DESCRIPTION

The ComNet™ CNFE8(X)COE transmits eight contact closures
over an Ethernet network. It is available with a 10/100TX RJ45
Ethernet connector and an SFP fiber optic interface. These
units can be one-to-one mapped over Ethernet or controlled
via a PC. Included is a driver that allows the CoE to read or
write contact information from a PC based application. A
software utility allows customers to search for this device that
is installed on the network. The CNFE8TCOE transmitter and
CNFE8RCOE receiver support Windows
depend on which SFP (Small Form Pluggable) module is used.
The CNFE8(X)COE is environmentally hardened to operate
in extreme temperatures. LED indicators are provided for
confirming operating status. Packaged in the ComNet ComFit
housing, these units may be either wall, rack, or DIN-rail mounted
with the addition of the ComNet DINBKT1 adaptor plate.
