The optional PREVIDIA-C-COM-LAN module, once installed inside the cabinets of PREVIDIA-COMPACT control panels, it provides two RS232 ports and two RS485 ports for the connection of remote communicators, using the following protocols. RS232 (ESPA444, Web Way One, ASCII printer, SmartLoop format, Plus II printer format, ASCII without controls); RS485 (PASO, SMART-485-IN). In addition the PREVIDIA-C-COM-LAN module provides a socket for connection to the Ethernet network, by means of this second connection (the motherboard and the module must both be connected to the same network) the following advanced TCP-IP functions are implemented: E-mail management; Interactive WEB page with graphic maps for full management of the control panel; Video Verification through connection to IP cameras with ONVIF protocol; BACnet protocol (subject to PRE-BAC-LIC licence); Interfacing to EVAC TUTONDO systems (via TCP-IP)
