Wiring Instructions
• Connect both the +Clock and -Clock between the MA module and transducer for the
clock signal.
• Connect both the +Data and -Data between the MA module and transducer for the
data signal.
• Connect the transducer DC ground to Cmn. Each axis has two Cmn pins. Either of the
2 pins may be used. The Cmn must be connected to the transducer, or the signals will
not be read correctly!
• The transducer power supply is not provided by the RMC. The user must supply a
power supply. The power supply common may be connected to the same common that
is connected to the RMC70 CPU Cmn.
