5.8.15 Pro II-SENT-6 Rev. E
The module Pro II-SENT-6 Rev. E provides 6 input channels using the SENT
protocol (Single Edge Nibble Transmission) and analyzes the incoming SENT
signals on all 4 channels automatically. Additionally there are 4 digital inputs
and 4 digital outputs with TTL levels.
The description of the SENT module is divided into the following sections:
