LINK Systems LinkNet II - Manual (Page 28)

4.5 Communications Port Configuration
LinkNet uses a standard RS-232
serial port (commonly called a “comm
port”) to communicate with the
machines on the factory floor via an
external RS-232 to RS-485 converter.
No boards have to be installed or
configured on the host computer. There
are typically two comm ports installed in
most computers, “COM1" and “COM2",
although others may be present as well.
An unused comm port must be available
for LinkNet to use.
Select “Configure” and then “Comm
Port” from the menu in LinkNet and a dialog box similar to Figure 4.9 should appear. Note that only
comm ports that are not currently in use (by anything other than LinkNet itself) show up in the “Comm
Port” list. Pick the comm port that will be used by LinkNet from the list and click on the “OK” button.

NOTE: The various timeouts and delays in this menu are present for troubleshooting
only. Do not change these values unless instructed to do so by a Link representative.
Doing so could render communications unstable or unusable!
