Fast CH
• Up to 6 nibbles (24 bits) of data can be sent.
• The size of the value is expressed with the pulse width. 0: 12 ticks to 15: 27 ticks
Slow CH
• Composed of bits 2 and 3 of the S&C (Status & Communication) nibble of multiple
Fast CH data.
• Sends data that changes slowly and error information.
• Three types of formats (data size 8-bit, 12-bit, 16-bit) are available.

Message (Frame)
This module reads SENT signals based on SAE J2716, extracts the specified portion of the SENT message,
converts it to time series data, and displays its waveform. This module has two ports. For each port, the
waveforms of up to 11 sub channels can be displayed.
For SENT signal monitoring using a SENT monitor module, the items that have to be set include format, error
channel, probe, data extraction conditions, sub channel display range, unit of measurement, trace settings, and
scaling.
