Appendix F — 2-Way Serial Communication
All GasFinderMC units with software version 1.10e (November 2012) or later have the ability
to be controled remotely with commands passed through the data cable. This cable requires
three conductors and is marked with a yellow band. The remote control enables the user to
alter various parameters without entering the menu in the
GasFinderMC with the ensuing
time delay while the system recalibrates.
If the user is operating with GasViewMC ver 4.02 or later, the commands are done
automatically, otherwise a terminal program such as Hyperterminal is required.
All commands adhere to the following format: gf[<cc>][<n>][? | = [<m>]]
lowercase “gf” preceeds all commands. •
<cc> is a 2 character command acronym. •
<n> is a single digit channel number. •
Parameter access commands are followed by ? or = for get and set respectively. •
‘set’ commands take a parameter <m>. •
There are no white space characters to keep the interface lean. •
All commands are terminated by carriage return (Enter). •
Commands are responded to using the • GasFinderMC checksummed output line
convention “$GF{CER | COK[,<n>]}*XX” where “XX” is the hexadecimal checksum, ie
“$GFCER*55” for an unrecognized, malformed or out of range command.
