Description
The FastECoax 7501 transports Ethernet over 75Ω coaxial cables. The link consists
of a pair of converters connected together via coax and terminated at each end
with a RJ45 socket. Together the converters create a virtual UTP cable that is
indistinguishable from any other UTP cable link. Power for the internal electronics
can be supplied either using the Power over Ethernet (PoE) standard or via a
separate AC adaptor.

Setup:
Installation Instructions
 Connect Head End and Camera Side converters to ends of BNC terminated
Coax cable placing Head End at the end where power is to be supplied
 Connect CAT5/6 patch cable to each converter
 Connect Camera Side Converter patch cable to IP camera/ DVR/ Switch/ PC
 Connect Head End Converter patch cable to PoE injector, PoE enabled Ethernet
switch or local Ethernet infrastructure
 In non-PoE systems connect DC Adaptor to Head End Aux Power input
Important
The FastECoax7501H and FastECoax7501C
converters must have 75Ω (+/- 3Ω) impedance.
The Characteristic impedance of the coaxial
cable and connectors must all be 75Ω. Only use
only BNC connectors that are clearly marked as
“True 75Ω”. The illustration (right) shows the
difference between a 50Ω versus a 75Ω
connector.

Power options:
There are a number of ways to power the converters:
 Head End converter can be powered via PoE, or via DC adapter
 Camera Side must be powered by the Head End over the coax cable
 An IP camera can be powered via PoE (via UTP from the Camera Side),
via the Aux power out of the Camera Side, or using its own power adapter
!
Do not connect the Camera Side to a PoE power injector, or to a power
adapter (the Camera Side power connector is output only).

Troubleshooting:
When the FastECoax7501 converters are paired they create a virtual UTP cable.
The LEDs on the converters will only light if the complete link is established from
the Ethernet device at one end of the cable to the Ethernet device at the other
end. Once the whole link is established the Yellow LED will light and then flash to
show Ethernet traffic.
Link establishment is also transparent. If a device at one end of the cable is only
capable of operating at 10Mbps, the devices at each end of the link will negotiate
the link to be 10Mbps. In this case the green LED will remain off, showing a
connection at 10Mbps. The same happens for full/half duplex.
The FastECoax7501 supports Auto-MDI/MDI-X meaning that both straight and
twisted patch cables will work. Only use short patch cables, less than 3 meters in
length.
The Characteristic impedance of coaxial cable and BNC connectors must all match.
The FastECoax7501H and FastECoax7501C Converters require 75Ω (+/- 3Ω)
impedance. Most problems are caused by using poor quality BNC connectors that
are not designed to be 75Ω. Always make sure that the BNC connectors are
marked ‘True 75 Ω’.
Symptom
Converters will not connect
Converters will not connect
Specified range not achieved
Specified range not achieved
Slave Converter is not powered
Master Converter is now powered
Probable Cause
Ensure coax is 75Ω impedance
Ensure BNC connector is 75Ω impedance
Ensure coax is 75Ω impedance
Ensure BNC connector is 75Ω impedance
