✯ Failover: Where the primary TCP-session has exclusive access to
the serial port until disconnected. Secondary TCP-session data will
be handled when the primary session has disconnected, i.e., act as
backup. When the primary TCP-session comes up again, it will get
back the exclusive access to the serial port once data is received on
the primary TCP-session.
When the secondary TCP-session is in backup state, incoming data
on the secondary-TCP session is ignored.
✯ Raw: In this case, data from both TCP-sessions are directly for-
warded onto the serial port without any handling. Data received
from the serial port is returned to both TCP-sessions. Note: This
means that the applications connecting to the TCP ports have to
take full responsibility for the concurrent access to the serial port.
Default: Slotted, timeout 600 ms
Configuring a secondary (TCP server) listen port in WeOS, corresponds
to the Dual TCP feature found in Westermo EDW-100 units. The table
below translates between WeOS and EDW-100 settings.

– Multicast group: Multicast group to receive data from. This is only ap-
plicable in Peer (UDP) mode. IP multicast addresses are in the following
range: 224.0.0.0-239.255.255.255.
When configured, the unit will accept packets to the stated multicast
address, when received on the interface and (UDP) port declared in the
Listen setting. Note: the unit will still accept unicast and broadcast
packets as described in the Listen item above.
Default: Disabled
– Destination/peer: IP address and (UDP/TCP) port numbers to relay data
to/from. This setting is only applicable in Client and Peer modes. In
Client mode, the destination address should be the IP address of the
