Software
The following is a brief overview of how to get started with the DI-1000 Configuration Software. A detailed expla-
nation of the configuration software is provided in the help files within the configuration program.
More than likely, you will not need to use the configuration software; it is only necessary when you wish to change
the Baud Rate you will communicate at (the default Baud Rate is 9600), or - if you have multiple instruments that
were shipped separately - to change the modules' addresses. If you want to change the Baud Rate or if you have mul-
tiple devices daisy-chained together, you must run the configuration software.
When you install software from The W

in your Start > Programs menu. To configure your device(s):
1.
Connect the device to your PC and then run the configuration software. When the initial screen comes up, select
Configure > Port or click on the Port icon. Then select the port you are connected to.
Note: When using a USB
Port it is important to know that Windows automatically assigns a Port that is not necessarily the next Port avail-
able on your PC. To find out what Port has been assigned to your USB module check your Windows Device
Manager or try assigning a Port until you get the correct one.
2.
To set your Baud Rate and your Address, select Configure > Setup or click on the Setup icon. Here you can set
your Baud Rate and your Address. This must be done
separately
for each device. Note that they all must have
the same Baud Rate and the addresses must be synchronized (see below).
Note: Each device must be connected
and configured separately - before daisy chaining. Changes take effect when power is re-applied to the instru-
ment (i.e., you must disconnect and reconnect power for changes to take effect).
Setting up Addresses for Your Devices
The default address for all devices is 1. This is the address for the master device. You can leave it at this address if
you are only running one device. If you take a networked group of instruments and wish to run them all separately,
you must change their addresses to 1 (the Master address). If you then wish to re-create the network (or create a new
network), you will need to change the addresses for all devices except the master. This is done in the Setup window
of the Configuration Software. Each device beyond the master should be numbered sequentially (2, 3, 4, etc.). Each
device must be connected individually to set up its address. In the Setup window, you will have to enter the desired
address for the device you are configuring, the address of the master, and the address of the previous device on the
chain. See the diagram below for an example.
The use of master and previous addresses for each DI-1000 module allows the modules to synchronize their acquired
readings. Essentially, the master paces the data acquisition scan rate, and each slave follows suit. A typical sequence
is as follows:
Note:
All modules’ addresses are pre-configured direct from the factory. Setting addresses is only
necessary when changing the configuration of your network (i.e., adding or (re)moving instruments).
