In Telnet mode, PORT addresses need to match between both
transceivers or Telnet devices and the TUNNEL_IP settings
must be the IP address of the opposite end transceiver or
Telnet device. For this example, both transceivers will try to
establish a connection by toggling between initiating a
connection and passively waiting for the opposite transceiver
to initiate a connection. This works well when tunneling
between transceivers and port servers of different
manufacture. It does not matter if the remote port server is
set to master or slave because the SEL-2890 will toggle back
and forth until a connection is made. Once a connection is
made, the SEL-2890 will stay in that mode until the
connection is terminated.
BTCP Mode
BTCP mode provides the ability to broadcast serial data
without establishing a point-to-point connection. Refer to
Figure 1.3 for a typical broadcast connection method. Note
that all devices must be on the same side of the router.
Routers will not broadcast messages outside of the local
network. The following list contains the necessary settings to
set up broadcast polling.
