INSTALLATION AND OPERATION MANUAL
CNFE2MC2C[/M]
10/100MBPS ETHERNET ELECTRICAL TO OPTICAL
MEDIA CONVERTER WITH CONTACT CLOSURE RELAY
v1.0 Jan 2012
The ComNet™ CNFE2MC2C[/M] Ethernet 10/100Mbps Ethernet media converter is
designed to transmit and receive 10/100 Mbps data and bi-directional contact relay
over multimode or single mode optical fiber using sold-separately Small Form-Factor
Pluggable (SFP) modules to select distance and connector type. The electrical interface
will Auto-Negotiate to a 10 Mbps, or 100 Mbps Ethernet rate without any adjustments.
The optical interface operates at a 100 Mbps Ethernet rate. It can be one-to-one
mapped over Ethernet or controlled via a PC. Included is a driver that allows the
CNFE2MC2C[/M] to read or write contact information from a PC-based application.
A software utility allows customers to search for this device when installed on the
network. The CNFE2MC2C[/M] supports Windows® Discovery.
Open source com0com TCP/IP protocol is supported for any customer PC applications
to communicate with the units over the Ethernet. The software utility allows customers
to create virtual com ports for each module installed on the same subnet.
These media converters are environmentally hardened to operate in extreme
temperatures. LED indicators are provided to determine equipment operating status.
The CNFE2MC2C[/M] has a normally-open Fiber optic link alarm relay output.
The CNFE2MC2C[/M] small package size allows the unit to be installed in those
locations where space is at a premium, either wall or rack-mounted, or may be DIN-rail
mounted by the addition of ComNet model DINBKT1 adaptor plate.
