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 together 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.
