1.1: Overview of the ProtoCom/ProtoCom-Lon Gateway
The ProtoCom/ProtoCom-
Lon is an external, high
performance Building Auto-
mation System (BAS)
multi-protocol gateway that
is pre-configured to auto-
matically communicate
between Electro Industries/
Gaugetech (EIG) meters
and GE’s PQMII meter, and
various building automation
protocols.
The ProtoCom supports: BACnet® MS/TP, BACnet®/IP, Johnson Controls’ Metasys®
N2, EtherNet/IP and DF1, and Modbus® TCP protocols; and the ProtoCom-Lon sup-
ports the LonWorks® protocol. With the ProtoCom, the meters’ Modbus communica-
tion is converted into BACnet or other popular BAS protocols. With the ProtoCom-Lon,
the meters’ Modbus communication is converted into LonWorks® protocol.
The ProtoCom/ProtoCom-Lon enables communication with Building Automation Sys-
tems (BAS) and Sierra Monitor Corporation (SMC) Cloud. SMC Cloud enables remote
device control, data access, and troubleshooting.
The ProtoCom/ProtoCom-Lon connects to either the EIG and GE meter’s RS485 port
or via network connection to the Ethernet port. The ProtoCom/ProtoCom-Lon unit also
has an auto-discovery mode that automatically identifies and configures meters con-
nectedvia the RS485 serial port. with auto-discovery, you do not need to do manual
mapping of the meter’s Modbus points.
The ProtoCom/ProtoCom-Lon is shipped as a kit (ProtoCom-KT/ProtoCom-Lon-KT)
which consists of the unit, a power supply, a communication cable, a one page Quick-
start guide, and this manual on a CD.
