Temposonics I transducer users
• Connect the transducer '+ interrogation in' wire to the ‘MDT Cmn’ pin and the
transducer '- interrogation in' wire to the '-Int' pin.
• CONNECT NOTHING TO THE '+Int' PIN OF THE RMC.
• Connect the transducer return plus wire to the '+Ret’ pin on the RMC and the
transducer return common wire to ‘MDT Cmn’ on the RMC.
• CONNECT NOTHING TO THE '-Ret' PIN OF THE RMC.
• Some Temposonics I transducers from MTS have 200 Ohm termination
resistors installed between their interrogation pins and common. If yours do
not, it may be necessary to install them as close to the transducers as possible to
reduce electrical noise in the system.
