The Port pull-down will provide a list of COM ports available on your PC. The
list will not include the port that is currently assigned to communicating with
the cassette printer, because that port is not available. The Producer CL
program has no way of knowing if other programs on your PC will need ac-
cess to the other ports, so it shows all ports that are installed, rather than
ports that are available.
The Baud Rate, Data Bits, Stop Bits and Parity drop-down lists allow you to
match the ports settings to that of your host system. It is critical that both
devices have the same port settings to avoid communications errors.
4.3 Network Configuration
If you decide to use the network connection type, you are responsible for
ensuring that you have a network interface card installed in your PC, that
the device drivers for this card are loaded and properly configured, and that
the TCP/IP protocol stack is bound to the card.
Once the network interface card is properly installed and working, you must
tell the Producer CL program what TCP port number it is to use to listen for
connection request from your host system. All port numbers less than 1025
are reserved, so pick a number between 1025 and 65535. The program will
default to 4000 and this is a good place to start.
Before you can make a connection to the Producer CL program, you must
know the IP address of the computer. An IP address can be static (that is, it
is assigned to the computer by a network administrator and never changes)
or it can be dynamic (it gets its IP address each time it boots up by asking a
special server for one). For the network communication to work properly, it
is usually necessary to use a static IP address on your computer. That way,
your host system will know what the IP address is, and that it will never
change. You must see your network administrator before statically configur-
ing an IP address on your computer.
Failure to follow this rule can result in duplicate address on the
network – and that is a BAD THING.
