The V7111 12 PORT differs from the V7111 14 PORT and V7111 18 PORT in that its configuration
excludes the RS-232 connector, the Lifeline option and outdoor protection.
As these units have similar functionality (with the exception of their number of channels and
some minor features), they are collectively referred to throughout this manual as the V7111.
