1.2 General
The pressure transmitter DST P92C measures the
physical quantity pressure. The range depends on
the sensor which is used in the transmitter and
is 25–800 bar. The measured value is transmitted
on the CAN-Bus with the J1939 protocol. The
transmitter takes 1000 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 with 11-bit and 29-bit
identifiers.
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 shortcircuit. By adjusting the rise and fall times of the
CAN signals, the noise emission is minimized.
The bus termination resistor is not included in
the device.

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.

3.4 Definitions 3. 4.1 P G N
The PGN (Parameter Group Number) uniquely
identifies the Parameter Group (PG) that
is being transmitted in the message. The
Parameter Group Number (PGN) is a part of the
29-bit identifier sent with every message.

3.4.2 SPN
Each parameter used in the J1939 network is
described by the standard. A Suspect Parameter
Number (SPN) is a number that has been assigned
by SAE committee to a specific parameter. Each
SPN has the following detailed information
associated with it: data length (in bytes);
data type; resolution, offset; range; and a tag
(label) for reference. SPNs that share common
characteristics will be grouped into a Parameter
Group (PG) and will be transmitted to the network
using the same PGN.
