USB Type B Connector
Refer to Diagram: The USB connector is a common type B connector found on a
variety of electronic devices. This port will be used to transfer stored grid/log files,
captured screen shots, etc. This connector will also be used to upgrade the DFX-8
with the latest version of firmware (gauge software). The cable supplied with the
DFX-8 is USB type A to USB type B.
RS-232 Serial Connection (LEMO 1 – 5 pin)
Refer to Diagram: The RS-232 connector is a 5 pin female Lemo 1 connector. It is
designed to connect directly from the DFX-8+ to a standard AT serial port on a PC,
and works in conjunction with the integrated “remote commander” feature built for
system integration in the DFX-8+ “only”. A standard terminal software program must
be installed and configured, like HyperTerminal from Windows, in order to use this
feature. Basic commands can be sent from a PC keyboard to the DFX-8+ through
the serial portion of the connector to remote control the gauge. An accessory 9 pin
female serial to Lemo 1 - 5 pin male cable will be required to use this feature, and is
not included in the standard kit.
Terminal settings for serial communication and a list of the current set of commands
available in remote commander are shown in the diagrams below. They can be
displayed at any time by typing ‘help’ in the PC terminal window, followed by pressing
the enter key. You’ll notice that some of the commands have an ‘n’ next to them.
These require either a number to change the value for the given parameter, or a ‘?’ to
report back to the user the current value of the parameter.
