3. In Windows 95, go to the “Start” menu, and
access “Settings”, then “Control Panels”, and
finally “Add/Remove Programs”.
4. Click on “Install” and then follow the on-screen
instructions.
Once the Configuration Program is installed on the
PC, the TRZ can be connected to equipment to
simulate input and monitor output. With the PC
program, the user can then view and/or change its
operating parameters.
If not using a PC...
Use the HART Communicator to specify the operating
parameters of the TRZ.
If using a PC...
It will be necessary to install Moore Industries’ TRZ
Intelligent PC Configuration software first. Once the
program is loaded and running, nearly all of the
operating parameters for the connected transmitter
are shown on a single screen (see Figure 4). This
makes it easy to determine which aspects of
transmitter operation need to be changed to suit the
application requirements.
Installing the TRZ Configuration Software
Refer to Table 2 for the specifications of the PC
needed.
1. Insert the diskette labeled “TRZ Installation”
into the floppy drive of the PC.
2. Quit any applications that may be running in
the background on the PC, including any virus
detection software or other programs running in
Terminate and Stay Resident (TSR) mode.
