Temposonics I transducer users:
For the negative interrogation version of this transducer, connect the transducer '+ interrogation in' wire to the
MDT Common pin and the transducer '- interrogation in' wire to the '- Int' pin. CONNECT NOTHING TO
THE '+ INT' PIN OF THE MMC120. Connect the transducer return plus wire to the '+' return pin on the
MMC120 and the transducer return common wire to MDT Common on the MMC120. CONNECT
NOTHING TO THE '- RETURN' PIN OF THE MMC120.
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.
