RS-232C Port
An important feature of the FGV-X family of gauges is
the RS232C communications port. Data and commands
can be linked to a PC or any other device responding to
RS232C signals for storage or further analysis. Table 1
(below) describes the function of each pin of the
connector (HR12-10RC-10SDL) shown in Fig. 3.

Commands/Responses
The FGV-X series of force gauges has the ability to
recognize and respond to various commands from
outside peripherals. If for instance the gauge receives a
legitimate command from a PC, it will respond by sending
back the same code indicating to the PC that the
command was recognized. If for example the command
is a request for average data output, it will send the
data and the code NA etc. If the gauge recognizes an
error while it is receiving a command, an error symbol is
transmitted back to the PC indicating the exact nature
of the error.
