2.5.6 Mixed Modes
Note that the IP-to-Serial mode does not involve the Access Point. Thus
the iNETs in a single network can run in both modes at the same time.
In other words, some Remotes can be configured for IP-to-Serial mode
while others are configured, along with the Access Point, for the
Serial-to-Serial mode. In this configuration, the Host PC can use both
data paths to reach the RTUs. This may be helpful when a mixed collec-
tion of RTUs is present where some RTUs can operate in a broadcast
form while others cannot. (See Figure 2-19 and Table 2-4)

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.
2. This address is an example only. Any Class D IP address will work.
