The Ethernet Converter Kit is required to interface
between the

network and an Ethernet local
area network (LAN). This allows
L Connection
software to
access L Connection products through an Ethernet port
instead of connecting directly or through a modem. See
figure 1.
The
L Connection
network provides direct digital
communication to a single or network of
L Connection
products such as
IMC (M1−x)
,
M2
and
M3 Prodigy
®
,
NTC
rooftop unit controllers,
BC
building controllers and
NCP
network manager.
NOTE:
Unit controller and network control panel software
are ordered separately.
There are two available options (Option 1 or 2) for
setting up this device that are discussed further on in this
