3.2.4 om[#]<cr>:Set/Read number of lanes to be used
This command masks off the lane specified until it is reset by either an ‘om0’
command, ‘on’ command or power is cycled on the unit.
As an example, you may want to mask out the second and fourth lanes
because the cars are being disqualified for any reason. You would send an
“om2<cr>” and then an “om4<cr>” to mask out the lanes. The Finish Line will then
respond with a string that includes results for every lane, however the masked lane
will be sent as a 9.9999 (decimals are set to 4) and the placement will be a space (‘
‘) such as:
“A=1.3453a B=9.9999 C=1.4324b D=9.9999 E=1.5443c F=1.6355d”.
To reset the number of lanes used, you may either set it back to the number
of lanes available, for example with the ‘on6’ for a 6 lane track, or reset it with the
‘om0’ that will reset the masks so that all lanes are active. All of the other
parameters are persistent across a power cycle because they are stored in non-
volatile memory. The mask lanes parameter is NOT persistent. Upon power up,
using the ‘on’ or the ‘om0’ command the mask will be reset to use all lanes.
