Patient Module Front-ends
The patient module shares the same parameter front-ends as the Toco
+
transducer, with the exception
of the Toco front-end.
Avalon CTS Interface Cable (TMIF)
The Avalon CTS Interface Cable contains the Telemetry Module Interface (TMIF). The TMIF shares
the signal processing circuitry with the rest of the Avalon transducers, with the exception that it has no
front-end board. The TMIF is responsible for converting the analog signals from the parameter front-
ends of the Avalon CTS transducers into digital signals for transmission to the fetal monitor.
