Radio Management (RM) allows you to view or define the radio's OTA (Over The Air) Fixed IP Address (FIP) for all codeplug (record / rows) within this Radio View. When a radio's IP Address is known it can be used for direct Device Programmer - POP25 / OTAP to radio communications, eliminating the need for ARS, which is also known as FIP Mode. 

APX RM (Radio Management)

Configure FIP (Fixed IP Address) Mode Programming:

1. When a Read or Write job is created for a radio in RM, the Connection Method selection must be set to "POP25" or "ANY".
   2. The Device Programmer (DP) / Device Monitor allows for a FIP (Fixed IP Address) Mode...
   When this OTA Fixed IP Address is defined for a radio (Radio View > OTA Fixed IP)
   AND
   When the DP's Communication Method is set to "Over the Air", 
   AND
   when the DP's ARS Alias is set to "None" 
   (In this scenario, once the presence of a radio with a defined OTA Fixed IP Address is DP detected, only FIP Mode jobs are sent from the RM Server to be executed.)

Selections are valid when the following is true:
The four octets must be in the range: [1-223] . [0-255] . [0-255] . [0-255], and
this IP Address cannot be the Limited Broadcast Address: 255 . 255 . 255 . 255
And, the IP Address must be a valid Class A, B, or C address:
The IP Address is considered Class A when octet 1 is between 0-127; the Network ID is then this first octet:
when the IP Address is Class A, then the IP Address can be 1 . 0 . 0 . 1 to 126 . 255 . 255 . 254
when the IP Address is Class A, then the IP Address cannot be 0 . XXX . XXX . XXX or XXX . 255 . 255 . 255 or XXX . 0 . 0 . 0 or 127 . XXX . XXX . XXX.
The IP Address is considered Class B when octet 1 is between 128-191; the Network ID is then the first 2 octets:
when the IP Address is Class B, then the IP Address can be 128 . 1 . 0 . 1 to 191 . 255 . 255 . 254
when the IP Address is Class B, then the IP Address cannot be 128 . 0 . XXX . XXX or XXX . XXX . 255 . 255 or XXX . XXX . 0 . 0.
The IP Address is considered Class C when octet 1 is between 192 -223; the Network ID is then the first 3 octets:
when the IP Address is Class C, then the IP Address can be 192 . 0 . 1 . 1 to 223 . 255 . 255 . 254
when the IP Address is Class C, then the IP Address cannot be 192 . 0 . 0 . XXX or XXX . XXX . XXX . 255 or XXX . XXX . XXX . 0
