1.2 General
The temperature transmitter DST T92C measures
the physical quantity temperature. The range is
-40 – 150 °C for the medium. The measured value
is transmitted on the CAN-Bus with the J1939
protocol. The transmitter takes 107 samples per
second, does filtering and converts the raw value
into the output format.
The CAN 2.0B interface is able to run up to a
speed of 1 Mbit/sec.
The device supports Diagnostic Message 1 (DM1,
PGN 0xFECA, active diagnostic trouble codes,
automatically send every second), Diagnostic
Message 2 (DM2, PGN 0xFECB, previously
active diagnostic trouble codes) and Diagnostic
Message 3 (DM3, PGN 0xFECC, diagnostic data
clear/reset for previously active DTCs). Also the
DST T92C CAN SAE J1939 firmware supports
static node addressing as well as dynamically
address claiming.
1.3 CAN Interface
The device includes a Full CAN controller
specified to CAN 2.0B. The physical layer of
the 2-wire interface is specified according to
ISO 11898. The wires are protected against
short-circuit. By adjusting the rise and fall
times of the CAN signals, the noise emission is
minimized to meet the EMC requirements. The
bus termination resistor is not included in the
device.

Furthermore the device can easily configured
with a configuration vector (PGN 0xEF00) by
the customer if needed. An example dbc-file
with a default configuration to use with “Vector
CANdb++ Editor” is available on request.

3. J1939 Communication
3.1 Introduction
The Society of Automotive Engineers (SAE)
developed the 1939 standard to be the
preferred CAN for equipment used in industries
ranging from agriculture, construction, and fire/
rescue to forestry, materials handling as well as
on and off-highway vehicles. It is a high-level
protocol that defines how communication
between nodes (modules) occurs on the bus.
The 1939 network is a specific communication
system, supporting specific sets of applications
and a specific industry, rather than being
generalized.
Any electronic control unit (ECU) using J1939
is permitted to transmit a message on the
network when the bus is idle. Every message
includes a 29-bit identifier, which defines the
message priority, what data is contained within
the 8-byte data array that follows the identifier,
and which ECU sent the message.
