AT-NODE - Network node device
AT-NODE/.. device is an active network node which can accumulate the signals comming from localy plugged external device(s) as well as the transmission comming from the network backbone which AT-NODE/.. is a part of. Depending on its internal equipment data can be transferred to/from the device using the wireless transmission as well as the fiber optic cable, and cooper cable. Data transmission is based on the Ethernet protocol. Device is done as per ATEX requirements for group I. Its internal circuits are designated as ‚ia’ which makes it capable of working under any mining conditions. Its external enclousure provides it with IP65 protection level. It is possible for the device to be fitted with battery blocks in order to provide its functionality when the main power is off.
