LIFETIME WARRANTY WWW.COMNET.NET TECH SUPPORT: 1.888.678.9427
FEATURES
› Full duplex transmission of 10/100 Mbps Ethernet:
(2) 10/100BASE-TX ports and
(1) 100BASE-FX SFP port
› Extended ambient operating temperature range of -40º to +75º C,
for use in virtually any environment. Optional conformal coating
available for humidity with condensation or airborne particulate
matter environments

The ComNet CNFE3FX1TX2C/M series is an industrially hardened three-port intelligent switch with light management
functionality and an integrated contact closure server. The 100BASE-FX port supports conventional CAT-5e/CAT-6
copper or optical transmission media by selection of the appropriate ComNet SFP* module. A summary fault alarm
provides indication via a form c relay in the event of loss of optical link or operating power. The 10/100BASE-TX ports
support both auto-negotiation and automatic MDI/MDI-X crossover for full and half-duplex operation; manual MDI/
MDI-X switching is not required. The integrated contact closure server is available with 4 or 8 channels and supports
individual user selectable wet or dry inputs. Form A relay outputs feature individual user selection of normally open or
normally closed operation via the built-in web GUI. The contact server supports 4 modes of operation including one-
to-one, one-to-many, many-to-one and stand-alone use through JSON frames for integration into third party systems.
The internal/self-contained 9 to 36 VDC or 24 VAC power supply features redundant power inputs, for the highest
possible reliability. The simple to install, CNFE3FX1TX2C/M Series is DIN-rail or panel-mountable, and is ideal
for mission-critical applications where very high levels of reliability and network availability are of the utmost
importance.
