For CAN usage:
at high load and 30 PGNs, CPU usage is 26%
at moderate load and 30 PGNs, CPU usage is 16%
adding the reception of 10 PGNs per second increases the load by 2-3%.
The Logger port, if used by the customer to receive data, should not be run above
19200. It could drop bytes otherwise. The Logger port should be used for debugging
purposes only.
The AUX port
maximum speed is 57600 bps
may not be available on certain configurations of the Q4000/QPRO. The
Q4000/QPRO with Iridium or Inmarsat, for example, does not have the AUX port
available.
17 Load conditions
The Q4000/QPRO can perform the following actions simultaneously
:
send messages on the GSM/GPRS port at 115200 bps continuously
send messages via satellite network continuously
use MTS port at 115200 bits per second (bps)
use AUX port at 115200 bps
continuously obtain GPS fixes
run Logger port at debug level 6
access CAN bus messages by providing the desired PGN.
As long as filtering is done in foundation, a fully loaded CAN bus at 250 Kbps is
supported. Raw CAN bus filtering cannot be done at the application level
because the input queue can quickly overflow if the ORBCOMM module is
running (see Note below).
continuously run OSI protocol at 115200
perform OTA upgrades
CPU load can reach 85-90% during these loading conditions.
