7.3 Connecting the ports
The three non-SNMP Links defined in PCNC - Control, Remote and
Auxiliary - are configured in three separate sections of PCNC.INI. Each
Link you use will have a corresponding COM port on the PC. A Link can
be used to send commands to devices from a Terminal, or gather alarms
from the network. Different Links provide different facilities, as shown in
the following table:

7.3.1 COM Ports

In order to receive alarms from non-SNMP devices, you must have
either a Control Link, a Remote Link or both.
optional. For each Link you plan to use, you will need a serial port on
your computer. Under Microsoft Windows , serial ports are named
COM1, COM2, COM3 and COM4. To receive alarms over TCP/IP, you
need a Network Interface Card, TCP/IP software and the optional SNMP
Link (see Chapter 5).
Most PCs have either one or two serial ports, but you will need three if
you plan to use all of PCNC's Links. If necessary, you can increase the
number of ports by adding an expansion card.
You also need to identify which port is COM1, which one is COM2 etc,
so that you can make the correct connections to your network.
When this is done, you can set up the INI file, as described in the rest of
this chapter. Details of each entry can also be found in the on-line help.
