As shown above in the figure Gospell qam GQ3680 have mainly three sections in its rear panel. Each section contains 2 RF ports and 2 GbE ports where GbE ports are for inputs and RF ports for outputs. In these 2 RF ports there is one RF Out Main and other is RF Test Port. So we need to get our output from RF Main Port only because RF Test port gives -20 dB less RF power. So this port is used as testing. This device is configured so that each RF Main Out provides maximum 16 Transport Streams as output. While newer version of this QAM provides 24 Transport Streams per RF Out port. Both GbE ports can be used as IP input of each section. Here each section is denoted by RF Card like RF Card 1 , RF Card 2 and RF Card 3 of this QAM.

Do not forget to connect your headend’s earthing cable with this QAM’s earthing terminal for safety point of view.
