RLE Technologies

Description

The Protocol Converter connects directly to equipment and converts SNMP, BACnet, and Modbus protocols to one or more of these same protocols for integration into a building management system (BMS) or network management system (NMS).

RLE offers two Protocol Converters:

  • The Protocol Converter (FDS-PC) has one EIA-485 port.
  • The dual port Protocol Converter (FDS-PC-DP) has three EIA-485 ports for extended Modbus polling over multiple trunk lines.

The Protocol Converter is ideal for situations where data from monitored equipment is incompatible with the protocols used by the BMS or NMS, such as in cases where legacy monitoring systems are present.
