LabeLase ® Producer - Installation
File Transfer - When the printer's PC is connected to your host computer via
a network interface, but it is impractical for you to interface via the TCP/IP
protocols, the file transfer connection type may be selected. When enabled,
there is no actual protocol used to transfer the data. The host computer sim-
ply writes a file containing the data (one or more records separated by CR/
LF) to a specific location on the printer's PC. The Producer CL program will
check for this file once every second and when it finds it, it will read its con-
tents and then delete it. The host must recreate the file the next time it
wishes to send data. Each record in the file is in the Standard Message For-
mat and applies to one or more cassettes as needed.
When connecting to the host via a network, the TCP/IP protocols are used.
The Producer CL program will act as a server and will listen at a specific
TCP port number for connection requests from the host. You must specify
the port number at which the Producer CL is to listen. Note that the type of
network (Ethernet, Token Ring, etc.) is not important to the software since
TCP/IP is being used as the low level protocol.
4.2 Settings of the serial RS232-C interface
If you decide to use RS232-C as your connection type, you must provide a
cable to connect your host system to the COM port on the PC. You must also
configure the port's settings to match those of the port on your host system.
This configuration is carried out using the Producer CL program's Host Com-
munications Setup form.
Using this form, you must choose a port on your PC that is not used for any
other purpose. The Producer CL program will open this port and keep it
open for as long as it is running, so no other programs can have access to
the port. Also, since the Producer CL program uses a COM port to communi-
cate to the cassette printer itself, you must have at least two free COM ports
on your PC to use the RS232-C host communication type.
