    5. Connect same-site radios using a null-modem cable at the radios’ diagnostic ports. 6. Connect a PC on which MDS InSite software is installed to the root radio, or to one of the nodes, at the radio’s diagnostic port. (This PC may be the PC being used to collect payload data, as shown in Figure 14.)
