RS232 Messages
The PLM transmits RS232 status messages at a rate of 20 times a second.
If the PLM is configured as a CAN Collect Master then the transmitted message
contains the Lambda values for the master PLM and up to 15 slave PLMs.
If the PLM is not configured as a CAN Collect Master the transmitted message
contains Lambda values and diagnostics for the PLM.
Appendix N – RS232 Message Format describes the format of the RS232
Messages. Note that the number of decimal places for calibrated sensor
readings depends on the selected output table in the PLM configuration.
The transmitted messages conform to the MoTeC generic data protocol and are
sent at 9600 baud, 8 data bit, no parity, 1 stop bit (9600, 8N1).
