Getting Started
Session 9: Loading Data from a Host
In this Session, you will learn how to download data from a host to the
programmer through one of the serial ports on the programmer. The
procedures in this Session apply to many types of hosts, including VAXes,
UNIX-based workstations, and DOS-based PCs.
Note: If you are using a DOS-based PC, we recommend that you
use HiTerm as your terminal emulation software. Downloading a file
with HiTerm is covered in the previous Session.
This Session assumes that you have a host connected to one of the serial ports
on the programmer and a terminal connected to the other serial port on the
programmer. This type of configuration is called Transparent mode.
Terminal/
Workstation
See Chapter 2, Setting Up, for information on connecting a host and terminal
to the programmer.
About Transparent Mode
Preparing the File
T R
Transparent mode allows the programmer to be connected inline between your
terminal and host computer, eliminating the need for a switch box or a second
link to the host and enabling you to download directly from the host to the
programmer. The host could be a networked file server, such as a VAX or a
Sun. When set up properly, the terminal connected to the programmer can
control both the programmer and the remote host.
In Transparent mode, the programmer passes all characters through its
Terminal and Remote ports as if it weren't there. The two serial ports on the
programmer can even operate at different baud rates. While operating the
programmer from the terminal, press ESC CTRL+T to toggle the programmer
between terminal mode and transparent mode. The programmer remains in
transparent mode until it receives another ESC CTRL+T = command, which
switches it back to terminal mode.
Using your development tools, create a small sample data file. For the rest of
this Session, the sample data file will be referred to as sample.dat. If you
give your sample data file a different name, substitute that name where you
see sample.dat.
Also, the rest of this Session assumes that your sample data file is stored in
the Intel Intellec 8/MDS data translation format. If your data file is in a
different translation format, use the Format Select command to select that
format. See Session 7 for information on selecting a data translation format.
