HHD’s DAQ is a device that collects data and connects to a centralized management server (NMS) to help the operation and exploitation of M&E equipment in stations and make it more efficient, faster, and more reliable. It collects data on M&E equipment, such as power cabinets, LIB batteries, machines, power generation, electronic meters, and ventilation, via RS485/RS232 communication and sends all that data to the server via Ethernet protocol (SNMP, http).
