Appendix A. CR23X/CR10X Programs
11 1 Multiplier, always 1.
12 0 Offset, always 0.
P15 parameters 4, 5, and 10 are somewhat variable. When using a CR23X,
parameter 4 can be set to 05, 06 or 07 depending on what control ports are
used. A CR10X can use control ports 1 through 6. Wiring of the
communication cable depends on the selection for parameter 4. With a CR23X
the GPS transmit wire is connected to the control port selected in parameter 4.
With a CR10X, the GPS transmit wire is connected to the control port 1 higher
then the control port listed in parameter 4.
P15 is executed when the PPS signal drives control port 8 high. P15 will wait
until one of three conditions is met: the time-out listed in parameter 9 has
expired, the maximum number of characters in parameter 8 have been read, or
the termination character listed in parameter 7 has been read.
P15 parameter 10 is the first input location you wish to store GPS data in.
Fifteen sequential input locations will be used to store time and position.
