1About
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.
2Introduction
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.

Both SENT-RS232 and SENT-CAN can be powered over CON 1: pins 8 and 9. CAN variant can also be
powered via CON 2: pins 9 and 3. All GND pins are connected throughout the device. Hence, there is
no galvanic isolation.

4.4.2 SENT-CAN
The SENT-CAN device offers two possibilities to power the device - over CON1 (like SENT-RS232) or
over CON2 (DSUB9).
Figure 4 SENT-CAN Power
4.5 CAN Bus Termination
The SENT-CAN does not have an internal termination resistor on the CAN bus. Therefore, a proper
termination of the CAN bus is needed. The user needs to make sure the CAN bus is properly terminated
at both ends.
Figure 5 SENT-CAN Bus Termination
4.6 Factory Reset
The reset button is located on the side of the device. For resetting to factory defaults, power the
device, wait a few seconds and then press and hold the button for 10 seconds. The button can be
pressed by tweezers or a pen.

5.1.3 Connect the Device
1) Click on Connect button
2) If the gateway is correctly powered and connected to the computer, its serial number and
firmware version, and the current configuration will be loaded:
5.2 Channel Configuration
The gateway has two independent SENT channels that can be configured in “SENT Configuration”
tab. After modifying the configuration, don’t forget to write it into the gateway by clicking to “Write
Configuration” button!

[e-mail]
You can also save the SENT and analogue channels configuration into gateway’s EEPROM, which
makes the gateway to load this configuration on power-up.
5.3 Start Channel
After a configuration is written into the device, one or both channels can be started.

5.4 Transmit Message
If your configuration contains at least one Tx channel, you can fill data to send in Transmit tab. Fill
your data and click to Transmit button.
You can prepare more messages by adding more rows. You can also remove them with Remove Row
button.
The table above do not behave as a scheduler. Only one row will be periodically transmitted onto
the SENT bus.
