5. As the transceiver initializes itself on power-up,
watch the LED lights on the side of the transceiver.
You should see the lights flicker briefly with a burst
of activity. You may see occasional flickering of the
lights after this initial burst.
6. After the brief burst of LED activity, open the trans-
ceiver setup screen in the PC software and check
the “Last Power-up Settings”. If they show the Net-
work ID = H and Transceiver ID = H settings as
described above, the serial connection between the
PC and the transceiver is functioning properly.
7. Close the transceiver setup screen.
8. Power down the transceiver and restore the dip
switch settings to their Network ID = A, Transceiver
ID = A settings.
9. Power up the transceiver.
10. After the initialization activity reflected by the lights
on the transceiver, open the transceiver setup
screen and confirm that the “Last Power-up Set-
tings” read Network ID = A and Transceiver ID = A.
If the “Last Power-up Settings” do not update, one or
more things may be happening.
First, the serial port selected on the transceiver setup
screen may not be the one the serial cable is plugged
into. Many newer computers have only one serial port
on the back of the computer; the port may or may not be
COM1. It could easily be another COM number, so if
other COM ports show up in the transceiver setup
screen’s drop down list for Serial Port selection, try
using each of those in turn and repeat the above steps.
Many new computers have no serial ports at all, in which
case a USB to RS232 converter is required to supply at
least one serial port. Graco recommends the purchase
of Edgeport brand USB to RS232 converters, available
from www.bb-elec.com
. Follow the installation instruc-
tions for the converter carefully and make sure you
reboot the computer when complete. Again, don’t
assume the COM port number—the documentation with
the converter should help explain what COM port num-
ber the converter will provide.
When the Matrix PC software starts up, one of the first
things it does is check with Windows to find out what
serial ports (COM ports) exist in the system. These
ports are the ones listed in the Serial Port drop down list
on the transceiver setup screen. If a port you expect is
not listed there, it is because it is not registered as a
valid port with Windows.
Second, the selected COM port may be in use by
another program on the PC. In this case, even if the
Serial Port selection on the transceiver setup screen
matches the port the cable is plugged into, no Matrix
communication will happen because a different software
program “owns” the port. The only way to get it to work
is to either shut down the other program or configure
either the other program or Matrix to use a different
COM port. Software programs that use serial ports
include fax software and PDA software.
Third, the cable between the PC and the transceiver
could be either bad or wired improperly. The latter is
most likely to occur when an RS422 connection is used;
the former could happen with either serial cable choice.
Make sure the cables are firmly connected, so that there
isn’t a chance the plug or wire is falling out on either
end.
Repeat this setup for each Transceiver ensuring that no
two Transceivers use the same Network and Transceiver
IDs. If you have only one transceiver, Graco recom-
mends using the default Network ID and Transceiver ID
settings.
Matrix Client PC Setup
The lower portion of the System Configuration page is
used to register a networked PC client in the Matrix sys-
tem. Without registration here, a client PC will have lim-
ited functionality (such as not being able to submit work
orders to meters or viewing system-wide alerts/errors)
even though many of the screens will still be viewable
from the client.
Note that by default, the PC client table on this page has
one entry; this entry corresponds to the Matrix Server
and always must be present. Graco recommends you
not change this entry’s name/address field from
127.0.0.1, nor the port number from 8082 unless there
are known port conflicts.
Every PC client in the Matrix system is either a “shop cli-
ent” or a “primary client”. Exactly one PC in the system
can be the primary client. Both types can view the
Matrix screens and run reports, but only primary clients
can access the Matrix setup screens and display sys-
tem-wide alerts/error messages. The Matrix Server can
always access the setup screens, regardless of the cli-
ent type it is set to.
