The ComNet CNGEUMC4+2(TX,RX)/M unidirectional media converter with Link Guardian limits network traffic to one way communication between source and destination networks preventing cybersecurity attacks from a non-secured entry point in the network from reaching a secured part of the network. The CNGEUMC4+2(TX,RX)/M provides four 10/100/1000Base-T(X) copper ports and two 1000base-FX SFP ports.

The unidirectional media converter also features Port Guardian which provides additional cybersecurity protection by enabling physical port lockout in the event that an existing cable is disconnected and prevents a potential network incursion using common spoofing techniques.

Also included is the ComNet exclusive functionality for easy field deployments including DIP Switch based operation of RSFP (redundant SFP) for creating redundant fiber connections and MUX Features for port isolation preventing network video flooding of multicast traffic.

Features for CNGEUMC4+2(TX,RX)/M

  • 10/100/1000 Mbps Ethernet • 10/100/1000 BASE-T/TX electrical port • 1000 BASE-FX optical port
  • Port Guardian prevents network intrusion through intelligent physical port lockout
  • Electrical ports support Auto-Negotiation for 10Mbps, 100Mbps or 1000Mbps, full duplex or half duplex data.
  • Several features can be enabled with no programming required: - MUX - Port Multiplexing - RSFP - Redundant SFP Ports
  • SFP Ports compatible with CopperLine CL-SFP modules
  • 2 Duplex contact closures
  • Automatic MDI/MDI-X crossover
  • Designed to meet full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions, and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment.
  • The port count makes this unit ideal for those applications where rack density or shelf-space may be limited.
  • Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events.
  • Redundant AC/DC inputs for uninterrupted operation in the event of a loss of operating power or a power supply failure
  • Compact form-factor saves space in those installations where space may be at a premium.
  • Designed for wall or DIN rail mount installations (using optional DIN mounting bracket)
  • Link Guardian limits network traffic to one direction (source to destination) only
  • SFP Ports support 1000 Mbps full duplex data


  • 10/100/1000 Mbps Gigabit Ethernet
  • Perimeter Protection Surveillance Systems
  • IP Video
