    Safety Warnings. Netsys’ NHG-420M and NHG-200S are the latest technological innovation of G.hn wave 2 Ethernet over coaxial managed Master and Slave (client) respectively. The NHG-420M Giga Ethernet over Coax Master connects with the NHG-200S MDU Slave, supporting both 10/100/1000Mbps Ethernet and coaxial cable connections for MDU and MTU applications.

  • Page 4: Safety Warnings

     Use ONLY the dedicated power supply for user device. Connect the power to the right supply voltage (110V AC used for North America and 230V AC used for Europe, NHG-420M/S supports 12 VDC power input).  Place connecting cables carefully so that no one will step on them or stumble over them. DO NOT allow anything to rest on the power cord and do NOT find the product where anyone can work on the power cord.
