Q:
How do I change the com port settings?
A: If you need to change the port settings, the
port must be closed, then click on the "Communications" menu and
select 'Com Port Settings...' to open the settings window. You
can also press F9 to open the com port settings window.
Q: How do
I open or close a com port connection?
A: Click on the "Communications" menu at the
top of the main window, and select 'Open Port' to open the com port
selected in the Com Port Settings window using the specified serial
settings. To close the port click on 'Close Port' also located
under the "Communications" menu. You can also use the speed
keys F11 and F12 to Open and Close the com port.
Q: How do
I send an RS-232 command string to the com port?
A: You need to build the command string using
any combination of ASCII, Hex, or Decimal bytes. To add plain
ASCII printable characters, type the letters into the 'Add ASCII
Values' text box, and click the add button. The character
sequence you typed into the text box will be appended to the 'Send
String' and shown in the text window just below. To add Hex
byte values, click the "Add Hex bytes" button to display a byte
chart for all hex values from 00h-FFh. Clicking these values
will add hex bytes to the 'Send String' being built. For
decimal bytes, enter a decimal value (0-255d) and click the "Add"
button. Once your command string is built from any mixture of
byte types, click the "Send String" button to send the command to
the com Port.
Q: Where
do I view the data received from the com port?
A: The main window's "Receive Data" text window
shows you the ASCII characters that are received from the com port.
This window is most useful for viewing data in the "readable" or
"printable" ASCII range.
Q: How do
I view the received serial data in HEX bytes?
A: The main Received Data window displays the
bytes in printable ASCII characters. To simultaneously view
the same data in Hex, simply click the "Show Hex Values" check box
next to the main receive window. You will see a new window
dock to the bottom of the main window, and will show Hex value bytes
(separated by commas between values) of the received data.
Q: What is
"Bridge Mode"?
A: Bridge Mode is when the program uses 2 com
ports (set to the same serial settings with the exception of the
port number) to pass data through the program to each of the ports.
This enables the user to take an existing point-to-point serial
connection between 2 other devices and analyze and interject data
into the connection. Think of as an electronic wire-tap, the
laptop intercepts both sides of the communication, and then passes
each side to the other, so the 2 communicating devices to not know
there is a 3rd device in-line "listening" to the data.
Q: How do
I activate and use "Bridge Mode"?
A: Bridge Mode is activated under the "Com Port
Settings" window. On the right hand side, there is a section
call "Replicate Port Pass thru". By default, this setting is
to "Do not Replicate", which means that Bridging is off. To
activate it, just select which com Port you want to use on your PC
as the second port. The same serial speed and settings will be
used for the 2nd com port as the for the main com port. You
will see an extra window docked to the side of the Main window.
This window, shows incoming data from the 2nd com port, and the main
receive text window displays the data received from the main com
port, to allow to you simultaneously view both sides of the
communication data. |
