RadioFrame Networks Inc RFU7 Manuel D’Utilisation

If the RFS is to be operated in an iDEN configuration, the NCU must be 
connected to a Motorola integrated Site Controller (iSC). Depending on the 
system configuration, the RFS will obtain its timing either from the iSC or from a 
direct connection from the NCU to the building’s GPS antenna.  

Connect the NCU to the iSC 

The iSC is available in two models: iSCII and iSCIII. Complete the appropriate 
procedure,  “Connect the NCU to the iSCII” or “Connect the NCU to the iSCII”.  

When connecting the NCU to an iSCII, an Ethernet Media Converter must be 
installed between the iSCII and the NCU. The Ethernet Media Converter is 
shipped in its own container with all the cables necessary to install it. 

Lay or mount the Ethernet Media Converter on any flat surface and plug it into 
an approved power source (see the following illustration). 

Set the Terminator switch on the front of the Ethernet Media Converter to “On” 
and set the MDI switch to “MDI-X”. 

Connect Port 1 on the front of the NCU to the 10BaseT port (RJ45) on the 
Ethernet Media Converter using the provided straight-through CAT 5 cable. 

Connect the ELP slot on the back of the iSC to the 10Base2 port (BNC) on the 
Ethernet Media Converter using the provided 10Base2 cable (50 ohm coaxial 
cable with two male BNC connectors).
