The 619 SRI is an eight-port radio communications and configuration hub that is designed to provide cost effective interoperability between radios from different manufacturers and with varying signalling requirements. Using Omnitronics' proprietary technology, “DHC” (Dynamic Hub Configuration), the 619 SRI brings together CTCSS, in-band keying, VOX, SELCAL and DTMF with a number of programmable configuration overlays. This provides users with the ability to dynamically configure radio networks to suit operational requirements and, through a Windows graphical user interface, makes radio interconnection easier than ever before.
