COMMUNICATION CONFIGURATION AND CONNECTION
11.1
ILLUSTRATION
HAT553V dual power transfer controller has RS422 communication port, USB communication port.
Between them RS422 communication port allows to connect LAN of open structure. Communication
port applies Modbus communication protocol, by the running software on PC or data collecting system,
to provide a simple and practical dual power transfer management method of factories,
telecommunication, industries and civil buildings, realizing "remote control, remote measuring, remote
communicating" functions of dual power monitoring.
