The SAE J2716 (SENT) to RS-232 bus gateway features two bi-directional SENT (Single Edge Nibble Transmission) channels, two analogue output channels, and a RS-232 port. The interface’s flexibility allows the user to use it as a PC interface / SENT data logger, a gateway for PLC or a test system, and generally for SENT communication monitoring and simulation. The analogue outputs offer the possibility to directly convert SENT data frame signals into an analogue voltage.

Fast, Short Serial, and Enhanced Serial message formats are supported. The user can configure channel parameters (direction, tick time, nibble count, filtration) and store the configuration into the device’s non-volatile memory. Each SENT channel can be configured independently to suit all possible use cases: 2 RX channels / 1 RX and 1 TX channel / 2 TX channels.
The converter offers two analogue output channels (12-bit DAC) that can be used to directly convert inbound SENT data frames into an analogue voltage. An analogue output channel can be mapped on any SENT channel. and the conversion parameters are fully configurable: StartBit, BitLength and a linear transfer function: Multiplier, Offset, Min/Max.
An intelligent filtration of incoming SENT frames has been introduced so that the RS-232 communication does not get overloaded. The device’s firmware is upgradable from PC.
A PC application for configuring the device and for monitoring, logging and simulation of SENT communication is available for free. The device provides a communication protocol over RS-232 so that the user can easily integrate the device into an existing system, such as test benches, HiL rigs and End-of-Line testers. The protocol provides function to configure the device’s SENT and analogue channels and to transmit and receive SENT Fast and Slow messages. A CRC fault injection into both Fast and Slow messages is also possible.
Software and System Integration
- Communication protocol for integration into existing systems
- Free-of-charge “SENT Gateway Analyser” PC application for configuration, reception, transmission and logging
note: The SENT Gateway Analyser application will work with any RS-232 port.
- .NET SDK (DLL) for software integration allows to configure the gateway, start/stop SENT channels, and transmit/receive fast and slow SENT messages.
- Analogue output channels to connect SAE J2716 bus to systems without SENT support
- Device’s firmware upgradable from PC
