2-2 Overview 
SG 2000 Installation and Operation Manual   
Port Locations 
The five housing ports, shown in Figure 2-2, provide connection for coaxial cables. Note that the 
housing ports are not labeled the same as the ports on the RF chassis. Side-by-side connector fittings 
are limited to .750 inches at ports 1 and 2 and/or ports 3 and 4. These ports are protected by factory 
inserted threaded plugs or plastic cap plugs which are discarded when the cable connectors are 
installed. Port 2 is used only for connection to an external 60 Vac or 90 Vac power supply. Port 4 is 
unused. 
Figure 2-2 illustrates a front and end view of the housing and port locations:
