Communication
The types of communication available to the PVSG-IQAN are Controller Area
Network (CAN), Ethernet, Modem (GSM), Wi-Fi, and USB host/device.
7.1. Controller Area Network
The PVSG-IQAN has 2 CAN communication ports available.
The hardware provides controller area network (CAN) communication according
to the SAE J1939 specification, making the PVSG-IQAN compatible with CAN-
based protocol through software.
CAN communication is used to communicate the status of multiple modules that
are connected in the same network.
7.1.1. CAN capabilities
The CAN communicates information at a baud rate of 250 kbps. Lack of regular
CAN communication is an indication that there is either a problem with a module
in the network, or a problem with the CAN bus.
