If more than one DMC Sigma2N Controller is in the CAN network, make sure only one of them
has this parameter set between 1 and 6. This will be the DMC Sigma2N Controller sending the
drive and BDI information to the Display (and therefore the Display Master).
In case of Dual motor configuration, the Dual Motor master must be also the Display master
(i.e. the one with this parameter set different than 0).
M7.4-3 Display refresh rate “RefRate”
This parameter sets the refresh rate of the messages used to communicate with the DMC Display or with the
iGauge master/slaves. It is not suggested to change this value unless there is too much traffic on the CAN bus.
