Description
NET-7M Communication Interface
The NET-7M provides a Style 7 com-
munication interface between the main
MXL and multiple remote panels in an
MXL System using two separate RS-
485 pairs. Each NET-7M, except the
NET-7M connected to the MMB-1/-2,
electrically isolates the pairs from the
local power supply and isolates ground
faults to a single remote panel. The
MMB-1/-2 provides ground fault
detection for the two pairs.
Each NET-7M connected represents
one network drop on the MXL System.
There can be a maximum of 32 drops.
NET-7s and NET-4s cannot be
combined in the same system.
NIM-1R Network Interface Module
The NIM-1R provides a new communi-
cation path for the following:
When used as a networking interface
the NIM-1R supports the connection
of up to 63 MXL Systems. This new
network also supports a Network
Command Center (NCC) that monitors
all the MXLs in the networked group.
The NIM-1R supports both Style 4
and Style 7 connections. In the
event of an NIM-1R communication
failure, each MXL System continues
to operate as a stand-alone panel.
The NIM-1R can also be configured
as an RS-232 or RS-485 two wire
interface to foreign systems. This
operation is called FSI (Foreign
System Interface). The FSI responds
to a protocol and gathers informa-
tion about the MXL status. The
interface supports both single MXL
