some data types to CAD and others to CFD.
Because they are represented as whole numbers, the best choices of data to send to
the CAD field are:
BL
OPT_A
OPT_T
The best choices to send to the CFD field are:
BIAS
TTB
TTL
The time fields will have a dot in the display, such as 3.40. In the case of the time fields,
this means 3 minutes and 40 seconds. In the case of an angle, such as bias, it
represents 3.40 degrees.
The NXR series instruments have the ten custom data fields, so any type of data
generated by the Race Box can be sent to any of those ten custom fields.
The Race Box is told which data to send to which field in its configuration file. Here is
an example from the config file:
CAD_IS=BL
CFD_IS=TTB
;
CAD_OS=OPT_T
CFD_OS=BIAS
The first line, CAD_IS=BL, means that the BL (boat length) data calculated by the Race
Box will be sent to the CAD field of the Nexus network while the starting sequence is in
progress. In short, CAD_IS means CAD field while in sequence. Likewise, CFD_IS
means CFD field while in sequence. Conversely, CAD_OS means CAD field while out
of sequence and CFD_OS means CFD field while out of sequence.
Therefore, before you begin the starting sequence and after the sequence ends, the
example above will cause the optimum true wind angle to be sent to the CAD field while
the start line bias will be sent to the CFD field. As soon as you trigger the start timer,
CAD will begin displaying boat lengths to line (BL) and CFD will begin displaying time to
burn (TTB).
If you prefer that no data be sent to a field, you can set it to “OFF” like this:
CFD_OS=OFF
