DESCRIPTION: This screen allows the technician to
view the status of all serial communications ports. or
the status of all Modbus TCP communications. Refer
to the section entitled Modbus TCP Log in the Mod-
bus Protocol chapter.
The following user selectable buttons are provided:
• [Show Comm1]

• [Show Comm3]
• [Show Comm4]
This screen allows the technician to view all of the serial
communications information that the Quantum™ LX is re-
ceiving and transmitting, one port at a time. Simply select
the button at the upper right side of the screen that cor-
responds to the port that you wish to view. The selected
port name (in this case Comm4) will appear in the upper
left side of the screen.
Each time a new command is sent or received, the screen
will need to be refreshed by selecting the [Show CommX]
button (where X is replaced with the comm port number).
The top line of data is the most recent activity. At the left
of each line, you should see whether the data is IN or OUT

format). This information can be used to compare against
the data being sent and received at the other end of the
communications link, to verify proper operation. Refer to
the section on Hyperterminal for some examples of how
this screen may be used.
