Installation NOTES
Install Coax Copper
STAR TOPOLOGY
• MAXIMUM coax segment to active hub is 600 meters (2000
feet) on RG-62 cable; minimum does not apply.
BUS TOPOLOGY
• Devices attached to coax bus must be located AT LEAST six
(6) feet apart.
• MAXIMUM coax bus length is 300 meters (1000 feet);
minimum is 1.8 meters (6 feet).
• Device(s) attached to EACH END of bus must be terminated.
NOTE: If the media converter is installed at one end of the
bus, use the configuration switch to terminate the media
converter.
CONFIGURATION SWITCH
NOTE: Set configuration switch (located on the side of media converter)
according to site installation requirements:
Switch 1 NOT USED
Switch 2 UP = OFF Media converter TRANSFERS signal
DOWN = ON Media converter TERMINATES signal.
Install Fiber
• Connect one end of first fiber cable to AR-CF-02 media
converter TX connector.
• Connect other end of that fiber cable to second AR-CF-02
media converter RX connector.
• Connect one end of second fiber cable to AR-CF-02 media
converter RX connector.
• Connect other end of that fiber cable to AR-CF-02 media
converter TX connector.
Power
• Locate correct power supply adapter for site installation.
• Connect media converter power connector at end of power
supply adapter cord to AR-CF-02 media converter power
receptacle.
• Connect 2-prong or 3-prong external power connector on
other end of power supply adapter cord to external AC power.
