Precautions for connection of coaxial cable
Before connecting or disconnecting the coaxial connector, touch a grounded metal
object to discharge the static electricity from the human body.
Failure to do so may result in a MELSECNET/10 communication unit malfunction.
1 Mount the optical fiber cable to the MELSECNET/10
communication unit.
1 Mount the F-type connector to the MELSECNET/10
communication unit.
2 Mount the coaxial cable to the F-type connector.
3 If the MELSECNET/10 communication unit is
terminal station of the network, be sure to connect a
terminating resistor (sold separately: A6RCON-R75)
to the F-type connector.
