Over the Internet Programming (OTIP) enables you to program Viking mobile radios 
remotely using IP-based network services. It works with both wired (Ethernet) and 
wireless (Wi-Fi) networks.

There are inherent security risks with exposing your radios on a LAN or WAN. Your 
system administrator or IT department should be made aware that Viking mobile radios 
using OTIP will periodically use Multicast DNS and DNS-Based Service Discovery to 
coordinate availability. You may choose to completely disable OTIP functionality by not 
ordering the OTIP option.

Because OTIP-enabled radios are available to all computers on the network, you should 
use network security policies with upload/download restrictions. 

OTIP has no special restrictions for voice announcements. You can use the OTIP interface 
to quickly transfer large codeplugs with many voice announcements. 

Armada supports industry-standard (SSH) encrypted transfers when using USB, Ethernet 
or Wi-Fi network connections. If Wi-Fi is configured, you must use WPA2 Pre-Shared 
Key (PSK). 

Armada may show a radio OTIP-connected when it is not. This is due to the nature of 
service discovery on IP networks. Here are a few examples of scenarios in which this may 
happen. There may be other such scenarios also:
