In this example six different single-packet parameter group messages were observed. For each, the PGN, priority, source
address and destination address are returned.
There are also three different multi-packet messages, indicated by
EXT*
. These include an additional display item: the
length of the data message in bytes. Note that the displayed 64-bit data field does not contain any actual message data; it
contains transport protocol information including PGN and data length.
NETLOAD – Measure CAN Traffic Load
NETLOAD
{ CANport }
where
CANport
is the CAN port to measure (integer,
1-2
). If not specified, both CAN ports are measured.
This command measures the traffic load on one or both CAN ports, and reports it as a percentage of the theoretical
maximum for the bit rate in use. It should be noted that a network with a load approaching 80% is close to the practical
maximum load possible on a CAN network.
Examples
NETLOAD
CAN1 0.0 %
CAN2 7.8 %
In this case nothing is connected to CAN1, and a single ECU is connected to CAN2. 7.8% of the available bus bandwidth is
being consumed by the regular broadcasts from this ECU.
SETADDR – Set CANgate Address
SETADDR
CANport
address
where
CANport
is the CAN port (integer,
1-2
)
address
is the protocol address which CANgate should use when communicating on the specified CAN network
(integer,
0-255
, default:
0
)
For some CAN protocols, each device on the network needs to have a unique address assigned. This command allows you
to assign an address to the CANgate. Currently this will only have an effect for the J1939 protocol. Note that in most cases
the default address (
0
) can be used.
GPSBAUD – Set GPS Port Baud Rate
GPSBAUD
baudRate
where
baudRate
is the required baud rate to use on the GPS port (integer,
300-115200
, default:
4800
)
Most NMEA-0183 devices operate at 4800 baud, however some newer high speed devices operate at a faster rate. This
command allows the GPS port baud rate to be set to match that of the connected device.
The current GPS port baud rate setting is saved to flash memory so it will be restored following a power interruption.
