PCCU32 Connectivity
RS-232 Local Connect
The RS-232 local connection requires a serial port on the host computer
(generally a laptop). A PCCU cable is required to connect the host
computer to the flow meter's round military connector. Connecting the
PCCU cable to the flow meter will cause an annunciator in the LCD to
display an upper case letter "L" for local connect. To connect PCCU32 to
the meter, click the Connect to Totalflow icon on the toolbar. To connect
and move directly to Entry mode, click on Entry instead of the Connect
icon.
If the meter has been given a security code, the user needs to ensure
that they have entered that code in the PCCU32 System Setup screen.
The factory default for a security code is 0000. Cold starting the meter
re-establishes the 0000 security code; however, cold starting the meter
also deletes historical data.
USB Connectivity
Note: USB connectivity requires PCCU32 version 7.17 or higher.
The first time that the user connects their laptop to a G4 meter using the
USB connectivity, the appropriate drivers need to be installed.
A
Connect the G4 meter (XFC/XRC) to the laptop. After a couple
of seconds the "Found New Hardware Wizard" will appear. It
will ask if, "Windows should connect to Windows Update and
search for software?"
Select "No, not this time" and click "Next" to continue.
B
The next dialogue box will ask, "What do you want the wizard
to do?"
Select "Install the software automatically (Recommended)" and
click "Next" to continue.
C
At this point you will get a Microsoft® message warning that
the Totalflow USB driver has "not passed Windows Logo
testing". If you want to use your laptop's USB port you will
need to click on "Continue Anyway" and proceed with the
installation.
D
The "Found New Hardware Wizard" has finished. Click
"Finish". The Totalflow USB driver is now installed.
NOTES:
The above procedure creates a virtual com port on the laptop.
The com port disappears when the meter is disconnected.
The com port can be seen to appear and disappear in the
Device Manager whenever the USB cable is connected or
disconnected from the laptop.
