interface has been selected, only the corresponding data rate filed is enabled. The other one is
disabled.
Transmitter and Receiver Address for digital interfaces
When several SWT 3000 links are connected in the same digital network via multiplexers a unique addressing
of transmitting and receiving device avoids unwanted operation of SWT 3000 devices due to incorrect routing,
switching or cabling in the digital network. Associated local and remote SWT 3000 devices are identified
within the network by the address bits transmitted with the DLE data stream.
Configure a unique transmitter address and the receiver address of the associated SWT 3000 device for digital
or fiber-optic connections via the LID – interfaces of the DLE. The following figure shows the principle of
addressing for associated devices.
The range for TX- and RX- addresses is 1 … 255. The address range is reduced to 127, if line clock sync or
command loop test is enabled. The device address settings apply to both digital connection interfaces simulta-
neously.

NOTE
Wrong or invalid address settings may cause malfunction of the teleprotection signaling in associated
and/or non-associated devices of the digital network.
Reflection
Reflection is configurable for all protection operating modes except of Mode 3, Mode 4, Mode 5D and Mode 6.
With activated Reflection the SWT 3000 transmits the received commands back to the equipment at the
opposite side, as long no excitation input is activated. Therefore Reflection may be configured only in one
SWT 3000 device of a connection.
Reflection of received commands is only executed, if the excitation signal is not active and is terminated
immediately with activation of the excitation input for control of the S6 signaling. The excitation of the S6
signal is provided by activation of binary input BI4 in the operating modes Mode 1 and Mode 2. In Mode 3a,
Mode 3b and Mode 5A the S6 signaling is activated automatically with activation of any binary input.

Description
Reflection
No (default)
The received commands activate the local outputs of SWT 3000.
Yes
The received commands activate the local outputs of SWT 3000.
As long the excitation input is not actived during the command
reception, SWT 3000 transmits the received commands back to
the equipment at the opposite side.
