About
This document contains a description of the hardware’s properties and general instructions for
using
the SENT-RS232 and SENT-CAN with a computer with the SENT Gateway Analyser application, or for
connecting the gateway to another system.

Introduction
Both
SENT-RS232
and
SENT-CAN
gateways offer two bi-directional SAE J2716 (SENT - Single Edge
Nibble Transmission) channels. The SENT-RS232 features a RS-232 interfaces, whilst SENT-CAN offers
a CAN bus interface.
The gateways also offer two precise analogue outputs (12-bit, 0 - 4.095 V) that can be mapped onto
incoming SENT data. Conversion parameters can be configured. This allows an easy way to convert
signal values from SENT directly into an analogue voltage value.
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.
An intelligent filtration of incoming SENT frames has been introduced so that RS-232 or CAN
communication does not get overloaded. The CAN variant offers configurable CAN Identifiers for both
TX and RX which allows multiple devices to be used simultaneously on the same CAN bus. The device’s
firmware is upgradable from PC.
