2.6.9 Combined Serial and IP Application Example
Note that in this example, the TCP mode does not involve the Access
Point. Thus, the transceiver in a single network can run in
both modes at
the same time. In other words, some Remotes can be configured for TCP
mode while others can be configured (along with the Access Point) for
UDP mode.
In this configuration, the Host PC can use both data paths to reach the
RTUs. This may be helpful when a mixed collection of RTUs is present
where some RTUs can operate in a broadcast form while others cannot
(see Figure 2-40 on Page 76 and Table 2-4 on Page 76).
Operation and Data Flow
• Communicate with RTU A by Telneting to Remote 1, port 30011.
• Communicate with RTU B by Telneting to Remote 2, port 30011.
• Communicate with RTUs C and D by sending and receiving data
from the Access Point’s
COM
port.
• All communication paths can be used simultaneously.

1. Either COM port can be used, but they must be the same ones at both ends
of the link. Both COM ports can be used simultaneously for two independent
data channels.
