• Serial Port 1 Unit Addresses
• Serial Port 2 Unit Addresses
These settings enable the serial communications path to be treated as a sin-
gle FINS network. Further, the network address allocated to the serial port
can be specified in the destination network address part of the FINS mes-
sage. This enables messages to passed on to serial ports in a system com-
prised of multiple networks connected to a single PC (including the serial
communications path).
