Make sure you click “Applyevery time, after making any changes. If you move to a different window
without clicking “Apply”, the changes are not saved.
Step 2. Target PC configuration
xPC Explorer identifies each PC104 system as a target PC. By default the explorer will start with one
target named TargetPC1. Each target PC can be programmed to run in either “Standalone” mode or in
“DOS Loader” mode. We will look at each mode, their uses and how to configure them.
Step 2.1. Standalone Mode
In standalone mode, any program
you build into the PC104 board will
run as long as the system has power.
After a power reset, the same
program will start running as soon
as the system boots up. No user
intervention is required to start the
program at all. To enable standalone
mode select Enable Standalone
Mode” and click apply as shown in
the image. You will learn later to
download and run a program on the
PC104 board using Standalone
mode.
Step 2.2 Dos Loader Mode
In this mode of target programming, the target computer has to be connected to a host PC at all times. If
there is a power reset, then the host PC has to resend the program to the target or else the target will
simply boot and wait.
There are two types of Loader modes. One is Ethernet (TCP/IP) and the other is Serial (RS-232). These
two modes determine the connectivity between the host PC and the target computer. To use Dos loader
mode, Standalone mode should be disabled. Once the communication setting is selected as either RS-232
or TCP/IP a dos loader file must be created and copied on to the flash disk. We will now see how to do
this, first for serial and then for Ethernet.
